Planting Trees May Not Be as Good for the Climate as Previously Believed

by Moriah McDonald 21 March 202421 March 2024

The climate benefits of trees storing carbon dioxide is partially offset by dark forests’ absorption of more heat from the Sun, and compounds they release that slow the destruction of methane in the atmosphere.

Using Satellite Observations for Attribution of Radiation Changes

by Suzana Camargo 11 March 20248 March 2024

Analysis of infrared satellite measurements identifies the climate response to an increase in greenhouse gases in the atmosphere.

Inland Waters Are a Blind Spot in Greenhouse Gas Emissions

by Saima May Sidik 8 March 202425 June 2024

Researchers call for an extensive monitoring network to quantify carbon dioxide and methane released by China’s rivers, lakes, reservoirs, and ponds.

Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.

The Not-So-Silent Depths

by Gaye Bayrakci and Frauke Klingelhoefer 9 February 202412 February 2024

A new book reveals that ocean depths are far from silent voids, but are actually alive with noise.

Researchers Develop Mexico’s First Comprehensive Greenhouse Gas Budget

Rachel Fritts, Science Writer by Rachel Fritts 8 January 202428 June 2024

A new study delves into 2 decades of data to create a comprehensive quantification of carbon, methane, and nitrous oxide sources and sinks that could help guide climate policy.

“惯性升温”可能触发气候临界点

by Rebecca Owen 30 November 202330 November 2023

除非我们迅速实现净零排放,否则即便在温室气体排放量减少之后,气候也将逐渐接近不可逆转的境地。

Climate Tipping Points Could Be Triggered by “Committed Warming”

by Rebecca Owen 13 November 20231 December 2023

Unless we rapidly reach net zero emissions, the climate will inch closer to a point of no return—even after greenhouse gas emissions are reduced.

Adding Oxygen to a Lake to Explore Methane Emissions

Sarah Stanley, Science Writer by Sarah Stanley 9 November 20239 November 2023

A rare whole-lake experiment suggests that in some cases, low-oxygen conditions may have a smaller impact on methane release to the atmosphere than previously thought.

Rivers Are Warming Up and Losing Oxygen

by Elise Cutts 3 November 20233 November 2023

Researchers used deep learning to fill in the gaps of “patchy” water quality data, revealing decades-long trends toward warmer and less oxygenated rivers that could have worrisome consequences.
