Global warming is really hitting us hard

From your source:
"Arctic sea ice reflects sunlight, keeping the polar regions cool and moderating global climate. According to scientific measurements, Arctic sea ice has declined dramatically over at least the past thirty years, with the most extreme decline seen in the summer melt season."

Volcanic eruptions and the particulate matter released into the atmosphere can have a cooling effect by blocking the suns rays

:rofl Yes,everything is global warming....EVERYTHING.

You guys would be a lot more credible if you did some reading about the subject. The study of the Greenhouse Effect is nothing new and Al Gore didn't invent it. There are many articles and studies by universities and some of the brightest scientists in the world. To form an opinion by what you hear on Fox News is just being lazy. Rush, Hannity and Glen Beck are not experts on the subject.
I studied The Greenhouse effect and manmade climate change in college back in the 70s. There is even more evidence now than there was then that we are changing our climate.

The Greenhouse Effect

Your side would be more credible if you didn't claim that every extremity is caused by global warming.

Btw- Show me where I ever quoted any of them.
 
Of course not because nothing can disprove GW theory. :mrgreen:

Nobody is denying that the earth has heated up. The question is, whether it is natural or man made... From what I've read, man has very little to do with it.
 
It was 80 degrees here yesterday. Hottest winter in 10 years. lol

You, in this very same thread:

What I'm saying is, that if the so called "experts" that claim that they are all knowing when it comes to climate change were correct, then we would still be getting warmer and warmer... but we aren't. Yet so many people still subscribe to their conclusions like they were handed down from god, rather than Al Gore.


So, to respond to your post, I'd say that YOU are in fact arguing that the world is not warming.

Grim, if the warming is not being induced by greenhouse gasses then why is the stratosphere cooling and why has there been a decrease in outgoing longwave radiation?
 
"First, we turn to the reconstruction of the rise of carbon dioxide since the time of James Watt. The early part of the series is derived from extracting air in polar ice, and measuring its carbon dioxide content. The later part is based on the measurements of Charles D. Keeling, since 1957, on Mauna Loa.

The overall rise is from just below 280 ppm (the “pre-industrial” value) to the present values above 360 ppm, an increase of a factor of 1.3. The logarithm of 1.3 is 0.11, that of 2 is 0.30. Thus, we are a little more than one third of the way to a doubling of carbon dioxide, on a log scale. If doubling of carbon dioxide produces a temperature rise of between 1.5 and 5 degrees Celsius (as found in numerical experiments using climate models), we should see a warming of between 0.5 and 1.7 degrees Celsius. We do see the lower number of this range, but this does not prove that the rise upon doubling of carbon dioxide is in fact 1.5 degrees. The reason is that we are in a “transient”, that is, the change is too fast to allow equilibrium to establish itself.

Graph showing rise of CO2, from measurements in ice cores (Siple, Antarctica) and measurements from Mauna Loa, Hawaii (Keeling curve) since James Watt, inventor of the steam engine. (Pre-1990 data in: B. Moore & D. Schimel, 1992. Trace Gases and the Biosphere. UCAR, Boulder CO)
In fact, the answer is not known with a high degree of certainty, not only because of the lack-of-equlibrium problem (which involves uptake of heat by the ocean), but also because of additional complexities arising from air pollution, trace gases other than carbon dioxide, possible changes in the brightness of the Sun, and effects from volcanic activity."
 
How about SO2 Aeresols in the upper atmosphere blocking sunlight?


NASA: TERRA (EOS AM-1) - About Terra


Who is measuring the SO2 Aeresol levels?


Here are some erratic measurements of lower atmosphiric SO2 which frorms acid rain.



Atmospheric sulfur dioxide and sulfate. Distribution of concentration at urban and nonurban sites in United States - Environmental Science & Technology (ACS Publications)


Thre is a small amount of acid rain from Aersol SO2, but Aersol SO2 generaly stays in the upper atmosphere, in varying levels of concentrations, increasing when volcanoes kick SO2 high into the upper atmosphere.

