(Barbarian assures deniers that the sky isn't falling)
Really! There is a bump on my head, others also have bumps on their head... the sky is falling!
Perfect denier logic. That's why you guys fall for those stories in the first place.
There can be no other explanation, can there?
Instead of listening to foolish stories, why not just learn about the issue for yourself? Thinking for yourself might be scarey at first, but eventually you'll be a lot better off.
Climate on the Earth has been changing for 4 billion years.
Lately, it's been changing in some very unusual ways.
As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming.

As usual, there's a reason for it. Turns out, greatly increasing the carbon dioxide level the way we've been doing it, traps more heat in the atmosphere.
further if you look at the charts of warming/cooling over last few decades you will find low correlation to co2 lvls
Show us your numbers. What is the correlation? If you were just talking, and never actually did a correlation, then maybe we can see what the data actually show:
So what's that? Simple, really. The oceans have a much, much higher specific heat than the continents or the atmosphere. So most of the heat from global warming is going into the oceans. That's why we see so many destructive effects this early, related to oceans, like stronger storms and rapid melting of the Antarctic ice at the margin of the continent. The heat from atmospheric CO2 is accountable for the warming of the seas as well as the warming of the atmosphere.
but high correlation to insolation/solar activity:
Well, let's take a look...

I dunno, Phil; that looks like a pretty big disconnect to me. Just saying...
Oh but who woulda thought CLIMATE might be influenced by that little yellow thing in the sky..... nah must be humans...
As you can see by the graph, insolation has an effect on the atmosphere. What's troubling, is that we've been able to override that effect. We're just coming out of a deep sunspot minimum. Things should be getting a lot colder (look at the solar energy curve on the graph). And yet, it's getting hotter. That's the issue.
the science is settled: the Sky is falling!
Calm yourself. Start learning about the issue, and stop believing every story a denier tells you. Then you'll be free and you won't have to worry about falling skies.
