As Antarctic ice melts, a warning emerges from the past Comments

A study published in Nature Geoscience reveals that global warming that occurred some five million years ago causing sea levels to rise dramatically, possibly as much as by 20 meters. Scientists suggest that Antarctic ice may be more susceptible to warming than previously thought. Continue Reading

    @Philip Ruiz and Chris Snyder and Jack Corry and Stanley Kerns ... The article does show some consideration to at least the strong potential that CO2 cannot be considered the 'strongest' agent of change and other possibilities need greater consideration.

    @Dan and Phillip Noe and Glen ... Another article in this very blog mentions the discovery of 10 new volcanoes in one region alone, then is noted expectations of locating more new volcanoes. The certainly you express as to the source of CO2 should become more open and less fixated on CO2. There is no good link to CO2 and temperature, CO2 is not pollution and does not behave as does Carbon.
    It is not then possible to 'rapidly transit' from 'fossil' fuels, there are no viable alternatives apart from Uranium and that's too expensive for developing nations. Natural and 'fraked' (from coal generally) Gas will be the next fuel in widespread use. Gas is particulate 'freer' than coal in direct use and inexpensive.
    "Today, more than 97 percent of climate scientists agree that 1) we are in a period of unprecedented warming, and 2) the primary cause is excess CO2 generated by human activities."
    That from 100 individuals in agreement generally only 97 would opinion 'conclusively' is hardly a worthwhile statistic making, then also the opinion of 'scientists' is no a substitute for actual Science.

    One has to wonder where some of these papers come from, unless the authors are looking for more grant research money.

    Here is a graph of the Antarctic ice sheet area, using the satellite data. It shows a increase. In spite of the hype that CO2 is reducing ice.

    Dr. Larry Vardiman (scientist and physicist) of the Institue for Creation Research says:

    "One possible scenario may be found in a recent series of articles by Henrik Svensmark and Nigel Marsh, cosmic ray specialists from Denmark, who have shown an indirect connection between galactic cosmic ray (GCR) intensity and global temperature.7,8,9 They are studying the influence of the Sun on the flow of GCR to Earth. The Sun's changing sunspot activity influences the magnetosphere surrounding the Earth permitting more GCR to strike the Earth during high periods of activity.

    When the Sun is active, the intensity of GCR striking the Earth is increased, causing more ionization in the atmosphere, creating more carbon-14, and possibly creating more cloud condensation nuclei (CCN). This increase in CCN, in turn, appears to create more low-level clouds which cool the Earth. When the Sun is quiet the GCR intensity striking the Earth is reduced, allowing the Earth to warm. Svensmark and Marsh have shown a striking statistical correlation between sunspot activity and global cooling and warming over the past 1000 years.

    The recent rise in global temperature may partially be due to current low solar activity supplemented by a recent increase in carbon dioxide concentration measured at Mauna Loa. The connection which still needs further study is the production of CCN and clouds by GCR."

    There is a good deal of science showing that global warming is not mad made. Yes, we still should have pollution controls, as we already do, but not to the extreme because it will unnecessarily hurt business.

    It was a well written article and informative

    This story presents the science of climate change well - CO2 levels are rising rapidly, this is caused by humans, it is raising the temperature, and it will likely cause huge sea level rise over time, among many other challenges.

    But then you've got a nonsense paragraph near the end -
    there is no real scientific debate about the reality of climate change.
    and the idea that we can only adapt is absurd - CO2, and other emissions, are the problem. The more CO2 we emit from burning fossil fuels, the worse it gets.
    We have to do more than adapt, we have to rapidly transition away from fossil fuels. For the sake of future generations and to protect god's creation from our pollution.

    It's time for the conservatives to contact their reps in Congress and insist they work harder to reduce global emissions. Too many are playing "obstructionist" games. They should play when the health and safety of our future generations are at risk.

    Is like I've been saying soon after this global warming issue started.... some is do to man but we've had other periods that didn't at all - what we can do might stall the inevitable, but if this is due to nature, it's going to happen.

    Good article. I didn't know about this. Thanks.

    This article might have been news 20 years ago, but the cautious and timid tone is out of place today, as scientic knowledge about causes and effects of climate change has increased dramatically. Today, more than 97 percent of climate scientists agree that 1) we are in a period of unprecedented warming, and 2) the primary cause is excess CO2 generated by human activities.

    How bad it will become is still not known, but geological records show that massive population extinctions have accompanied past climate changes of this magnitude. Rapid climate change can be triggered by a number of different causes, one of which is CO2 buildup due to volcanic activity. Not this time, however. This time it's us.

    Wow...what a striking conclusion: If it continues to warm, more ice will melt. This passes for cutting edge science?

    Article like this provide ridiculous examples of global warming fear-mongering and shouldn't be featured as a Google science news picks. Antarctic ice is increasing, not melting--a inconvenient fact that is always glossed over by the catastrophists.

    Catholic Online should stick to religion.

    And, how is it that cavemen and their predecessors caused that huge melt off? Is there some chance that the sun might be involved? Possibly Druids could be found to offer the proper sacrifices--or maybe we could learn to accept the fact that we live on a changing Earth--and with modern technology we are better able to become await of those changes. Also, as ice occupies a larger volume (10%) than the liquid water it can become, and in that the weight of the glaciers has depressed the land beneath them to well below sea level, were the ice caps to melt (and Antarctica has been frozen since it separated from South America in the Miocene and the South Circumpolar Current began to flow) were the ice caps to melt the space formerly occupied by the ice would become available for the liquid water it became--and sea level would actually fall.
