Great Barrier Reef loses more than half coral cover

Great Barrier Reef loses more than half its coral cover

Population explosion of coral-eating starfish, storms and acidification of oceans causing rapid decline, study finds

 Coral cover in the Great Barrier Reef has dropped by more than half over the last 27 years, according to scientists, a result of increased storms, bleaching and predation by population explosions of a starfish which sucks away the coral's nutrients.

         At present rates of decline, the coral cover will halve again within a decade, though scientists said the reef could recover if the crown-of-thorns starfish can be brought under control and, longer term, global carbon dioxide emissions are reduced.

         "This latest study provides compelling evidence that the cumulative impacts of storms, crown-of-thorns starfish (Cots) and two bleaching events have had a devastating effect on the reef over the last three decades," said John Gunn, chief executive of the Australian Institute of Marine Science.

         Coral reefs are an important part of the marine ecosystem as sources of food and as protection for young fish. They are under threat around the world from the effects of bleaching, due to rising ocean temperatures, and increasing acidification of the oceans, which reduces the corals' ability to build their calcium carbonate structures.

         The Great Barrier Reef is the most iconic coral reef in the world, listed as a Unesco world heritage site and the source of $A5bn (£3.2bn) a year to the Australian economy through tourism. The observations of its decline are based on more than 2,000 surveys of 214 reefs between 1985 and 2012. The results showed a decline in coral cover from 28% to 13.8% – an average of 0.53% a year and a total loss of 50.7% over the 27-year period. The study was published on Monday in the Proceedings of the National Academy of Sciences journal (subscription).

         Two-thirds of the coral loss has occurred since 1998 and the rate of decline has increased in recent years, averaging around 1.45% a year since 2006. "If the trend continued, coral cover could halve again by 2022," said Peter Doherty, a research fellow at the institute.

         Tropical cyclones, predation by Cots, and bleaching accounted for 48%, 42%,and 10% of the respective estimated losses. In the past seven years the reef has been affected by six major cyclones. Cyclone Hamish, for example, ran along the reef, parallel to the coast for almost 930 miles (1,500km), leaving a trail of destruction much greater than the average cyclone, which usually crosses the reef on a path perpendicular to the coast.

The starfish problem was first recorded in 1962 at Green Island off Cairns. "When we say outbreaks, we mean explosions of Cots populations to a level where the numbers are so large that they end up eating upwards of 90% of a reef's coral," Gunn said. "Since 1962 there have been major outbreaks every 13-14 years."

         The evidence suggests that outbreaks of Cots start two or three years after major floods in northern rivers.

         In September, scientists at the International Union for Conservation of Nature announced that Caribbean coral reefs are on the verge of collapse, with less than 10% of the reef area showing live coral cover. The collapse was due to environmental issues, including over-exploitation, pollution and climate change.

         David Curnick, marine and freshwater programme co-ordinator at the Zoological Society of London, said many of the most endangered coral species around the world were also under severe pressure from the aquarium trade. "Corals are notoriously hard to propagate in captivity and therefore the trade is still heavily dependent on harvesting from the wild."."

         He said the results of the Great Barrier Reef survey were not surprising and the challenge for conservationists was to limit the localised threats to give reefs a chance to recover and develop resilience against the effects of climate change. "This is challenging but entirely achievable and there are many community-led projects around the world demonstrating this."

         Corals can recover if given the chance. But this is slow – in the absence of cyclones, Cots and bleaching, the Great Barrier Reef can regrow at a rate of 2.85% a year, the scientists wrote. Removing the Cots problem alone would allow coral cover to increase at 0.89% a year.

         Reducing Cots means improving water quality around the rivers at the northern end of the reef to reduce agricultural run-off – high levels of nutrients flowing off the land feed and allow high survival of Cots larvae. Another option is some form of biological control of populations – Gunn said there were promising results from research on naturally occurring pathogens that could keep Cots in check, but it was not ready to be applied in the field.

