Change is technologically possible, but there is a 'tricky part'

Prof David Archer.

David Archer believes it is technologically possible to avoid dangerous climate change.

However, the Professor of Geological Sciences at the University of Chicago admits there is a “tricky part” – making the decision.

Writing in his 2008 book, “The Long Thaw: How humans are changing the next 100,000 years of earth’sclimate” Prof Archer says: “Climate change is a global issue that ramps up slowly and last for a long time.

“Negotiating a solution would require a degree of global cooperation that is, I think, unprecedented in human history,” he writes.

The world presently suffers from a malaise of schoolyard-like squabbles between and within nations over myriad of matters that have little or nothing to do with the mitigation of climate change, indicating that the cooperation Prof Archer alludes to will forever elude the human community.

Professor Archer has been a professor in the Department of The Geophysical Sciences at the University of Chicago since 1993. He have worked on a wide range of topics concerning to the global carbon cycle and its relation to global climate, with special focus on ocean sedimentary processes such as CaCO₃ dissolution and methane hydrate formation, and their impact on the evolution of atmospheric CO₂.

He teaches classes on global warming, environmental chemistry, and global geochemical cycles.
