Global warming fueled record temperatures in 2016

... The latest international climate report from the National Oceanic and Atmospheric Administration (NOAA) confirms that 2016 was the third consecutive year of record global heat.
On Thursday afternoon the American Meteorological Society published the 27th annual “State of the Climate” report, which verifies last year surpassed 2015 as the hottest since record keeping began in 1880.
Based on preliminary data, NASA and NOOA had made the same assessment back in January, but this week’s report is considered definitive.
“We’re scientists, and we’re providing objective information,” Jessica Blunden, a climate scientist at NOAA’s National Climatic Data Center in Asheville, N.C., told Yahoo News. “We don’t go into policy, but we provide the information for people who want to go further with that.”
According to the report, the effect of long-term global warming and a powerful El Niño early on pushed 2016 into record-setting warmth. The global average sea level reached a new record high last year as well, to 3.25 inches above the average level in 1993, which marks the beginning of the satellite altimeter record.
Scientists also said that the average Arctic land surface temperature continued to warm and global ice and snow cover continued to decline. Sea ice extents in the Antarctic hit record daily and monthly lows in August and November
... Deke Arndt, chief of the climate-monitoring branch at NOAA’s National Centers for Environmental Information, described the report as diagnostic when asked if anyone from the White House had weighed in on it or questioned its findings.
“This report is a diagnostic report. It basically diagnoses what is happening in the climate system,” Arndt said on a conference call. “It’s intended to provide intelligence to those sort of decision makers that you’re talking about.”
Concentrations of major greenhouse gases in the atmosphere also reached to new highs in 2016. For instance, the global average concentration of carbon dioxide (CO2), the primary driver of anthropogenic climate change, in the atmosphere reached 402.9 parts per million (ppm). This was the first time on record that CO2 concentration exceeded 400 ppm. The consensus of climate scientists is that the maximum safe level is 350.
