A comprehensive study of tree ring data from the San Joaquin Valley over 600 years indicates that the region has faced more extreme climate variations than those documented in recent history. The research underscores the combined effects of natural variability and human-induced climate change in shaping these extremes, suggesting a potential underestimation of future climate hazards based on current records. Research on 600 years of tree ring data from California’s San Joaquin Valley shows that historic climate extremes…

Recent research indicates that plants could absorb more atmospheric CO2 than previously believed, providing a hopeful perspective on climate change mitigation. However, scientists emphasize the continued importance of reducing emissions, noting that this discovery doesn’t offer a complete solution.A new study reveals that plants might absorb more CO2 than expected, offering hope in combating climate change. However, reducing emissions remains crucial, as planting trees alone isn’t a sufficient solution.New research…

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft in orbit over Earth. The PACE observatory will help us better understand how the ocean and atmosphere exchange carbon dioxide, measure key atmospheric variables associated with air quality and Earth’s climate, and monitor ocean health, in part by studying phytoplankton, tiny plants, and algae that sustain the marine food web.

New research finds that accounting for the long-term impacts of tropical cyclones increases the global Social Cost of Carbon by over 20%. This elevation is driven by projected damage increases in major economies due to global warming. The study emphasizes that current estimates undervalue the real costs of climate change by overlooking these prolonged economic effects.Extreme events like tropical cyclones have immediate impacts, but also long-term implications for societies. A new study published in the journal Nature…

Recent research from the University of Otago indicates that the Antarctic ozone hole has been significantly larger and more persistent than commonly believed, not solely due to CFCs. The study links the hole to changes in the Southern Hemisphere’s climate and weather patterns, despite the Montreal Protocol’s efforts.A new study reveals the Antarctic ozone hole is larger and more enduring than thought, with complex factors beyond CFCs contributing to its persistence and impact on the Southern Hemisphere’s climate.Despite…

A new study by UCL researchers indicates that the Arctic’s rapid warming will lead to the global 2 °C temperature threshold being reached eight years earlier than expected. This finding, which highlights the significant impact of Arctic amplification on global climate targets, calls for increased monitoring and understanding of Arctic temperatures to refine global warming forecasts.New research concludes that the faster warming of the Arctic will expedite the global 2 °C temperature increase by eight years, emphasizing…
