China's participation in a global climate treaty combined with a global carbon price of $50 per metric ton are necessary to avert catastrophic climate change, according to new research from the Massachusetts Institute of Technology.
How much is a metric ton? About 2,200 pounds.
The International Panel on Climate Change says that if the global temperature rises above 2 degrees Celsius it may result in catastrophic climate change, leading to relentless heatwaves, dangerous sea level rise and more extreme floods and droughts, according to the Bloomberg News article.
The study found that if there is no international policy, temperatures will probably rise by 5.5 Celsius. The $50 dollar figure will likely be needed to keep the rise below 2 Celsius.
In addition to the carbon tax, little if anything will be accomplished without the participation of China, which is the world's biggest user of energy.
Key statements from the actual MIT news release.......
"As the largest greenhouse gas emitter in the world, without China, climate goals - like the 2 degrees Celsius target that most agree is necessary to prevent serious irreversible consequences - are out of reach," says Sergey Paltsev, the lead author of the study and the assistant director for economic research at MIT's Joint Program on the Science and Policy of Global Change.
The researchers stress, however, that reaching that 2 degrees threshold with China's participation is only possible in the most optimistic case. And these days, there isn't much cause for optimism.
Researchers have determined that worldwide glacier loss between 2001-2010 was two to three times more than the corresponding average for the entire 20th century.
A way to reduce the gap between climate models and reality.
What is the scientific method? What does the peer-reviewed process involve?
Greenland's glaciers that flow into the ocean are grounded deeper below the surface of the ocean than previously thought, which could mean an even greater sea level rise than current estimates.
Update on atmospheric CO2, mountain glacier retreat, extreme temperatures and fires.
For the fourth time this year, a new, global record high monthly temperature has been set.