Arctic summer ice has been increasing since 2008, Alaska volcanoes.

Atmospheric Aerosols


"Three types of aerosols significantly affect the Earth's climate. The first is the volcanic aerosol layer which forms in the stratosphere after major volcanic eruptions like Mt. Pinatubo. The dominant aerosol layer is actually formed by sulfur dioxide gas which is converted to droplets of sulfuric acid in the stratosphere over the course of a week to several months after the eruption (Fig. 1). Winds in the stratosphere spread the aerosols until they practically cover the globe. Once formed, these aerosols stay in the stratosphere for about two years. They reflect sunlight, reducing the amount of energy reaching the lower atmosphere and the Earth's surface, cooling them."



Atmospheric Aerosols: What Are They, and Why Are They So Important
 
Sure it's pretty simple. As global temperatures have increased, so have sea surface temperatures. Warmer oceans evaporate more water vapor into the atmosphere creating new weather patterns.
Record snow falls could be part of it.
NOAA - National Oceanic and Atmospheric Administration - Scientific Assessment Captures Effects of a Changing Climate on Extreme Weather Events in North America

Water vapor has always evaporated into the atmosphere, whether the ocean is warm or cold. The cycle of life is that humans give off carbon dioxide C02 that plants use and in turn give of oxygen, O2. It is factories belching out fumes from smokestacks and car exhausts giving out carbon monoxide, C01 that causes pollution. This concept of greenhouse gases, C02 is part of the cycle of life, not bad. This whole theory put out by NOAA sounds a bit far fetched to me, and more like cowtowing to the present administration. Depending on who is President governs how government agencies work. When Bush was in, NOAA never talked of global warming. Now Obama is in. He is pushing global warming so now NOAA publishes article after article and quite biased all to make Obama happy. Just having a PHD doesn't necessarily make one all knowledgeable.

Abnormally hot days and nights, along with heat waves, are very likely to become more common.

  • Cold nights are very likely to become less common.

  • Sea ice extent is expected to continue to decrease and may even disappear in the Arctic Ocean in summer in coming decades.

  • Precipitation, on average, is likely to be less frequent but more intense.

  • Droughts are likely to become more frequent and severe in some regions.

  • Hurricanes will likely have increased precipitation and wind.

  • The strongest cold-season storms in the Atlantic and Pacific are likely to produce stronger winds and higher extreme wave heights.



It's winter time, and I am sitting here shivering as I type. I'm in the southeast, and we have had one of the coldest winters imagined.

Ice bergs tend to melt and not be as plentiful in summer Arctic conditions.

I live in the hurricane capital of the world, but hurricanes have become less frequent, ever since Hurricane Katrina devastated the Gulf Coast. Meterologists have had to throw out weather computer models.

We have had a great deal of precipitation this winter.

So much for those predictions.

Burning fossil fuel releases billions of tons of CO2 into the atmosphere above the natural occurring CO2. Carbon monoxide and Sulfer dioxide have been dramatically reduced since pollution control measures have been taken. That is evident in places like LA.

Water evaperates faster from warmer water and ocean temps are rising which leads to more precipitation in some areas and higher temps lead to drought conditions in others.

Global warming leads to change in weather patterns and extremes in weather.


"Just having a PHD doesn't necessarily make one all knowledgeable."
No but it makes them more knowledgeable than the pundits on Fox News.

Who would you rather learn science from? A scientist, a politician or a journalist?

Those predictions are over the long run, it is not about local weather forecasts.
 
Here is a map of the 877 snow fall records set last week.

Every time the counter AGW crowd starts a thread like this, your credibility as a political force is severely weakened.
 
Just one of many I read.

Roy Spencer, Ph. D.

Anyone that brings up Al Gore when talking about the Greenhouse Effect and global warming is purely political and loses all credibilty.
I would wager you just googled that.
