Any attempts to engineer the climate are likely to result in "different" climate change, rather than its elimination, new results suggest. Prof Ken Caldeira, of Stanford University, presented research at a major conference on the climate risks and impacts of geoengineering. These techniques have been hailed by some as a quick fix for climate change.

But the impacts of geoengineering on oceans, the water cycle and land environments are hotly debated. They have been discussed at a meeting this week of 12,000 scientists in Vienna. Researchers are familiar with the global cooling effects of volcanic eruptions, seen both historically and even back into the deep past of the rock record. With this in mind, some here at the European Geosciences Union General Assembly ( http://www.egu2015.eu ) have been discussing the possible worldwide consequences of pumping sulphate aerosols into the stratosphere to attempt to reflect sunlight back into space and cool the planet.

    Parent post is modded funny? Bahhh . . . he states my opinion, and I'm not being even marginally funny.

    Let me state this again, for those who haven't heard it already. In 1963, my third grade teacher told all of us kids about the interglacial period that we are enjoying. She explained that at different periods of time, the land that we lived on, the school yard, our entire CITY was buried beneath hundreds of feet of ice. Not once, apparently, but multiple times. Let's say it all together, children: "Interglacial period". It means that when you are old and bouncing little grandchildren on your knees, the climate is likely to be warmer than it is today.

    But, all you younger folk can choose to believe that the alarmists who work for the UN and various governments know what they are talking about. Everyone needs to believe in something, I guess. All heed the warnings of the Prophet, Al Gore.

    The modding here has been particularly bad lately. I've seen lots of perfectly fine comments marked as "Troll", lots of serious comments marked as "Funny", many totally-on-topic comments marked as "Off-topc", and so on.

    I know there were changes earlier about how modding is done and which options are available, but I think there's still a lot of work needed to fix up the modding here. Too often it's just plain bad, which is more harmful than not having any modding at all.

    I think it's time to show who modded each comment, and how they modded it. At least this brings some accountability into the equation. We can see who the bad mods are, and maybe make them think twice before engaging in bad modding.

          The moderation matches the community, as a whole. If it does not match up with your personal reality, that means that you are the problem, not the community. Going against the status quo and not going along with circlejerk groupthink is one thing, but (thankfully) this place is far from an echo chamber and anything that gets modded purely because its "against the status quo" gets fixed pretty quick, so that whatever stays modded down after about a day is because its totally fucking retarded and out of touch with reality.

    No, they're heeding the warnings of a lot of very smart people who have been studying the climate system for a long time.

    From the IPCC AR5 synthesis report: https://www.ipcc.ch/pdf/assessment-report/ar5/syr/AR5_SYR_FINAL_SPM.pdf [www.ipcc.ch]

    Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800,000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century.

    The whole report is worth going through. At least look at the figures! This is good science.

      "have been studying the climate system for a long time."

      Define "a long time". These youngsters have been studying for five years? Or, some of the older people have been studying for twenty years? You call that a "long time"?

      Glacial and interglacial periods are measured in periods of tens and hundreds of thousands of years. MANKIND'S HISTORY only extends back 5000 years or so. Recorded history doesn't even occupy half of one glacial/interglacial period. But - some kid who has been studying for five years claims that he has studied climate change for a long time? Uh-uh - that dog don't hunt. Maybe he has spent a significant part of his lifetime studying, but that ain't a "long time". Empires, kingdoms, and nations rise and fall in the blink of an eye on geological time scales.

      Now - if someone were to go back into time, and plant some recording devices so that we could retrieve the data next year, THEN we might agree that we can study climate change. Plant those devices about ten million years in the past, and they will record a few hundred climate changes. Be sure to plant those devices in many different parts of the world - the Sahara, the Himalayas, the Med, Caribbean, Antarctica - scatter them widely.

      FFS, today we have people arriving at conclusions based on data that doesn't even exist. They pretend that they can extrapolate data tens of thousands of years ago, based on a couple hundred years of recorded history!

      Look at China's history. How many dynastic changes are recorded? Wonder how many of those dynastic changes can be correlated to climactic changes? The word I heard was, ALL OF THEM!!

      The climate is not some static thingamabob that was set to a perfect level, and we've come along and screwed it up. Climate changes, quite naturally, with or without the approval of any of the life forms that inhabit this planet!!

          I never claimed that the scientists have nothing. I'm stating that "climate change" has been politicized. I'm stating that a lot of people stand to profit on selling this concept of climate change. I state clearly that the UN promotes this climate change, which fits like a hand in a glove with their desire to redistribute the wealth of the industrialized nations.

          I am simply not buying into the theory that mankind has changed the environment, to the extent claimed. Oh, yeah, we've CONTRIBUTED to something that we little understand. That is unquestionable.

          Your earlier claim that we've accelerated warming, when the climate should have tilted back the other way. What about that? On what basis does anyone CLAIM to know when the interglacial period was "supposed" to reverse itself? I suppose that you are aware that states such as Wyoming were once rain forests? On the Eurasian land mass, I suppose that the rain forests probably extended all the way up to Krakow and Moscow.

