Explaining Extreme Events of 2013

A report released today investigates the causes of a wide variety of extreme weather and climate events from around the world in 2013. Published by the Bulletin of the American Meteorological Society, "Explaining Extreme Events of 2013 from a Climate Perspective (link is external)" addresses the causes of 16 individual extreme events that occurred on four continents in 2013. NOAA scientists served as three of the four lead editors on the report.

Of the five heat waves studied in the report, human-caused climate change was found to have clearly increased the severity and likelihood of those events. On the other hand, for other events examined like droughts, heavy rain events, and storms, fingerprinting the influence of human activity was more challenging. Human influence on these kinds of events—primarily through the burning of fossil fuels—was sometimes evident, but often less clear, suggesting natural factors played a far more dominant role.

"This annual report contributes to a growing field of science which helps communities, businesses and nations alike understand the impacts of natural and human-caused climate change," said Thomas R. Karl, L.H.D., director of NOAA’s National Climatic Data Center. "The science remains challenging, but the environmental intelligence it yields to decision makers is invaluable and the demand is ever-growing."

Confidence in the role of climate change about any one event is increased when multiple groups using independent methods come to similar conclusions. For example, in this report, five independent research teams looked at specific factors related to the record heat in Australia in 2013. Each consistently found that human-caused climate change increased the likelihood and severity of that event. However, for the California drought, which was investigated by three teams from the United States, human factors were found not to have influenced the lack of rainfall. One team found evidence that atmospheric pressure patterns increased due to human causes, but the influence on the California drought remains uncertain.

When human influence for an event cannot be conclusively identified with the scientific tools available today, this means that if there is a human contribution, it cannot be distinguished from natural climate variability.

"There is great scientific value in having multiple studies analyze the same extreme event to determine the underlying factors that may have influenced it," said Stephanie C. Herring, PhD, lead editor for the report at NOAA’s National Climatic Data Center. "Results from this report not only add to our body of knowledge about what drives extreme events, but what the odds are of these events happening again—and to what severity."

The report was edited by Herring, along with Martin P. Hoerling, NOAA’s Earth System Research Laboratory; Thomas Peterson, NOAA’s National Climatic Data Center, and Peter A. Stott, UK Met Office Hadley Centre and written by 92 scientists from 14 countries. View the full report online (link is external).

Planet at Risk

Human interference with the climate system is occurring, and climate change poses risks for human and natural systems . The assessment of impacts, adaptation, and vulnerability in the Working Group II contribution to the IPCC's Fifth Assessment Report (WGII AR5) evaluates how patterns of risks and potential benefits are shifting due to climate change. It considers how impacts and risks related to climate change can be reduced and managed through adaptation and mitigation. The report assesses needs, options, opportunities, constraints, resilience, limits, and other aspects associated with adaptation.

Climate change involves complex interactions and changing likelihoods of diverse impacts. A focus on risk, which is new in this report, supports decision-making in the context of climate change, and complements other elements of the report. People and societies may perceive or rank risks and potential benefits differently, given diverse values and goals.

Compared to past WGII reports, the WGII AR5 assesses a substantially larger knowledge base of relevant scientific, technical, and socioeconomic literature. Increased literature has facilitated comprehensive assessment across a broader set of topics and sectors, with expanded coverage of human systems, adaptation, and the ocean. More

Climate Change Worse Than We Thought, Likely To Be 'Catastrophic Rather Than Simply Dangerous'

Climate change may be far worse than scientists thought, causing global temperatures to rise by at least 4 degrees Celsius by 2100, or about 7.2 degrees Fahrenheit, according to a new study.

The study, published in the journal Nature, takes a fresh look at clouds' effect on the planet, according to a report by The Guardian. The research found that as the planet heats, fewer sunlight-reflecting clouds form, causing temperatures to rise further in an upward spiral.

That number is double what many governments agree is the threshold for dangerous warming. Aside from dramatic environmental shifts like melting sea ice, many of the ills of the modern world -- starvation, poverty, war and disease -- are likely to get worse as the planet warms.

"4C would likely be catastrophic rather than simply dangerous," lead researcher Steven Sherwood told the Guardian. "For example, it would make life difficult, if not impossible, in much of the tropics, and would guarantee the eventual melting of the Greenland ice sheet and some of the Antarctic ice sheet."

Another report released earlier this month said the abrupt changes caused by rapid warming should be cause for concern, as many of climate change's biggest threats are those we aren't ready for.

In September, the Intergovernmental Panel on Climate Change said it was "extremely likely" that human activity was the dominant cause of global warming, or about 95 percent certain -- often the gold standard in scientific accuracy.

