Air pollution can amplify negative effects of climate change, new study finds

Credit: Unsplash/CC0 Public Domain The impacts of air pollution on human health, farming, and agriculture differ drastically depending on where on the planet the pollutants are emitted, according to a new study that could potentially incentivize certain countries to cut climate-changing emissions. Led by the University of Texas at Austin and the University of California … Read more

Trees can’t outrun climate change. Should humans give them a lift?

Forests’ carbon uptake will be compromised by climate change, leaf temperature study suggests

Forest canopy, HJ Andrews Experimental Forest, Cascade Range, Oregon. Credit: Theresa Hogue, OSU A new study led by Oregon State University suggests leaves in forest canopies are not able to cool themselves below the surrounding air temperature, likely meaning trees’ ability to avoid damaging temperature increases, and to pull carbon from the atmosphere, will be … Read more
