Global warming is beyond the “point of no return”, according to the lead scientist behind a ground-breaking climate change study.The full impact of climate change has been underestimated because scientists haven’t taken into account a major source of carbon in the environment.
It found that the majority of the Earth’s terrestrial store of carbon was in soil, and that as the atmosphere warms up, increasing amounts are emitted in what is a vicious cycle of “positive feedbacks”.
Guy McPherson has been talking about the positive feedbacks for years. He and others such as Prof Tim Garrett. For those of us paying attention this is yet another concurrence. Use the link above in the quotation section to access the report. Here is the conclusion paragraph from the report:
In conclusion, our global compilation of experimental data allowsus to see past the conflicting results from single-site studies andcapture larger patterns in the sensitivity of soil C to warming. Thewarming-induced changes in soil C stocks reflect the net resultof changes in C fluxes into and from the soil, which can augmentmodelling efforts to project Earth system dynamics into the future.Ultimately, our analysis provides empirical support for the long-held concern that rising temperatures stimulate the loss of soil Cto the atmosphere, driving a positive land C–climate feedback thatcould accelerate planetary warming over the twenty-first century3,4.Reductions in greenhouse gas emissions are essential if we are toavoid the most damaging effects of this feedback over the rest of thecentury.
I disagree. Humans could STOP what they’re doing and make the changes themselves and end the insanity of depending on governments or corporations or financial markets to make the changes. We are the lemmings walking off the cliff.
