Climate Change

So we have a net change of .75 degrees Celsius over the last 120 years. What would be interesting is if we had this data for the past several thousand years, cause as is, this doesn't particularly scare me.

I like how you made it political in the description.
Twat.

alright for all the fucktards who get there news and knowledge from the internet allow me to educate you a touch on global warming.
1. the earth has gone through 200-300 cycles of heating/cooling, the cycles are not defined periods of time
so we can't get an exact number on how many times it's happened before.
2.These cycles are escalatory, the colder the cold period the warmer the warm period until it
reaches a total ice age which is essentially a reset button back to normal.
3.The dark ages was a cold cycle, it wasn't dark because of the plaugue it was dark because
the average world temperature dropped 10 degrees. If everyone didnt die from the plague
they would have died of starvation.
4.That being said the earth is due for a warm cycle as well as a very interesting other cycle which turns the Sahara into a giant fucking oasis.
5. acts of humans will not make the cycle warmer than it was already going to be, our actions will
only prolong the cycle. everything that is going to happen will happen regardless of what we do.
all we can do is determine it's length.
6. we will not officially enter the warm period for about 90 years because of a temperature/reflection plateau
where the remaining reflective surfaces on earth reach a sort of stasis with incoming light
preventing any real increases for a fair number of years until more ice melts and water evaporates.
7. considering how most of our crops love warmer climates, most of our ocean fishing resources will benefet from the extreme increase in
phytoplankton and oxygen as well as most of africa turning into a giant rain forest.
were going to be pretty much ok. a few commodities will become incredibly expensive like coffee.

uh oh someone mentioned something somewhat controversial, everyone pull out your PhDs

Everyone on FJ is now a scientist or politician.

The earths overall temperature changes in cycles from warm to cold over thousands of years. Having a chart that goes back only 120 years is like flipping a coin twice to have it land on heads both times, the hypothesizing that it will ONLY land on heads.

This is a very small sample of time to say that the earth is heating up due to global warming though. While it is getting warmer in this short period.... I cant be arsed finishing this .......

>Does global warming exist?
Yes, it does. Evidence from centers for meteorology and astrophysics support it.

>In accordance with the planet's natural climate cycle, should we be getting hotter?
Yes, we did have an ice age only 12,000 years ago, after all. We're still "coming out of it".

>Does the Greenhouse Effect exist?
Yes, it's why Venus is way hotter than Mercury despite being much farther from the sun. Venus has an absolute fuckton of chlorofluorocarbons, carbon dioxide, and other dense gases.

>Does human industry contribute to the Greenhouse Effect?
Yes, doubly. By removing forests (which reduce carbon levels in the atmosphere) AND adding more carbon dioxide and chlorofluorocarbons to the atmosphere, we directly inflate the normal quantity of carbon-based gases surrounding our planet.

It's not a question of "Are we affecting the planet?" It's a question of "How much are we affecting the planet?" And that, really, is the most important question of all. If the answer is, "Not very much", then we can go about on our merry way for a few centuries (especially considering that when we have no more oil to burn we'll pretty much need clean energy). If the answer is "A fuckton", then we'd better cut emissions and recycle like no sentient race of hominids ever has before.

Lastly, science is not left. It never has been, it never will be. Neither is it right, up, down, or diagonal. Looking at evidence and extrapolating a conclusion, especially when it concerns the natural world and not any distinctly human matter like starving children in Africa. If you've made your conclusion and, from it, declare, "Gee Congress, we really ought to regulate those corporations to reduce greenhouse emissions!", then is when you become left. Because that's what the left does - regular corporations. The left doesn't wear a white jacket and muddle around in a laboratory running calculations.

now just zoom out a little bit so we can see more than a very small amount of time that is 130 years

The earths climate changes around every 600 years, going through ice age like cold sprees, and painfully hot warm sprees. In the dark ages they believed the wars and death were responsible for such high heats. In the early days of america, they couldn't explain why the rivers were freezing over.
So we aren't any fault in this, the earth does it on its own. It's a natural process.

>Implying that we understand the earth's climate changes

We aren't even sure if temperature fluctuations are a normal thing, we haven't been able to measure them long enough

THANKS OBAMA

This is an example of how people can lie with statistics, if you look at the temperature scale between the low at 1910 and the high at 2010 the difference is only 1.25 degrees.

Oh no! The worlds average temperature has risen by 0.75 degrees over the past 130 years! We're all going to dieeeeeeeeeeeeee
