U.s. scientists officially declare 2016 the hottest year on record. that makes three in a row. – the washington post electricity physics problems


The record comes two days before Donald Trump, who has tweeted that global warming is a “hoax,” assumes the presidency and, with it, control over the two science agencies that announced these records. It is also the same day that Scott Pruitt, Trump’s controversial nominee for the Environmental Protection Agency la gastronomie, is appearing before the Senate in an often-tense confirmation hearing in which he has been questioned about climate change. Pruitt has previously written that the “debate” over climate change is “far from settled.”

Trump’s other nominees, such as State Department nominee Rex Tillerson and Interior Department nominee Ryan Zinke, have been less dismissive of climate change in their confirmation hearings, acknowledging at least some human contribution to the phenomenon but also raising questions either about the extent to which it is human-caused or about our capacity to predict the consequences. On Wednesday gas and supply acworth ga, Pruitt acknowledged that climate change is not a “hoax” and said that “the climate is changing, and human activity contributes to that in some manner.”

NASA and NOAA produce slightly different records using somewhat different methodologies, but have now concurred on identifying 2014 electricity lab activities, 2015 and 2016 as, successively, the three warmest years in their records. There was a noticeable difference this year, however, in how much two agencies judged 2016 to have surpassed 2015. NASA was more bullish — a difference that Schmidt, in a press call Wednesday, attributed to different ways of measuring the Arctic.

Last year’s warmth was partly enhanced by a strong weather pattern known as El Niño, but the federal scientists underscore that this was not the only cause. For example, 1998 was also, at the time, the warmest year on record, thanks in part to a strong El Niño — but the 2016 planetary temperature now far surpasses the temperature of that year, as you ortega y gasset la rebelion de las masas can see above. The reason is that Earth has been warming since then, allowing another El Niño event, unlocking heat from the vast Pacific Ocean, to push overall temperatures to new heights.

Thus do natural wobbles of the planet’s temperature interact with an overall warming gas 02 trend to produce records on a regular basis. At present, that means that while scientists would expect 2017 to be quite warm, relative to, say, a year in the 1990s, there has been little talk of a fourth record year in a row. And, indeed, El Niño has subsided.

Two other global agencies, the Japan Meteorological Agency and Britain’s Hadley Center, also track global temperatures. On Wednesday, the Hadley Center also announced that 2016 was the warmest year on record, albeit only “nominally” because it was very close to 2015 in the agency’s data gas zombies set. The center reported that while 2016 was .77 degrees Celsius above the temperature average between 1961 and 1990, 2015 was very close at .76 degrees Celsius higher.

NASA further noted in its analysis that electricity japan compared with the late 19th century, the planet has now warmed about 1.1 degrees Celsius, or 2 degrees Fahrenheit. That’s significant because the global community has been striving to limit overall warming to considerably below a 2 degree Celsius rise, and even, if possible, to hold it to a 1.5 degree Celsius increase. That is now about .4 degrees away, in Celsius, based on these figures.

“It is the second year in a row that the annual global temperature has been more than 1 Celsius degree higher than the pre-industrial level, and shows that the world is moving ever closer to the warming threshold of 1.5 Celsius degrees, beyond gasset y ortega biografia which many scientists have concluded the impacts of climate change will be unacceptably dangerous,” said Bob Ward, who is director of policy and communications director at the Grantham Research Institute on Climate Change and the Environment, part of the London School of Economics and Political Science.

Last year’s warmth was manifested across the planet, from the warm tropical ocean waters off the coast of northeastern Australia, where the Great Barrier Reef experienced its gas definition chemistry worst coral bleaching event on record and large scale coral death, to the Arctic, where sea ice hit regular monthly record lows and overall temperatures were also the warmest on record, at least from January through September 2016.

Among major 2016 events, the devastating bleaching of the Great Barrier Reef did not stand alone. In a catalogue of some of the extremes the planet witnessed during the year, NOAA also noted the megafire that engulfed Fort McMurray, in Alberta, Canada, at the electricity voltage in india beginning of May, relatively early in the year for wildfires. That event was certainly consistent with a warming climate, as well as with the role of El Niño, although scientists are reluctant to formally say that climate 2015 electricity increase change has played a role in an individual event without conducting extensive analysis.

“The pattern of record warmth in the lower atmosphere, coupled with record cold in the stratosphere, provides a clear fingerprint of the cause of the unprecedented warming — greenhouse gases trapping heat in the lower atmosphere instead of letting it escape to the stratosphere, and then to space. No doubt about it anymore — humans, mainly by burning fossil fuels, are cooking the planet,” Overpeck said.
