Dustin Schroeder speaks about his research using historic radar film to understand glacier melt in Antarctica.

Marshall Burke explains the economic cost of climate change in the United States.

Marshall Burke speaks about the effect of climate change on flooding.

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

"All the discussions of doom and gloom have not led to change we need," says Rob Jackson.

“They didn’t know what the shape of the continent was, whether it had mountains — this wasn’t about glaciology or studying ice sheets. It was really fundamental Earth exploration,” says Dusty Schroeder.

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 .

Noah Diffenbaugh comments on the potential impact of warm water in the Pacific Ocean.

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.

In a new study, geological sciences PhD student Malcolm Hodgskiss found extreme changes in the atmosphere killed almost 100 percent of life on Earth about 2 billion years ago.

"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.
