Last year was the second warmest year on record around the globe, making the last decade the warmest in recorded history, according to a new government report released Wednesday.
Scientists from the National Oceanic and Atmospheric Administration and National Aeronautics and Space Administration said the higher average temperatures are the result of human activities that release greenhouse gases and that the trends of warming show that the effects of global warming and climate change are continuing beyond year-to-year fluctuations in temperature and weather.
Experts - NASA - Surface - Temperature - Analysis
Experts from NASA found that average global surface temperature has consistently increased since the 1880s, which their analysis found has been driven by emissions of carbon dioxide and other greenhouse gases produced by human activity such as energy production and transportation.
“We crossed over into more than 2 degrees Fahrenheit warming territory in 2015 and we are unlikely to go back. This shows that what’s happening is persistent, not a fluke due to some weather phenomenon: we know that the long-term trends are being driven by the increasing levels of greenhouse gases in the atmosphere,” said Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies.

In 2019 temperatures around the world were higher -- about 1.8 degrees Fahrenheit or 0.98 degrees Celsius -- than the historical average, according to data from NASA and NOAA. It's the 43rd year in a row that temperatures were above average, the agencies said.
While the rise in temperature may seem small in terms of day-to-day weather, climate experts say even a small amount of warmer average temperatures can change weather patterns and trigger more serious consequences that may not be possible to reverse as the trend continues.

The amount of heat in the ocean was also the highest ever recorded in 2019. The oceans absorb heat and carbon dioxide from the atmosphere which both raises the...