         He said the future of the Reef lay partly in human hands. "We can achieve better water quality, we can tackle the challenge of crown-of-thorns, and we can continue to work to ensure the resilience of the reef to climate change is enhanced. However, its future also lies with the global response to reducing carbon dioxide emissions. The coral decline revealed by this study – shocking as it is – has happened before the most severe impacts of ocean warming and acidification associated with climate change have kicked in, so we undoubtedly have more challenges ahead."

The Romney Plan for...ENERGY INDEPENDENCE

The Romney Plan For A Stronger Middle Class: ENERGY INDEPENDENCE

August 23, 2012

http://www.mittromney.com/sites/default/files/shared/energy_policy_white_paper_8.23.pdf

Executive Summary

A crucial component of Mitt Romney’s Plan for a Stronger Middle Class is to dramatically increase domestic energy production and partner closely with Canada and Mexico to achieve North American energy independence by 2020. While President Obama has described his own energy policy as a “hodgepodge,” sent billions of taxpayer dollars to green energy projects run by political cronies, rejected the Keystone XL Pipeline as not in “the national interest,” and sought repeatedly to stall development of America’s domestic resources, Romney’s path forward would establish America as an energy superpower in the 21st century.

“An affordable, reliable supply of energy is crucial to America’s economic future. I have a vision for an America that is an energy superpower, rapidly increasing our own production and partnering with our allies Canada and Mexico to achieve energy independence on this continent. If I am elected president, that vision will become a reality by the end of my second term.”

-Mitt Romney

“We have an unprecedented opportunity to make our natural resources a long-term source of competitive advantage for our nation. If we develop these resources to the fullest, we will not only guarantee ourselves an affordable and reliable supply of energy, but also enjoy benefits throughout our economy. Our trade deficit will shrink, our dollar will strengthen, and tens of billions of dollars will flow to the treasury. Perhaps most importantly, we will experience a manufacturing resurgence that delivers more jobs and more take-home pay for middle-class families across the country.”

-Mitt Romney

THE ROMNEY AGENDA:

• Empower states to control onshore energy development;
• Open offshore areas for energy development;
• Pursue a North American Energy Partnership;
• Ensure accurate assessment of energy resources;
• Restore transparency and fairness to permitting and regulation; and
• Facilitate private-sector-led development of new energy technologies.

The Top American Science Questions: 2012

“Speaking last October, Romney said: ‘My view is that we don't know what is causing climate change on this planet and the idea of spending trillions and trillions of dollars to try and reduce CO2 emissions is not the right course for us.’ Last month, he appeared to backtrack slightly, saying that he believed human activity could be contributing to a warming world in an online debate.”

