    A research team confirms that 97 percent of climate scientists agree that climate change is caused by humans.
    What's important is that this is not just one study -- it's the consensus of multiple studies. This consistency across studies contrasts with the language used by climate change doubters.
    Environmental Research Letters published the paper this week. In it, the team lays out what they call "consensus on consensus" and draws from seven independent consensus studies by the co-authors. This includes a study from 2013, in which the researchers surveyed more than 11,000 abstracts and found most scientists agree that humans are causing climate change. Through this new collaboration, multiple consensus researchers -- and their data gathered from different approaches -- lead to essentially the same conclusion.

    This isn't just a "consensus," it's a proof that the experts involved actually do have a consensus that there is consensus; a meta-consensus if you will.

    Good stuff.

    That's just plain silly. The climate has gone through warm and cold periods many times. During cold periods, so much water is locked up in glaciers and the polar ice caps, that sea level drops so low that shorelines extend 20km or more from their current location. And the opposite happens: during a warming cycle, ALL of the ice on earth melts, raising sea level by as much as 100m.

    Most of Earth's cities were built on the shores of lakes, rivers and oceans, because at that time boats were the most efficient form of transportation. All of these cities will be underwater within a few centuries.

    Not to mention Florida and the Maldives.

    Or, the glaciers return and cities like New York will indeed be under water, but that water will be in the form of ice, one mile deep.

    The last time anything like the warm cycle you're talking about happened there wasn't any civilization, and there weren't darn near 7 billion humans living on the Earth. In fact, the last time the sea rose as much as it's poised to now, there weren't any humans on Earth at all.

    Also, "nature did it too" isn't a very rigorous argument; it's avoiding the point, which is that this time, we are doing it. And if we choose, we can therefore stop it.

    To top it all off, I see nothing in your argument that addresses the OP.

    So we should just sit on our hands and watch it happen? Because nature did it when there was no human race? I'm sorry I'm not following your argument at all; the subject here is that it's happening, and it's not natural. That is all.

    Get back to us when you have some peer-reviewed papers to share. For now I'm going with the scientific experts, since we're talking about, you know, science. Not biased politically motivated sources like these. I can find just as many oppositely politically motivated sources; I'm not going with them, either. That's just a slanging match.

    That's true. Billions of years ago it was much warmer. (Of course there was also no oxygen, which would be a bummer.)
    Yep. And this time we are causing it, at a faster rate than ever before.

    Also
    The earth was warmer 100ka, 300ka, 400ka, and 600ka, and most inter-glacials before then.
    And, we were around for all of them.

    but, we're special?

    Homo Sapiens has only been around for less than 200,000 years, so that would be kinda hard, and it was in Africa.

    It's also worth pointing out that the peak of the last interglacial was 3K above baseline, and at the rate we're going we're going to surpass that easily. The Paris agreements won't hold temperature rise to 3K.

    As noted above, there weren't going on 7 billion of us, and we didn't have a whole civilization to protect.

    This human caused one is apparently going to be different. It's apparently going to hit a lot faster, is the main difference (currently about ten times as fast as the next fastest measured, with a greater chance of accelerating than decelerating), which has all kinds of consequences,

    but in addition: it's going to be in a different part of the orbital/sunlight cycle (greenhouse gas causation entirely, which changes the latitude distribution and other features of the warming) it's possibly going to be larger, it's hitting in a time when the normal responses of land organisms - migration, etc - are more difficult due to human alteration of the landscape, and it's mode of causation has speeded up what were in the past long delayed effects such as ocean acidification.

    Again: it's the rate. The acidification boost rate alone, mechanically dependent on the CO2 concentration and nothing else, is going to do serious harm.

    A question: Is it possible to store the atmospheric CO2(of high density) with another gas(low density) in deep rock level of earth ? and by using perfect membrane can we release O2 to atmosphere again from it to solve problem ?

    March temperature smashes 100-year global record
    Average global temperature was 1.07C hotter – beating last month’s previous record increase.


    The global temperature in March has shattered a century-long record and by the greatest margin yet seen for any month.

    February was far above the long-term average globally, driven largely by climate change, and was described by scientists as a “shocker” and signalling “a kind of climate emergency”. But data released by the Japan Meteorological Agency (JMA) shows that March was even hotter.

    Compared with the 20th-century average, March was 1.07C hotter across the globe, according to the JMA figures, while February was 1.04C higher. The JMA measurements go back to 1891 and show that every one of the past 11 months has been the hottest ever recorded for that month.

    Now what ; pad ?