"If this isn't an alarm bell, then I don't know what one is. If ever there were an issue that demanded greater cooperation, partnership, and committed diplomacy, this is it," U.S. Secretary of State John Kerry said after the IPCC report was released. More

Business as usual could result in sea level rise of up to seven metres - Club of Rome

Only a complete overhaul of our economic growth and international negotiations can prevent sea level rises that will destroy coastal cities like New York and London experts warn

New York, USA, 28 April: Energy expert Ian Dunlop and policy-planner and scholar Tapio Kanninen delivered a stark message in New York at the end of April that even limiting global warming to 2°C could eventually produce sea level rises of up to 6 to 7 metres (23 feet), wiping out coastal cities like New York, London, Shanghai and Tokyo. They told shocked audiences at the United Nations that if we continue with current policies, temperatures could rise 4°C or more, leading to sea level rises of up to 70 metres (230 feet).

Kanninen and Dunlop were in New York to address a series of packed meetings and panel discussions, organised by the Finnish Mission to the United Nations,Friedrich-Ebert-Stiftung, the Club of Rome, the Temple of Understanding and the UN Department of Economic and Social Affairs.

They presented new evidence demonstrating the severity of the crisis of global sustainability and global survivability and discussed with diplomats, political decision‐makers, sustainable development experts and NGOs how to persuade the UN and other international institutions to take immediate emergency action.

Commenting on recent scientific findings, Ian Dunlop - with over 30 years’ experience at the Royal Shell Group as engineer and senior executive and a former leader of Australia's Emissions trading panel said: “Today’s leadersrefuse to accept that climate change science and the concept of peak oil condemns the international community to a catastrophic future. Why are we stillexploring for fossil fuels, since we can only burn of 20-30% of reserves if we wish to keep climate change to the 2 °C limit, while current policies will result in warming of4-6 °C?” he asked.

This level of temperature rise means that the globe can only carry 0.5-1 billion people, not the present 7 billion, leading experts evaluate.

Tapio Kanninen, a former long time UN staff member and policy-planner, said that scientists have determined a number of "tipping points" that exponentially and dramatically accelerate global warming trends. As they begin to kick in, in a matter of years not decades, we must take action before it is too late to avert a catastrophe.

The severity of the global crisis goes unrecognised: we need a global emergency response and newpolicy models

Dr Kanninen said current international and nationalinstitutional and political systems are incapable of preventing the increasing severe global crises; it requires a change in the entire system plus an emergency response. If runaway climate change leads to rising sea levels the next move has to be to urgently overhaul the UN and our global governance system so it is capable of dealing with rapidly changing global and regional conditions.

Ian Dunlop said that many scientists and practitioners are wrongly dubbed ‘alarmist’, but diplomats, politicians and the whole intergovernmental system have failed to grasp the severity of the crisis. If we fail to act we could find ourselves like a ‘ship of fools’ floating on rising sea levels.

Failing to institute a major global policy change will inevitably lead to the gradual implosion of the economic, ecological and social structures on which we depend, andthey called for “An urgent joint effort by member states, NGOs and scholars to improve the quality of global negotiations on climate change and sustainable development”.

The Club of Rome raised similar issues 40 years ago and recent research has confirmed that its projections ofindustrial collapse in the early 21st century aresurprisingly close to actually data gathered. In his recent book Crisis of Global Sustainability Dr Kanninen evaluates the Club's history and impact, as well as describing the future global crisis if no action is taken.

Setting up new structures

Faced with the reality gap between what scientists predict and what politicians are prepared to do, part of the solution to global inertia lies in creating an independent Global Crisis Network of regional, national and local centres with a global coordination unit that will interact with a revamped UN. Eventually, the UN Charter has to be totally rewritten to correspond to thenew global reality.

The Club of Rome is an international think-tank, based in Switzerland, with 1500 members and over 30 National Associations. Its mission is to undertake forward-looking analysis and assessment on measures for a happier, more resilient, sustainable planet. www.clubofrome.org

The Limits to Growth, a 1972 report to the Club of Rome was written by Denis Meadows, Donella Meadows, Jorgen Randers and William Behrens III. It used computer models to project possible future scenarios with different assumptions of how humans would react to earth’s physical limitations.

Dr Tapio Kanninen is Senior Fellow at the Graduate Center of the City University of New York and a Co-Director of the Project on Sustainable Global Governance. He was Chief of the Policy Planning Unit in the Department of Political Affairs (1998–2005) at the United Nations and worked earlier to set up a global environmental statistical framework in a UNEP-funded project in the UN Statistical Division. He is a member of the Club of Rome.

Ian Dunlop is an Australian Energy Expert, a fellow to the Centre of Policy Development and a former senior executive at the Royal Dutch Shell Group. He is Chair of Safe Climate Australia, Deputy Convenor of the Australian Association for the Study of Peak Oil and a Club of Rome member.

