Burning All Fossil Fuels Would Scorch Earth, Says Study (phys.org)

mspohr quotes a report from Phys.Org: A new study published in the Journal Nature Climate Change shows our precarious climate condition: "Using up all known fossil fuel reserves would render Earth even more unlivable than scientists had previously projected, researchers said on Monday. Average temperatures would climb by up to 9.5 degrees Celsius (17 degrees Fahrenheit) -- five times the cap on global warming set at climate talks in Paris in December, they reported. In the Arctic region -- already heating at more than double the global average -- the thermometer would rise an unimaginable 15 C to 20 C." This would make most of Earth uninhabitable to humans (although the dinosaurs seemed to do fine with it 65 million years ago). The report also stated that if fossil fuel trends go unchanged, ten times the 540 billion tons of carbon emitted since the start of industrialization would be reached near the end of the 22nd century. For comparison, "older models had projected that depleting fossil fuel reserves entirely would heat the planet by 4.3 C to 8.4 C. The new study revises this to between 6.4 C and 9.5 C," writes Phys.Org.

    Nope, 'Dino sludge' was a one-shot deal. On the timescales needed for new fossil fuel, the sun will have died to the extent that Earth CO2 levels will have dropped below the level needed to sustain plant life (and thus animal life).

    At the current rate there is no way we would last a single millenium on the current reserves.

    Considering the rate at which new reserves are discovered as it becomes profitable to look for them in more difficult places, it wouldn't surprise me if we could find enough fossil fuels to last a millennium. That would of course make the Earth considerably hotter than this projection.

    Hey, I live in Iceland, where the average January low is -3C and the average July high is 13C. Such warming would make us the new California. Bring it on ;) I own some land, you can start booking your timeshares now.

    It's funny, when you hear people talking about forestry here, they talk about things as if they only apply to our current climate. They plant douglas fir, sitka spruce, etc, trees that can become true giants in the right climate, but insist that they'll stay (comparatively) short and grow slowly because our climate is too cool for their optimal growth. Yes, our current climate, but these are trees that can live for much of a millennium. Heat up the country 4-5 degrees and you've turned the climate into that of coastal Washington / British Columbia where they reach their record heights; we have similar sun, soil, precipitation, summer/winter temperature differences, etc (windier, but that's in large part due to the shortage of trees).

    Iceland once even had redwood forests. Washington/British Columbia species are not going to stay short forever if the climate keeps warming.

    Carbon is a heavy element, and breaks down out of the atmosphere eventually, in any form. If you're really worried about it though, i'd suggest planting fruit trees to end world hunger and lock up some carbon, and buying more plastic building materials to lock up even more carbon out of the atmosphere.

    Stop peddling your bullshit anon:

    They can't explain the mechanism

    Bullshit: http://scied.ucar.edu/carbon-d...

    nor can they explain why Earth was so much colder during times when CO2 concentration was 10 times what it is today.

    Bullshit: https://www.skepticalscience.c...

    They talk out of both sides of their mouths and are bullshitting for money, lots and lots of taxpayer money. Why do they need taxpayer money?

    Bullshit: Fossil fuels recieve considerably more taxpayer money than renewables, and they only reason climate science needs funding is that fossil fuel interests insist on continuously pushing back on scientists recommendations.

    You think there would need to be reports like this if, in the 70s, governments had simply agreed that yes, they do need to reduce and stabilise CO2 production? The only reason climate scientists continually need to prove themselves is because of big oil shills and IDIOTS LIKE YOU who are drinking their koolaid.

    I mean hell you're not even honest enough to use your account.

    Models being too extreme? Hardly.

    Forecast: 1990 IPCC sea level rise predictions vs. actuality
    Forecast: 1988 Hansen temperature predictions vs. actuality (Scenario B was described as most likely)
    Forecast: IPCC temperature predictions vs. actuality vs. contrarian models
    Backtest: IPCC AR1 sea ice loss models vs. actual

    Temperatures are tracking, on long running average, right on what has been forecast. Sea level rise is well on the high end. As it stands, our arctic sea ice models predict significantly less loss than we actually see (we're not very good with sea ice right now, and this is well acknowledged by the IPCC).

    I know there's been this contrarian myth circulating claiming that climate models predicted warming that never occurred. There's a nice, well-referenced debunking of it here.

    Secondly,

    An approximately linear relationship between global warming and cumulative CO2 emissions is known to hold up to 2 EgC emissions on decadal to centennial timescales7, 8, 9, 10, 11; however, in some simple climate models the predicted warming at higher cumulative emissions is less than that predicted by such a linear relationship8. The climate response to five trillion tonnes of carbon

    Every other modeler since Jean-Baptiste Joseph Fourier, and especialy Svante Arrhenius uses logarithmic relationship

    if the quantity of carbonic acid [CO2] increases in geometric progression, the augmentation of the temperature will increase nearly in arithmetic progression.Svante Arrhenius

    These guys are claiming the entire body of Climatological "Settled Science" is wrong and they are just throwing it out there like a bunch of assholes trolling click-bait; at least on Facebook the click-bait trolls give you some side-boob or camel-toed yoga-pants.
