Of course (real) climate scientists are not sure that *all* the global warming is due to man. Here's what the latest (2014) IPCC says about it:
Climate Change 2014 Synthesis Report
Summary for Policymakers
IPCC, 2014
The evidence for human influence on the climate system has grown since the IPCC Fourth Assessment Report (AR4). It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in GHG concentrations and other anthropogenic forcings together.

It's true that, recently, the oceans have been absorbing CO2. And I didn't say it wasn't. What you are quoting me saying is: "But it is also a gas that dissolves in water and when water increases in temperature, CO2 tends to bubble out of it. This is a fact well known to climate alarmists."
Here is NASA agreeing with me:
The Ocean's Carbon Balance
NASA Earth Observatory website (downloaded 2015)
As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance. But this absorption has a price: these reactions lower the water’s pH, meaning it’s more acidic. And the ocean has its limits. As temperatures rise, carbon dioxide leaks out of the ocean like a glass of root beer going flat on a warm day.

And yes we know that saturation levels of CO2 in water is relative to temperature. So what? Right now the oceans are absorbing, not emitting CO2. In fact they are absorbing the majority of it. What is your point?
... About 10,000 years ago that ice age ended and that the earth has warmed ever since. I would be denying that the earth has warmed? If i were to theorize that the earth were going to continue to warm from natural Climate change, No matter what we do i would be denying? But if we listen to what James Hansen says at about 10:48 "Unless we stop the warming". Now we stop warming by stopping what has been occurring for 25,000 years or just the last 200 years?
The IPCC report is too conservative.
The IPCC report is too conservative.
When I mentioned that warming oceans emit CO2 it was in response to your post, that was responding to a piezoe post, which was about temperatures over the last 25,000 years. Not the last 100 years. And over 25,000 year periods, the amount of CO2 dissolved in the ocean does change due to ocean temperature change. Here's a reminder of where this discussion started:
You really need to cut down on all that weed.
By making this sort of comment, you're severely undermining your message that "we should listen to the climate scientists". Instead you want us to "listen to futurecurrents", LOL.
It's obvious that what you really want us to do is to listen to your political objectives. When a climate scientist says something that has political implications that you like, then you're all in favor of climate science. But only in that situation.
Not at all. The top climatologists think that essentially all of the warming over the last hundred years is due to man. The IPCC is and has been conservative.
Global Warming expedition stopped by sea that was not supposed to be there.

A group of adventurers, sailors, pilots and climate scientists that recently started a journey around the North Pole in an effort to show the lack of ice, has been blocked from further travels by ice.
The Polar Ocean Challenge is taking a two month journey that will see them go from Bristol, Alaska, to Norway, then to Russia through the North East passage, back to Alaska through the North West passage, to Greenland and then ultimately back to Bristol. Their objective, as laid out by their website, was to demonstrate “that the Arctic sea ice coverage shrinks back so far now in the summer months that sea that was permanently locked up now can allow passage through.”
There has been one small hiccup thus-far though: they are currently stuck in Murmansk, Russia because there is too much ice blocking the North East passage the team said didn’t exist in summer months, according to Real Climate Science.
Real Climate Science also provides a graph showing that current Arctic temperatures — despite alarmist claims of the Arctic being hotter than ever — is actually below normal.