Candidates' Answers, a Side by Side Comparison

Barack Obama's answers to the Top American Science Questions September 4, 2012

Mitt Romney's answers to the Top American Science Questions September 4, 2012

2. Climate Change. The Earth’s climate is changing and there is concern about the potentially adverse effects of these changes on life on the planet. What is your position on cap-and-trade, carbon taxes, and other policies proposed to address global climate change—and what steps can we take to improve our ability to tackle challenges like climate change that cross national boundaries?
Barack Obama: Climate change is the one of the biggest issues of this generation, and we have to meet this challenge by driving smart policies that lead to greater growth in clean energy generation and result in a range of economic and social benefits. Since taking office I have established historic standards limiting greenhouse gas emissions from our vehicles for the first time in history. My administration has made unprecedented investments in clean energy, proposed the first-ever carbon pollution limits for new fossil-fuel-fired power plants and reduced carbon emissions within the Federal Government. Since I took office, the U.S. is importing an average of 3 million fewer barrels of oil every day, and our dependence on foreign oil is at a 20-year low. We are also showing international leadership on climate change, reaching historic agreements to set emission limits in unison with all major developed and developing nations. There is still more to be done to address this global problem. I will continue efforts to reduce our dependence on oil and lower our greenhouse gas emissions while creating an economy built to last.		Mitt Romney: I am not a scientist myself, but my best assessment of the data is that the world is getting warmer, that human activity contributes to that warming, and that policymakers should therefore consider the risk of negative consequences. However, there remains a lack of scientific consensus on the issue — on the extent of the warming, the extent of the human contribution, and the severity of the risk — and I believe we must support continued debate and investigation within the scientific community. Ultimately, the science is an input to the public policy decision; it does not dictate a particular policy response. President Obama has taken the view that if global warming is occurring, the American response must be to slash carbon dioxide emissions by imposing enormous costs on the U.S. economy. First he tried a massive cap-and-trade bill that would have devastated U.S. industry. When that approach was rejected by Congress, he declared his intention to pursue the same course on his own and proceeded through his EPA to impose rules that will bankrupt the coal industry. Nowhere along the way has the President indicated what actual results his approach would achieve — and with good reason. The reality is that the problem is called Global Warming, not America Warming. China long ago passed America as the leading emitter of greenhouse gases. Developed world emissions have leveled off while developing world emissions continue to grow rapidly, and developing nations have no interest in accepting economic constraints to change that dynamic. In this context, the primary effect of unilateral action by the U.S. to impose costs on its own emissions will be to shift industrial activity overseas to nations whose industrial processes are more emissions-intensive and less environmentally friendly. That result may make environmentalists feel better, but it will not better the environment. So I oppose steps like a carbon tax or a cap-and-trade system that would handicap the American economy and drive manufacturing jobs away, all without actually addressing the underlying problem. Economic growth and technological innovation, not economy-suppressing regulation, is the key to environmental protection in the long run. So I believe we should pursue what I call a “No Regrets” policy — steps that will lead to lower emissions, but that will benefit America regardless of whether the risks of global warming materialize and regardless of whether other nations take effective action. For instance, I support robust government funding for research on efficient, low-emissions technologies that will maintain American leadership in emerging industries. And I believe the federal government must significantly streamline the regulatory framework for the deployment of new energy technologies, including a new wave of investment in nuclear power. These steps will strengthen American industry, reduce greenhouse gas emissions, and produce the economically-attractive technologies that developing nations must have access to if they are to achieve the reductions in their own emissions that will be necessary to address what is a global issue.

