Animals that migrate north to breed are being put at risk by ongoing climate change and increasing human pressure, losing earlier advantages for migration, declining in numbers and faring much worse than their resident counterparts, according to scientists writing in Trends in Ecology & Evolution.

​The production of renewable energy is increasing every year. But after analysing the growth rates of wind and solar power in 60 countries, researchers at Chalmers, Lund University and Central European University in Vienna, Austria conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. 

Ocean warming caused by anthropogenic greenhouse-​gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival.

Talking in the latest of 10 videos from leading Oxford experts in the run up to the COP26 climate conference, Professor Jebb points out that agriculture accounts for more CO2 emissions than transportation, and she says ‘It is the single biggest cause of harm to nature.’

International research led by Luke Grant, Inne Vanderkelen and Prof Wim Thiery of the VUB research group BCLIMATE shows that global changes in lake temperature and ice cover are not due to natural climate variability and can only be explained by massive greenhouse gas emissions since the Industrial Revolution. 

Scott T. Salesky, an assistant professor of meteorology at the University of Oklahoma, is the principal investigator of a recently awarded $530,297 grant through the National Science Foundation’s Office of Polar Programs to study how katabatic winds – cold, dense winds flowing down a sloping surface – impact snow transport and ultimately contribute to the growth of the Antarctic ice sheet.

The study, led by researchers at the University of Surrey’s Global Centre for Clean Air Research (GCARE), put an extensive array of instruments in and around a hedge to measure the presence of various pollutants at numerous locations, identifying the effect of the hedge at different heights and distances from the road.

For the second consecutive year, Kenya’s semi-arid north has experienced meager rainfall, causing a drought that threatens the food supply of 2.4 million people, according to the United Nations World Food Program, Reuters reported.

Hydropower is the dominant source of energy in the Amazon region, the world’s largest river basin and a hotspot for future hydropower development. 

Research has shed new light on the impact of humans on islands’ biodiversity.
