Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier’s motion over the long term.

Climate change projected to boost insect activity and crop loss, researchers say

Image of ears of wheat

In a paper published Aug. 31 in the journal Science, a team led by scientists at the University of Washington reports that insect activity in today’s temperate, crop-growing regions will rise along with temperatures. Researchers project that this activity, in turn, will boost worldwide losses of rice, corn and wheat by 10-25 percent for each degree Celsius that global mean surface temperatures rise.

Meticulously tracking of 423 species before, during and after the worst droughts to hit California in more than a thousand years shows surprising patterns. Key prey species plummeted in the third year of the drought, and carnivores were hardest hit in later years.

Atlantic Ocean circulation is not collapsing – but as it shifts gears, global warming will reaccelerate

Depiction of Atlantic circulation with red arrows pointing north and blue arrows pointing south.

New research suggests the Atlantic Ocean is transitioning back to its slower phase, which means average global air temperatures will go back to rising more quickly.

Warmer climate will dramatically increase the volatility of global corn crops

corn field in sunshine

A study of global maize production in 2100 shows dramatic increases in the variability of corn yields from one year to the next under climate change, making simultaneous low yields across multiple high-producing regions more likely, which could lead to price hikes and global shortages.

UW faculty selected as authors, editors of international report on climate change

About twice each decade, the United Nations’ Intergovernmental Panel on Climate Change, or IPCC, looks at what is known about the science of climate change, the extent to which human activities are changing the Earth’s climate, and what risks these changes pose to human and natural systems. Organized into three working groups, each assessment is…

With climate change, Mount Rainier floral communities could ‘reassemble’ with new species relationships, interactions

Wildflowers growing on a mountain.

An unseasonably warm, dry summer on Mount Rainier in 2015 caused subalpine wildflowers to change their bloom times and form ‘reassembled’ communities, with unknown consequences for species interactions among wildflowers, pollinators and other animals.

Models, observations not so far apart on planet’s response to greenhouse gas emissions

New analysis debunks reports that recent observations are showing that Earth’s temperature responds less to greenhouse gases than predicted by climate models.


Retreating Yukon glacier caused a river to disappear

A new study provides a postmortem on the Yukon’s Slims River, whose flow was diverted in early 2016. It is the only documented case of “river piracy” in modern times.

Hidden lakes drain below West Antarctica’s Thwaites Glacier

topography of lakes

Drainage of four interconnected lakes below Thwaites Glacier in late 2013 caused only a 10 percent increase in the glacier’s speed. The glacier’s recent speedup is therefore not due to changes in meltwater flow along its underside.

Plants’ future water use affects long-term drought estimates

farmers in field

Many popular long-term drought estimates ignore the fact that plants will be less thirsty as carbon dioxide goes up. Plants’ lower water use could roughly halve some current estimates for the extent of future drought, especially in central Africa and temperate Asia.

white dots on blue background

Polar oceans pump organic carbon down to the deep sea about five times as efficiently as subtropical waters, because they can support larger, heavier organisms. The finding helps explain how the oceans may function under climate change.

Mussels

Scientists from the University of Washington have found evidence that ocean acidification caused by carbon emissions can prevent mussels attaching themselves to rocks and other substrates, making them easy targets for predators and threatening the mussel farming industry.

Trees either hunker down or press on in a drying and warming western U.S. climate

Trembling aspen.

Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.
