BYE BYE, BABY
Rising temperatures due to climate change are leading to a decline in birth rates, a team at UCLA has found. After trawling through 80 years’ of US birth rate data looking for trends, they found that periods of hot weather seemed to have a negative impact on the number of children born nine months later. It is thought that the effect is due to sperm production falling as temperatures soar.
BREAKING THE ICE
A 6.4km-long iceberg has been filmed breaking away from a glacier in eastern Greenland. Researchers from New York University captured the event during a trip in June. Melting ice is a concern – if the entire Western Antarctic Ice Sheet were to melt, it would result in a three-metre sea level rise, which is enough to cause serious flooding in many coastal areas.
