Global Warming? Then why is it so cold?!?!

[Occams Barber]

I was sitting around the other day in damp, sweaty undies, perspiring buckets, in 100f/37c heat and 80% humidity, when it occurred to me that you poor babies, up in the north of the Northern Hemisphere, were probably freezing your bitts off in the latest Extreme Cold Snap or Raging Blizzard or Snow Bomb.

So… (I said to myself) if the Globe is Warming, why are these unfortunate people suffering through conditions so extremely cold that they were forced to wear socks? Consulting my Interwebs I found out that the The Answer is - the Polar Vortex.

While it may sound like the latest Marvel Superhero, the Polar Vortex is actually a fast-moving band of air which circles the polar regions trapping the freezing cold, dense Arctic air mass and preventing it from flowing southward. (There’s a similar set up at the South Pole over Antarctica).

Global warming has decreased the sea ice cover in Polar regions and warmed the ocean. Less winter sea ice allows a warmer ocean to radiate heat which in turn warms the Vortex weakening its ability to contain cold Polar air. Once the Vortex is weakened, cold dense Arctic air is able to flow out and is sucked south towards warmer, lower density air located closer to the Equator. The result; huge ‘blobs’ of cold Arctic air spill out over the North East of North America. When Climate and Weather intersect in just the right way the result is the extreme cold events you’ve all been complaining about.

So… (you ask) if this also happens at the South Pole, how come Australia isn’t up to its belly button in that white fluffy stuff each winter?

Simple.

Australian ingenuity.

At the start of winter, the entire population of Australia decamps to line the beaches on the southern coast of the continent. There we cover ourselves with rendered kangaroo fat and dance naked on the shore while vigorously waving burning sticks at the sky. (For safety reasons kiddies are limited to Sparklers.)

Works every time.

Global Warming is the ozone depletion, do you see that the sunshine stings nowadays when you take a sunbath it wont be good anymore.

Global warming and ozone depletion are not directly related, although global warming does indirectly cool the stratosphere, which encourages ozone depletion. Both are the result of atmospheric pollutants, but of different kinds - see Is There A Connection Between The Ozone Hole and Global Warming?

Though coincidentally one of the replacements for CFCs turned out to be a big Greenhouse type gas which has required international agreements to phase out.

Did you by saying 'global warming' actually mean 'climate change'?

I was trying to explain how global warming can cause extremes of cold weather. 'Warm' causing 'cold' is (understandably) a counter intuitive concept.

My understanding is that global warming is the major cause of climate change. Extreme cold weather events, if they remain a long term fixture of climate, are examples of climate change.

Look at how the "global temperatures" to $prove$ global warming are collected....it's a giant $cam. They collect it from areas that skew the data drastically and support their already predetermined tax payer funded conclu$$ion. We have a lot of $cientists today that parrot rubbish instead of actually examining the data and looking for cofounding factors.

Is that meant to be confounding? If not, what is a cofounding factor?

Yes, unless you think there is a cofounding factor.

 

[Ophiolite]

No, but you appeared to, since you've used "cofounding" at least twice. Thank you for clarifying. Will you be producing a clear example of this any time soon, or a reference back to a post/thread where you have done so?

I frequently make typos...it doesn't take away from the context. Don't derail the "Global Warming" topic. I did produce a clear example above.

Look at your posts from the point of view of your average reader.

You're constantly complaining about a huge conspiracy including most of the world's climate scientists, many prestigious scientific institutions, governments and the UN. You make these claims without producing a scrap of evidence and when questioned you accuse others of not researching the topic.

You've been doing this for years.

Isn't it about time YOU put the evidence on the table? - Or do we assume you're just another Illuminati double agent running a false flag operation?

Global warming is a subset of climate change and can be used interchangeably.

 

[OldWiseGuy]

Seventy percent of the globe's surface is oceans.
The oceans are warming,
Therefore there is global warming,
Which causes climate change,
Therefore there is climate change.

The earth is on a normal natural cycle. Warm periods and Ice Ages come and go naturally. This is caused by the sun "breathing". Of course, those of us here know full well that the Almighty God is in full control.
There was a short "heating spell" which comes just before the temperatures start coming down. The so-called global warming ended in 2008. We are now on a slow-but-sure plunge into the next Ice Age.

Nonsense, the warmest years on record have been the last few years! Scientists are well aware of the solar cycle, and take it into account.

The weather has become a political issue, which is ever so stupid. Don't get your science from politicians. Listen the actual scientists. The short-span of global warming ended in 2008. Record heat reported on the news since has been nothing more than political lies. Global tempts are falling; getting colder.

The actual scientists, those collecting and analysing the data are quite clear, anthropogenic climate change is happening.

 

[Occams Barber]

Listen the actual scientists.

Here's a report produced by the 'actual scientists' clearly demonstrating that it's getting warmer.

The U.S. based National Oceanic & Atmospheric Administration (NOAA) recently published its annual Global Climate Report for 2017.

This is a brief summary of some of the global and Regional highlights/anomalies detailed in the Report:

Global highlights/records

· 2017 was the third warmest year on record, since recording began in 1880, behind 2016 and 2015

· Including 2017, the six warmest years on record have all taken place since 2010

· 2017 is the 41st consecutive year with temperatures above the average for the 20th century

· From 1880 to 1980 a new temperature record was set, on average, every 13 years. For 1981 to 2017 a new record is set, on average, every three years.

· The average rate of temperature increase per decade for 1981 to 2017 is more than double the average, per decade, increase since 1880


Regional anomalies for 2017

· Arctic Sea Ice. Smallest annual maximum extent. Eighth smallest minimum extent

· Antarctic Sea Ice. Second smallest annual maximum extent. Smallest recorded minimum extent

· Europe. Fifth warmest year on record

· USA (contiguous). Third warmest year since 1895 behind 2012 and 2016

· Chile. Recorded the highest temperature (43.5c/110.3f) ever recorded so far south (430S)

· Argentina. Highest national temperature since recording began in 1961

· Africa. Fourth warmest year on record behind 2010, 2016, and 2015

· Asia. Third warmest year since recording began in 1910 behind 2015 and 2007

· Australia. Third warmest year since recording began in 1910. Seven out of 10 warmest years have occurred since 2005.
