climate change over a million years is a natural gradual unstoppable process that life can adapt to

climate change over fifty years is a sudden brutal extinction event whose effect is already obvious to the scientific community and those of us who don’t have a can of scotchguard stuffed up our nose

The rapidly changing climate reshaped the landscape, leaving once plentiful food and water resources in scarce supply and placing enormous pressure on early humans to adapt.

The sustained upheaval drove some species to the brink of extinction, while other better-suited relatives emerged and flourished, the scientists believe.

Researchers identified several extreme shifts in climate dating back millions of years to when humans were first emerging on the continent. Three of the greatest periods of climatic change took place around 2.5m, 1.5m and 1m years ago. These roughly coincide with the appearance of Homo habilis, the first human species; Australopithecus afarensis, a sturdy primitive ape, and the later human species, Homo erectus, which became adept at stone tool use and hunting.

Researchers led by Mark Maslin, director of the Environment Institute at University College London, conducted geological surveys of ancient lakes throughout eastern Africa. They found evidence that over the past 3m years, giant lakes up to 300 metres deep formed and then vanished with the changing climate. The disappearances of the lakes were followed by periods of extreme drought.

Early man must have had a love/hate relationship with the Hummer as well.

Crush GW!

from wikipedia:

The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanoes produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

who cares what happened in iowa man

it probably got colder in your apartment this year too quick fire up a chain email let’s all buy hummers and smoke cigars made of CFCs

Here are some facts to get in the way of your mission.
From the NOAA:

Temperature Highlights – October
The average October temperature of 50.8°F was 4.0°F below the 20th Century average and ranked as the 3rd coolest based on preliminary data.
For the nation as a whole, it was the third coolest October on record. The month was marked by an active weather pattern that reinforced unseasonably cold air behind a series of cold fronts. Temperatures were below normal in eight of the nation’s nine climate regions, and of the nine, five were much below normal. Only the Southeast climate region had near normal temperatures for October.
Statewide temperatures coincided with the regional values as all but six states had below normal temperatures. Oklahoma had its coolest October on record and ten other states had their top five coolest such months.
Florida was the only state to have an above normal temperature average in October. It was the sixth consecutive month that the Florida’s temperature was above normal, resulting in the third warmest such period (May-October).
The three-month period (August-October) was the coolest on record for three states: Nebraska, Kansas, and Oklahoma. Five other states had top five cool periods: Missouri (2nd), Iowa (3rd) , Arkansas (5th) , Illinois (5th) and South Dakota (5th) . Every climate division in Kansas (nine) and Nebraska (eight) recorded a record cool such period.
