"Last year was the fourth warmest in the modern period, shows the analyses from the u.s. space agency Nasa."
"The global temperature in 2018 was 0.8 degrees Celsius higher than the average of the years 1951-1980, according to the researchers. Only three previous years have had a higher average temperature: in 2015, 2016 and 2017."
"That 2018 is slightly cooler than the last three years is no signal that the warming is on the road to stay up. Overall, the last five years the warmest since measurements began in 1880."
"– We are no longer talking about a situation where global warming is anything in the future. Here it is. It is now, " says Gavin Schmidt, director of the Goddard institute at Nasa, to The New York Times."
"Since 1880, earth's average surface temperature increased by around 1 degree Celsius. The warming is largely due to increased emissions of carbon dioxide and other greenhouse gases in the atmosphere, caused by man, according to Schmidt."
