Global Warming Started 180 Years Ago Near Beginning of Industrial Revolution, Says Study (smh.com.au)
New research led by scientists at the Australian National University's Research School of Earth suggests that humans first started to significantly change the climate in the 1830s, near the beginning of the Industrial Revolution. The findings have been published in the journal Nature, and "were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice cores, tree rings and the changing chemistry of stalagmites in caves." Sydney Morning Herald reports: "Nerilie Abram, another of the lead authors and an associate professor at the Australian National University's Research School of Earth Sciences, said greenhouse gas levels rose from about 280 parts per million in the 1830s to about 295 ppm by the end of that century. They now exceed 400 ppm. Understanding how humans were already altering the composition of the atmosphere through the 19th century means the warming is closer to the 1.5 to 2 degrees target agreed at last year's Paris climate summit than most people realize." "It was one of those moments where science really surprised us," says Abram. "But the results were clear. The climate warming we are witnessing today started about 180 years ago."
The deniers do not care, they will be dead before the worst hits. As long as they can live high on the hog on their imaginary money until they die, they are happy. There is not one drop of concern for the future of humanity or life on earth in general.
anti-science nutters that cannot understand
My irony meter just exploded.
Yes some warming is occurring, but not enough to matter in any way worth even getting excited about - at least that's what the hard facts and careful research tell us.
Funny how the anti-science nutters are always so highly selective about their "hard facts and careful research", hand-waving away all the rest of the data that doesn't fit their own narrative as "manipulated". Let me guess, the whole of the IPCC Working Group II's collected data is all compromised and ignorable, every bit; none of those described impacts could possibly happen, amirite?
Heck it's probably
Ah, another hard fact, with more careful research behind it?
not even enough to counteract the next global cooling phase which is close at hand
It started 8000 years ago, temperatures have been dropping since then - up until we changed everything.
Now the soft facts and panicked revelations made by so called "scientists" who are backed by governments trying to bilk the people into more central control
Now the baseless allegations of conspiracy and paranoia, with the inevitable government agenda behind it. Did you notice all the Australian climate scientists recently protesting their government's agenda?
But of course I forgot, they just want to keep their jobs, and they have to keep manipulating their data and falsifying their results even when their government clearly doesn't want to hear it - low-paying research on global warming is all they can do, because the fossil fuel industry certainly doesn't have any money for them.
isn't it astounding that after literally decades of being utterly wrong about long term climate forecasts, people still listen to them?
Dammit, my brand new irony meter just exploded as well.
Why would anyone engrave "Elbereth"?
That is not a belief. That is fact.
I prefer the "u" in honour as it seems to be missing these days.
And yet that's precisely what the original poster was complaining about. Climate scientists have progressively refined their models over the last few decades as more data became available and as computational power increased to the level that they can run simulations on a desktop that would have needed a supercomputer in the '80s (and far more complex ones on modern supercomputers). When they refine their models and obsolete some of their old predictions (or those of other researchers - there's nothing an academic enjoys more than proving another one wrong) then you grumble about the wrong predictions. When the new models predict some of the same things as the old, then you complain that they're not adapting their hypothesis.
