The Antarctic Ice Sheet holds enough water to raise the global sea level by more than 57 metres if melted completely. This would flood hundreds of cities worldwide and recent studies show that it is melting fast ....
A new study into how quickly ice sheets melted at the end of the last ice age is raising alarm over how quickly sea levels could rise in today’s warming world. Parts of a large, ancient ice sheet covering Eurasia retreated up 2,000 feet per day — more than the length of the Empire State… ....
The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to waves and warmer temperatures, scientists reported Thursday. ....
Chorisodontium aciphyllum is a hardy terrestrial plant found living in Maritime Antarctica, one of the harshest environments on Earth. Elevated temperatures, stronger winds, and increased ultraviolet-B radiation are some of the conditions that C. aciphyllum is exposed to due to the changing climate. Ultraviolet (UV) radiation-absorbing compounds are produced within this species and so contribute to its resilience. C. aciphyllum grows to form long shoots of moss, therefore these compounds have the potential to serve as environmental proxies as the concentration fluctuations down a shoot may provide information on past climate conditions. This study aimed to begin characterisation of the UV-absorbing compounds of C. aciphyllum sampled from the South Shetland Islands region, Maritime Antarctica, and to examine concentration fluctuations down long shoots. This was achieved by extracting those housed intracellularly and in the cell wall using acidified methanol and alkali based solvents, re ....
Hello, i m christian fraser. you re watching the context on bbc news. five officers charged with murder in the united states, in another notorious case of police brutality. the family of tyre nichols say he was beaten like a pinata. the body cam footage will be released tomorrow. the city of memphis is braced for the backlash. mind the gap. an iceberg the size of greater london breaks free from antartica. we ll go live to the south pole tonight to speak to the scientists monitoring its movement. and with the context tonight, the republican strategist antonia ferrier and anand menon, director of the thinktank, the uk in a changing europe. ....
