Studies of marine shales and isotopic data from the Great Oxidation Event period reveal dynamic oxygen fluctuations in Earth’s early atmosphere and oceans, highlighting the prolonged and complex nature of this critical evolutionary stage. Recent findings indicate that Earth's "Great Oxidation Event" unfolded over a span of 200 million years. Fresh research underscores the intricate nature...
President Joe Biden speaks at an Earth Day event on April 22, 2024 in Triangle, VA. (Photo by Samuel Corum/Sipa USA) The US government is aiming to support carbon offsets by endorsing industry-led efforts to reform a market that has faced increasing criticism. The Biden administration has introduced a set of principles to define “high-integrity” carbon...
(JIJI PRESS/AFP/Japan OUT) Japanese researchers have built the world's first wooden satellite, which is scheduled to be launched on a SpaceX rocket in September. Developed by scientists at Kyoto University and Sumitomo Forestry, this experimental satellite is a tiny cuboid, with each side measuring just 10 centimeters (four inches). The creators anticipate that the wooden material...
Credit: Depositphotos A new study anticipates a worsening global water scarcity scenario, projecting that by 2100, as much as 66% of the population could be impacted, particularly in regions of the Global South. This highlights the urgent necessity to address both the quantity and quality of water in forthcoming water management strategies. Conducted by researchers at Utrecht...

This event, known as A-83, marks the third major iceberg calving in this area in the last four years. In 2021, the first significant event occurred when A-74 separated from the ice sheet, followed by...
LDCs: Extreme temperatures may increase risk of stroke mortality | PreventionWeb Extreme temperatures raise stroke death risk in low-income countries. Both extreme heat and cold are linked to higher death rates from ischemic and hemorrhagic strokes, as found in a new study by Harvard T.H. Chan School of Public Health. The connection between extreme temperatures...
An aerial view of the rust-colored Kutuk River in Gates of the Arctic National Park in Alaska. Thawing permafrost is exposing minerals to weathering, increasing the acidity of the water, which releases metals like iron, zinc and copper For the first time, a large team of North American scientists has mapped Alaska's 'rusting' rivers and...

A research team has compiled findings from 17 real-world climate policies worldwide, offering a more comprehensive understanding than ever before. They employed artificial intelligence to consolidate existing surveys and made them comparable through a new calculation...
This ancient ice block is helping tell the true story of global warmingOSU Although there's increasing evidence suggesting that we're experiencing unparalleled levels of atmospheric greenhouse gases, our limited historical understanding has impeded our ability to contextualize current CO2 emissions over the long term. What if we could utilize the Earth's natural historical records to...