6. Energy. Many policymakers and scientists say energy security and sustainability are major problems facing the United States this century. What policies would you support to meet the demand for energy while ensuring an economically and environmentally sustainable future?
Barack Obama: Since taking office, I have supported an all-of-the-above energy approach that will allow us to take control of our energy future, one where we safely and responsibly develop America’s many energy resources – including natural gas, wind, solar, oil, clean coal, and biofuels – while investing in clean energy and increasing fuel efficiency standards to reduce our dependence on foreign oil. I know the country that harnesses the power of clean, renewable energy will lead the global economy in the 21st century. That’s why I have made the largest investment in clean energy and energy efficiency in American history and proposed an ambitious Clean Energy Standard to generate 80 percent of our electricity from clean energy sources like wind, solar, clean coal, and natural gas by 2035. Since taking office, electricity production from wind and solar sources has already more than doubled in the United States. We are boosting our use of cleaner fuels, including increasing the level of ethanol that can be blended into gasoline and implementing a new Renewable Fuel Standard that will save nearly 14 billion gallons of petroleum-based gasoline in 2022. America has regained its position as the world’s leading producer of natural gas. My administration is promoting the safe, responsible development of America’s near 100-year supply of natural gas that will help support more than 600,000 jobs. Because of these actions, we are positioning ourselves to have cleaner and cheaper sources of fuel that make us more energy secure and position the U.S. as a world leader in the clean energy economy.		Mitt Romney: A crucial component of my plan for a stronger middle class is to dramatically increase domestic energy production and partner closely with Canada and Mexico to achieve North American energy independence by 2020. While President Obama has described his own energy policy as a “hodgepodge,” sent billions of taxpayer dollars to green energy projects run by political cronies, rejected the Keystone XL Pipeline as not in “the national interest,” and sought repeatedly to stall development of America’s domestic resources, my path forward would establish America as an energy superpower in the 21st century. The goal of energy independence has long proved elusive, but analysts across the spectrum — energy experts, investment firms, even academics at Harvard University — now recognize that surging U.S. energy production, combined with the resources of America’s neighbors, can meet all of the continent’s energy needs within a decade. The key is to embrace these resources and open access to them. A successful national energy strategy will have a fundamental influence on the well-being of the nation. An expansion in the affordable, reliable supply of domestically produced energy can bolster the competitiveness of virtually every industry within the country, creating millions of new jobs from coast to coast. With fewer energy imports and more exports of manufactured goods, America’s trade deficit will decline and the dollar will strengthen. The benefits even extend beyond immediate economic growth. The lease payments, royalties, and taxes paid to the American people in return for the development of the nation’s resources can yield literally trillions of dollars in new government revenue. Lower energy prices can ease the burdens on household budgets. And all Americans can rest assured that the nation’s security is no longer beholden to unstable but oil-rich regions half way around the world. I have put forward a six-part plan for achieving these goals. First, I will empower states to control onshore energy development, including on federal lands within their borders. Second, I will open offshore areas to development. Third, I will pursue a North American Energy Partnership so that America can benefit from the resources of its neighbors. Fourth, I will ensure accurate assessment of the nation’s energy resources by updating decades-old surveys that do not reflect modern technological capabilities. Fifth, I will restore transparency and fairness to permitting and regulation. And sixth, I will facilitate private-sector-led development of new energy technologies. Throughout this agenda, I remain committed to implementing and enforcing strong environmental protections that ensure all energy development activity is conducted in a safe and responsible manner. But whereas President Obama has used environmental regulation as an excuse to block the development of resources and the construction of infrastructure, I will pursue a course that designs regulation not to stifle energy production but instead to facilitate responsible use of all energy sources — from oil and coal and natural gas, to nuclear and hydropower and biofuels, to wind and solar. Energy development, economic growth, and environmental protection can go hand-in-hand if the government focuses on transparency and fairness instead of seeking to pick winners and repay political favors. A full white paper describing my plan for energy independence is available at MittRomney.com.
7. Food. Thanks to science and technology, the United States has the world's most productive and diverse agricultural sector, yet many Americans are increasingly concerned about the health and safety of our food. The use of hormones, antibiotics and pesticides, as well as animal diseases and even terrorism pose risks. What steps would you take to ensure the health, safety and productivity of America's food supply?
Barack Obama: Since taking office, I have been working to safeguard our food supply, prevent foodborne illnesses and improve consumers’ knowledge about the food they eat. When I started, our food safety system needed to be modernized. One in four people were getting sick every year due to food-borne illness, and children and the elderly were more at risk. I signed the most comprehensive reform of our nation's food safety laws in more than 70 years – giving the Food and Drug Administration the resources, authority and tools needed to make real improvements to our food safety system. We have strengthened standards, prevented food from being contaminated with dangerous bacteria, bolstered surveillance used to detect contamination problems earlier, and responded to illness outbreaks faster. I am also working to bolster the use of organic farming methods and minimize pesticides and antibiotics in our food. I set the ambitious goal to increase the number of certified organic operations by 20 percent – and we expect to meet that target. I am protecting human health by ensuring that the foods the American public eats will be free from unsafe levels of pesticides by making sure that all new, and even older pesticides, comply with strict science-based health standards. We are also making sure safer pesticides get to market faster, so that we can decrease the use of those pesticides that have higher risks of health impacts. And my administration is taking steps to limit antibiotic use for livestock. This will help ensure that antibiotics are used only address diseases and health problems, and not for enhancing growth and other production purposes. And I will continue to work on food safety issues to ensure that public health is the priority in our food safety system.		Mitt Romney: Food safety is crucial to both the health and safety of the American people and the economic strength of the agriculture sector as it serves both this nation and export markets around the world. Businesses and workers in America’s agriculture system, from farmers and ranchers to packager and processors to grocers and restaurants, work incredibly hard to provide peace of mind to the hundreds of millions they feed every year. Government regulators play an important role in this system, monitoring products and processes while taking rapid action when problems do arise. Preventive practices are the best tool to reduce the incidence of food-borne illnesses because they provide the greatest control over the potential risks of contamination and are generally the most cost-effective. These practices are best developed by growers, handlers, processors, and others in the supply chain with specific knowledge of the risks, diversity of operations in the industry, and feasibility of potential mitigation strategies. In a Romney Administration, the FDA will work closely with industry, and collaborate with researchers and state agencies, to develop specific guidance for the commodities most often associated with food-borne illness outbreaks. With advanced research and continued scientific breakthroughs, state-of-the-art monitoring, and a collaborative instead of combative relationship between regulators and businesses, America’s food system will continue to be the world’s best.
8. Fresh Water. Less than one percent of the world’s water is liquid fresh water, and scientific studies suggest that a majority of U.S. and global fresh water is now at risk because of increasing consumption, evaporation and pollution. What steps, if any, should the federal government take to secure clean, abundant fresh water for all Americans?
Barack Obama: I am working to ensure the integrity of the water Americans rely on every day for drinking, swimming and fishing, and that support farming, recreation, tourism and economic growth. My Administration released a national clean water framework aimed at developing a comprehensive approach to protecting the health of America’s waters. Through partnerships with communities around the country, we are working to improve water quality, restore rivers and critical watersheds, and we are making headway in ensuring that our nation’s waters best serve its people. To help with water scarcity concerns in the West and elsewhere, I am supporting water conservation programs. My administration has awarded 92 grants to water conservation projects that will save enough water for an estimated 950,000 people. We are also working collaboratively with communities around the country on how to best manage freshwater resources in a changing climate, in order to ensure adequate water supplies and protect water quality. Having clean water isn’t enough if people don’t have access to it, which is why we are also working to improve access to clean water for rural American’s and border counties. Already, my administration has invested in 5,100 water and waste water community infrastructure projects to safeguard the health of 18 million rural residents and support 135,000 jobs. This past summer, we also streamlined the process to improve water quality along the US-Mexico border that previously didn’t have the right water facilities to ensure clean water. By working together, we can continue to build on these achievements and find more efficient ways to use the water available, conserve where we can, protect jobs, and secure safe drinking water for all Americans today and for years to come.		Mitt Romney: America has made extraordinary environmental progress in recent decades thanks to the laws that protect our air and water. But while these laws have served us well, they have not been modernized in over twenty years and are now significantly out of date. Our communities and businesses must contend with excessively costly and inflexible approaches that impose unnecessary economic constraints and trigger inevitable litigation. The result is to delay progress that could be achieved, and to leave communities and natural resources worse instead of better off. I will modernize the federal laws and regulations governing water use to enable smarter, more collaborative, more flexible, and more cost-effective approaches that welcome state and local participation as partners and leaders. A combination of incentives, market-based programs, and cooperative conservation measures will improve the water quality of our lakes, rivers, streams and coastal environments. Through a renewed focus on research and technology in both the private and public sectors, America can meet the growing challenge of maintaining and improving the nation's drinking water and sanitation infrastructure

