If you had to pick any time in human history in which to live, wouldn’t the end be the best? If you could watch only one football game, wouldn’t you pick the Superbowl? Well I haven’t watched the Superbowl for the last 5 years, but I’ve been closely following how the world may be coming to an end and it’s fascinating.
When I first started this website I predicted that within 50 years at least 1 billion people will have died directly from climate change, and billions of others will have died indirectly. The oceans turn acidic, billions of people starve because farm land becomes desert from rapid evaporation from the increased heat, billions of people living in coastal cities either drown or become environmental refugees from underwater cities, economies collapse, wars break out over limited water and other resources, and that’s why this website is called climate disaster.
Well I was wrong… 50 years is way too much time given how fast we are accelerating towards certain death. My new estimate is under 40 years, that around 2045, billions will be dead.
Some of the articles I’ve read lately, have led me to believe I was being too conservative with my estimate. For example George Monbiot’s recent article:
“Reading a scientific paper on the train this weekend, I found, to my amazement, that my hands were shaking. This has never happened to me before, but nor have I ever read anything like it. Published by a team led by James Hansen at NASA, it suggests that the grim reports issued by the Intergovernmental Panel on Climate Change could be absurdly optimistic(1).
The IPCC predicts that sea levels could rise by as much as 59cm this century(2). Hansen’s paper argues that the slow melting of ice sheets the panel expects doesn’t fit the data. The geological record suggests that ice at the poles does not melt in a gradual and linear fashion, but flips suddenly from one state to another. When temperatures increased to 2-3 degrees above today’s level 3.5 million years ago, sea levels rose not by 59 centimeters but by 25 meters. The ice responded immediately to changes in temperature(3).”
“Rather than taking thousands of years to melt, as the IPCC predicts, Hansen and his team find it ‘implausible’ that the expected warming before 2100 ‘would permit a West Antarctic ice sheet of present size to survive even for a century.’ As well as drowning most of the world’s centers of population, a sudden disintegration could lead to much higher rises in global temperature, because less ice means less heat reflected back into space. The new paper suggests that the temperature could therefore be twice as sensitive to rising greenhouse gases than the IPCC assumes. ‘Civilization developed,’ Hansen writes, ‘during a period of unusual climate stability, the Holocene, now almost 12,000 years in duration. That period is about to end.’(4) - http://www.commondreams.org/archive/2007/07/03/2269/
This is what scientists say is going to happen if we continue business as usual. The surprising thing is that we aren’t continuing business as usual. Instead, we are charging forward, building even more coal plants, third-world countries are following our lead and now building as many coal plants as us, and CO2 emissions are FAR EXCEEDING levels in the 1990s. Not only that but there are signs that the world is starting to experience feedback loops, causing even more emissions and more melting.
More ice is melting, and temperatures are increasing more than anyone predicted in the last couple years. I think this trend will continue, where every year or so we hear about “shocking changes” that scientists can’t explain. The dates might change, but the results are still the same. The human race is doomed, unless we have something like 100% renewable clean energy by 2020, meaning we start making it a reality right now… which is definitely possible, but insanely unlikely in the current political environment. Politicians are going to block renewable energy projects like they have been. Eventually the earth’s atmosphere may change, causing environmental refugees, wars over resources, and massive starvation. The future is very uncertain.
