Så begynder vi så småt at se nogle af resultaterne fra Det Internationale Polarår (IPY).
The International Polar Year effort, spearheaded by WMO and the International Council for Science, is credited with vastly expanding our understanding of the extremes of Earth.
Two years of intense polar research have shown declining snow and ice pack and rising seas.....Among other findings, researchers say they now have conclusive proof that the ice mass found on Antarctica and Greenland is diminishing, contributing to a worldwide rise in sea levels. The Arctic ice cap also shrunk to its smallest size over the summers of 2007 and 2008 since satellite record-keeping began.
Scientists also say that Arctic permafrost is melting, a worrying sign for officials committed to combating climate change. Results of polar research released just last week show that the average temperature of permafrost found in northern Russia has increased by 1 to 2 degrees Celsius over the past 35 years. The findings match an earlier study of Alaskan permafrost that discovered a temperature rise of about 0.5 to 2 degrees Celsius.
The vast swath of permafrost covering the Arctic Circle is known to hold massive quantities of organic material trapped beneath the permanently frozen ground. Scientists suspect that thawing permafrost will lead to much of this material decaying, releasing an enormous amount of carbon dioxide into the atmosphere and exacerbating the greenhouse effect.
Perhaps the biggest finding to come out of the International Polar Year, or IPY, initiative is the discovery that changes to Earth's climate and environment are happening much more rapidly than scientists working on the groundbreaking studies of the Intergovernmental Panel on Climate Change initially suspected
WMO said: "IPY has provided a critical boost to polar research during a time in which the global environment is changing faster than ever in human history. Warming in the Antarctic is much more widespread than it was thought prior to IPY, and it now appears that the rate of ice loss from Greenland is increasing." Fed skrift min

Endnu mere propaganda fra klimaforskningens verdensomspændende sammensværgelse skabt til at skræmme verden? Eller har verden et problem?
