Meteorologists are seeing global warming's effect on the weather

[Ghost Dog]

Both NASA and local farmers confirm longer growing seasons, with more allergens, pests and invasive species. Rainfall rates are increasing; wet areas trending even wetter... A warmer atmosphere is increasing water vapor levels overhead, juicing storms...

In recent decades, weather patterns have appeared to become more sluggish and erratic, worldwide. Rapid warming of the Arctic may be impacting the jet stream, the high-speed river of air that whisks weather systems around the planet. These high-altitude winds are powered by north-south temperature gradients, which are being altered by rapid warming of northern latitudes.  Preliminary research suggests a drop in jet stream wind speeds, creating a “wavier” pattern where weather systems can become “stuck”. This translates into supernaturally-persistent blocking patterns, where weather stalls for extended periods of time. 

When weather goes into a holding pattern consequences can be severe: record rains; deeper, drier droughts; a longer, more intense wildfire season; and longer periods of life-threatening heat. Worldwide, record highs have exceeded record cold by asignificant margin. On July 31, 2015 the town of Bandar Mahshahr, Iran experienced a staggering heat index of 165°F. From relentless winter flooding in the UK to disruption of India’s monsoon to chronic fires in Indonesia to more midwinter rain and less snow from the Alps to the Rockies, the planet’s accelerating warming signal is now showing up in the weather...

1. but but but.... we had an ice storm 2 years ago

Unfortunately our right wing friends will come up with any little anecdote which in their feeble little minds disproves the fact that the earth is warming. They somehow convince themselves that they know more about the topic than thousands upon thousands of climate scientists who have spent years studying this.

3. jimie inhofe with a snowball proved there is no such thing!! on the other hand, this area is now

home to magnolia trees (apparently we have gone from zone 4 to zone 6), and I hear that they are growing olive trees in devonshire.

4. From the comments (for any 'doubters'):

NOAA's index shows that CO2 concentration has risen by an average of 1.76 parts per million since it was established in 1979, and that increase is accelerating. In the 1980s and 1990s, it rose about 1.5 ppm per year. Over the last five years, the rate of increase has been about 2.5 ppm, said Ed Dlugokencky, a senior scientist with NOAA's Earth Systems Research Laboratory who helped compile the inventory.

That means since 1990, global atmospheric CO2 has resulted in a 50 percent increase in its direct warming influence on climate, Dlugokencky said.

"This isn't a model. These are precise and accurate measurements, and they tell us about how humans are changing the balance of heat in the Earth system," said Jim Butler, director of NOAA's Global Monitoring Division, in a statement. "We're dialing up Earth's thermostat in a way that will lock more heat into the ocean and atmosphere for thousands of years."

CO2 has been a primary driver of climate throughout the last half a billion years at least.

http://openearthsystems.org/data/readings/Introductory%20Reading/Royer2006-CO2climatePhanerozoic.pdf

A pervasive, tight correlation between CO2 and temperature is found both at coarse (10 my timescales) and fine resolutions up to the temporal limits of the data set (million-year timescales), indicating that CO2, operating in combination with many other factors such as solar luminosity and paleogeography, has imparted strong control over global temperatures for much of the Phanerozoic

The most important lessons drawn from geology are that the earth’s climate can change radically and that the pace of change can be rapid.

Geology also supports the theory that past periods of especially warm temperature were caused by high atmospheric carbon dioxide level

Earth systems respond to CO2 whether it comes from a natural process or from human activity.

There have been natural events in the very distant past, where volcanoes broke through fossil fuel deposits, set them on fire, and caused big rises in atmospheric CO2.

So that's an example of CO2 being produced by a natural process, one which has parallels with what's going on now.

However, those natural events burned a limited amount of fossil fuel and took tens of thousands of years, so human activity is replicating that process on a much bigger scale, and in only a few hundred years.

These are called 'hyperthermal events' and are correlated to extinction events, of varying degrees of severity.

There hasn't been a hyperthermal for tens of millions of years.

Ecosystems take a long time to recover, typically hundreds of thousands of years, in one case 10 million years.

6. We have been warned for a very loooong time. ...

This is the NUMBER ONE issue in the world today!
But we are too worried about emails, socialism, bad hair, he said, she said, to pay any attention in mass.

There is no leader of the cause, Al Gore is reduced to a CT quack.

Few have the critical thinking skills to see that even the rise in terrorism is linked directly to global warming. Study the causes of the Syrian troubles. Warming, drought, lack of food because farming is almost useless. Rural folk moved moved into the cities. There they found no jobs, lack of housing, poor living conditions in general. Is it any wonder they grasped at any way to have money to support themselves?

This is all documented in the series, "Years of Living Dangerously". I believe it was in the second episode. Most, if not all of the series can be found at YouTube. From the YouTube app I cannot find a way to supply a link. Just search for the title of the series at YouTube.

Thank you for your attention.

7. Ssshhhh... don't tell The Weather Channel!

It would make their attempt at corporate weather big-bucks quite annoying!

with love,

8. What with all the companies 'creating' weather, who can tell anymore

which weird weather pattern is caused by man or by global warming?
The answer is BOTH are created by man...one a reaction to the other.
