IPCC Climate Change Report: Experts React. A NASA-funded study finds that the Greenland and Antarctic ice sheets are losing mass at an accelerating pace, three times faster than that of mountain glaciers and ice caps. Here, the Store Glacier, West Greenland. (Credit: Eric Rignot, NASA JPL)
Scientists and other experts all over the world are reacting today (Sept. 27) to the report released by the Intergovernmental Panel on Climate Change (IPCC) stating that scientists are more certain than ever of the link between human activities and global warming.
In the report, climate scientists now say they are at least 95 percent certain that people are responsible for majority of the climate change effects seen since the 1950s, including warming oceans, melting ice and rising sea levels.
Thomas Stocker, co-chair of the report, called climate change "the greatest challenge of our time," and warned that without decisive action to reduce greenhouse gas emissions, many of the impacts of global warming will not only continue, but accelerate.
Today's report is the first of four that will make up the IPCC's Fifth Assessment Report. The remaining parts, which will examine the socioeconomic impacts of climate change and ways to mitigate its effects, will be released in 2014.
