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.


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.
