Ice Age manatees may have called Texas home
(University of Texas at Austin) Manatees don’t live year-round in Texas, but these gentle sea cows are known to occasionally visit, swimming in for a ‘summer vacation’ and returning to warmer waters for the winter. New research has found fossil evidence for manatees along the Texas coast dating back to the most recent ice age. The discovery raises questions about whether manatees have been visiting for thousands of years, or if ice age manatees once called Texas home.
How to stop global warming? The most controversial solutions explained – Eco-Business
Depending on who you ask, geoengineering is either a threat to serious climate action, a faraway back-up plan or a necessary part of today’s climate policy. All would likely agree it is contentious. Geoengineering encompasses a broad spectrum of proposed…
Greenland is on track to lose ice faster than in any century over 12,000 years
If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes. Scientists say the results reiterate the need for countries around the world to take action now to reduce emissions, slow the decline of ice sheets, and mitigate sea level rise.
Many ventilation systems may increase risk of COVID-19 exposure, study suggests
Ventilation systems in many modern office buildings, which are designed to keep temperatures comfortable and increase energy efficiency, may increase the risk of exposure to the coronavirus, particularly during the coming winter, according to new research.
Volcanic ash could help reduce CO2 associated with climate change
Scientists investigating ways of removing carbon dioxide (CO2) and other greenhouse gases from our atmosphere believe volcanic ash could play an important role.
Are China’s pollution remediation efforts making the planet warmer?
A 10-year effort by China to improve air quality and reduce pollution-related health risks has caused warming in areas across the northern hemisphere, according to new work.
Lessons from a cooling climate
Usually, talk of carbon sequestration focuses on plants: forests storing carbon in the trunks of massive trees, algae blooming and sinking to the seabed, or perhaps peatlands locking carbon away for tens of thousands of years. While it’s true that plants take up large amounts of carbon from the atmosphere, the rocks themselves mediate a great deal of the carbon cycle over geological timescales. Processes like volcano eruptions, mountain building and erosion are responsible for moving carbon through Earth’s atmosphere, surface and mantle.

EU hydrogen strategy
(European Academies’ Science Advisory Council, Leopoldina – Nationale Akademie der Wissenschaften) Hydrogen is an important alternative for sectors that are stuck in the fossil fuel economy. As national governments and European parliamentarians negotiate the EU’s hydrogen strategy, EASAC issues a new commentary.
Is it one or two species? The case of the cluster anemones
(Università di Bologna) Their scientific name is “Parazoanthus axinellae” and they are among the most fascinating corals of the Mediterranean Sea. A genetic analysis suggests they may belong to two different species and, therefore, there could be two types of cluster anemone. Researchers claim this may lead to more effective conservation strategies against the negative impact of climate change on this sea population
