The Arctic has become warmer by 5 degrees. Australia has snowed.

I think you're correct.It's how much of carbon dioxide is produced in order to satisfy your personal lifestyle goals and ambitions.
While the graphs of increased Co2 emissions are pretty convincing I remember reading that human activity only accounts for 0.03 (or 0.003) in increase of all greenhouse gasses having impact on the climate. Don't quote me on that though.
I think it's a belief issue. I choose to believe that even if our own activity is the reason of a climate related future doom there is nothing we can do about it so let the orchestra play as long as we are sinking. And if not , there are will be other doomsday scenarios to face-plenty of them .

Humans are responsible for almost all GHG emissions.

There are large methane hydrate deposits at the bottom the oceans, and methane locked up in the tundra but these are breaking down as a result of global warming and will simply make the situation worse if that transitions to higher levels.

Keep in mind, it will take about 200 000 years for the CO2 we have emitted to be broken down into carbon and oxygen. See James Lovelock for more information on this - plants play a relatively small/limited role in this cycle.

Biospheres?

Idk.....I just went through a cat 5 (Michael) 10 miles from ground zero , you can certainly tell who was up to code!
I think if you know what your up against it’s not a problem, in the new house we’re building I’ve been going over and above coastal code by a good bit.....only had a gutter fly off, everyone around me had roof,siding/soffit damage or worse.

I mentioned this in another thread. There has been a sudden shift in the axis of the Earth. It happened around 2006. Google this issue and you will see Youtube videos of Inuit talking about it. NASA denies it.

Well, that takes the biscuit for truly daft! Made me laugh though...

Nah , water vapor is 95% , C02 is 3.6% and the rest 1.4% .
The climate change lobby estimates that 47% of C02 is man made. The deniers deny it somewhat so the impact of humans is at best 1.7% and can be half or 1/3 or whatever. Am I missing something ?

 

[mountainman bob]

The seasons do seem to have shifted by about a month early, we might still be on axis but something is definately askew.

 

[Aridace]

With this type of discussion, its best to put aside judgement and just talk about the numbers - that's all.

That we pump 40 billion tons of CO2 into the atmosphere every year (and have done so every year for the last 30 or 40 +- a few billion either way) should not in anyway be in dispute. Total cumulative emissions from 1870 (estimated) = 2.5 trillion tons.

With the number of discovered self-amplifying loops (positive feedback like warming Arctic ---> clathrate decomposition ---> methane release ---> more warming) still increasing, the amount of atmospheric GHG is likely to increase further than predicted by the models: an increase that eventually could become self-sustaining IOW independent of human action.

I think that’s the whole fix it now or it’s too late concept

With water vapour the Albedo increases and it’s highly localised. It it is entirely natural and the Earths temperature regulation mechanism has evolved to deL with it. Not so anthropogenic GHG.

Shifting Seasons - Conservation in a Changing Climate

Humans are altering seasonal climate cycles worldwide

I’ve noticed it primarily in bird migration patterns, secondly plant and tree growth patterns, thirdly just a uneasy feeling of our natural state.

The is no fix in sight, not even a glimpse, except for feel good measures which are BTW financed by and built with fossil technology.
If necessary the coastal habitats will have to be moved and communities repatriated and migration tackled.
I'm visiting New Orleans quite often and see that the water front properties are being constantly rebuilt over and over again with insurance money meaning often tax payers money. Why ?

 

[mountainman bob]

You know I always questioned the intelligence of a coastal community that built itself below sea level? And then to continue to shovel against the tide over and over?

Ok , I will take the explanation that that max 0.017 change cumulatively is the cause of temperature increase.
The deniers in scientific community say that it won't cause any significant changes in this century and certainly not in the 10-12 years though.

I've asked this on other thread (closed) with similar topic but didn't see any list and I still don't see any on this thread. Perhaps that's because humans cannot change / control the global climate even if we want to.

 

[mountainman bob]

I'd think we could certainly not contribute to it with such gusto.
But it boils down to the almighty buck.

 

[limono]

Petrobuck , without that "petro" in front of the buck it is far from almighty

The present economic constraints make a fix impossible. A situation already known by the late Harry Belafonte, in the song "there's a whole in the bucket":

To envisage how much the 2.5 trillion tons of CO2 is (the amount we’ve pumped into the atmosphere since 1870), imagine a cube 10.8 km x 10.8 km x 10.8 km.

 

[mountainman bob]

One at a time isn't gonna do it, treehuggers driving hybrids will only do so much...it would have to be mandated across the board, even then most people could not afford upgrading to energy efficiency.
I know I need a 3/4 ton 4x4 to do business.....i can't imagine what a electric version of that would cost.
And even then unless we get a handle on clean electricity it's not gonna matter either.....we're basically screwed.
