Weathering of rocks a poor regulator of global temperatures

Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet’s temperature over millions of years.

Earth’s atmosphere more chemically reactive in cold climates

A study of a Greenland ice core shows that during large climate swings, chemically reactive oxidants shift in a different direction than expected, which means we need to rethink what controls these molecules in our air.

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.

Rapid Arctic warming has in the past shifted Southern Ocean winds

Ice core records from the two poles show that during the last ice age, sharp spikes in Arctic temperatures triggered shifts in the winds around Antarctica.

Large forest die-offs can have effects that ricochet to distant ecosystems

Major forest die-offs due to drought, heat and beetle infestations or deforestation could have consequences far beyond the local landscape. Wiping out an entire forest can have significant effects on global climate patterns and alter vegetation on the other side of the world.

Westerly winds have blown across central Asia for at least 42 million years

Buddhist flags blowing in wind

The winds that gust across the Tibetan Plateau have done so for far longer than previously believed, showing they are resilient to the formation of mountains and changes in carbon dioxide and temperature.

From a tiny island halfway between New Zealand and Antarctica, scientists hope to learn more about the physics of clouds above the stormy, inhospitable Southern Ocean.

A new model explains the fundamental features of the Madden-Julian Oscillation, which some scientists predict will be the “next El Nino.”

With high-tech weather radars, weather balloons, ground instruments and NASA’s DC-8 flying laboratory, scientists will be watching rain and snow storms on Washington’s famously wet Olympic Peninsula.

New research led by the University of Washington and the Pacific Northwest National Laboratory suggests tiny ocean life in vast stretches of the Southern Ocean plays a significant role in generating brighter clouds overhead.

Antarctic ice core shows northern trigger for ice age climate shifts

UW glaciologists were part of a team that used a new Antarctic ice core to discover which region triggered sudden global-scale climate shifts during the last ice age.

Floating sensors built at the UW will be central to a new $21 million effort to learn how the ocean surrounding Antarctica influences climate.

Pine forest particles appear out of thin air, influence climate

Trees in snow

German, Finnish and U.S. scientists have discovered how gas wafting from coniferous trees creates particles that can reflect sunlight or promote formation of clouds.

Global ocean currents explain why Northern Hemisphere is the soggier one

World precipitation map

A new study in Nature Geoscience explains a major feature of global precipitation, and shows how a current originating from the poles influences tropical rainfall in Africa and southern India.
