Has global warming stopped? The tap of incoming energy cannot be turned off
The greenhouse effect caused by CO2 andother GHG gases acts as a “pump”, feeding more and more energy into the Earthsystem. Most of this energy is ultimately stored in the ocean, and the warmingrate of the atmosphere is affected by the air–sea energy transport.

Plugging the ozone hole has indirectly helped Antarctic sea ice to increase
A new study demonstrates that the recovery of the Antarctic Ozone Hole causes decreases in clouds over Southern Hemisphere (SH) high latitudes and increases in clouds over the SH extratropics. The decrease in clouds leads to a reduction in downward infrared radiation, especially in austral autumn. This results in cooling of the Southern Ocean surface and increasing Antarctic sea ice.

Weathering Antarctic storms – weather balloon data boost forecasting skill
Sparse observational data is a problem for predicting Antarctic storms. Researchers show that weather balloon data can help to predict Antarctic storms

Air pollution under clear skies reduces sunlight reaching the Earth’s surface
Scientists have found that the air pollution absorbs and disperses sunlight and thereby reduces the amount that reaches the Earth’s surface. A latest study also reports that the smaller the particles, the more harmful the impacts are.