          On what basis do we conclude that the natural course of events wouldn't see those jungles returning to the same latitudes?

          Now, before you hit me with continental drift and all that - the last glacial period was only a couple tens of thousands of years ago. It took MUCH longer than that for the North American land mass to drift where it is from the tropics.

          Long story short: I don't doubt the data being studied. I doubt the ability of those studying the data to arrive at relevant conclusions.

          Yeah, I believe that mankind may be a contributing factor to global warming and/or climate change. I do NOT believe that mankind is causing it. That massive fire that appears to rise in the east, and set in the west each day produces more energy on it's most passive day, than mankind has unleased in all of his history. That ball of fire is the primary regulatory agent in any climate change.

                    Not pretending. So you can get it, all on your own! Yes, it is all coming from rightwing nutjobs taking their talking points from the rightwing press, and do you know why? Because they are not smart enough to figure it out on their own. They cannot be climate scientists because it involves math, and so they go back to third grade in the early 1960's, and deal with hypothetical innuendo, like just "suggesting" that AGW is not real. Well, what if it is? You see, politics is actually a good thing. It is not a brawl where whoever brings the most idiots to a fight wins. It is the rational, realistic, assessment of where we are, as whatever political entity we are, and based on that, a rational debate over what we should do. That is called "policy", which is related to the word "politics". which derives from the Greek "polis" which means city.

                    For you, or anyone as obtuse as you, to suggest that politics is a bad thing, and that it immediately implies ulterior motives, only shows that you have been hornswaggled by Murdock, the Kock brothers, the one percenters who actually do have a financial interest in nothing being done about climate change. But you see, that is not an argument that their objections to climate change are wrong. In fact, it has as much to do with the question as your suggestion that maybe climate change is not real. Many here have pointed out to you that this is a joke. Yeah, maybe. And Al Gore and the scientific community say not, based on data, observation, and, you know, predictive science? Of course it could be wrong! That is not the point at all.

                    I am detecting a powerful disturbance in the force. I am getting it from you, from other oil company shills or patsies, from Gamergate failed-to-launch males and science fiction writers that no one wants to read. The disturbance is the stupid. And the main problem with the stupid is, as stupid usually does, that it does not realize it is stupid. Thus they think they are being oppressed just for having a different opinion. But they are wrong, They are not just different, they are truly stupid. You have made some great progress by acknowledging the fact that all the politicalization of Anthropogenic Global Warming is coming from the right. Follow through. Do some research. Check your sources for conflicts of interests. Ask yourself why some one would want to go against all scientific opinion on a particular subject. Is it because they are a heretic, or is it because they are stupid, or because they have very basis financial interests in the status quo. Yes, all the evil is coming from the heretics. But I don't blame you. I just think you do not know any better. And I am embarrassed for you, that you let yourself be used in such a fashion. So just stop. Comment on things you actually know something about. You have made some great contributions to Soylent News. It would be a shame to destroy your reputation for Exxon. Think about it.

    Yes, but I believe we're supposed to be nearing the end of the current interglacial period, which means that things should have been cooling off already. It's possible that we've put off the ice age a bit, which is probably a good thing for us, but that would be a tough balance to hold. I think the climate scientists are well aware of glaciation cycles and have accounted for that as an expected variation in baseline temperatures, which is why they can say that anthropogenic climate change may have started something like 8-9,000 years ago from clearing land for agriculture. I'm no great fan of the cult of Al Gore, but I'm also pretty sure our activities have *some* effect on the climate, even if it's hard to pin down.

      Good answer.

      I've long been convinced that mankind's most harmful affects on the environment is deforestation. People see the lack of vegetation in a desert as the result of to little moisture. Looking at it from another angle, we can just as easily say that there is little moisture because there is so little vegetation to hold the moisture. Much of the mideast was very fertile, thousands of years ago. Today - much of it is desert. What happened? Well - they cut down the trees, over grazed the pasture lands, and when nothing else could subsist on the drying land, they put goats on the land to finish killing off the vegetation.

      Want to save the earth, as we know it? Plant some trees. World Wide Arbor day! If a tree won't grow where you live, plant some shrubs. If there's not enough moisture for shrubs and bushes, plant some drought resistant grass. Let's turn the world green, with photosynthesis!!

    Let me state this again, for those who haven't heard it already. In 1963, my third grade teacher told all of us kids about the interglacial period that we are enjoying. She explained that at different periods of time, the land that we lived on, the school yard, our entire CITY was buried beneath hundreds of feet of ice. Not once, apparently, but multiple times. Let's say it all together, children: "Interglacial period". It means that when you are old and bouncing little grandchildren on your knees, the climate is likely to be warmer than it is today.

    So you are claiming your understanding of climate science is based on what you learned in third grade over fifty years ago and thus we should disregard anything anyone has learned since?