10. Ocean Health. Scientists estimate that 75 percent of the world’s fisheries are in serious decline, habitats like coral reefs are threatened, and large areas of ocean and coastlines are polluted. What role should the federal government play domestically and through foreign policy to protect the environmental health and economic vitality of the oceans?
Barack Obama: I am committed to ensuring that our nation’s vast natural resources are used responsibly, and that we maintain healthy oceans and coasts. By establishing a National Ocean Policy, I made it a priority of the federal government to ensure a proactive approach to improving the conservation of the ocean, our coasts, and the Great Lakes. We are directing additional funding to Gulf Coast restoration to bring back the fisheries and coastal ecosystems which are still recovering in the aftermath of the Deepwater Horizon spill. We kicked off the Great Lakes Restoration Initiative, the largest investment in the Great Lakes in two decades, which is targeting ecological problems such as invasive species, toxic hot spots, and pollution runoff. We are cleaning up the Chesapeake Bay, establishing a “pollution diet” for the Bay that will help restore the natural habitat for fish and other wildlife. We have also invested over $1.4 billion in Everglades’ restoration, helping restore tens of thousands of acres which will serve as a sanctuary for native Florida plants and wildlife. We have created or enhanced more than 540 public coastal recreation areas, protected more than 54,000 acres of coastlines and restored over 5,200 acres of coastal habitat. We are also investing more in monitoring our fishing stock in coastal areas so we have the most accurate data possible on the health of our fisheries. These are significant steps that are helping us improve the health of our oceans and build more robust fisheries.		Mitt Romney: The health of the world’s fisheries is of paramount economic and environmental importance to not only America but also the global community. Maintenance of those fisheries also represents a significant regulatory challenge, and is indeed often used as an archetypical illustration of a situation in which a market will not succeed without some form of governance. The question, though, is what form of governance should be employed: where are international agreements required, where is government regulation most appropriate, and where can the fishing industry itself serve as the best steward? The federal government has a vital role to play in conducting sound science and making the resulting data available. Not only federal agencies but also foreign and local governments, regional cooperatives, and industry associations should have access to the data to protect the health and vitality of the oceans and to adjust policy when necessary. A Romney Administration will safeguard the long-term health of fisheries, while welcoming input from the fishermen most affected at every step and seeking to accommodate the needs of these small businessmen wherever possible.

