Ice Age Testing Reveals Challenges in Climate Model Sensitivity
Increased reflection of incoming sunlight by clouds led one current-generation climate model to predict unrealistically cold temperatures during the last ice age.
Tracing the Moisture That Nourishes the World’s Highest Glacier
Using data from weather stations on and around Mount Everest, scientists find that the Khumbu Glacier receives most of its moisture from the Bay of Bengal.
Coastal Brazil Is Likely to Face More Heat Waves and Droughts
In 2014, São Paulo experienced its greatest water crisis ever, caused by an intense drought. New research indicates that it is likely to happen again and be even more severe.
Will Rising Temperatures Make Rice Too Toxic?
Greenhouse experiments reveal how higher temperatures act to elevate arsenic levels in rice and may help focus efforts to solve a crisis threatening food systems around the world.
Airless Exoplanet’s Mantle Could Flow in Halves
With no atmosphere in the way, measurements of the planet’s surface temperature are the first observational constraints on mantle convection models for an exoplanet.
New Insights into Uncertainties About Earth’s Rising Temperature
A comparison of climate models finds that much of the variation in their predictions of global warming arises from differences in how they simulate the response of convective processes to warming.
Capturing Heat-Driven Atmospheric Tides on Mars
Spacecraft observations and model simulations provide new insights into tidal patterns that transport momentum and energy into the planet’s upper atmosphere.
A Clearer Look at Lunar Surface Hydration
Independent ground-based observations of the Moon confirm prior spacecraft observations that hydration at the lunar surface varies with temperature.
Regional Sensitivities Strongly Affect Modeled Climate Extremes
Analysis of temperature and precipitation extremes in two generations of CMIP climate models revealed similarities in regional climate sensitivities, contrasting with divergent global sensitivities.
