The World Meteorological Organization announced that July 2019 matched, and broke the record for the hottest month since analysis began.
- The previous warmest month on record was July 2016, and July 2019 was at least on par with it.
- July 2019 was close to 1.2°C above the pre-industrial level.
- Exceptional heat has been observed across the globe in recent weeks, with several European countries recording temperature highs.
- The extraordinary heat was accompanied by dramatic ice melt in Greenland, in the Arctic and on European glaciers.
- Unprecedented wildfires raged in the Arctic devastating the pristine forests which absorb carbon dioxide and turning them into fiery sources of greenhouse gases.
If we do not take action on climate change now, these extreme weather events are just the tip of the iceberg.
