Posted on 01/29/2013 2:58:37 PM PST by ExxonPatrolUs
Crops shriveled to dust this summer while thermometers hit continuous triple digits in the Midwest and Southwest regions. Yet, what about the current snowmageddon occurring in our mountain regions, and record lows on the east coast?
Global warming is the all-encompassing term for what is happening to our planet today. As we increase the amount of anthropogenic pollutants in the air, we trap heat within our atmosphere. Yet, this seems contradictory if the weather channel reports on freezing temperatures and cold fronts nationwide.
What defines global warming is climate, not weather. Weather is what we see on a 10-day forecast, what dictates the clothes we wear, and if our flight will be delayed. Climate, on the other hand, is a compilation of weather over a minimum time span of 30 years. This provides a baseline to compare historical climate patterns, and gives an overall picture of what the weather has been doing for three or more decades.
Numerous reports from the Intergovernmental Panel on Climate Change show that the facts are undeniable: our climate is changing at an unprecedented rate. Scientists now examine ice cores that date back 400,000 years, which serve as atmospheric fossils after having trapped small air bubbles under layers of snow and ice. This historical data shows a global trend of increasing climate temperatures when compared to pre-industrial eras. Although natural events like the solar cycle alter climate, these occurrences alone cannot account for the rate of change that scientists see today.
The average global temperature is still increasing despite the cold winters we experience. The atmosphere is unable to let heat escape due to an increase in greenhouse gases such as carbon dioxide, methane and VOCs that are released during many industrial processes. Once these gases enter the troposphere and stratosphere, heat is trapped close to the surface of the earth.
Earthjustice continues to push for strict regulations on power plants and cement kilns, two mega-producers of greenhouse gases. Learn more about the latest victories that promote stringent requirements for air standards and emissions.
Is there global warming?
Well over what period? 18,000 years ago Detroit was under 3 miles of ice.
Was it man made? No. Does man have control over it? No.

“we have found something, no matter how flimsy, to use to get POWER!! We will wield it like a club and laugh at how we make so many dance to our tune!”
Mean temperatures have been declining for 2 decades (I need to look up the reference but it was noted the other day).
And when it melted, it melted FAST!
And when it melted, it melted FAST!
Man Made Global Warming believers have to be confronted by a glaring requirement of science, called a “negative case”.
Simply put, “What happens if there *isn’t* Man Made Global Warming?” (And no circular arguments, like “Then there isn’t Man Made Global Warming.”)
Right now, the MMGW believers are asserting that *everything* proves that MMGW exists. But they have zero credibility until they can name conditions that happen when there *isn’t* MMGW.
That is, some are claiming hot weather is caused by MMGW; but so is cold weather and temperate weather. Adverse weather and ordinary weather. etc.
That is not science. Even simple, basic, science experiments demand to know what happens to a control group, an identical group that isn’t being experimented on. And without this control group, a negative case, the experiment cannot be proven beyond coincidence.
the facts are undeniable, the IPC fudged the numbers.
Yes, they should have lost credibility when global warming could be blamed for unusually cold winters and blizzards.
But we aren’t dealing with rational people, but extremists who use “climate change” to justify micromanaging every one and controlling the population.
Not according to NASA. Temps have been stable for fifteen years while CO2 has continued to increase.
