IEA Warns of Irreversible Climate Change In 5 Years
iONiUM writes "As a follow up to the previous slashdot story, there has been a new release by the International Energy Agency indicating that within 5 years we will have irreversible climate change. According to the IEA, 'There are few signs that the urgently needed change in direction in global energy trends is under way. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high. Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400bn (£250.7bn).'"
As 60% of the energy usage is all the third-world countries, the answer is obvious.
is it that bad seein a hot chick again? if i see a hot chick walkin down the hall i dont say "repost"
Due to massive reduction programs, most of the world keeps CO2 at most slightly increasing, and in some cases lowering. Except for China who's doubling their pollution every ten years.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
I don't expect changes to be made. Capitalistic culture has no thought of the future; people are selfish and will sacrifice their descendants to make things just a bit easier and more profitable to themselves.
I'm kind of curious to see how the world will end up by the time I die.
There will be irreversible climate change. The corporate powers that profit from the status quo have more than enough money to continue confusing the issue for centuries to come. Short of a major catastrophe (i.e. millions dead in first world countries), nothing will ever break through the wall of propaganda to awaken the masses.
Cue deniers coming in to lie about how all the world's climatologists are in a conspiracy being funded by Big Solar or whatever.
this will turn into a discussion assigning political blame, and nothing but a lot of hot air will be generated (pun intended)
what should happen:
blame should be set aside, and fixing the problem should be talked about. seed the ocean with iron to create phytoplankton blooms to suck out CO2 and sink to the ocean floor? it has flaws. so strategize some other ideas. yes, some will have anxiety about doing such major ecosystem altering activity when we aren't sure of every infinitesimal outcome... missing the whole goddamn point about what is already happening to the climate. penny wise, pound foolish. it's time for dramatic action, not hand wringing
look: natural, manmade, whatever: obviously the climate is changing, only complete idiots still insist it isn't. so the most compelling, overarching argument is: we have a vested economic interest in keeping our environment the way we are used to it. so we can talk about a price point about what we are willing to invest to keep the thermostat where it should be. so find the price point and fit a plan of action. end of discussion
we are homo sapiens: we don't evolve fur, we kill animals and wear their hides. we don't look for berries, we slash and burn and make the berries grow where we want them. and we don't get used to a hotter earth with more violent storms. we put our hands on the thermostat, and put the earth in the climate zone we like
we are homo sapiens: we don't adapt to the environment, we adapt the environment to us. we aren't fatalistic spineless scatterbrains. this whole climate change topic is really just an engineering problem, with currently not enough engineers working on it, and too many talking heads and other assorted nitwits involved. roll up the sleeves and get to work
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
The Earth's Climate will enter stasis, and stop changing for the first time ever?
Help stamp out iliturcy.
This is the kind of stuff I oppose when I say I'm a skeptic about global warming. The article makes clear that this is a propaganda statement focused on the upcoming climate summit. I want science, not propaganda.
Sure, I accept that CO2 affects the earth's temperature. I understand this equation, and know that it has been accepted science for a hundred years.
But saying that there is a 'point of no return,' a point where massive feedbacks start making the planet vastly hotter than what CO2 could do on its own, where ocean currents stop flowing.......that stretches belief.
The evidence for it is sparse. In fact, there is good evidence to believe the opposite: that each successive ton of CO2 causes a smaller and smaller effect on the earth's climate (see the above equation and consider its implications if you are in doubt). Thus going from 380ppm to 480ppm atmospheric CO2 will have a smaller effect than going from 280ppm to 380ppm.
"First they came for the slanderers and i said nothing."
from the summary :
Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400bn
that dwarfs green subsidies.
Yes, I'm left. You have a problem with that?
If you think China gives one rat's ass what the IEA thinks about 'climate change' you've got more lead and mercury in your brain than a resident of Shenzhen. The only way their CO2 output is going to stop growing is if we apply tariffs. We won't do that, because we like keeping the industry that makes our stuff faaar away from our precious selves.
Funnily enough, China's actually doing a heap more stuff on reducing emissions than most countries, including starting trial emissions trading schemes next year. And their investment in renewable energies is extraordinary. Unfortunately, they're also the largest country in the world and they're industrialising their population at a crazy rate -- so whether they do enough remains to be seen.
But they certainly care a lot more than one rat's ass, and more than a lot of developed countries also.
You got modded troll, but you made me curious, because I seemed to remember hearing these before, too. Doing a google search of "global warming irreversible YYYY" I came up with these:
From 2009, Obama has 4 years to save the world
From 2009, global warming is now irreversible, study says(also discussed on slashdot)
From 2006, The End of the World As We Know It; THE world has already passed the point of no return on global warming.
From 2005, past the point of no return.
Also from 2005, Global warming irreversible.
