The power of sunlight: Predicting global lake pollution reduction through photochemistry
Global distribution of 3CDOM* concentrations in lakes. Credit: Eco Environment and Health The research investigates how natural photochemical reactions can help break down emerging pollutants in freshwater systems, with a particular focus on clofibric acid and diclofenac. This study focuses on the contrasting effects of triplet sensitization and direct photolysis and provides new insights into how these processes can reduce…

2024 will be the hottest year on Earth as global warming trends continue
Credit: Unsplash/CC0 Public Domain The Earth experienced its warmest year on record in 2024, according to data from the European Union’s Copernicus Climate Change Service, a European-led environmental monitoring program. The service said last year it exceeded the limit of 1.5°C (2.7°F) above the pre-industrial average set by the 2015 Paris Agreement, an international agreement aimed at reducing and reducing…

New global carbon trading market could be held hostage by speculators
Credit: Pixabay on Pexels The future of our planet is in jeopardy as greenhouse gas emissions from burning fossil fuels continue unabated. Treating these emissions as something that can be owned and exchanged on the market has been touted as a solution since the early 1990s, when United Nations negotiations to agree to limits on global warming began. In the…

Global research points to clear solutions to major declines in sharks and rays
Credit: Pixabay/CC0 Public Domain A new global study blames overfishing for the more than 50% decline in shark and ray populations since 1970, but also offers a clear path forward to prevent further declines in their numbers. Professor Colin Simpfendorfer of James Cook University was a co-author of the analysis, published in the journal Science. He said overfishing has shown…

After a disappointing COP29, here’s how to design global climate talks that could actually work
Credit: Pixabay/CC0 Public Domain Many people who have been involved in global climate change negotiations for years see the annual United Nations COP climate negotiations as fundamentally flawed. That includes me. The 29th round of talks concluded on Sunday in Baku, Azerbaijan. It was probably my 25th COP. I have attended these talks in a variety of roles, but primarily…

Humans are already causing long-term global warming of 1.5°C, according to new estimates
Credit: Pixabay/CC0 Public Domain New research published today in Nature Geoscience by Dr Andrew Jarvis of Lancaster University and Professor Piers Forster of the University of Leeds shows that humans have already contributed to global warming of 1.5°C, measured since the period just before the industrial revolution and the 2000s. This indicates that it may be causing the The beginning…

Planting trees in high Arctic latitudes could accelerate rather than slow global warming, scientists say
Direct and indirect effects of afforestation on climate forcing at high latitudes and their relative magnitude over the life of the plantation. a, Plantation establishment disrupts previously intact soils and increases microbial carbon decomposition (1). This is exacerbated by enhanced soil insulation caused by increased snow entrapment and decreased snow cover (2). Growing trees exude carbon from their roots, accelerating…

Computer modeling study reveals history of global ice sheet evolution
Inset map shown on the right. Right: The dark blue region shows the extent of the Laurentide Ice Sheet at 18 ka (modified from Dyke (2009)). The red line indicates the approximate location of the 18 ka “hinge line” in eastern North America that separates modern subsidence and uplift.

Melting Arctic sea ice could affect global ocean circulation, research warns
Melting sea ice can cause temperatures to drop. Credit: Karine Nigar Aarskog / UiT Norwegian Arctic University A warming climate in the polar regions could significantly disrupt ocean circulation patterns, a new study shows. Scientists have discovered that in the distant past, melting Arctic sea ice may have increased the flow of freshwater into the Nordic Seas, significantly impacting ocean…

Global coral bleaching is largest in history: US officials
Coral bleaching, like the one seen around Lizard Island on Australia’s Great Barrier Reef, occurs when water temperatures are too high. A global coral bleaching event that began last year has quickly become the largest in history, with the area of ​​affected coral reefs continuing to expand, according to a U.S. government agency. “About 77% of the world’s coral reef…
