What you need to know about the 'extreme' heatwave hitting our oceans - video explainer

Scientists have warned a marine heatwave off the coasts of the UK and Ireland poses a serious threat to species. Sea temperatures, particularly off the north-east coast of England and the west of Ireland, are several degrees above normal, breaking records for late spring and early summer. The Met Office has said that according to records dating to 1850, global sea surface temperatures in April and May reached an all-time high, and June is likely to follow suit. A professor of earth sciences, Daniela Schmidt, said 'the extreme and unprecedented temperatures show the power of the combination of human-induced warming and natural climate variability like El Ni?o'. Experts said marine heatwaves have a similar impact on the environment as wildfires on land, destroying organisms that store carbon such as kelp. The damage caused is also harmful to humanity, which relies on oceans for oxygen, storm protection and food.'Unheard of' marine heatwave off UK and Irish coasts poses serious threat Continue reading...
