“While climate change may not yet have had its huge impact on biodiversity, just wait,” says Harvard professor Daniel Schrag. “What’s coming is really extraordinary.”
“We’re likely to see 4 maybe even 6 degrees (Celsius) of (global) warming over the next 100 years,” says Schrag, “and it’s happening more than 100 times faster than climate change we’ve experienced in the past.” Schrag believes there might be even more to be concerned about, saying there might be additional factors worsening climate change that scientists have not anticipated.
Adding to his grim forecast, Schrag says reversing the trend will be neither easy nor quick. For one thing, more than half of the CO2 currently affecting climate change will remain in our atmosphere 1,000 years from now. “A silver-bullet solution is not around the corner. It will require innovative investments sustained for at least the next century,” he says.
Schrag says public policy energy choices made “over the next decade or two will have profound effects on the Earth’s system, on every living thing on the planet.” Schrag says determined and sustained energy choices that reduce CO2 emissions are urgently needed to prevent his doomsday prophecies from becoming realities of biblical proportions.
