Gee I wonder which one the science board sides with, every climatologist or /pol/.

Climate change is real.

Question is can we do anything bout it anyway?

>>10391324
Yes, emit less greenhouse gasses.

fake news

>>10391321
I don't know what this means but it looks bad. but ok i believe you. At least know a /pol/tard was converted on the issue of climate change just now. Thanks.

>>10391324
And whats the answer to that,... are we past the point of no return?

>>10391311
Yes but too late.

>>10391311
Yes it's real, yes we caused it. Yes we're still fucked, even if we change everything we've been doing now.

I've got another question though, to anyone who wants to weigh in: Is climate change a driving factor in what's happening now with the polar vortex in the northern united states caused by climate change, or not?

>>10391457
climatologists seem to think so
pretty scary imo, these are exactly the kinds of state transitions everybody was worried about triggering

>>10391324
better than saying 'aw fuck it' and doing literally nothing

>>10391311
It’s natural and not caused by humans. Alarmists predictions Are idiocy.

Co2 is minor and a volcano puts out more than every car in the world combined

>>10391311
Everything adds up and particles have properties.

>>10391311
It's real but not manmade

>Is climate change a driving factor in what's happening now with the polar vortex in the northern united states caused by climate change, or not?
This question makes no sense: climate change is a long term, global average phenomenon, you can't say whether a smaller, localised effect is a result of it or not.
It's like if I have a surface and I know its topology and ask if the curvature in some small region is a result of that topology, the answer isn't "yes" or "no": the topology only determines the global structure of the space. For example, a small region of negative curvature could be part of a sphere, even though spheres typically have positive curvature and negative curvature makes you think instead of higher-genus Riemann surfaces. Pseudo-spheres are examples of just this.

If global warming is caused by CO2 then why don't we just plant a fuckload more trees? Try terraforming deserts into forests and all that fancy Dune ecology shit?

Wouldn't enough trees be able to reverse or at least halt it?

>Is climate change real
Yes it's 100% certainly real
>Is climate change exaggerated
No it's not exaggerated and actually increasing at the rate that most experts imply
>Is climate change caused by human activity
Yes we know for certain with more than a thousand correlations that climate change is a direct effect of human activity
>Will the ecosystem collapse in its entirety due to global warming if it continues?
Yes when 3 degrees warming is reached the amazon forest will collapse starting a chain reaction which will cause the arctics to melt and release a lot of trapped methane (worse greenhouse gas than CO2) and warm the world up even more which will result in the release of methane clathrates from the bottom of the ocean to release. This will cause the world to warm by a total of 25 degrees Kelvin. To give you an example of how devastating this is. During a total nuclear war the global temperature will only change 10 degrees kelvin for about 5 years but would still result in 90% of species to go extinct. The global warming will be 25 degrees and be permanent. Every multicellular species will die out
>Will humanity be threatened by global warming
Nope. Humanity won't even notice it.

Why? Because 3 degrees of warming will only be reached by 2125 and it'll take 10,000-50,000 years for the total ecology to collapse and will warm very slowly from the 3 degrees of warming in 2125 AD to the 25 degrees of warming in ~52125 AD. We will have more than enough time to use our science and technology to overcome this problem well before it becomes a threat to human existence.

Nature and the planet are completely fucked though unless humanity cares enough to fix it but I doubt it since most humans prefer urban technological areas anyway, nature is probably going the way of the dodo with the only multi-cellular species that survive being humans and our pets.

We do. Every first world country is planting a fuckload of trees as fast as possible to counter global warming and make them suck up CO2.

>>10392132
i agree

>>10392148
Shit, Australia is doing poorly on that regard.

>goes outside to plant some trees
>emu police lynch me for breaking curfew

That's only the result, not the cause. The cause is the huge amount of people alive on the earth and the rapid growth of people.

Even if humans emitted 0 co2 per person through technology such as cars and electricity, breathing and energy emission through body heat alone would heat up the earth due to the immense amount of people which exists. And this is growing. Humans are literally parasites on the body which is the earth.

>>10392161
>And this is growing

Not for long.

Accept we will not know whether most things are true or false.
All models are wrong, but some are useful

Wrong. Natural selection will inevitably lead to selection pressure for higher fertility preference, eventually reversing the so-called demographic transition.

CO2 is the dominant factor in the current warming trend and humans emit more CO2 in a day than all of the Earth's volcanoes do in a year.

>>10392161
>Even if humans emitted 0 co2 per person through technology such as cars and electricity, breathing and energy emission through body heat alone would heat up the earth due to the immense amount of people which exists.
Body heat is incredibly insignificant compared to other factors that control the climate, even if you ignore that this heat is simply being moved from other energy sources and not being added to the Earth's energy budget. You're being just as disingenuous and retarded as deniers.

You can certainly calculate how much the average increase in global temperatures has contributed to the likelihood of a local event occurring.
