  • Reasons for recommending:
    In the last 20-40 years, extremely hot summers - such as the 2003 heatwave that killed an estimated 30,000 Europeans - have become more frequent in regions across the Northern Hemisphere, Jones et al. point out. Comparing observed Northern Hemisphere temperatures to the predictions of climate models with or without anthropogenic contributions, they conclude that humans have been the dominant cause. Unsurprisingly, the models indicate that we can expect even more scorching summers in the future.
