The greenhouse effect has been accepted science for over a century.

Fourier calculates colder earth without an atmosphere (1824)

Tyndall discovers relationship between CO2 and long-wave radiation (1859)

Arrhenius calculates global warming from anthropogenic CO2 (1896)

Chamberlin models global carbon exchange including feedbacks (1897)

Callendar predicts global warming increase catalysed by CO2 emissions (1938)

Revelle predicts inability of oceans to sequester anthropogenic CO2 (1958)

from "The Discovery of Global Warming" by Spencer Weart

the greenhouse gas effect was first proposed by Joseph Fourier in 1824, proven to exist by John Tyndall in 1858, and was first quantified by Svante Arrhenius ~1896.

Arrhnenius' estimate, for how much warming to expect from a doubling of CO2 concentration in the atmosphere, was very close to today's estimates, which have 100 more years of research to rely on.

But for Rush Limbaugh and the Republicans and tea baggers, Global Warming is just an agenda cooked up by Al Gore and other liberals.

trying to get the elites head out of their dark place and do something to improve energy before it is too late is the hard part. even with the economy low, it does not have to take millions. cutting the subsidies to oil companies whose profits are obscene would be a good step. this could be funnelled into alternative sources. solar,geothermal...are worthwhile.

I have yet to find a scientific article which spells out exactly what the human race must do to avoid this global climate change. Do we go back to riding horses, or living in caves.....just what the hell is their solution!!!???

Climate change has been perhaps the one constant in Earth's history. It isn't news, and it isn't to be feared, commie libs.

scientists=thieves with a diploma.
Deserts used to be oceans millions of years ago.
By the way,who can manipulate the clime even if we stop all activities at once????show me and i may believe,and only then maybe.

The climate is always changing. The glaciers melt, the oceans rise. The glaciers grow, the oceans shrink. This is normal behaviour for the planet Earth. Nobody is denying that. "Climate change denial" is one of those leftist buzzwords for those who don't want to go along with the Liberals half-baked ideas on what needs to be done about it. We need real solutions for real problems, not empty rhetoric and name-calling.

On Climate Change.. The climate cycles are in a natural and normal upward rise, part of the cycles that ice deposit analysis shows has been going on for millions of years! Unless Obama moves the North Pole out of the Arctic ocean, they will continue; it is a physical event, and Obama cannot change the laws of Physics OR the location of the poles!

This was all analyzed by early computer work, and so far nobody I have seen has refuted the basic computer studies that show why we have the regular cycles of hot and cold weather the ice records have shown!

Our politically-oriented scientists ignore the basic periodicity and make it seem like this is a new thing and we have to prevent it, when it has been going on for millions of years!

Actually, we know that Iceland grew great crops before the cold period moved in. Is this not a part of History? Greenland had huge forests thousands of years ago; look it up!

If Greenland had forests, the climate must have been much warmer than today, and Polar Bears are still around!! So are people!

But trace the flow of money through Politicians, and you will get some concepts on what is really going on!

ask the alaskans whose permafrost is mushy if it is real.

We are at the tail end of an ice age. We know that the Earth warms and heats in cycles from ice cores samples taken in the Antartic. Mars is getting warmer along with the rest of the Solar System. How much research funding has been spent to determine the impact all of this cyclical activity. Our "greenhouse gas" emissions can't be the cause of Mars' recent warming can it??

I get a kick out of all you global warmers.. You cry about it while you are running your dish washer with you heat set a 75 and you get in your cars to do what ever. Turn your heat off catch your water from the rain. get on your bike and shut up

an old man said,"still gets cold and snows in the winter...still warms up and plants grow in the spring...gets hot in the summer..gets cooler and the leaves fall in the fall.....and i thought cool!!!!! forgot to ask if he had a degree!!!!!!

It is transparently obvious to what lengths the tobacco industry went to hide, deny and play down the dangers of cigarette smoke, yet deniers can't seem to imagine the same kind of agenda when it comes to the fossil fuel industry, which has an even larger financial stake in denying scientific evidence. The fossil fuel industry makes the tobacco industry look like a mom and pop grocery store by comparison. It's the biggest economic enterprise in the history of the world. And it isn't going to give up easy.

