Climate change in 2016 — and continuing into 2017 — has brought the planet into “truly uncharted territory”

A new report confirms that last year brought record global temperatures, exceptionally low sea ice, and unabated sea level rise

Yesterday I reported that even though the warming influence of El Niño is long gone, February of 2017 brought very little letup in global warming.

Now, the World Meteorological Organization is confirming that 2016’s “extreme weather and climate conditions have continued into 2017.”

The report released by the WMO yesterday finds that 2016 brought record global temperatures, as well as exceptionally low sea ice at both poles, unabated sea level rise, and continuing accumulation of heat in the ocean. And those trends appear to be continuing.

“Even without a strong El Niño in 2017, we are seeing other remarkable changes across the planet that are challenging the limits of our understanding of the climate system, said World Climate Research Programme Director David Carlson, in a WMO press release. We are now in truly uncharted territory.”

Here’s are some key numbers from the report:

Warming continued in 2016, setting a new temperature record of approximately 1.1 °C above the pre-industrial period, and 0.06 °C above the previous highest value set in 2015. Carbon dioxide (CO2) reached new highs at 400.0 ± 0.1 ppm in the atmosphere at the end of 2015. Global sea-ice extent dropped more than 4 million km2 below average – an unprecedented anomaly – in November. Global sea levels rose strongly during the 2015/2016 El Niño, with the early 2016 values making new records.

The report points unequivocally at emissions of greenhouse gases from human activities as the primary cause of global warming, and the resulting decline in sea and land ice, as well as the long-term rise in sea level.

“With levels of carbon dioxide in the atmosphere consistently breaking new records, the influence of human activities on the climate system has become more and more evident,” said WMO Secretary-General Petteri Taalas.

Each one of the 16 years since 2001 has been at least 0.4 °C above the long-term average of the 1961-1990 base period, which is used by the WMO as a reference for climate-change monitoring. Over the long term, global temperatures have been rising at a rate of 0.1 °C to 0.2 °C per decade, according to the WMO report.

Meanwhile, President Donald Trump seems determined to continue denying the scientific reality of climate change. Even as the WMO report was made public yesterday, the Trump administration was laying plans to gut U.S. efforts to curb climate change. As the New York Times reported:

WASHINGTON — President Trump is poised in the coming days to announce his plans to dismantle the centerpiece of President Barack Obama’s climate change legacy, while also gutting several smaller but significant policies aimed at curbing global warming.

The moves are intended to send an unmistakable signal to the nation and the world that Mr. Trump intends to follow through on his campaign vows to rip apart every element of what the president has called Mr. Obama’s “stupid” policies to address climate change. The timing and exact form of the announcement remain unsettled, however.

But there actually is some good climate news to report today: According to a new study, with just one change in dietary habits between 2004 and 2014, Americans avoided pumping 185 million metric tons of climate-warming greenhouse gases into the atmosphere. That’s equivalent to the annual CO2 emissions from 39 million cars.

What was the dietary change? Americans consumed 19 percent less beef.

Other dietary changes, including reduced consumption of carbon-intensive foods such as orange juice and frozen potatoes, boosted the CO2 savings to 271 million metric tons of greenhouse gases, equivalent to the annual emissions of 57 million cars.

Mind you, I definitely enjoy a bacon cheese burger washed down with a nice local brew. But for me at least, these new findings suggest that even modest changes in my habits can have a fairly significant impact.

    AGW is nothing but FRAUD only the mentally challenged believe in.

    A simple greenhouse test:

    – 20x20x8′ greenhouse has 3,200 cubic feet
    – The amount of CO2 is 1.28 cubic feet
    – Does any grown sane adult honestly believe adding or removing 1 cubic foot of CO2 from the greenhouse is going to magically change the temperature by 2C?

    If this was true why would anyone need to pay for energy to heat their house? All they would need to do is put a clear bubble on their roof and fill it with 100% CO2.

    – The amount of CO2 increase since 1960 is equal to 7x7x7″ in the greenhouse. Does anyone think this makes a difference?

    – The fact is 224 cubic feet of CO2 is required to make the greenhouse temperature rise by 1C, about 70,000 PPM.

    MSM and governments are scam artists, brainwashing the ignorant masses with fairy tales while they are taxed into oblivion.

      I was paid 104000 bucks previous 12 months by doing an on-line job and also I was able to do it by w­orking in my own time f­o­r several hours on a daily basis. I applied work opportunity I found out on the net and I am delighted that I was capable of to make such good money. It is actually newbie-friendly and I am so delighted that I found out about it. Take a look at exactly what I do… http://shrty­.­link/BaQXOB

    Good to see a Globalist Organization taking the lead in saving humankind from The World’s Greatest Threat, Global Warming or Climate Change.

    About time these Globalist Elites paid their fair share of the cost of keeping the planet safe from bad weather.

    But where’s the money?

    The U.S. can’t do it alone. NOAA and NASA and the other alphabet agencies cannot be expected to bear the financial burden alone, when the U.S. is $20,000,000,000.00 already in debt and counting!

    We are already saving the world from totalitarianism with NATO in Europe, with 3 wars in the Middle East, and with SEATO in Asia, with Korea and China. Besides there’s that Space Program that presently relies on Vladimir Putin (of all people LOL) to give our astronauts a ride to the space station.

    And just for the record, that “World Meteorological Organization” Press Release was issued by David Carlson, Director of The World Climate Research Programme, another entity entirely.

        There’s something unbalanced and nonsensical about a partisan political party trying to set the regulations for the free speech of their politic opponents.

        It requires a great deal of faith and true belief that you know best, and that other folks are just “deplorables”.

        We saw lots of “deplorables” sent to the gas chambers, Gulags Mental Hospitals, and concentration camps not too long ago, by these kinds of people!

    Donald Trump is a ignorant moron. A global rebellion against this fool is called for. He is commiting the future world to unlivable conditions.

      I was paid 104000 bucks past 12 month period by doing a web based job as well as I was able to do it by w­orking in my own time f­o­r quite a few hours each day. I applied job opportunity I stumbled upon online and so I am delighted that I was in the position to make such decent cash. It is actually newbie-friendly and therefore I’m so blessed that I found out regarding it. Have a look at what I do… http://secure10­.­weebly­.­com
