Changing Minds about Climate Policy Can Be Done – Sometimes

Simply communicating the benefits is not enough

COLUMBUS, Ohio – Some open-minded people can be swayed to support government intervention on climate change – but only if they are presented with both the benefits and the costs, a new study suggests.

Researchers found that those who were open-minded didn’t change their view if they heard arguments for only one side of the issue.

People who are relatively more closed-minded did not change their mind regardless of the messages they received, or what their original views were. There was also no evidence of open-minded people becoming less supportive of government intervention, no matter if they heard both sides of the argument or only one. (more…)

UCLA life scientists present new insights on climate change and species interactions

UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures. 

“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.”  (more…)

The politics of climate change

U.S. residents who believe in the scientific consensus on global warming are more likely to support government action to curb emissions, regardless of whether they are Republican or Democrat, according to a study led by a Michigan State University sociologist.

However, a political divide remains on the existence of climate change despite the fact that the vast majority of scientists believe it is real, said Aaron M. McCright, associate professor in Lyman Briggs College and the Department of Sociology. (more…)

Recent Antarctic climate, glacier changes at the ‘upper bound’ of normal

In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise.

New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences. (more…)

Where Does Charcoal, or Black Carbon, in Soils Go?

Scientists find surprising new answers in wetlands such as the Everglades

Scientists have uncovered one of nature’s long-kept secrets–the true fate of charcoal in the world’s soils.

The ability to determine the fate of charcoal is critical to knowledge of the global carbon budget, which in turn can help understand and mitigate climate change.

However, until now, researchers only had scientific guesses about what happens to charcoal once it’s incorporated into soil. They believed it stayed there.

Surprisingly, most of these researchers were wrong. (more…)

‘A better path’ toward projecting, planning for rising seas on a warmer Earth

More useful projections of sea level are possible despite substantial uncertainty about the future behavior of massive ice sheets, according to Princeton University researchers.

In two recent papers in the journals Nature Climate Change and the Proceedings of the National Academy of Sciences (PNAS), the researchers present a probabilistic assessment of the Antarctic contribution to 21st-century sea-level change. Their methodology folds observed changes and models of different complexity into unified projections that can be updated with new information. This approach provides a consistent means to integrate the potential contribution of both continental ice sheets — Greenland and Antarctica — into sea-level rise projections. (more…)

Cutting Specific Atmospheric Pollutants Would Slow Sea Level Rise

Decreasing emissions of black carbon, methane and other pollutants makes a difference

With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.

Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.

The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)

Mending the Minnesota

A study of its basin paves the way for cleaner water everywhere

The Minnesota River’s usually placid surface belies its status as a river —and a watershed—in need of help.

The river is naturally prone to heavy sediment loads. It runs through rich glacial deposits, in a channel carved by a catastrophic flood at the end of the last ice age, when a large lake formed by glacial meltwater gave way. (more…)