13. Critical Natural Resources. Supply shortages of natural resources affect economic growth, quality of life, and national security; for example China currently produces 97% of rare earth elements needed for advanced electronics. What steps should the federal government take to ensure the quality and availability of critical natural resources?
Barack Obama: Rare earth elements and other critical minerals are used by American manufacturers to make high-tech products like the advanced batteries that power everything from hybrid cars to cell phones. My support for the development alternatives to rare earth materials is helping to ensure we have the materials necessary to propel our high-technology economy forward. Being able to manufacture competitive products in America is too important for us to stand by and do nothing. We've got to take control of our energy future, and we can’t let the energy industry take root in other countries because they are allowed to break the rules. That’s why we have joined with Japan and some of our European allies to bring a trade case against China for imposing restrictions on their exports of rare earth materials. Part of our strategy is also to use the natural resources we have more efficiently, so we are less reliant on other countries in the first place. To achieve that, I have invested in a series of innovative projects to decrease our reliance on rare earth material and unveiled a federal strategy to promote U.S.-based electronics recycling to keep American manufactures competitive. We are also launching a new, multidisciplinary energy innovation research “hub” to advance our leadership in manufacturing products that rely on rare earth materials and other critical materials. The hub -- which will bring together scientists, materials specialists, and others – will aim to develop efficiencies and alternatives that reduce the amount of rare earths that we need as well as develop strategies to ensure that we have a reliable supply of rare earths and other critical materials going forward.		Mitt Romney: The United States was once self-sufficient in its production of critical natural resources like rare-earth minerals. But a decline in production, driven more by regulation than by economics or scarcity, has left the nation reliant on imports. The key to guaranteeing the quality and availability of these resources is a modernized regulatory regime that protects the environment while providing access to the inputs that our economy requires to grow and thrive. Energy provides a good example. Reliance on foreign oil imports has long been seen as an insurmountable challenge but, as noted above, extraordinary technological breakthroughs in the private sector have placed America at the edge of an energy revolution that has the potential to dramatically expand domestic production and achieve energy independence on the continent by the end of the decade. The federal government must open greater access to federal lands, and adopt streamlined regulatory processes that encourage rather than stifle resource development. As the first element of my plan for energy independence, I have proposed giving states authority to manage the development of energy resources within their borders, including on federal lands. States have crafted highly efficient and effective permitting and regulatory programs that address state-specific needs. For instance, while the federal government takes an average of 307 days to permit the drilling of an oil well on federal land, the state of North Dakota can permit a project in ten days. Colorado does it in twenty-seven. Nor do these processes pose any greater environmental risks. To the contrary, from oil and gas and coal to wind and solar and biofuels, states are far better able to develop, adopt, and enforce regulations based on their unique resources, geology, and local concerns. By adopting creative approaches like these to the development of all the nation’s resources, America can benefit fully from its extraordinary natural endowments.

