Emissions cuts can slash heat deaths in Mideast, N. Africa: study

Meeting world targets to limit climate change would avert hundreds of thousands of heat-related deaths in the Middle East and North Africa, scientists said on Tuesday, urging the region to adapt better.. "Many MENA (Middle East and North Africa) countries also need to strengthen their existing health systems to better prepare for climate change impacts." rlp/gil

NASA reveals crew for 2024 flight around Moon

Scientists in Arctic race to preserve 'ice memory'

Scientists camped in the Arctic are set to start drilling to save samples of ancient ice for analysis before the frozen layers melt away due to climate change, mission organisers said on Monday.. The eight specialists on the mission have set up camp at an altitude of 1,100 metres on the crevasse-ridden Holtedahlfonna ice field and plan to start drilling on Tuesday, Ice Memory said.

Ozone-depleting CFCs hit record despite ban: study

Their power to dissolve the ozone layer shielding Earth from the Sun prompted a worldwide ban, but scientists on Monday revealed that some human-made chlorofluorocarbons have reached record levels, boosting climate-changing emissions.. Despite being banned under the Montreal Protocol, the five chlorofluorocarbons (CFCs) measured increased rapidly in the atmosphere from 2010 to 2020, reaching record-high levels in 2020, according to the study published in the journal Nature Geoscience.
