Is It Happening?

Yes. Earth is already showing many signs of worldwide climate change.

• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.

• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

• Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.

• Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.

• Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise.

• An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.

I say ground all aircraft.

The day after 911 when planes were grounded there was an immediate climate change.

So ground them all.

IF Global Warming/Climate Change is a SERIOUS problem then take the quickest steps to reduce burning petrochemicals with the least impact on the USA.

Ground all airplanes.

Exactly, this is precisely the point.
Look at all the evidence which clearly shows that for the past 11500 years our Iceage is in a warming (receding) phase. Is this bad? If one 'believes' that at some point in the last 150 years the weather was PERFECT for life on Earth this logically can be considered harmful. If one believes that there is such a thing as a tipping point for a warming Earth then one might also 'believe' this warming is harmful. In other words; Exiting an Iceage is bad if one believes that the science is so robust that it MUST be true. As a person who lacks a degree in climatology all I can do is to have 'faith' that the experts know what they are talking about. Therein resides the issue. To accept and believe in catastrophic anthropogenic climate change based on my faith in the people who proclaim it iseems more of a religious experience than a scientific one.

What scenario would falsify CACC? Until that question is answered... this issue will remain a religious question.

"An instrument near the summit of Mauna Loa in Hawaii has recorded a long-awaited climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement—and probably more than 3 million years of Earth history." Humans have never lived on this planet when CO2 levels in the atmosphere were at or above 400ppm. Thanks a lot deniers .You just doomed all of us to a death sentence.

Either "blt-grounds" doesn't like airplanes or it likes grounds in its coffee. Too bad, since aviation has worked so hard to raise jet 'passenger-miles per gallon' from 20 to 90-100. Contrast that with the auto industry that has raised corporate fleet mpg from.....what(?)......16mpg to 20mpg........ v. lately to 20+mpg?

I wonder how you alarmist survive in our world?

For instance, I'm sure none of you would ever be so hypocritical and drive a car or fly on a jet. Which leads to another question.....do you have little generators with pedals to power your laptops?

Check this out: http://calculator.carbonfootprint.com/calcula... "Payments for ecosystem services (PES), also known as payments for environmental services (or benefits), are incentives offered to farmers or landowners in exchange for managing their land to provide some sort of ecological service. They have been defined as "a transparent system for the additional provision of environmental services through conditional payments to voluntary providers."[1] These programmes promote the conservation of natural resources in the marketplace."[^ Tacconi, L.(2012). Redefining payments for environmental services. Ecological Economics, 73(1): 29-36.]

Look, you can get all the CO2 you want into your lungs as people have told you here the way.

Here's from the records: From 1751 to 1995, the cumulative global total CO2 emissions from fossil fuel production were 250x10^^9 tonnes C. Only 25% of this total was emitted by 1950, 50% by 1973, and 75% by 1985.

Who measures fossil fuel consumption? Do you think somebody keeps track of whether you're keeping a fuel reserve or burning every drop you buy? Even if true, natural sources of CO2 far exceed man's emissions.

Coincidence isn't causality, there's more loud music now, maybe that causes climate change. We've got the same number of experiments testing that hypothesis as AGW = zero.

Atmospheric CO2 hasn't been this high for 3 million years of the planet's existence. The last time the Earth was at or above 400ppm humans did not exist . Get it Now, BrianG?:-/

400ppm X 3 = A safe level of CO2 in the air... It is logical.
