Sun May Be Warming Both Earth and Mars 1050
MCraigW writes "Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes might have a natural — and not a human-induced — cause. Mars, it appears, has also been experiencing milder temperatures in recent years. In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide 'ice caps' near Mars's south pole had been diminishing for three summers in a row. Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun."

"His views are completely at odds with the mainstream scientific opinion," said Colin Wilson, a planetary physicist at England's Oxford University. "And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report."
Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that "the idea just isn't supported by the theory or by the observations."
Perhaps the biggest stumbling block in Abdussamatov's theory is his dismissal of the greenhouse effect, in which atmospheric gases such as carbon dioxide help keep heat trapped near the planet's surface.
To add to this, I'd like to point out that global warming deniers are quick to dismiss 650,000 years of data about earth's temperature as not being representative of the facts, but they jump on 3 years of data (and data confined to a local area and not the whole planet) as evidence against global warming, solely because they think it supports their opinion. If they were serious about science, they would apply the same rigour to the arguments they agree with as to the arguments they disagree with.

Indeed. Because the history of human advancement is one in which every innovation in resource consumption proved ruinously expensive and set humanity back a step, caused endless suffering and waste.
Take for example the move from wood burning to coal energy, which resulted in the reforestation of vast swathes of Europe. Oh, hang on, that was a good thing. Well, how about the rise in urban poverty? What, you're suggesting that conditions, especially with regard to food security and illness, were actually worse in the cities before that? Oh well, forget it then.
But the move to petroleum from coal has been an unmitigated disaster, hasn't it? Oh, okay, right.
Yeah, but the energy conservation measures and emission controls of the 1970s and 80s in California are the shape of things to come. Their disastrous impact on the state left it gutted and rudderless... except they didn't. Wait - what do you mean? Are you saying that every innovation in terms of motive power, energy sources and efficiency has had a net positive effect both economically and by just about every other metric? But we should avoid it at all costs this time, because we're not Cross My Heart and Hope to Die Capital ESS Sure about things?
Because if you are, then I can see why you'd want to avoid that like the plague. It sounds like work.

The good news is that this is one of the issues where you don't have to understand ocean circulation, feedback loops, or satellite calibration. Just look at what's warming up and what isn't. From CO2, you get heat retained at low altitude that would otherwise be radiated into space. Expected result: nights warming relative to days, troposphere warming, stratosphere cooling. From solar forcing, you expect days warming relative to nights, and stratospheric temperature constant or rising.
Anyone who has Google for a second brain can find out, in minutes, which hypothesis matches the data better.

The tendency among activists convinced that the answer to (2) is "yes" is to demand substantially increased government control over our lives, to the point of seriously proposing forced rationing via "carbon credit cards" [bbc.co.uk]. See also here [physorg.com]. (Friends of the Earth reacted to the proposal by saying it wasn't drastic enough.) So, part of the motivation for "arguing against global warming" (on its reality or on the need for action) is that GW is apparently being used, by some, to push a socialist agenda.

This is the only sound science approach. If we're not sure about global warming, we need to check on this. Let's track temperature changes as we remove carbon from the air just as quickly as we've put it in. It is the only way to settle the debate.

Is it possible that the warmer temperatures that Earth is experiencing are caused by cyclical natural phenomena? What about glaciers in Greenland that have been shrinking for 100 years (source: http://www.breitbart.com/news/2006/08/21/06082119
One last thing. Lets say we all buy into the fact that we're causing the climate change through CO2. Regardless of what actions we (America) take, China will still produce more CO2 than anyone because they want to get rich. There's no stopping it.

Bzzzzt, I was ten years old when Armstrong walked on the moon and I do indeed remember the "coming ice age". However, Uri Geller's spoon bending, Eric Von Daniken's chariots of the gods, and oversized red platform shoes were much bigger "fads" in Australia. Most kids that I knew in the '60s & '70s were "breathlessly waiting" to be conscipted to Vietnam and "worried" about nuclear war.
The root source of the "coming ice age" story can be traced back to a National Geographic article, I know of no scientific paper concerning global cooling that was produced in the 70's (see the other posters links).
OTOH: You are talking to a guy who at one time thought he looked good in oversized red platform shoes.
