NOAA Climate Report Confirms 2016 Was Planet's Hottest Year on Record

During the state’s recent drought the Almaden Reservoir in San Jose went dry revealing in 2014 a car that had been dumped in the lake. The federal government’s latest National Climate Assessment says California can expect more extreme swings between

But the link between global change and human activity is not detailed in the study. The New York Times published a copy Monday.

There were 93 tropical cyclones across the globe, 13 percent more than normal. The damage is done and can't be hidden; the evidence is irrefutable.

But this is an unusual time, and what remains uncertain is whether the report now pass the test of an administration that has an unprecedented hostility to climate science and to some degree science itself.

"There are no alternative explanations, and no natural cycles are found in the observational record that can explain the observed changes in climate", says the report, citing thousands of peer-reviewed studies.

Prior to that, was considered the warmest year of 2015.

The year brought record breaking events, temperatures and sea levels, all of which were broken just one year earlier, in 2015. A record large El Nino, the warming of the central Pacific that changes weather worldwide, was also a big factor in last year's wild weather.

But as humanity continues to rely on fossil fuels for energy unprecedented levels of greenhouse gases are polluting the atmosphere, acting like a blanket to capture heat around the Earth, the report emphasized.

"Global temperature appears to be running behind 2016, comparable to 2015", said Deke Arndt, one of the report's co-authors.

Global annual average atmospheric Carbon dioxide concentration was 402.9 parts per million (ppm) which surpassed 400 ppm for the first time in the modern atmospheric measurement record and in ice core records dating back as far as 800,000 years, the NOAA said.

Past year surpassed 2015 as the warmest on record, confirming the continued trends of warming globally.

Scientists from all over the world have documented warming in the air and water, melting glaciers, disappearing snow, shrinking sea ice and rising sea level.

According to the report released Thursday, the global land and ocean surface temperature was 0.45°-0.56°C above the average for 1981 to 2010.

Global CO2 emissions (left) and probabilistic temperature outcomes of Paris (right). Carbon dioxide, methane and nitrous oxide, all drivers of atmospheric warming, recorded new highs past year, with carbon dioxide surpassing a milestone 400 parts per million for the first time in recent history.

In addition, the global average sea level rose to a new record high in 2016, and, according to the new report, was about 3.25 inches (82 mm) higher than that observed in 1993, when satellite record-keeping for sea level began.

The rate of warming in the Arctic, which is happening at twice the rate of the rest of the globe, has major impacts on local ecosystems, but also further drives the warming of the planet, as the sea ice that would reflect the sun's rays back to space is lost.

Trump has previously dismissed climate change as "a hoax".

Trump's advisers have plans to hold a public debate with researchers about global warming and climate change.
