Ocean acidification could devastate coral reefs even if atmospheric carbon dioxide stabilizes at 450 ppm. Computer simulations suggest that only a small fraction of existing coral reefs would remain in waters with the kind of chemistry that has sustained them in the past.
Researchers discovered an extreme cooling event 12,700 years ago in Western Europe, with sediments revealing a short-term shift in atmospheric circulation. The findings suggest the climate system is not fully understood, with many puzzles remaining to be solved.
A new study published in Environmental Research Letters finds no correlation between cosmic rays and cloud cover, contradicting a 2007 TV program that suggested global warming is caused by a decrease in cosmic rays. The researchers from Lancaster and Durham Universities analyzed data and found no reliable connection between the two.
A new study reveals that climate change led to habitat loss in mammoth territory, pushing the species towards extinction. Human hunting acted as the final straw, with scientists estimating that humans would only need to kill one mammoth every three years to push the species to extinction.
Global climate models project significant changes in water availability due to anthropogenic warming, with regions like high latitudes and Mediterranean basin expected to experience substantial decreases. Non-stationarity must be accounted for in water resources planning to ensure effective management.
The Intergovernmental Panel on Climate Change (IPCC) and Al Gore were awarded the Nobel Peace Prize in 2007 for their work on man-made climate change. The IPCC's scientific reports have created an informed consensus about human activities' impact on global warming.
Eight Berkeley Lab scientists contributed to the IPCC's working group reports on global climate change, which won the 2007 Nobel Peace Prize. The researchers' efforts have helped build greater knowledge about man-made climate change and its impact, enabling measures to counteract such change.
The IPCC's 4th United Nations Climate Report revealed new facts on global climate change, raising awareness of the issue. The report also highlighted the impact of rising temperatures and species extinction, supported by over 3100 scientific studies.
Researchers at Argonne National Laboratory explore opportunities to increase solar energy conversion as an alternative to fossil fuels, with potential applications in electricity, fuel, and heat generation. Key findings include advancements in materials science, artificial photosynthesis, and thermoelectric materials that could enhance...
The University of Alaska Fairbanks study proposes four policy strategies to sustain people and the environment in a dramatically warming climate. The first strategy focuses on adaptability, while the second emphasizes biological diversity as a buffer from change.
A study found a 3.5% slowdown in the Walker circulation, which drives trade winds and ocean currents. This could lead to a decrease in wind-forced ocean flow by up to 20% by 2100, impacting marine life and fishing regions.
Climate change is already affecting human health, with increased duration of heatwaves in various regions and potential impacts on infectious diseases. Additionally, global warming may lead to regional food yields and water supplies, compromising health outcomes.
A peer-reviewed study published in Science finds a complex warming signal in world oceans over the past 40 years. The signal is of human origin and cannot be explained by natural variability or solar/volcanic forcing.
A Bonn study calculates that greenhouse gases are responsible for just under half of global warming since 1880, with natural factors accounting for the remaining half. The researchers used 30 different climate models to reach this conclusion, which they believe will continue to worsen even after the Kyoto Protocol is implemented.
Researchers predict a decrease in solar activity's impact on global warming over the next 100 years, with potential returns to current levels by 2200. The study suggests that solar variability will not amplify climate change, but rather subdue its effects.
A new study challenges current climate change understanding by suggesting that aerosols may have a greater cooling effect than previously thought. This could alter projections of future climate change if high-magnitude negative aerosol forcing values are correct, potentially downplaying human activity's role in warming.
A new NASA-funded study reveals that human-caused land-use changes significantly contribute to climate change, potentially more so than greenhouse gas emissions. The research proposes a method for comparing different climate change factors, highlighting the importance of land surface changes in redistributing heat and affecting regiona...
Researchers measured aerosols in clean marine conditions and under polluted conditions, revealing large concentrations of particulate material including mineral dust. The findings will help reduce uncertainties in global climate models and develop better policies.
