that's a question i put to dr rachel lowe from the london school of hygiene and tropical medicines. es to suggest some modest associations between temperature and humidity and transmission. a lot of those studies didn't account for confounding factors such as government interventions and social economic differences. and the consensus to date is that the transmission has been very much driven by government interventions and human behaviour, and so we can't base any decisions about relaxing interventions on climate itself. dr lowe says the spread of the virus in warm humid weather in brazil is proof that these conditions aren't significantly hindering it, and weatherfactors can only become more important when there is better global vaccine coverage and immunity, and covid—19 could settle into a seasonal pattern. now, more of the weather that's been making news recently starting with more snow. and this is spain injanuary as the capital, madrid, had its coldest weather in decades with record snowfall measuring more than 50 cm. in february, unusually heavy snow hit greece too, blanketing
