Calcium-based batteries promise to reach a high energy density at low manufacturing costs. This lab-scale technology has the potential for replacing lithium-ion technology in future energy storage systems. Using the electrolytes available, however, it has been impossible so far to charge calcium batteries at room temperature. Researchers of Karlsruhe Institute of Technology (KIT ) now present a promising electrolyte class, with which this will be possible.

The Olympic marathon and race walking events during Tokyo 2020 Games will be be moved to Japan's northernmost island of Hokkaido from the originally planned Tokyo due to high temperatures, the International Olympic Committee said on Wednesday.

Lebanon has called for international help as it struggles to contain forest fires that have spread across the country since Monday. The death of a volunteer who was assisting firefighters has raised questions about the state’s lack of preparedness despite annual fires at this time of year. High winds and a spike in temperatures have exacerbated forest fires that were particularly devastating in the Chouf region, a mountains area south-east of Beirut famous for its cedars and forest reserves. Dramatic videos shared on Tuesday on social media under the hashtag #Lebanonisburning in Arabic showed high flames threatening villages under an orange sky and the charred remains of pine forests....

Some corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment -- known as rejuvenation -- had only been described in some fossil corals so far. A new study reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón.

Crews battle to contain fires at Busbys Flat and Drake in state’s north as weather warning looms
Firefighters are still working to contain northern New South Wales bushfires before temperatures rise in coming days.
Busbys Flat and Drake fires continued to burn along with several other blazes on Saturday, after a horror week

Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted.

The 70-degree difference in temperatures was one of the largest drops in history
