Holocene warming trends in lake sediment analysis, deciphering tropical Australian climates for 10, 400 years.
Credit: Pixabay/CC0 Public Domain Understanding how Earth’s climate naturally fluctuated during the Holocene, a current geological age of 11,700 years, is important to contextualize modern human-driven warming and improve forecasts of future climate. However, the history of tropical Australia’s climate remains unknown, and scientists are often divided into interpretations of the paleoclimate record. To investigate this, a research team led…

SWOT satellites find large river waves for the first time
The SWOT satellite is helping scientists size flood waves in waterways like the Yellowstone River painted in Montana in October 2024. SWOT measures surface water heights, including the oceans, and hundreds of thousands of rivers, lakes and reservoirs in the United States alone. Credit: NP First, researchers at NASA and Virginia Tech used satellite data to measure the height and…

New research links global climate patterns to wildfires in Los Angeles
The cover depicts a serious northern volcano associated with remote tropical convection anomalies via the Madden-Julian vibration (MJO). Visualizes atmospheric Rossby wave propagation, circulating teleconnection, and satellite-derived diagnosis, highlighting remote forcing of intraseasonal variability in mid-latitude fire activity under evolving climatic conditions.

Amazon forest loss leads to measurable reductions in local rainfall
The characteristics of land surface. Credit: AGU Advances (2025). doi:10.1029/2025av001670 The Amazon Basin lost approximately 27,000 square kilometers of forest each year from 2001 to 2016. By 2021, approximately 17% of the basin had been deforested. Changes in forest cover can affect surface albedo, evapotranspiration, and other factors that can alter precipitation patterns. And as the largest tropical forest on…

Krypton-81 method allows for a million years dating of 1kg Antarctic ice samples
Credit: China University of Science and Technology A team led by Professor Zheng Tianlu and Professor Wei Jiang of China Science and Technology (USTC) have developed a new technology known as all optical atom trap trace analysis. In collaboration with American glaciologists, they successfully performed a Crypton-81 date with a kilogram sample of ancient Antarctic ice using this method. This…

Healing ozone holes can help southern oceans take up carbon, research reveals
Credit: Pixabay/CC0 Public Domain New research suggests that the negative effects of ozone holes on carbon uptake in the South Seas are reversible, but only when greenhouse gas emissions drop rapidly. The study, led by the University of East Anglia (UEA), shows that as ozone holes heal, the effects on marine carbon flow in the South Ocean decrease and greenhouse…

Researchers found high levels of mercury in the wetlands of Colorado Mountain
Credit: Pixabay/CC0 Public Domain Climate change flows downstream into local basins by melting glaciers and permafrost in mountains outside Boulder, Colorado, exposing rocks, freeing minerals containing sulfate, a type of sulfur. Researchers at CIRES studied the effects of sulfate in mountain wetlands and confirmed that elevated levels can accumulate food chains and increase potent neurotoxins leading to a wide range…

NASA satellite imagery may provide early volcanic warnings
Chaiten Volcano in southern Chile erupted for the first time in 9,000 on May 2, 2008. NASA satellites that monitor changes in vegetation near the volcano may assist in early eruption warnings. Credits: Jeff Schmaltz, Modis Rapid Response Team, NASA Goddard Space Flight Center Scientists know that changing the leaves of a tree can show that nearby volcanoes can become…

Satellite data from the ship captures the tsunami that first generated a landslide
R/V Sikuliaq is located in the port of Seward, Alaska in May 2022. Credit: Anne Sheehan/Cires Tsunamis generated by landslides pose serious risks to coastal communities, especially within narrow fjords where tall cliffs can trap and amplify waves. Scientists rely heavily on earthquake-based observation systems to issue tsunami warnings, but these methods do not always capture local ground movement caused…

Methane: Where does it come from and why are we running out of time?
Credit: Pixabay/CC0 Public Domain Methane emissions and atmospheric concentrations continue to increase, making it the second most important human-influenced greenhouse gas in terms of post-carbon climate forcing. In fact, methane concentrations have risen faster in the last five years than any period since record-keeping began, but studies suggest that reductions in methane emissions may be cheaper than carbon dioxide mitigation…