Friedrich-Ebert-Stiftung is a German political foundation with over 100 offices around the world, including an active UN office. It is the Germany's oldest organisation to promote democracy, political education, and promote students of outstanding intellectual abilities.

The Temple of Understanding is an interfaith NGO working to promote global survivability, and an active member of the NGO community working on the inside of the United Nations to advance social justice.

18 FEBRUARY 2013 Food Security in the Age of “Water Grabbing”

Water grabbing or the large-scale, rapid privatization of water is happening worldwide, affecting global food security because local farmers are losing access to both land and water resources.

Gaining control of water is often a motive behind land grabs, and according to a 2013 report published in the Proceedings of the National Academy of Sciences, up to 57 million hectares of land and 454 billion cubic meters of water are grabbed each year. Africa accounts for 47 percent of global grabbed land while Asia accounts for and 33 percent. Both of these continents are home to some of the world’s hungriest people.

According to Citigroup’s chief economist, Willem Buiter, “Water as an asset class will, in my view, become eventually the single most important physical-commodity based asset class, dwarfing oil, copper, agricultural commodities and precious metals.”Companies such as General Electric, Goldman Sachs, Dow Chemical, Talisman Energy, and Coca-Cola have already acquired many land and water resources and are all members of Aqueduct Alliance, a water mapping project that helps investors identify and assess water risks. While this technology can help companies use water resources responsibly, the Institute for Agriculture and Trade Policy notes that it can also contribute to more water grabbing because companies will have greater knowledge of water resources.

When companies grab land and water resources, local farmers have to find ways to still grow enough food to feed themselves and earn a living. Small-scale farmers in sub-Saharan Africa have recently increased their use of affordable, sustainable irrigation techniques to overcome challenges created by water scarcity, but water grabbing may damage this progress. According to a National Geographic article, “the best opportunity in decades for societal advancement in the region will be squandered” if African governments and foreign investors fail to support local farmers’ initiatives in favor of large-scale water deals that mainly benefit corporations.

Extreme Weather

The weekend forecast for Nashville, Tennessee, called for two to four inches of rain. But by the afternoon of Saturday, May 1, 2010, parts of the city had seen more than six inches, and the rain was still coming down in sheets.

Mayor Karl Dean was in the city’s Emergency Communications Center monitoring the first reports of flash flooding when something on a TV screen caught his eye. It was a live shot of cars and trucks on Interstate 24 being swamped by a tributary of the Cumberland River southeast of the city. Floating past them in the slow lane was a 40-foot-long portable building from the Lighthouse Christian School.

“We’ve got a building running into cars,” the TV anchorman was saying.

Dean had been in the “war room” for hours. But when he saw the building floating down the highway, he says, “it became very clear to me what an extreme situation we had on our hands.” Soon 911 calls were coming in from every part of the city. Police, fire, and rescue teams were dispatched in boats. One crew in a skiff headed out to I-24 to pluck the driver of an 18-wheeler from the chest-high water. Other teams pulled families off rooftops and workers from flooded warehouses. Still, 11 people died in the city that weekend.

This was a new kind of storm for Nashville. “It came down harder than I’ve ever seen it rain here,” says Brad Paisley, the country singer, who owns a farm outside town. “You know how when you’re in a mall and it’s coming down in sheets, and you think, I’ll give it five minutes, and when it lets up I’ll run to my car? Well, imagine that it didn’t let up until the next day.”

Over at NewsChannel 5, the local CBS station, meteorologist Charlie Neese could see where the weather was coming from. The jet stream had gotten stuck over the city, and one thunderstorm after another was sucking up warm, humid air from the Gulf of Mexico, rumbling hundreds of miles northeast, and dumping the water on Nashville. While Neese and his colleagues were broadcasting from a second-floor studio, the first-floor newsroom was being swamped by backed-up sewers. “Water was shooting up through the toilets,” Neese says.

The Cumberland River, which winds through the heart of Nashville, started rising Saturday morning. At Ingram Barge Company, David Edgin, a former towboat captain, had more than seven boats and 70 barges out on the waterway. As the rain continued to pound down, he called the U.S. Army Corps of Engineers to get its forecast of how high the river would rise. “It’s blowing up our models,” the duty officer said. “We’ve never seen anything like this.” Edgin ordered all of Ingram’s boats to tie up at safe locations along the riverbank. It turned out to be a smart move.

By Saturday night the Cumberland had risen at least 15 feet, to 35 feet, and the corps was predicting it would crest at 42. But the rain didn’t stop Sunday, and the river didn’t crest until Monday—at 52 feet, 12 feet above flood stage. Spilling into downtown streets, the flood caused some two billion dollars in damage.
