Why do global warming skeptics ignore modern data?

A frequent argument by global warming skeptics is that the climate has historically changed naturally without human influence. For example, they'll show a graph illustrating the close correlation between climate and Sun over long periods of time in the Earth's history, but won't show the modern data such as this:

http://solar-center.stanford.edu/sun-on-earth/600p...

or this (TSI since 1978):

vs. this (global temp since 1975):

http://tamino.files.wordpress.com/2007/08/t1975.jp...

Of course the climate changed without human influence in the past, because humans didn't have the capability of influencing the climate in the past!

Now we do, and lo and behold, the climate is no longer following changes in the sun, and it's warming at a rate 20 times faster than when the planet naturally comes out of an ice age.

Is it possible to be a global warming skeptic without ignoring modern data?

Update:

Priest - why do you only look at 1998 while ignoring every previous year, 1999, and 2000?

If you look at the trend instead of individual years, the planet continues to warm:

http://tamino.files.wordpress.com/2007/08/t1998.jp...

You can prove anything as long as you cherrypick the data you like. Looking at all the data supports the AGW theory.

Update 2:

Raven - You claim my statement is incorrect, then fail to disprove it.

You talk about the Younger Dryas (a rapid cooling period, not an emergence from an ice age). Okay, well the Younger Dryas was a rapid cooling of about 5°C over 1,000 years. The current warming is 0.5°C over 30 years - over 3 times faster.

http://en.wikipedia.org/wiki/Younger_Dryas

Besides which, simply saying "it changed rapidly" does not address why it changed rapidly. The prevailing theory holds that the Younger Dryas was caused by a significant reduction or shutdown of the North Atlantic thermohaline circulation - a possible result of the current warming. However, nothing so radical is currently happening.

You then claim that similar warming trends have happened 3 times in the past 4,000 years while offering no proof of this. Because it's not true:

http://en.wikipedia.org/wiki/Image:Holocene_Temper...

Update 3:

Matt D - no, a brief weather event in one localized part of the planet says nothing about global warming.

You're basically arguing that global warming isn't happening because Canada got particularly cold one winter. But nobody is disputing that global warming is happening. You can see it right here:

The discussion is about the cause, not the existence of global warming.

    Isn't it amazing how people can completely ignore what a worldwide panel of experts (the IPCC) say about global warming in favor of a link from a right-wing propaganda site which bases its views on one of a handful of eccentric scientists?

    Apparently, the governments of every European country, Australia, and Japan are just completely stupid. Or is it possible that our government is currently driven by agenda-driven right-wing politicians funded by major oil companies?

    Here is the simple truth to global warming.

    A = A thicker atmostphere due to added greenhouse gases means more trapped heat and higher temperatures.

    B = Man is thickening the atmosphere by vaporizing oil, coal, natural gas, and forests.

    C = Given A and B, man is heating up the planet.

    The only question for debate is how much and how quickly we're heating up the planet. And that is a question best resolved by experts, not by the likes of right-wing politicians or Rush Limbaugh.

    I suppose we could point out that the Global warming cult doesn't often point out the fact that at the period of the greatest increase in human industrialization we experienced global cooling..

    Or, of course, that nobody actually knows the rate of prior warming cycles over a period as short as what all this doom and gloom chicken little theories are being based on. Much less any idea about the cause..

    The problem is that the "science" supporting human caused global warming is FAR less credible than that against it. So perhaps before we destroy the global economy and kill untold millions of people in the process.. we might want to actually get some credible, more complete data. Else we're going to end up with what we had 30 years ago when these same people told us we were going into another ice age.

    there is no scientific consensus on what causes the periodic ice ages & interglacial periods only a lot of conjecture & quite a number of tentative theorys. the only thing we know for sure is that they do occur & the current interglacial seems longer than average, probably due to the burning of fossil fuel.

    we do know we can cause global cooling in a number of ways such as through seeding the upper atmosphere with reflective sulfate crystals, fertilizing oceanic plankton with iron which then sinks to the sea bed with the carbon it contains, extracting co2 from the atmosphere & injecting it deep underground.(a pilot plant is currently under construction) but should we? climate models are not accurate enough to fully predict the consequences. would global cooling be worse than warming?

    sea levels are 9 inches higher now than 75 years ago & the world has'nt ended over it.

    try to be objective & dont let your fantasy's cause you to panic. get a life! enjoy the warm weather.

    Your claim that the planet is 'warming 20x faster' than when the planet comes out of an ice age is completely false. Temperatures in the past have changed by as much as 15 degC in 10 years (lookup Younger Dryas for an example).

    Furthermore, ice core data shows that there have been at least three periods in the last 4000 years where the temperature has risen by the 0.6 degC in 100 years (the current rate of warming). In other words, there is no evidence that the current rate of warming is unusual.

    I don't ignore data. With any other scientific theory lets say, general relativity, something is proven false the theory is amended to suit the new data so that the theory is true to all known circumstances. While if you look and there is something that is against global warming, activists jsut shrug it off as an "anamoly" and ignore it. An example would be that it is supposed to be the coldest winter in 15 years up here in Canada. If global warming were true, would it not be impossible for it to go colder? Or will this jsut be shrugged off as an anamoly, and all other facts should be observed?

    Isn't it the IPCC the one ignoring the 'data'?

    When this list of scientists attempted to present new data - the IPCC blackballed them:

    http://www.nationalpost.com/news/story.html?id=164...

    U.N. Blackballs International Scientists from Climate Change Conference

    http://www.heartland.org/Article.cfm?artId=22401

    "The scientists, citing pivotal evidence on climate change published in peer-reviewed journals, have expressed their opposition to the UN's alarmist theory of anthropogenic global warming. As the debate on man-made global warming has been heating up, the UN has tried to freeze out the scientists and new evidence, summarily dismissing them with the claim "the science is settled.""

    Wow typical logic from a twisted mind =

    A = A thicker atmostphere due to added greenhouse gases means more trapped heat and higher temperatures.

    A thicker clouded atmosphere won't ALLOW HEAT to ENTER!

    "Some rather listen to pundits and loudmouths and idiots than listen to science. It plays to their stupidity."

    Indeed, especially that guy who said you must be a fun conversation at parties!

    But to clear all dumb airheads, when a guy like me at parties, I discuss a different thing, when I'm in a professional discussion, I discuss more scientific and logical matters.

    and to Answer the global warming problem, well, some scientists tend to not worry or ignore these problems, because the factors causing global warming also tend to cool the environment in some way. I will post more of these research in a while.

    ADDTL: It has been a recent research that some sulfuric gases in the air tend to block the UV rays that makes the environment warmer within the atmosphere. Thus while greenhouse gases traps the heat, some other pollutant gases present in the air prevents warm heat from entering our atmosphere.

    Because the modern data is faulty and skewed (Michael Moorish) to fit the model that they want to represent.

    Source(s): common sense!

    That's why you called them skeptics.
