Good question.

The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere. Studies are showing its changing the course of the jet stream, which steers weather systems from west to east, with “wavier” patterns – meaning steeper troughs and higher ridges that allow for cold fronts to come down from the north.
Arctic Warming is Altering Weather Patterns, Study Shows

A "study, by Jennifer Francis of Rutgers University and Stephen Vavrus of the University of Wisconsin-Madison, ties rapid Arctic climate change to high-impact, extreme weather events in the U.S. and Europe.

The study shows that by changing the temperature balance between the Arctic and mid-latitudes, rapid Arctic warming is altering the course of the jet stream, which steers weather systems from west to east around the hemisphere. The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere, due to a combination of human emissions of greenhouse gases and unique feedbacks built into the Arctic climate system.

The jet stream, the study says, is becoming "wavier," with steeper troughs and higher ridges. Weather systems are progressing more slowly, raising the chances for long-duration extreme events, like droughts, floods, and heat waves.

"[The] tendency for weather to hang around longer is going to favor extreme weather conditions that are related to persistent weather patterns," said Francis, the study's lead author.

According to the study, Arctic climate change may increase the odds that such high-impact, blocking weather patterns will occur. The study cites examples of other patterns that led to extreme events that also may bear Arctic fingerprints, including the 2011 Texas drought and heat wave, which cost the state's agricultural sector a staggering $7.62 billion - making it the most expensive one-year drought in that state's history.

In addition, the study also mentions jet stream configurations that led to heavy snows in the Northeast and Europe during recent winters. Such events are also "consistent" with the study's findings, according to the paper.

The reasons why the Arctic is heating up so quickly, a phenomenon known as "Arctic amplification," has to do with factors that are unique to the Arctic environment, involving feedbacks between sea ice, snow, water vapor, and clouds. As the area warms in response to manmade greenhouse gases, melting ice and snow allow exposed land and water to absorb more of the Sun's heat, which melts more ice and snow, and so on. A relatively small amount of initial warming can be greatly magnified in the Far North.

The temperature contrast between the frigid Arctic and the milder mid-latitudes is what drives the powerful jet stream winds, which are so important for determining day-to-day weather conditions.

In addition to making the jet stream have more pronounced north/south swings, the reduced temperature gradient between northern and southern areas is causing the westerly component of upper-level winds to slow.

The westerly component of upper-level winds during the fall has weakened by about 14 percent since 1979, the study found.

A slight slowdown in the jet stream may not sound like a big deal. After all, jet stream winds have been clocked at upwards of 200 mph. But it turns out that slowing of the jet stream influences its shape and the motion of individual storm systems.

Weaker westerly winds causes the big north/south swings in the jet stream to move more slowly from west to east, making weather conditions in a given location more persistent than they used to be.

In other words, rapid Arctic warming is expected to exert a growing influence on the weather far beyond the Arctic Circle, for many years to come. "

And?

From a liberal organization!!!

Let's tax everyone for more power and control!!!

Why did Al Gore sold station to oil burning Muslims? Because you are a liberal easy to fool!!

Some places get colder others hitters, there is a balance in nature you Liberas want to ignore.

You only look at the heating places and totally ignore the colder places, and your fraudulent emails confirm such behavior.

The Scientist who only look at the warming admit, many secretly, that is is NOT caused by men!!! But they need the grant money coming!!!

You claim humans cause more Global Warming than a volcanic eruption and you are scientifically WRONG, embarrassingly wrong and stupidly wrong, ignorantly wrong and factually wrong!!!

Evidence: Climate change: How do we know?

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. Studying these climate data collected over many years reveal the signals of a changing climate.
Certain facts about Earth's climate are not in dispute:

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many JPL-designed instruments, such as AIRS. Increased levels of greenhouse gases must cause the Earth to warm in response.

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in solar output, in the Earth’s orbit, and in greenhouse gas levels. They also show that in the past, large changes in climate have happened very quickly, geologically-speaking: in tens of years, not in millions or even thousands.3
The evidence for rapid climate change is compelling:

• Sea level rise
Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century.4

• Global temperature rise
All three major global surface temperature reconstructions show that Earth has warmed since 1880.5 Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years.6 Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase.7

• Warming oceans
The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.8

• Shrinking ice sheets
The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.

• Declining Arctic sea ice
Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades.9

• Glacial retreat
Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.

• Extreme events
The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950.

• Ocean acidification
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.12,13 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.14,15

1) Al Gore is not a scientist, and only passes on the scientific view as a spokesman. Taking out the representative does not remove the REALITY of the science on global warming.

2) Al jazeera is a well respected, world renown newspaper.
It is deranged to say every Arab country represents oil. So is every Texan an evil oil person with an oil derrick in their backyard?

Wallop10 has already shown how clueless most of your thoughts are.

Just remember that a properly-designed carbon tax would be REVENUE-NEUTRAL. This means that the total change in the size & financing of government is ZERO. The total amount of money removed from the private economy by the government is ZERO.

A carbon tax can be very stiff & very effective while still being revenue neutral. It's a Pigouvian tax that takes money from high carbon emitters & gives EXACTLY the same amount of money to low carbon emitters.

This punishes high carbon emitting individuals & companies while stimulating low carbon emitters to exactly the same extent. It may be very inconvenient for some, & would be a major adjustment, but it would be a tremendous boon for others.

Imagine a stiff carbon tax paid by producers of fossil fuels, especially the "dirtiest" one, coal, & the ones that emit unburned methane into the atmosphere. We already levy taxes on these things & have inspectors to see that they're paid, but the taxes are far, FAR too low.

100% of that tax could be paid out to every citizen (or legal resident) equally on a monthly basis. The costs for the computers & checks would be trivial. OK, maybe you'd have to have a few extra census workers or whomever to keep track of people.

(I'm not proposing this as the best or most practical way of making a tax revenue-neutral, BTW, just a way to easily imagine it.)

If you're a high carbon emitter, you pay thru the nose. If you're a low carbon emitter, though, you get free money, literally for nothing but living here & breathing.

In this theoretical proposal, you'd be able to easily return ~99% of the tax directly to the people. It'd be a major stimulus to invest in, & build, renewable energy technologies.

It would be inconvenient, yes, but a WHOLE lot less inconvenient, & way, way, WAY cheaper, than allowing AGW/CC to progress without mitigation. It would also give us a better bargaining position to negotiate with China, India & the rest of the world so that all need to reduce emissions.

Or maybe you think the Chinese ENJOY trying to breathe the air in Beijing? They WILL clean up, & they WILL reduce their emissions. They don't want to see Shanghai under water.

We are the country most responsible for current warming, so we should take the lead. Lots of other countries have carbon taxes, & their economies haven't collapsed.
