The past decade has been the hottest on record, with greenhouse gases reaching their highest in 2019
REVEALED: The past decade was the HOTTEST on record with greenhouse gases reaching their highest point in 2019 and sea levels now 3.4 inches above what they were in the 1990s
- The 2010s were the hottest decade since record keeping began 150 years ago
- Last year was the second warmest ever, with the most ‘extremely hot days’
- Greenhouse gases peaked in 2019, scientists found, compared to both modern data and ice core samples dating back 800,000 years
- The global sea level is now 3.4 inches above what they were in the 1990s
The past decade has been the hottest on record, according to a new climate change report, with 2019 the second hottest year since record keeping began in the mid-1800s.
Last year’s average temperature on Earth was only surpassed by an erratic warm year in 2016, when a massive El Nino event caused the thermometer to peak.
There was also a record number of ‘extremely hot days’ in 2019, when high temperatures exceeded the 98th percentile in the last 60 years.
The warming trend caused alpine glaciers to lose mass, scientists said, continuing a trend spanning more than 30 years.

According to a report in the Bulletin of the American Meteorological Society, the past 10 years have been the warmest on record, with 2019 the second warmest on record.
Due to the loss of ice in the polar regions, the global sea level is 3.4 inches higher than it was in the 1990s.
And ocean temperatures are also near record highs, second only to 2016.
The study, published in the Bulletin of the American Meteorological Society, found that concentrations of greenhouse gases such as methane and carbon dioxide reached record levels in 2019.
That’s compared to both modern instrumental recordings and ice core samples that are 800,000 years old.
The study, based on data from researchers in more than 60 countries, confirms similar findings from NASA and the National Oceanic and Atmospheric Administration.
And the heatwave is showing no signs of end: From Arizona to Siberia, regions around the world charted record high temperatures in 2020.
In February, the thermometer in Antarctica reached 68F (20.7C) for the first time.
Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, says the rise in temperature is “persistent” and not the result of accidental weather events.
“We crossed into the warming region of over 2 degrees Fahrenheit in 2015 and are unlikely to go back,” Schmidt said.
“We know that the long-term trends are driven by the increasing levels of greenhouse gases in the atmosphere.”
Greenhouse gas concentrations have continued to rise, reaching record levels in 2019. Scientists say that without efforts to curb climate change, the warming trend will only continue.
Chris Rapley, a professor of climate science at University College London, calls global warming one of mankind’s greatest follies.
“This is not so much a record as a broken record,” said Rapley. The message repeats itself with stark regularity, but the pace and scale of action to tackle climate change remains muted and far from necessary.
More than 190 countries signed the Paris climate accords in 2015, which promise to combat global warming and stop the rise in the average global temperature.
Two years later, President Donald Trump announced that the US would withdraw from the agreement.
