The rise will be relatively slow at first, but by 2100 will ramp up sharply. This could happen sooner, warn the scientists, as the impacts of anthropogenic climate disruption (ACD/climate change) continue to intensify.
"This is really happening," Thomas P. Wagner, who runs NASA's programs on polar ice and helped oversee some of the research, said. "There's nothing to stop it now."
On April 13, the world's leading scientific body for the assessment of ACD warned of a "devastating rise of 4-5C if we carry on as we are."
According to Mike Childs, the head of science, policy and research at Friends of the Earth, an increase to 4C warming would mean a "devastating" impact on agriculture and human civilization. Childs added that we would face even more extreme weather events and lose approximately 20-30 percent of the wildlife on the planet. This assessment may even be overly hopeful, given that humans have never lived on a planet at 3.5C or higher.
A report released in April by a joint Australian/US research team states that escalating CO2 emissions now threaten the entire marine food chain, given that more than 90 percent of the excess CO2 in the atmosphere is absorbed by the oceans.
The extreme temperature duality witnessed across the US this past winter is likely to become the norm, thanks to ACD, and it was again revealed who the largest CO2 emitters are. China, the US and India lead as the world's largest polluters.
The rapidity with which ACD is progressing now is truly astounding. Greenhouse gas emissions grew in the first decade of the 21st century at a rate nearly double that of the previous 30 years combined - this, despite the massive economic downturn in 2008.
With full steam ahead for the industrial growth society that dominates the planet, this dispatch reveals another month of dramatic impacts and stunning reports that show, starkly, how humans are disfiguring all facets of the earth."
