“The only downside to a pledge like this is if people misinterpret a pledge to mean action,” says Rob Jackson.

Research by PhD student Malcolm Hodgskiss finds new evidence for a mass extinction event 2.05 billion years ago in barite samples from Hudson Bay, Canada .

Although the safety of it is "actually quite good," Rob Jackson says, “nuclear energy is out of fashion.” 

“This is a well-researched and trustworthy [study] design for understanding the causal effects of changes in things like temperature on economic outcomes,” says Marshall Burke on a new study on the effects of temperature and learning.

"By having this record, we can now see areas where the ice shelf is getting thinnest and could break through," says Dustin Schroeder.

"What this allows us to do is see this change in that ice shelf over, in this case, about 40 years," says Dustin Schroeder.

"Thwaites is one of the fastest-changing, most-potentially unstable glaciers in Antarctica and, as such, understanding it is key for understanding the evolution and potential sea-level contribution of the whole ice sheet," Dustin Schroeder says.

“This is an unnecessary leap backwards,” says Rob Jackson on plans on deregulation of the extraction of oil and natural gas that would lead to more methane emissions.

"No matter the circumstances, moving is hard...One major challenge with retreat is that we’re so focused on getting people out of harm’s way, we miss the chance to help them move to opportunity,”  says Miyuki Hino on managed retreat from areas at risk of flooding. 

“We know there are thresholds we don’t want to cross,” says Chris Field. “But we don’t know precisely where they are.”

Sally Benson and Adam Brandt propose 'macro-energy systems,' a new academic discipline of the science of the energy transition, in a recent paper.

Rob Jackson and César Terrer write about their recently published study showing that plant growth could ameliorate fossil-fuel emissions if forests are protected.

Rob Jackson's recent study is referenced on the ability of plants to absorb the rising levels of atmospheric carbon dioxide in the future.

“In the past, bad weather in one area has been compensated by perhaps better weather in another, but some of our research has shown that as we move toward 2 degrees Celsius of warming, the probability of major cereal producers facing synchronous shocks in the same season goes way up,” says Roz Naylor.

Soil, writes Rob Jackson, “is a no-risk climate solution with big co-benefits. Fostering soil health protects food security and builds resilience to droughts, floods, and urbanization.”

"We ought to recognize that we have profound limits on the amount of land available and we have to be careful about how we utilize it,” Chris Field says about a new United Nations scientific report.
