Latest IPCC Third Assessment Report Stories
The Sustainable Consumption Institute research claims food which families now take for granted, such as meat and fresh vegetables, could become too expensive for many if global temperatures rise in line with the current trends and reach 4°C within the lifetime of many people.
The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions.
The sea level of the US West Coast is expected to increase 60 centimeters from Washington to northern California, while waters surrounding the southern half of that state could rise a meter in less than two decades time.
For the first time, researchers have been able to combine different climate models using spatial statistics - to project future seasonal temperature changes in regions across North America.
The Intergovernmental Panel on Climate Change (IPCC) reports in their Special Report on Extremes (SREX) that poorer nations with high concentrations of populations are the most at risk in suffering in extreme weather disasters.
Even if zero emissions of greenhouse gases were to be achieved, the world’s temperature would continue to rise by about a quarter of a degree over a decade.
By 2100, global climate change will modify plant communities covering almost half of Earth's land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another.
Scientists have developed important new insight into the sensitivity of global temperature to changes in the Earth’s radiation balance over the last half million years.
