Temperature of Earth reaches highest level in 115,000 years
A paper entitled “Young People's Burden: Requirement of Negative CO2 Emissions” by James Hansen, a former senior NASA climate scientist, and 11 other experts, claims the global temperature has just reached a level similar to that in the interglacial (Eemian) period, 115,000 to 130,000 years ago, when Earth’s sea level was several meters higher than today.
As a result, glaciers and ice sheets are melting, the oceans are acidifying and rising seas will engulf coastal cities worldwide in the coming centuries.
“The assumption that young [people] will somehow figure out a way to undo the deeds of their forebears has crept into and spread like a cancer through United Nations climate scenarios,” the paper states.
Research shows that the rapid rise of global temperature—beginning in around 1975—continues at a rate of about 0.18°C per decade. The growth rate of climate change, due to human-caused greenhouse gases, increased over 20 percent in the past decade.
The paper states that as global fossil fuels emissions are continuing at a high rate, a burden is being placed on young people to undertake “massive technological CO2 extraction.”
Despite widespread recognition of the risks posed by climate change for decades, Hansen’s paper claims $104 trillion to $570 trillion will be required to combat the problem over the coming century.
The paper was submitted as a discussion paper to the Earth System Dynamics journal.
