Climate change is a global phenomenon. Its impact on economic growth must therefore be analyzed in accordance with its (time-varying) common effects. We present an econometric analysis that evaluates this effect taking into account its global nature. Contrary to previous evidence that ignores the global effects, we obtain that the rising temperature has not decreased growth in real GDP per capita in the second half of the twentieth century for the world countries. However, we obtain a negative effect of rising temperatures and a positive effect of rising precipitation in poor countries. This positive effect of rising precipitation is also confirmed for hot and temperate countries.
气候变化是一个全球性现象。因此，必须根据其（时变的）普遍影响来分析其对经济增长的影响。我们提出了一个计量经济学分析，考虑到其全球性，评估了这种影响。与之前忽略全球效应的证据相反，我们发现，在 20 世纪后半叶，全球各国的气温上升并没有降低实际人均 GDP 的增长。然而，我们发现，在贫穷国家，气温上升的负面影响被降水增加的正面影响所抵消。降水增加的这种正面影响在炎热和温和国家也得到了证实。
