| quote: | Twelve-month long drop in world temperatures wipes out a century of warming
Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile -- the list goes on and on.
No more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.
A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to wipe out nearly all the warming recorded over the past 100 years. All in one year's time. For all four sources, it's the single fastest temperature change ever recorded, either up or down.
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.
Let's hope those factors stop fast. Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans -- and most of the crops and animals we depend on -- prefer a temperature closer to 70.
Historically, the warm periods such as the Medieval Climate Optimum were beneficial for civilization. Corresponding cooling events such as the Little Ice Age, though, were uniformly bad news.

i find it hard to totally rely on this information because i have never heard of most of them, and could not easily verify that any of those sources were non-partisan sources of info - i would like to see NASA data or something similar.
assuming that it is accurate, i don't necessarily think it counters the global warming theory. using 365 days as the testing period for whether global warming is actually occuring is just as arbitrary as using one month (global warming is a long term trend and i would hardly count one year as long term for these purposes). Weather is not static and therefore we should expect to see short term warming and cooling trends. but the whole premise of global warming is that on average there earth's temp will trend upward. this does not disprove that we are in a long term warming trend.
If the cooling occurred over a longer period, let's say ten years, then i would see it as more credible. nevertheless, if this short term cooling trend leads to glacial accumulation over alaska, greenland, and antarctica, that's a good thing either way. |

What I think it does demonstrate is how people can react and often overreact to short-term volatility in trends (whatever industry or topic we're talking about). Of course the Earth is in a warming trend! It's been warming since the Ice Age! Yes, I'm being a bit glib.
However, what is undeniable in all of this is that George Bush caused it.:toothless |

haha...george bush doesn't care about sea level rising considering his ranch is 700 ft above sea level. |

| Isn't one of the effects of global warming more extreme seasons? So we'll get colder winters and hotter summers? So that, if true, would explain the colder winters countries are experiencing... |

I dunno--they're all theories. I'd think the effect of global warming is, well...a general and gradual warming of the earth over time due to the continued emission of greenhouse gases and CO2 by humans. I don't know if increased seasonal volatility is part of that theory or not. Frankly, I don't think this story proves anything except that Al Gore is a political opportunist. |

OK, will people FINALLY start listening to what I was saying earlier? Global cooling is inevitable. I said earlier that after 2012 it will become obvious. Our dumb corporate-funded "scientists" know jack about climate change, or about the environment in general. Their plans to "protect" the environment, stop climate change is contradictory and quite absurd. Al Gore is an example of how we humans try to save the planet. Bull. We ignore the main reasons that cause CO2 levels spikes, and try to blame it on something to make people believe they're doing something about it.
In my opinion, the effect of increasing CO2 levels has absolutely minimal effect on global temperature changes, I already stressed that eons ago. CO2 levels only RESPOND to changes, they do not CAUSE the temperature changes. I.e. cutting millions of acres of rainforest every year - CO2 levels go up. CO2 levels went up almost 3 TIMES since 1700s or so, while the temp's only went up by miniscule fractions of degrees (did the temperatures go up 3 times???) ... which doesnt add up.
When CO2 levels went up 10,000 years ago at the end of last Ice Age it wasnt global warming. It was in RESPONSE to warming solar cycle changes, caused by melting ice releasing trapped carbon into the air.
I went over this in details on countless global warming threads on this forum. Quite frankly, I was rebuked and ridiculed. But I know that in the end, global cooling is coming. Because you cant fool solar cycles - the biggest temperature fluctuations factor.

You probably won't find it because most peer reviewed scientific journals will chastise anyone that strays from the Gore-mind-hive... |

I find it funny you assert motivation for objective scientific research is not on scientific inquiry, but political bias. As if the scientists do their work for political gain. Sorry, but politics has no bearing on a scientist testing the chemical composition of ice core samples in Greenland, or other similar types of research. |

| ¨record cold in australia¨...we are also experiencing record heat, and we just got the record for the worst drought in recorded history, and we nearly have the record for the worst flooding we have ever seen! not bad considering its all at the same time? Its called Climate Change for a reason - extreme temperatures hot and cold, storms, cyclones, droughts, desertification, et al. Earths fragile equilibrium has been damaged, every ecosystem on earth has been degraded in some way, these fluctuations in weather will just become more and more pronounced as the equilibrium becomes more and more unbalanced. |