From 2004, Damage from warming becoming irreversible.
From 1989, We have a 10 year window to fix the problem.
What do you think of that?
"First they came for the slanderers and i said nothing."
Do you realize that it's possible for what you say to be true (and I agree with the general point) AND for it to also be true that humans are capable of altering the environment? Given that, it's also possible that the natural changes wouldn't be so bad, but the human caused changes might end up being very bad for us. So shouldn't we do something to stop the changes we can stop?
The answer to your questions lies not in the direct answer, but the indirect one. To give the answer I have to give a little background.
The Earth's climate has always been changing and it always will. The treehugger notion we could or should stop the climate from changing is great irony - because that would be a bigger imposition on the Earth's ecology than doing nothing. It would introduce a static climate never before seen on Earth - if it were possible - with inevitable and unforeseen consequences. But there are temperature zones the Earth appears not to like, and it transitions through them swiftly - and then stays on one side or another of this zone for a longer time. There are other zones that global average temperature can vary in for a considerable period of time - until it enters this unsavory zone and then rapidly crosses over it again. I'll leave the "why" of this to some philosopher or trained scientist, but it's a useful observed fact without understanding why.
Giving the average global temperature of the 21st century as 0, we reached the peak of the current temperate zone about 5,000 years ago at a level called the Holocene Climatic Optimum at about +1C. This is about 4-8C below the maximum temperature for the last 450K years or so, and there appear to be feedback effects which prevent the temperature from going any higher than that maximum because it hasn't deviated from this pattern for 2.5 million years - longer than humans have been around. There is a climate danger zone at -0.6C and if we enter it the temperature drops quickly to a new range of -5 to -8C for a very long time. Glaciers march and scrape our cities into the sea, owning the land for a hundred thousand years.
Unfortunately for our teeming billions, up until about 300 years ago the temperature had declined from the Holocene Optimum of +1C to -0.6C and was trending down. -0.6C appears to be the upper bound of one of those unsavory zones, and the next stop is -5C which is quite a drastic change. We were on the cusp of transition into the ice, and in fact that period is called the "little ice age". Each time in the last half-million years the average temperature passed below -0.7C it skipped directly over the intervening temperatures and went directly to the lower level - resulting in the die-off of terrestrial animals including humans, glaciation, and other unpleasant effects. The duration of this cold period averages 100,000 years which is likely longer than we could bear it. If it had not been for the warming currently attributed by some to the burning of fossil fuels and its concomitant CO2 discharge, we would likely already be suffering the cold dipping to -5C or more.
Perhaps 6 billion of us would be dead already, or never born - not from the cold, but from the inevitable famine and struggling for resources that it would bring. But that's not the end. 300 years from now there would be only a few million of our seven billions left, if the resulting wars didn't leave the planet uninhabitable entirely. Our entire industrial revolution, sciences and arts these last 200 years? Lost, perhaps forever.
No matter what we do the Earth will not stay habitable to this many humans forever. In the last half-million years we've had only four such periods lasting an average 12,000 years or so. This warm period we now enjoy is not the Earth's normal temperature. And when it's over, it really and truly does appear to be over for a very long time. It will be cold sooner or later. For me and mine, I
Help stamp out iliturcy.
The same thing will happen if we just continue to burn fossil fuels. We can't keep producing them at current rate for much longer. The peak oil problem is likely more urgent than global warming, so an aggressive plan for transition would benefit us either way.
Sure, we have plenty of ideas.
But I see your point. Short term benefits outweigh long term doubts. Since, long term, we're all dead anyway, I can't argue with that.
No, only a couple of crackpots agree on that. Here's a link of global temperature anomalies in tabular format:
http://data.giss.nasa.gov/gistemp/graphs/Fig.A2.txt
Average for 2000-2009 was +0.52
Average for 1990-1999 was +0.31
Average for 1980-1989 was +0.18
Doesn't look like it's getting colder, especially if you consider that every single year since 2000 has been warmer than the 1990-1999 average.
1) The USA's population growth rate is already negative when immigration is ignored. And I'm not talking about the children of first-generation immigrants, I'm talking the immigrants themselves.
2) If you live under the delusion that having children lowers your cost of living, you're sadly mistaken. In spite of deductions for children, a family with kids has a lower standard of living than one without.
3) The US population is such a small part of the world's population that if the US population were 100% removed today, the world population would be higher than today's in five years.
"I do not agree with what you say, but I will defend to the death your right to say it"
When you are talking about tipping points, the point of no return is incredibly obvious. You will see planes falling out of the sky, and ships sinking for no apparent reason as methane clathrates vaporize, disrupting the buoyancy of the water and air above them.
All the more reason to start mining the sea bed--make sure that shit is released as CO2 rather than methane.