Can you say gullible and ideologically blinded?

Of course climate change is real. Do these people believe the Earth is always 72 degrees. Mother nature will change whenever she wishes. There is not a dam thing humans can do about it.

Let's look at the motives of the two groups involved in this dispute. Group #1 -- Thousands of Climate Scientists all over the world who agree that humans are causing global warming. What would their motive be for lying? I suppose more grant money for their studies? Group #2 -- Oil Company Executives and the politicians who are in their pockets. What would their motivation be for lying? Ummm, making millions of dollars. Who do you think is lying? I'm guessing the oil company executives. Global warming is man made. Why are you believing the oil company executives? Do you really think they have your best interest at heart?

We should really be quite concerned with a .5 degree change so much that we should ruin yet another 10 million jobs, and further the gap between the middle class and upper class.

Lets try to change something that is not real to bring forward more pain for the people, because 50 people not any better than anyone else THINKS it is worth it.

In other words, they want to continue to receive taxpayer money so they can continue to suck off the working public!!

Do you like Anthony Watts of Watts Up With That - "popular skeptic website)?

Here's how Watts operates.

Watts and D'Aleo make it all up with this claim

"NO WARMING TREND IN THE 351-YEAR CENTRAL ENGLAND TEMPERATURE RECORD"

Long story short, Anthony Watts (of Watts Up With That) and D'Aleo left out the 19th century and only used summer data, leaving out winter data, to arrive at their quackery graph. Of course summers in the period were relatively cool, while winters were relatively warm. Even for skeptics, this one takes the cake for cherry picking.

and they get their heads handed to them by Tamino at Open Mind blog. Tamino is a world class time series analyst, who is very knowledgeable about climate science. He regularly debunks the nonsense posted by Watts. Unfortunately, the public doesn't see much of that, as it never makes it into the mainstream media. But the junk sure does. The real science doesn't have the massive PR campaign to counter it.

Here's how vested interests, like the fossil fuel industry, keep up the facade of fake climate change skepticism. This is one of the biggest disinformation campaigns in history.
They spread their disinformation through these groups, who also hide the money trail, - 'wipe the oil' off the money.

These 32 organizations have all been involved in the tobacco industry's campaign to deny the science showing the dangers of tobacco.

They are all now involved in the campaign to deny the science of climate change.

#5 and #9 were created by the billionaire oil and lumber tycoon Koch brothers, who fund all kinds of anti-enviromental PR. They also fund denial of the science saying formaldahyde causes cancer. This is no surprise, since they are major owners of Georgia Pacific lumber company.

Acidification of the oceans, as a result of the excess CO2 emitted by humans, is the evil twin sister of global warming. When CO2 disolves in seawater, carbonic acid is formed. Shellfish and coral need calcium carbonite to make their shells. Calcium carbonate is alkaline, the opposite of acid.

Not only do the coral and the shellfish we are familiar with depend on a certain pH level in seawater, so do coccolithophores, tiny plankton that are armored with calcium carbonate shells, just like the more familiar shellfish. Except these little guys are critical to a balance in the carbon cycle, that has supported life as we know it for hundreds of millions of years. And besides that, they are the very bottom of the food chain that all other sea life depends on.

They cannot survive in acidic water, because they can't form their alkaline shells. And they are one of the biggest carbon sinks on earth. Their shells eventually fall to the bottom of the deep sea, locking carbon, in the form of calcium carbonate, out of the carbon cycle, and thereby helping keep the cycle in a balance that has supported life as we know it.

And those "scientific conferences" with hundreds of skeptics? These aren't real scientific conferences, they are propaganda events. They are hosted by right wing propaganda mills like the Heartland Institute and the American Enterprise Institute, who offered $1,000 per speech and $10,000 per manuscript to skeptical scientists. The Heartland Insitute is largley funded by Exxon/Mobile. These are both right wing propaganda mills, and are definitely not scientific organizations
