What Happens in the Arctic Doesn't Stay in the Arctic

Oak Ridge National Laboratory — Wed, 23 Oct 2024 11:35:33 EST

The Arctic is warming faster than any other area of the planet. How environmental change affects the landscape, weather patterns and infrastructure for communities -- not just here but across the world -- is of keen interest to scientists studying climate change.

Green Leaf Volatiles: A Natural Ally in Plant Stress Resistance

Chinese Academy of Sciences — Wed, 23 Oct 2024 09:55:59 EST

Scientists have identified a natural compound, (Z)-3-hexenyl butyrate (HB), that can induce stomatal closure in plants, a defense mechanism to conserve water and protect against pathogens. This discovery could lead to more sustainable agricultural practices by enhancing crop resilience to environmental stresses without the need for synthetic pesticides.

New Study Reveals Growing Weather Extremes in Indo-Pacific Region Driven by Shifts in Tropical Weather Patterns

National University of Singapore (NUS) — Tue, 08 Oct 2024 06:05:45 EST

A recent study published in Nature Geoscience provides groundbreaking insights into long-term changes in tropical weather patterns that are leading to an increased frequency of extreme weather events such as heatwaves and heavy rainfall in the Indo-Pacific. These changes are possibly driven by global warming, among other factors. The paper, titled "Indo-Pacific regional extremes aggravated by changes in tropical weather patterns", employs a recently proposed methodology that characterises occurrence trends of weather patterns using atmospheric analogues, which are linked to the concept of recurrences in dynamical systems theory.

Unpacking Polar Sea Ice with Math

University of Utah — Fri, 04 Oct 2024 10:05:52 EST

University of Utah mathematics and climate researchers are building new models for understanding the dynamics of sea ice, which is not as solid as you might think. One new study tracks alarming changes in the "marginal ice zone" surrounding the Arctic ice cap.

Impact of Pollutants on Pollinators, and How Neural Circuits Adapt to Temperature Changes

The Kavli Foundation — Fri, 04 Oct 2024 10:05:49 EST

The Kavli Foundation and the U.S. National Science Foundation are collaborating to accelerate research in the emerging field of neurobiology in changing ecosystems. Awardees of the first Kavli-NSF grants will study the impact of atmospheric pollutants on the sense of smell in pollinators, and how neural circuits adapt to changes in temperature.

As Temperatures Rise, Researchers Identify Mechanisms Behind Plant Response to Warming

University of California San Diego — Wed, 02 Oct 2024 16:30:03 EST

Plants widen microscopic pores on their leaves in response to heat. But scientists lacked an understanding of the mechanisms behind this "sweating" function. Now, biologists have unlocked the details behind these processes and identified two paths that plants use to handle rising temperatures.

Extreme Heat Impacts Daily Routines and Travel Patterns

Arizona State University (ASU) — Wed, 02 Oct 2024 07:00:53 EST

Research shows a clear shift in transportation choices under extreme heat conditions. Car use increases, while trips made by walking, biking and public transit drop significantly. On average, public transit trips fall by nearly 50% on extreme heat days as individuals seek relief in air-conditioned private vehicles.
