Extreme ice melt observed at Greenland's summit
The Greenland Ice Sheet is melting at an unprecedented rate as temperatures at Greenland’s summit reach the highest ever observed.
This week, scientists recorded temperatures above 0°C at Greenland’s summit. This is only the third time temperatures have been recorded above freezing, but the second time this summer. These unusually high temperatures are accelerating ice loss from Greenland's Ice Sheet, which covers 80% of the island.
Why are we having a heatwave?
The UK’s soaring temperatures are associated with an area of high pressure, called a blocking anticyclone, which has been building up over Europe during the past week.
Extended periods of hot weather are not uncommon, but research also shows that climate change is making heatwaves more likely.
Using weather radar to monitor insect decline around the world
Scientists are developing a pioneering technique that allows them to monitor insects in the air using weather radars, as part of a research project called BioDAR.
Ecosystems rely on insects for pollination and as vital parts of food webs, but insect populations have been falling sharply. Until now there has been no consistent method for effectively tracking the abundance and diversity of insects over large areas.
BioDAR researchers from the University of Leeds, University of Exeter and the National Centre for Atmospheric Science will use weather radar technology to provide detailed maps of insect abundance and diversity.
Scientists fly over the Atlantic to measure ship exhaust emissions
Scientists on board the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft have started measuring emissions from ship exhausts off the northwest coast of Portugal.
Scientists are collecting measurements to help quantify the impact of upcoming emission regulations, which limit maximum ship sulphur emissions in international waters.
