We just can't prove definitively the cause. Some say it's increase carbon footprint, others say the natural cycle. I don't know..... but the weather does seem to be changing. This is what National geographic says. ......
The Planet Is Heating Up—and Fast
Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years.

We call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place. As the Earth spins each day, the new heat swirls with it, picking up moisture over the oceans, rising here, settling there. It's changing the rhythms of climate that all living things have come to rely upon.
What will we do to slow this warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the face of the Earth as we know it—coasts, forests, farms and snow-capped mountains—hangs in the balance.

Global Warming is bull
this is a quote from Bobby Webster..."That mankind is causing global warming is far from being a proven fact. It is true that records show that average temperatures have increased over this century; however, temperatures actually dropped slightly between the 1930s and the 1970s. This was not associated with a reduction in fossil fuel emissions - in fact, they were increasing over this period. If the 'greenhouse gases' are responsible for global warming, how can this be?Accurate records simply do not cover a long enough period to be useful. The earth's average temperature varies naturally through time, and we so far have few or no good explanations to explain events such as the ice ages. Indeed, there was a 'mini-ice age' around four hundred years ago, during which the Thames in London repeatedly froze over during winter; this was followed by an intensive but natural period of 'global warming'. We do not have enough information to say that current trends are not simply natural variation."
How do we explain this?

Global Warming Debate
I'm curious to what the general public believes about global warming. There are two sides, one says this is the normal cycle of the earth, and that the temperature has risen before.
The other says no, it's the fossil fuels we burn....... what do you have to say.?
