Climate: Support for simple funding plans -- even if costs are high

Mon, 09/21/2020 - 22:13
There is growing demand for countries to take aggressive action to combat climate change, but less consensus on how to fund it. In a new study, researchers asked more than 10,000 people from the US, UK, Germany and France to weigh in. The majority preferred a constant-cost plan - even if costs are high. The finding surprised researchers, but provides valuable insight for policymakers.

How to get a handle on carbon dioxide uptake by plants

Mon, 09/21/2020 - 20:54
How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It's a deceptively complicated question, so a group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.

Studies investigate marine heatwaves, shifting ocean currents

Mon, 09/21/2020 - 17:25
Two new studies investigate marine heatwaves and currents at the edge of the continental shelf, which impact regional ocean circulation and marine life.

Corona-induced CO2 emission reductions are not yet detectable in the atmosphere

Mon, 09/21/2020 - 17:25
The impact of the corona pandemic will reduce worldwide carbon dioxide emissions by up to eight percent in 2020. Cumulative reductions of about this magnitude would be required every year to reach the goals of the Paris Agreement by 2030. Measurements now revealed that concentration of carbon dioxide in the atmosphere has not yet changed due to the estimated emission reductions.

Undersea earthquakes shake up climate science

Sat, 09/19/2020 - 01:50
Sound generated by seismic events on the seabed can be used to determine the temperature of Earth's warming oceans.

Indian monsoon can be predicted better after volcanic eruptions

Fri, 09/18/2020 - 22:45
Large volcanic eruptions can help to forecast the monsoon over India - the seasonal rainfall that is key for the country's agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, a research team now finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El Niño phenomenon after an eruption.

Supercooled water is a stable liquid, scientists show for the first time

Fri, 09/18/2020 - 01:04
First-ever measurements provide evidence that extremely cold supercooled water exists in two distinct structures that co-exist and vary in proportion dependent on temperature.

Curbing land clearing for food production is vital to reverse biodiversity declines

Thu, 09/17/2020 - 20:55
Preserving terrestrial biodiversity requires more ambitious land-conservation targets to be established and met. At the same time, 'bending the curve' on biodiversity loss needs more efficient food production, and healthier and less wasteful consumption and trade. If undertaken with 'unprecedented ambition and coordination,' these efforts provide an opportunity to reverse terrestrial biodiversity loss by 2050.

Wildfire on the rise since 1984 in Northern California's coastal ranges

Thu, 09/17/2020 - 20:55
High-severity wildfires in northern coastal California have been increasing by about 10 percent per decade since 1984, according to a new study.

Emissions could add 15 inches to 2100 sea level rise

Thu, 09/17/2020 - 19:28
An international effort that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions has generated new estimates of how much of an impact Earth's melting ice sheets.

Europe's old-growth forests at risk

Thu, 09/17/2020 - 19:28
A new study presents the first comprehensive assessment of the conservation status of primary forests in Europe -- and shows that many of them are not protected and at risk of being destroyed. The researchers conclude that formal conservation of these forests should be a top priority for countries to meet their climate change and biodiversity goals.

How much will polar ice sheets add to sea level rise?

Thu, 09/17/2020 - 19:28
Over 99% of terrestrial ice is bound up in the ice sheets covering Antarctic and Greenland. Even partial melting of this ice due to climate change will significantly contribute to sea level rise. But how much exactly? For the first time ever, glaciologists, oceanographers, and climatologists from 13 countries have teamed up to make new projections.

Climate change threatens Komodo dragons

Thu, 09/17/2020 - 17:54
The world's largest lizard, the Komodo dragon, could be driven to extinction by climate change unless significant measures to intervene are taken soon.

Saharan dust reaching Amazon quantified

Thu, 09/17/2020 - 17:53
A new study quantified the amount of Saharan dust reaching the Amazon to better understand how dust could impact soil fertility in the region. Intense tropical weathering and local biomass burning have both contributed to nutrient-poor soil in the Amazon Basin.

Sea ice triggered the Little Ice Age

Thu, 09/17/2020 - 17:53
A new study finds a trigger for the Little Ice Age that cooled Europe from the 1300s through mid-1800s, and supports surprising model results suggesting that under the right conditions sudden climate changes can occur spontaneously, without external forcing.

0.5°C of additional warming has a huge effect on global aridity

Thu, 09/17/2020 - 17:53
In a simulation study, researchers showed that limiting global warming to 1.5°C rather than 2°C will mitigate aridification in some regions of the world including the Mediterranean, western Europe, and southern Africa. However, Australia and some parts of Asia were simulated to become wetter rather than drier at both 1.5°C and 2°C of warming. These findings reveal the importance of targeted regional simulations of aridity levels to support policymaking decisions on global warming targets.

New estimates for the rise in sea levels due to ice sheet mass loss under climate change

Thu, 09/17/2020 - 17:53
An international consortium of researchers under the aegis of CMIP6 has calculated new estimates for the melting of Earth's ice sheets due to greenhouse gas emissions and its impact on sea levels, showing that the ice sheets could together contribute more than 40 cm by the end of 2100.

Climate change impacts astronomical observations

Thu, 09/17/2020 - 17:53
Already, climate change is having an impact on the conditions of space observation at the Very Large Telescope in the Atacama Desert. In future, new telescopes will have to be adapted to the expected changes, a new study.

Ocean acidification puts deep-sea coral reefs at risk of collapse

Thu, 09/17/2020 - 17:53
Deep-sea coral reefs face challenges as changes to ocean chemistry triggered by climate change may cause their foundations to become brittle, a study suggests.

Effective pathway to convert CO2 into ethylene

Thu, 09/17/2020 - 15:40
The scientists developed nanoscale copper wires with specially shaped surfaces to catalyze a chemical reaction that reduces greenhouse gas emissions while generating ethylene -- a valuable chemical simultaneously.
