Environment News Service reports: Leading climate scientist and activist James Hansen is warning that the 2 degree Celsius limit to Earth’s temperature rise agreed by world leaders is “highly dangerous.” His new research paper shows that sea levels are rising much more quickly that previously believed.
An adjunct professor in the Department of Earth and Environmental Sciences at Columbia University, Dr. Hansen is lead author of a paper entitled, “Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 °C global warming is highly dangerous” just published in the journal “Atmospheric Chemistry and Physics Discussion.”
The paper is published ahead of the United Nations Climate Summit set for Paris in November and December. There world leaders are expected to agree on a universal, legally-binding agreement to limit the greenhouse gas emissions responsible for global warming.
“Humanity is rapidly extracting and burning fossil fuels without full understanding of the consequences. Current assessments place emphasis on practical eﬀects such as increasing extremes of heat waves, droughts, heavy rainfall, ﬂoods, and encroaching seas,” the authors write. [Continue reading…]
