☄️Early asteroid impacts may have helped create the conditions for life on Earth. A new AGU Advances study suggests asteroid collisions fractured Earth’s crust and fueled long-lasting hydrothermal systems during the planet’s first 1.5 billion years.

Today is the International Day of the Tropics, so we wanted to showcase a recent article that captures how the environment of the tropics impacts our climate. (Image by Paul Brennan from Pixabay)

The Administration's Office of Management and Budget (OMB) released a proposed rule that threatens to reshape how scientific research is funded and conducted in the U.S. We encourage our AGU community to speak up. Act now and submit your comment by 13 July: spklr.io/63320EOZfC

Across 17 million forest patches in the United States, the analysis showed that a hectare within a large continuous forest was 38% more productive on average than an isolated hectare in a similar environment. eos.org/articles/fra...

As wildfires grow more common in the American West, so does the cost of fighting them. A new study projects that spending by the Department of Interior will increase by about 0.65% per year from 2020 to 2100. And USDA Forest Service spending could increase by 0.87% per year. eos.org/research-spo...
