July 2019 “has re-written climate history books” as record-breaking heat waves were “seen across the globe,” according to the World Meteorological Organization.

Last Thursday, the World Meteorological Organization estimated that “July 2019 will be around 1.2°C warmer than the pre-industrial era.”

United Nations Secretary-General Antonio Guterres triggered alarms about the ongoing global climate crisis. Guterres released new stats from the Copernicus Climate Change Program–a worldwide weather agency based in Geneva.

Guterres said in a statement to emphasize the alarming issue, “We have always lived through hot summers. But this is not the summer of our youth. This is not your grandfather’s summer.”

The UN chief said that this year’s July was equal, if not hotter than the hottest month recorded in history. By next week, climate experts will be able to determine if the month surpassed all others as the research will have to include the final days of July.

The month of July, the U.N. chief said, at least equaled if not surpassed the hottest month in recorded history. By next week, climate scientists will determine if the month surpassed all others when the final days are included in the research.

The last recorded hottest month of July was three years ago back in 2016. However, it occurred in one of the strongest El Niño phenomena in history. The weather event greatly contributed to the rise in global temperatures at the time. Weather experts fear the worst as record temperatures were reached this year without the aid of an El Niño.
