Official Global Warming thread (merged)

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.

"Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007," the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC.
"So given that fact, you can argue that may be our projection of 2013 is already too conservative."

Good stuff! :)

Wait what? Another blown prediction?

Finagle factor strikes again......change the equation to fit the answer.

It's been said before...but every time I read another one of these articles, it strikes how gullible and/or slow one has to be to continue to buy into the climate change hysteria.

To continue to swallow the finagle factor you mention above is just being willfully ignorant. Can you believe that policy is being made based on predictions just like this one???

With our current administration, yes I absolutely believe it.

Did any of you even read the article? That was a worst case scenario as of 2007, using data up to 2004. He goes on to say:


"In the end, it will just melt away quite suddenly. It might not be as early as 2013 but it will be soon, much earlier than 2040."

The US National Snow and Ice Data Center (NSIDC) collects the observational data on the extent of Arctic sea ice, delivering regular status bulletins. Its research scientist Dr Mark Serreze was asked to give one of the main lectures here at this year's AGU Fall Meeting.

Discussing the possibility for an open Arctic ocean in summer months, he told the meeting: "A few years ago, even I was thinking 2050, 2070, out beyond the year 2100, because that's what our models were telling us. But as we've seen, the models aren't fast enough right now; we are losing ice at a much more rapid rate.

"My thinking on this is that 2030 is not an unreasonable date to be thinking of."


There is no finagle, he was simply saying that even this study may be a conservative estimate since it didn't include data from the record minimum ice extents in the summers of 2005 and 2007. I've personally been to AGU meetings, it's a legit professional organization.
 
Here's what has happened since 2007, in case you were wondering

Arctic sea ice reaches lowest extent for 2013

And here's another interesting related article

Arctic sea ice delusions strike the Mail on Sunday and Telegraph

Antarctic sea ice hit 35-year record high Saturday

Yep, and 3 days later it all froze back......So the Antarctic is setting records and as I read the article more, it sounds like that we are beginning to see more and more ice at the minimum levels. How do you get a complete melt in 20 years?

Good, cheaper shipping and opens up more area for energy exploration.

Agreed, sort of. I am actually in energy exploration. I'm also conservative. I'm not anti-science, however.

This BBC article you all mocked without even reading was concerning Arctic Sea Ice. This article is about Antarctic sea ice. If you're curious about the differences (beyond penguins vs. polar bears) read this

Arctic vs. Antarctica

If you're curious why ANTarctic sea ice has increased in recent years, read this

Is Antarctica losing or gaining ice?

That article is from September. Here is todays data. Looks like plenty of ice to me

That article was from September because that's when the Arctic sea ice reaches it's minimum extent. After September the ice grows again. What's your point?


In breaking news, Alaskan winters are cold
 
and here is the entire year. Whats the problem?

The problem is you are only looking at 2013 and not the long-term trend.

You're trying harder than some people in this thread though, who think global warming is obviously a lie because "it was cold this week"

:no:

Global warming might very well be real, the Earth has gone through many warming and cooling periods through out history without any input from man. We very well may be experiencing a change, I don't think we (humans) are having any affect either way.

This. All day.

I forgot to add;

Instead of ruining economies and hurting people by trying to prevent something we cannot we need to be figuring out how to live with it.

I agree with the parts I've bolded. Obviously natural forcings on climate are going to happen with or without us on this planet. At one point North America was almost entirely covered in a shallow sea. At one point our planet was almost entirely covered in ice (snowball earth). The most well-known climate forcing is by Milankovitch cycles which I'm sure has popped up in this thread. The problem with attributing global warming entirely to Milankovitch cycles is that we should be on a cooling trend for the next 70,000 years or so (the last temperature maximum in the cycle was at the beginning of the Holocene around 10,000 years ago).

Obviously there are other factors that contribute to climate too: the position of landmasses relative to maximum solar irradiance and its effect on our planet's albedo, ocean currents, etc. Our planet is a dynamic system, but to believe we have no impact on it is naive.

Again, I am in the energy exploration field. I am conservative. I don't want ruin my livelihood and I don't particularly care to regulate your hummers. I'm telling you there is no giant conspiracy between scientists and democrats.
