Uhuh. You forgot to post your source. Don't want to be caught stealing someone else's research. :)
Arctic sea ice enters the spring melt season « Arctic Sea Ice News and Analysis

Here's some stuff, too:
Arctic sea ice loss unprecedented in 1,450 years - Technology & Science - CBC News

Ice loss minimal in Antarctica, Greenland, and Himalayas - Wry Heat

But loss is still loss and this may just be a temporary slowing of the loss. It still doesn't indicate anything about the warming period stopping any time.

Bering Sea Ice Extent Breaks Records

The Arctic has crossed the threshold from winter into spring. Scientists at the National Snow and Ice Data Center announced last week that Arctic sea ice reached its maximum extent on March 18 and is slowly beginning its summer retreat.

Uhuh. You forgot to post your source. Don't want to be caught stealing someone else's research. :)

Before the industrial revolution, the CO2 content in the air remained quite steady for thousands of years. Natural CO2 is not static, however. It is generated by natural processes, and absorbed by others.

As you can see in Figure 1, natural land and ocean carbon remains roughly in balance and have done so for a long time – and we know this because we can measure historic levels of CO2 in the atmosphere both directly (in ice cores) and indirectly (through proxies).



Figure 1: Global carbon cycle. Numbers represent flux of carbon dioxide in gigatons (Source: Figure 7.3, IPCC AR4).

But consider what happens when more CO2 is released from outside of the natural carbon cycle – by burning fossil fuels. Although our output of 29 gigatons of CO2 is tiny compared to the 750 gigatons moving through the carbon cycle each year, it adds up because the land and ocean cannot absorb all of the extra CO2. About 40% of this additional CO2 is absorbed. The rest remains in the atmosphere, and as a consequence, atmospheric CO2 is at its highest level in 15 to 20 million years (Tripati 2009). (A natural change of 100ppm normally takes 5,000 to 20,000 years. The recent increase of 100ppm has taken just 120 years).

Human CO2 emissions upset the natural balance of the carbon cycle. Man-made CO2 in the atmosphere has increased by a third since the pre-industrial era, creating an artificial forcing of global temperatures which is warming the planet. While fossil-fuel derived CO2 is a very small component of the global carbon cycle, the extra CO2 is cumulative because the natural carbon exchange cannot absorb all the additional CO2.
How do human CO2 emissions compare to natural CO2 emissions?

EVERYTHING you are bringing up right now all hinges on IPCC bull**** so either **** or get the **** off the pot.

Show the peer reviews quantifying everything you are trying to say is quantifiable and you'll get a nod of approval from me.

I did. You never read what you posted which BTW wasn't peer reviews. It was a blog.

Post some peer reviews. Come on Les, you can do it..... or can you?

Is it a review system comparable to real science? Nope

Sure it is. They examine the literature available, which real scientists do when they publish new results. Real scientists also publish review articles, and they don't come close to the level of discussion in an IPCC review.

You're just blatantly ignorant about what real science is, and what the IPCC does. That much is clear. The best example of your ignorance is your reference to a NASA study on jet contrails and the effect on global warming. When I showed you what their results meant with math, you immediately changed your tune about the validity of the findings. Poor math challenged Petros...

I can see why you don't actually read the papers you refer to. It's very inconvenient when it doesn't support your outlandish claims.

What lead to this statement Tonington?

"All the responsible people are aware of this weakness in the fourth
assessment. All are aware of the mistakes made," he said. "If it had not been
the focus of so much public opinion, we would have said 'we will do better next
time'. It is clear now that working group II has to be restructured."

What lead to this statement Tonington?

A failure of quality control in the review process. Working Group II, assessing socio-economic factors, impacts, and adaptations does not have nearly as much literature to review, as the impacts are only now becoming significant enough to rise above simple noise. The authors of that group should not have published that very specific claim.

Real science misses stuff like this too. If you'd like I can point you to a blog that documents such mistakes across all fields of science:
Retraction Watch

I never said IPCC is perfect...far from it. But, it does have a more thorough review process than submitting a paper to a journal. Did you know some journals allow you to pick your reviewers? The model of Elsevier and Wiley and Sons where you pay ludicrous amounts for subscriptions is failing, and I say good riddance. I welcome open-access.
