Uncovering how grasslands changed our climate

Tue, 01/05/2021 - 15:46
Grasslands are managed worldwide to support livestock production, while remaining natural or semi-natural ones provide critical services that contribute to the wellbeing of both people and the planet. Human activities are however causing grasslands to become a source of greenhouse gas emissions rather than a carbon sink. A new study uncovered how grasslands used by humans have changed our climate over the last centuries.

Reawakened geyser does not foretell Yellowstone volcanic eruptions

Tue, 01/05/2021 - 00:01
Geyser eruptions, like volcanic eruptions, are a mystery, so the reactivation of Steamboat Geyser in Yellowstone in 2018 provided an opportunity to explore why geysers turn off and on, and what determines their periodicity. Researchers found little evidence of magma moving below the geyser, meaning no sign of imminent hydrothermal eruptions, but did discover a relationship between the height of the column and the depth of the water reservoir.

New tool for reconstructing ancient sea ice to study climate change

Mon, 01/04/2021 - 20:19
A previously problematic molecule turns out to be a reliable proxy for reconstructing sea ice, a new study by Brown University researchers shows.

New data-driven global climate model provides projections for urban environments

Mon, 01/04/2021 - 18:41
Cities only occupy about 3% of the Earth's total land surface, but they bear the burden of the human-perceived effects of global climate change, researchers said. Global climate models are set up for big-picture analysis, leaving urban areas poorly represented. In a new study, researchers take a closer look at how climate change affects cities by using data-driven statistical models combined with traditional process-driven physical climate models.

Alert system shows potential for reducing deforestation, mitigating climate change

Mon, 01/04/2021 - 18:40
Forest loss declined 18% in African nations where a new satellite-based program provides free alerts when it detects deforestation activities.

Surprising news: Drylands are not getting drier

Mon, 01/04/2021 - 18:04
A new study shows the importance of long-term soil moisture changes and associated soil moisture-atmosphere feedbacks in future predictions of water availability in drylands. The researchers identified a long-term soil moisture regulation of atmospheric circulation and moisture transport that largely ameliorates the potential decline of future water availability in drylands, beyond that expected in the absence of soil moisture feedbacks.

Pollutants rapidly changing the waters near Ieodo Island

Mon, 01/04/2021 - 16:46
A research team identifies the cause of ocean fertilization in northeast Asian waters.

How to identify heat-stressed corals

Mon, 01/04/2021 - 14:58
Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a new study.

Largest study of Asia's rivers unearths 800 years of paleoclimate patterns

Wed, 12/30/2020 - 16:42
The SUTD study will be crucial for assessing future climatic changes and making more informed water management decisions.

Surveys identify relationship between waves, coastal cliff erosion

Mon, 12/28/2020 - 23:58
Researchers have always known that waves were an important part of the cliff erosion process, but they haven't been able to separate the influence of waves and rain before. After decades of debate over the differing roles that both play, new findings provide an opportunity to improve forecasts.

Carbon capture: Faster, greener way of producing carbon spheres

Mon, 12/28/2020 - 17:18
A fast, green and one-step method for producing porous carbon spheres, which are a vital component for carbon capture technology and for new ways of storing renewable energy, has been developed. The method produces spheres that have good capacity for carbon capture, and it works effectively at a large scale.

Capturing 40 years of climate change for an endangered Montana prairie

Wed, 12/23/2020 - 21:24
Over 40 years of monitoring, an endangered bunchgrass prairie became hotter, drier and more susceptible to fire annually -- but dramatic seasonal changes (not annual climate trends) seem to be driving the biggest changes in plant production, composition, and summer senescence.

Evidence for a massive paleo-tsunami at ancient Tel Dor

Wed, 12/23/2020 - 21:24
Underwater excavation, borehole drilling, and modelling suggests a massive paleo-tsunami struck near the ancient settlement of Tel Dor between 9,910 to 9,290 years ago, according to a new study.

Climate crisis is causing lakes to shrink

Wed, 12/23/2020 - 16:15
Climate change is impacting not only the oceans, but also large inland lakes. As the world's largest lake, the Caspian Sea is a perfect example of how a body of water can and will change. Researchers now discuss the possible ecological, political and economic consequences, as well as viable solutions.

Pandemic and forthcoming stimulus funds could bring climate targets in sight -- or not

Tue, 12/22/2020 - 20:20
The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent. A team of scientists has quantified how different recovery scenarios may affect global emissions and climate change.

New imaging method views soil carbon at near-atomic scales

Tue, 12/22/2020 - 20:19
The Earth's soils contain more than three times the amount of carbon than is found in the atmosphere, but the processes that bind carbon in the soil are still not well understood.

A groggy climate giant: Subsea permafrost is still waking up after 12,000 years

Tue, 12/22/2020 - 15:13
After the Last Glacial Maximum some 14,000 years ago, rising temperature melted glaciers and ice caps worldwide. Over thousands of years, sea levels rose by more than 400 feet (130 meters).

Muddying the waters: Weathering might remove less atmospheric CO2 than thought

Mon, 12/21/2020 - 23:04
The decay of rocks at the Earth's surface may play a lesser role in regulating our climate than previously thought, says new research.

Climate change: Threshold for dangerous warming will likely be crossed between 2027-2042

Mon, 12/21/2020 - 23:04
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 - a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052. Researchers introduce a new and more precise way to project the Earth's temperature. Based on historical data, it considerably reduces uncertainties compared to previous approaches.

Volcanic eruptions directly triggered ocean acidification during Early Cretaceous

Mon, 12/21/2020 - 23:04
New study supports hypothesis that Ontong Java Plateau large igneous province eruptions led to oceanic anoxic event 1a, 127 to 100 million years ago.
