Al Gore told us that the arctic ice sheet would be gone by 2013, but the Earth now has more sea ice than ever previously recorded. America experiences record low temperatures and record snow falls every year.
The evidence is literally everywhere, but a diminishing percentage of Americans still feel the need to believe in Global Warming--almost religiously. Global Warming Denial has become the heresy of the 21st century, but it's not based in religion or even in science.
Weather is not the same as climate
The most common argument to dismiss these inconvenient truths is that individual events do not represent the overall global climate. While Hurricane Katrina was touted by the Global Warming crowd as irrefutable proof that global warming is real, record low temperatures and massive blizzards are played down as irrelevant--some misdirected souls even try to use these increasingly brutal Winters as evidence of Global Warming!
