How stable is deep ocean circulation in warmer climate?
If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a new study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.
Under extreme heat and drought, trees hardly benefit from an increased CO2 level
The increase in the CO2 concentration of the atmosphere does not compensate the negative effect of greenhouse gas-induced climate change on trees: The more extreme drought and heat become, the less do trees profit from the increased supply with carbon dioxide in terms of carbon metabolism and water use efficiency. This finding was obtained by researchers of Karlsruhe Institute of Technology (KIT) when studying Aleppo pines. Their study is reported in New Phytologist (DOI: 10.1111/nph.16471).

Bobble-Headed Biden Repeats Debunked Climate Talking Points
Joe Biden’s plan to manage the coronavirus outbreak included a promise to “fight climate change as a driver of health threats” by rejoining the Paris climate treaty on day one of his administration. His proposal went on to state that…
Producing solar power at night
Scientists have developed a new prototype of nighttime solar cells that can produce electricity at night through a radiative cooling mechanism.
Brookhaven Lab’s Lijun Wu receives 2020 Chuck Fiori Award
(DOE/Brookhaven National Laboratory) For the past 20 years, Wu has been advancing quantitative electron diffraction to study batteries, catalysts, and other energy materials.
New model helps explain seasonal variations in urban heat islands
(Duke University) Rising temperatures and shifting rainfall patterns linked to climate change may alter the seasonality of urban heat islands in coming decades. A new model simplifies predictions of ‘urban heat islands’ based on temperature, sunlight and rainfall.
Why approaching comet ATLAS is so bright (and how you can see it)
A newly discovered comet named ATLAS is on track to become one of the brightest comets to grace our night skies since Hale-Bopp in 1997. Officially known as C/2019 Y4, the comet was nicknamed ATLAS in honor of the Asteroid…
