It is cyclical. Do you know why we refer to the last ice age as “the last ice age?” It is because there have been many ice ages. In between the ice ages has always been “global warming.” Global warming has always been there. It is not man made.
How about some of you Global Warming believers explaining the Holocene Maximum.We have survived natural cycles like the Holocene Maximum, so you have a point. According to the factors that caused the HM, we’re supposed to be on a cooling cycle. It’s impossible to argue that man has nothing to do with it.Keep in mind that while the Sahara desert was much wetter & greener during the HM, the Midwestern United States was a desert. The nomads of Iowa & Kansas will have to hope the farmers in Africa will send some food…
Wow, the deniers are out in force today! Sadly, their tools are just as blunt as always.We still get variation in weather, because the Earth’s cycles have not changed. When we are tilted away from the sun, that hemisphere gets colder. What has changed is that the overall temperature on average is warmer. And it is continuing to warm. The research now is not about whether it is happening, but what the various implications are, and what we can do about it.Some of the posters above claim that the simulations are not trustworthy. Well, it’s true they have not been as accurate in past years: they consistently UNDERESTIMATED the amount of warming. It’s even worse than we thought.Some want to believe that this is all just natural cycles. No, because the natural cycle right now would be taking us away from warmth. Something else is happening.Actual climate scientists are in overwhelming agreement on the evidence — not “belief,” but scientific judgment. Warming is occurring, and it is 95% certain that it is primarily human-caused.Of course we can influence the Earth. There are seven billion human beings. You can see the “Asian brown cloud” from orbit. There is a giant island of trash in the Pacific. Some people now think the cold period that took place in the 1600s was due to reforestation after ~90% of the Native American population was wiped out by disease (also the reason the Pilgrims’ pitiful colony took hold – they took over developed lands). The data are overwhelming, for anyone who wishes to look at it. We probably won’t be wiped out (barring a runaway warming like Venus), but our civilization certainly can be.
For those who care about looking at real science, here is a link to an article by Jinlun Zhang:+http://journals.ametsoc.org/doi/abs/10.1175/JCLI4136.1+And here is the abstract:+“Estimates of sea ice extent based on satellite observations show an increasing Antarctic sea ice cover from 1979 to 2004 even though in situ observations show a prevailing warming trend in both the atmosphere and the ocean. This riddle is explored here using a global multicategory thickness and enthalpy distribution sea ice model coupled to an ocean model. Forced by the NCEP–NCAR reanalysis data, the model simulates an increase of 0.20 × 1012 m3 yr−1 (1.0% yr−1) in total Antarctic sea ice volume and 0.084 × 1012 m2 yr−1 (0.6% yr−1) in sea ice extent from 1979 to 2004 when the satellite observations show an increase of 0.027 × 1012 m2 yr−1 (0.2% yr−1) in sea ice extent during the same period. The model shows that an increase in surface air temperature and downward longwave radiation results in an increase in the upper-ocean temperature and a decrease in sea ice growth, leading to a decrease in salt rejection from ice, in the upper-ocean salinity, and in the upper-ocean density. The reduced salt rejection and upper-ocean density and the enhanced thermohaline stratification tend to suppress convective overturning, leading to a decrease in the upward ocean heat transport and the ocean heat flux available to melt sea ice. The ice melting from ocean heat flux decreases faster than the ice growth does in the weakly stratified Southern Ocean, leading to an increase in the net ice production and hence an increase in ice mass. This mechanism is the main reason why the Antarctic sea ice has increased in spite of warming conditions both above and below during the period 1979–2004 and the extended period 1948–2004.”
The amount of ignorance displayed by the conservatives on this forum is absolutely staggering. This information is available on the internet, people. Climate change is not a partisan issue. It’s the facts, as measured, on the ground.
Did anyone hear about the THE FOX NEWS person who laughed at the Antarctic Expedition for going there in the winter and getting caught in ice. He is ignorant of the fact it is summer in the southern hemisphere and sea ice and other information is exactly why they were there.
“Deniers” don’t have “blunt points” so much as pointy little heads. It has been called “anthropogenic CLIMATE CHANGE” since the mid-1950’s with proofs supporting the facts in northern Europe’s cooling due to coal use, and North African and southern Europe’s HEATING due to overgrazing, over harvesting of forests, and other HUMAN CAUSED damage to the land and the atmosphere in a complex issue. Thousands of studies since have proven that while international environmental efforts with laws and regulations, the picture has changed, but the end product is the same, Humans ARE causing massive change, world-wide, and it ain’t pretty!
BTW, the change in sea ice movement IS the result of WARMING and changing currents, along with other related factors.
Antarctic sea ice has been increasing lately. You might think that increased ice is caused by increased cold, and so if antarctic sea ice is increasing that must mean that the antarctic is getting colder. But as it happens, measurements on site of the temperature show that the water and air temperature is rising, not falling. So the question is, Why is there more ice even though the temperature is rising? There are several different possible explanations — I posted one above, which has to do with heat exchange in the water. There are some other possibilities. But the central point here is that the increase in sea ice does not mean that it’s getting colder. In fact, it’s getting warmer. That’s not a deduction, that’s a measurement.
Um, no, he didn’t. The only reason Lysenko got any traction was because he had Stalin backing him for political reasons (because Darwinian evolution conflicted with Marxist dogma). And AGW predictions ARE coming true. Where have you been?
mrs1wing: It is global warming because those great temperature storage, the oceans, are getting warmer and at an increasing rate. It is global warming because arctic sea ice is dwindling causing whole villages to erode into the Arctic Oceans because they don’t have sea ice to protect them. Sure, shifting sea ice can trap ships, remember the Shackleton expedition, a century ago. Stop confusing weather and climate. They work on totally different time scales.
These environmental “scientists” stuck in the Antarctic ice used fossil fuels to power their ship and more fossil fuels were burned for the helicopters to rescue them, yet, these same “scientists” expect ME to lower my carbon footprint. Hypocrisy, thy name is Liberal.
^Hmm “deliberately leave out”?? Noting on various news outlets in recent days they’re touting the “record cold”, as it’s after Dec..22 and therefore Winter in the northern hemisphere, but not a word about the record HIGH temperatures on the west coast and Pacific Northwest this year. Yes, they do indeed leave out what debunks the “denier” position. Which, btw, is “evidence” if not a “proof” that finding “politically liberal” networks is a rare thing. MSNBC yes, “NBC” news division, not so much. ABC, conservative Disneyland fantasy, CBS, corporate control by far supports the fossil fuel industry rather than conservation, or selling alternatives NOT also owned by those same corporations pushing oil and natural gas.

global warming…tee hee, tee hee

It also means the hot AND cold temperature extremes are increasing over time.

Why do extreme environmentalists take any natural phenomenon as evidence for global warming? “Warmer? Global warming!” “Colder? Global warming!”

The human race will do what it always does; adapt! We don’t need the help of politicians or eco people to adapt, nature does it for us.
