Hundreds of Millions May Soon Be Fleeing the Floodwaters

Mass migration will inevitably be part of human adaptation to climate change, experts agree, since parts of the world will become uninhabitable in the coming decades.

Last year, 38 million people were displaced by climate-related disasters such as the flooding in Pakistan and China.

“Human displacement due to climate change is happening now. There is no need to debate it,” Jonas Gahr Støre, Norway’s minister of foreign affairs, told over 200 delegates attending the Nansen Conference on Climate Change and Displacement in the 21st Century in Oslo Jun. 6-7.

Governments and the humanitarian community need to understand this fact – and that it will get much worse in the coming decades, Støre said.

Without major emissions reductions, climate change could get far worse than anyone is prepared to think about.

“It may be more realistic to consider four degrees C of warming rather than two degrees C,” suggested Harald Dovland, former head of the Norwegian Delegation to the United Nations climate change negotiations.

The world has already warmed 0.8C and will rise to least 1.6 C even if all emissions of carbon and other greenhouse gases ended today, James Hansen, head of NASA’s Goddard Institute for Space Studies, told the conference.

A four-degree C warmer world is a very different planet and risks runaway climate change. Even two degrees C is not safe, Hansen said. 

“The last time the planet was two degrees C warmer was during the Pliocene (five to 2.4 million years ago) and sea levels were 25 metres higher,” he said. “If we burn all the fossil fuels (coal, oil, natural gas) we’re creating conditions that future generations will be unable to cope with.”

Even though a four-degree C warmer world “is choosing the suicidal path”, experts must avoid fuelling xenophobia with predictions of mass migrations and conflicts, says Francois Gemenne, research fellow at the Institute for Sustainable Development and International Relations in Paris.

“This also feeds into a security agenda of panic and paranoia,” Gemenne said.

At least 20 percent of humanity will be at high risk of severe flooding due to sea level rise and extreme rainfall events in the coming decades.

“Too many people live in low-lying deltas and other parts of the world that are becoming too dangerous to live in,” said Gemenne. They will be forced to move and often this movement will be permanent.

Rather than building walls and barriers, countries and the international community need to encourage people to move to safer ground. “Lift the barriers so that people can use migration to adapt to climate change,” he urged delegates.  Continue reading

Arctic Melt Down Is Bringing Harder Winters and Permanently Altering Weather Patterns

Last year’s cold and snowy winter directly connected to warmer Arctic new research reveals

By Stephen Leahy

OSLO, 15 June 2010 (IPS)

Last winter’s big snowfall and cold temperatures in the eastern United States and Europe were likely caused by the loss of Arctic sea ice, researchers concluded at the International Polar Year Oslo Science Conference in Norway in June.

Climate change has warmed the entire Arctic region, melting 2.5 million square kilometres of sea ice, and that, paradoxically, is producing colder and snowier winters for Europe, Asia and parts of North America.

“The exceptional cold and snowy winter of 2009-2010 in Europe, eastern Asia and eastern North America is connected to unique physical processes in the Arctic,” said James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States.

In future, cold and snowy winters will be the rule rather than the exception” in these regions, Overland told IPS.

Scientists have been surprised by the rapid warming of the Arctic, where annual temperatures have increased two to three times faster than the global average. In one part of the Arctic, over the Barents and Karas Seas north of Scandinavia, average annual temperatures are now 10 degrees C higher than they were in 1990.

Overland explains the warming of the Arctic as the result of a combination of climate change, natural variability, loss of sea ice reflectivity, ocean heat storage and changing wind patterns, which has disrupted the stability of the Arctic climate system. In just 30 years, all that extra heat has shrunk the Arctic’s thick blanket of ice by 2.5 million square kilometres – an area equivalent to more than one quarter the size of the continental U.S.

The changes in the Arctic are now irreversible, he said. Continue reading

Science vs Politics at the Edge of the North Pole

SN852510

NY-ÅLESUND, Svalbard, Norway, Jun 14 (IPS)

Spectacular views of mountains and glaciers here in the world’s most northerly permanent human settlement contrasted with business and political leaders’ pessimism and concern about the enormous gap between the action on climate that science deems necessary and what politics considers realistic.

“We must push beyond the politically feasible,” said Tora Aasland, Norway’s minister of research and higher education.

SN852503“Here we are at the edge of the North Pole where climate change is easier to see…How do we communicate the urgency of our situation?” Aasland asked several dozen attendees at a recent high-level symposium in Ny-Ålesund, on the western coast of Spitsbergen Island about 1,200 kilometers from the North Pole.

She emphasised that we already know what to do and how to do it, including reducing fossil fuel energy use, improving energy efficiency, and investing in new technologies like carbon capture and storage.

Taking action on climate is imperative and an ambitious international agreement is urgently needed based on what scientists say is required to stabilise the climate system, participants concluded in a final statement. However, the current series of international climate negotiations in Bonn, Germany have bogged down and are on the edge of collapse, several participants noted. Continue reading
