Last summer was the hottest summer in the Northern Hemisphere in measurement history, the U.S. Federal Weather and Ocean Research Organization (NOAA) says, according to The Guardian.
The average temperature in June-August was 1.17 degrees Celsius
The previous heat records were for 2016 and 2019.
Last August was the second warmest August ever.
According to NOAA, the year 2020 is among the five hottest years in the history of measurement.
The rise in temperature has been linked to extreme events such as wildfires, which are currently affecting, for example, the west coast of the United States.
- Climate change is making heat waves hotter and more common.
Rising temperatures cause drought and fires to occur over a wider area.
And the northern hemisphere has the vast majority of the Earth’s land area and population.
So the worst effects will occur at a time when temperatures in the northern hemisphere are at their highest, CNN meteorologist Brandon Miller opened the link between climate change and extreme events.
Scientists have long warned that the effects of climate change are already visible around the world.
For example, according to a report published in August, both the North and South Poles saw the second hottest year in the history of measurement last year.
The report also covered, for example, record floods in the United States, wildfires in Australia and heat waves in Europe.
- Several extreme phenomena, such as wildfires, heat waves and droughts, are at least partly linked to rising global temperatures.
And, of course, rising temperatures are linked to another climate factor: the increase in greenhouse gases, especially carbon dioxide, nitrous oxide and methane, said climate scientist Robert Dunn, one of the authors of the report.