Arctic expert: Final collapse of sea ice imminent

Arctic expert predicts final collapse of sea ice within four years

As sea ice shrinks to record lows, Prof Peter Wadhams warns a 'global disaster' is now unfolding in northern latitudes

One of the world's leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years. In what he calls a "global disaster" now unfolding in northern latitudes as the sea area that freezes and melts each year shrinks to its lowest extent ever recorded, Prof Peter Wadhams of Cambridge University calls for "urgent" consideration of new ideas to reduce global temperatures.

....Wadhams has spent many years collecting ice thickness data from submarines passing below the arctic ocean. He predicted the imminent break-up of sea ice in summer months in 2007, when the previous lowest extent of 4.17 million square kilometres was set. This year, it has unexpectedly plunged a further 500,000 sq km to less than 3.5m sq km. "I have been predicting [the collapse of sea ice in summer months] for many years. The main cause is simply global warming: as the climate has warmed there has been less ice growth during the winter and more ice melt during the summer."

Arctic sea ice at record seasonal minimum

Arctic sea ice extent settles at record seasonal minimum

September 19, 2012

On September 16, 2012 sea ice extent dropped to 3.41 million square kilometers (1.32 million square miles). This appears to have been the lowest extent of the year. In response to the setting sun and falling temperatures, ice extent will now climb through autumn and winter. However, a shift in wind patterns or a period of late season melt could still push the ice extent lower. The minimum extent was reached three days later than the 1979 to 2000 average minimum date of September 13.

This year’s minimum was 760,000 square kilometers (293,000 square miles) below the previous record minimum extent in the satellite record, which occurred on September 18, 2007.  This is an area about the size of the state of Texas. The September 2012 minimum was in turn 3.29 million square kilometers (1.27 million square miles) below the 1979 to 2000 average minimum, representing an area nearly twice the size of the state of Alaska. This year’s minimum is 18% below 2007 and 49% below the 1979 to 2000 average.

Overall there was a loss of 11.83 million square kilometers (4.57 million square miles) of ice since the maximum extent occurred on March 20, 2012, which is the largest summer ice extent loss in the satellite record, more than one million square kilometers greater than in any previous year.

But unlike my opponent, I will not let oil companies write this country's energy plan or endanger our coastlines or collect another $4 billion in corporate welfare from our taxpayers. We're offering a better path.

         We're offering a better path where we — a future where we keep investing in wind and solar and clean coal, where farmers and scientists harness new biofuels to power our cars and trucks, where construction workers build homes and factories that waste less energy, where — where we develop a hundred-year supply of natural gas that's right beneath our feet. If you choose this path, we can cut our oil imports in half by 2020 and support more than 600,000 new jobs in natural gas alone. And yes, my plan will continue to reduce the carbon pollution that is heating our planet, because climate change is not a hoax. More droughts and floods and wildfires are not a joke. They are a threat to our children's future.

Over and over, we've been told by our opponents that bigger tax cuts and fewer regulations are the only way, that since government can't do everything, it should do almost nothing. If you can't afford health insurance, hope that you don't get sick. If a company releases toxic pollution into the air your children breathe, well, that's the price of progress.
