Climate change report paints dire picture of global warming

Estimates show waters are rising because of melting glaciers and ice sheets, as well as thermal expansion of the ocean water as it warms.

A new report by 450 scientists from more than 60 countries finds irrefutable evidence that global temperatures are increasing at an alarming rate.

Headed by the National Oceanic and Atmospheric Administration and titled State of the Climate in 2016, the report based on data from thousands of studies is published as a 280-page supplement in the Bulletin of the American Meteorological Society.

The report considered a number of indicators showing that greenhouse gases, sea levels, ocean temperatures, and global temperatures, reached record highs in 2016. It also looked at the steady retreat of mountain glaciers.

The report found that concentrations of heat-trapping carbon monoxide have been steadily rising since 1980. They reached a record high in 2016, which marked the "largest one-year increase in the modern record," NOAA said.

Sea levels have been rising for decades and also hit a record high in 2016. Estimates show waters are rising because of melting glaciers and ice sheets, as well as thermal expansion of the ocean water as it warms.

Oceans are heating up and soared to a record high in 2106.

"Globally averaged sea surface temperatures were the highest on record in 2016," according to Climate Central, as reported by The Washington Post. "Global sea level was also the highest on record. The rate of warming and the rate of sea level rise in the global oceans are both accelerating."

As average global temperatures are increasing and the number of hot days seen worldwide has risen, mountain glaciers are retreating, with more ice being lost through melting than is gained with new snowfall.

"2016 was the globally averaged hottest year on record, surpassing 2015," Climate Central said. "The record warmth from the combined influence of long-term global warming and a strong El Nio early in the year. The 10 hottest years on record have all come since 1988."
