Here's a statistic: On Earth, 18 of the last 19 years have been the hottest in history.
And as NASA and the National Oceanic and Atmospheric Administration (NOAA) announced on Wednesday, the past five years have been the five warmest in history since the start of quality record keeping in the 1880s. This is an undeniable trend of warming that accelerates.
However, the 21st century global warming is becoming even more alarming compared to the coldest years ever recorded. As climate scientist Simon Donner, who is researching climate change of anthropogenic origin at the University of British Columbia, shows through a list. posted on Twitter, the coldest 20 years on the planet all occurred nearly a century ago, between 1884 and 1929.
The coldest year ever recorded was produced in 1904.
The coldest years of recorded history (since 1880):
1904
1909
1908
1917
1910
1911

1903

The Earth's average temperature has risen more than 1.8 degrees Celsius since the start of the industrial revolution, making annual cold records increasingly rare.
But it is not only the annual cold records that are becoming increasingly rare. In the last 10 years, twice more Daily heat recordings have been defined as cold records.
The score is 21,461 daily highs at 11,466 records.
"In fact, we are seeing an increase in daily heat registers, and we do NOT see an increase in daily cold registers," Michael Mann, a climatologist at Penn State University, told Mashable.
"The trend is exactly in the direction we were expecting as a result of global warming," Mann said.
Although powerful greenhouse gases, including carbon dioxide, retain heat, have been heating the planet for a century, but over the last 40 years, the trend has accelerated and has increased significantly.
"We know since the 1980s that the Earth has a fever," said Sarah Green, an environmental chemist, at Mashable earlier this year.
This is a consequence of simple physics, understood since the 19th century. By the late 1880s, there was simply a lot less carbon dioxide in the air. Now, carbon dioxide levels are probably the highest for 15 million years.
And the Earth responds. Earth is warmer than 120,000 years ago when hippos roamed Europe.
So the cold records, as expected, are disappearing.
