claim: causal empirical estimates suggest covid-19 transmission rates are highly seasonal
evidence_1: moreover, northern hemisphere countries face a crucial window of opportunity: if contagion-containing policy interventions can dramatically reduce covid-19 cases with the aid of the approaching warmer months, it may be possible to avoid a second wave of covid-19 next winter.", "using constructions of expected seasonal temperatures, we project that changing temperatures between march 2020 and july 2020 will cause covid-19 transmission to fall by 43% on average for northern hemisphere countries and to rise by 71% on average for southern hemisphere countries."
