*** Official Global Warming Thread ***
I guarantee that our only hope is geoengineering artificial trees and reforestation. Before biofuels and wind/solar/nuclear are up to economic par, we will have used ~80% of the planet's fossil fuels, and global temperatures will skyrocket. You heard it here first, and several decades from now, you'll think back and be like damn that crazy cunt wuf was right.
We're currently at ~.8 degree C above pre-industrial global temperature, and we're stuck with ~1.5C already due to lag effects. Also, pollution byproduct of fuel burning is currently reducing global temperatures by ~1C (smog reflects sunlight). This means that we're actually stuck with ~2.5C.
At some point over the next couple decades, people will wake up due to the arctics being entirely gone and sea level rising due to Greenland and Antarctic ice sheet melting, but corporate interests will spread misinformation with the same gusto seen in the current health care debate.
By this time we will be stuck with ~4C due to atmospheric CO2 levels, and the dramatic increases in GHG output from feedback loops like reduced/eliminated oceanic absorption, reduction of heat reflection by polar ice, permafrost melting, and rain forest deforestation
Scientists claim that 2C is disaster, 4C is omgwtf pandemic, and 6C is mass annihilation and a return atmospheric conditions in which mammals did poorly and reptiles thrived. Data has shown that the smart money is on the worst case scenarios modeled by well understood science being way too vastly conservative. In fact, a huge number of known factors pushing global warming have not currently been modeled by anybody because they do not understand them enough to be able to break them down statistically with a low margin of error, despite the fact that the science shows that they're major factors in global warming.
There is a point of no return. We will not know when we've passed it until decades after passing it, but we have reason to believe that we may have ALREADY passed the point of no return i.e. the entire planet could go carbon neutral overnight, yet the planet would still continue warming due to triggered feedback loops.
Our hope is in R&D of artificial trees being successful enough to be implemented on a large enough scale at some point well beyond crossing the point of no return. We do not yet know whether or not this is even possible.
Another pseudo-hope is in biofuels. Enthusiastic scientists claim that we will be able to manufacture biofuels more cheaply than oil in five years time. I certainly hope so, but if this happens there will no doubt be many obstacles that keep it from becoming the majority source of energy for some time. Many of these factors are the unknown ones that come along with R&D, and other factors are the ones that come from special interests battling against change.
I estimate that peak oil and perhaps peak coal will be well in decline in as little as two decades. What this means is that we will have used the vast majority of fossil fuels available, and what that means is that the amount of CO2 in the atmosphere will be significantly higher than today. Peak fossil fuels will come sooner than expected due to the exponential function and the fact that the global economy is ever increasing at a rapid pace. In fact, it is very likely that we are already in an artificial plateau of peak oil, and sometime in the next decade we will plummet.
The shit is going to hit the fan in our lifetime, and I'm going to laugh my ass off at all the superstitious dumbfuck deniers who wouldn't know a fact if they were butt raped by an encyclopedia
Here is a lecture that doomsayers may find interesting. It's less of a scientist lecturing, more of an activist, but the presented data does not disagree with the science except perhaps only slightly in certain areas. It's overall quite accurate
