Gender assumptions harm progress on climate adaption and resilience
Scientists say outdated assumptions around gender continue to hinder effective and fair policymaking and action for climate mitigation and adaptation.

The authors said progressing gender equality means breaking down stereotypes and prejudices about gender -- creating environments to enable all people to exercise their agency to cope, change and adapt.

Want to cut emissions that cause climate change? Tax carbon
Putting a price on producing carbon is the cheapest, most efficient policy change legislators can make to reduce emissions that cause climate change, new research suggests.

"If the goal is reducing carbon dioxide in the atmosphere, what we found is that putting a price on carbon and then letting suppliers and consumers make their production and consumption choices accordingly is much more effective than other policies," said Ramteen Sioshansi, senior author of the study and an integrated systems engineering professor at The Ohio State University.

Will climate change outpace species adaptation?
Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.

The researchers found that first and foremost, a species' thermal tolerance is linked to the current climate where they live. "It's logical that thermal limits mostly match a species' present-day climate but tracing the evolutionary history of thermal limits can reveal how species got to be where they are today," says Sunday, an Assistant Professor in the Department of Biology.

The researchers also found that tolerance to cold has evolved much faster than tolerance to heat, particularly in endotherms as compared to ectotherms and plants. Endothermic animals are those that generate metabolic heat to regulate their own body temperature -- for example, mammals and birds -- while ectothermic animals are those that regulate their body temperature using external heat sources, like reptiles, fishes and invertebrates.

Butterflies are vanishing out West. Scientists say climate change is to blame.
The loss of butterflies across Western forests and prairies, like the similar drop in bumblebees nationwide due to rising temperatures, is troubling because both insects play a key role in pollinating crops and wildflowers. And the findings may add to fears among researchers of a broader die-off of insects that could be underway everywhere from Germany to Puerto Rico and beyond — a potential and debated bugpocalypse that threatens to upend ecosystems across the world.

Field study shows icing can cost wind turbines up to 80% of power production
Researchers took their studies of wind-turbine icing out of the lab and into the field to learn how and where ice accumulates on rotating blades. They learned ice on the blades can reduce power production by up to 80%. The field experiments also validated their experimental findings, theories and predictions.

Wind turbine blades spinning through cold, wet conditions can collect ice nearly a foot thick on the yard-wide tips of their blades.

That disrupts blade aerodynamics. That disrupts the balance of the entire turbine. And that can disrupt energy production by up to 80 percent,
according to a recently published field study led by Hui Hu, Iowa State University's Martin C. Jischke Professor in Aerospace Engineering and director of the university's Aircraft Icing Physics and Anti-/De-icing Technology Laboratory.

Apparent Atlantic warming cycle likely an artifact of climate forcing
Volcanic eruptions, not natural variability, were the cause of an apparent 'Atlantic Multidecadal Oscillation,' a purported cycle of warming thought to have occurred on a timescale of 40 to 60 years during the pre-industrial era, according to a team of climate scientists who looked at a large array of climate modeling experiments.

The result complements the team's previous finding that what had looked like an "AMO" occurring during the period since industrialization is instead the result of a competition between steady human-caused warming from greenhouse gases and cooling from more time-variable industrial sulphur pollution.

Climate change, periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.

Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
