It is part of Earth's natural progression until proven otherwise. Global warming alarmists are trying to claim that this is a man-made phenomenon because they can't account for their observations through natural processes. This is EXACTLY opposite of the method traditionally used in science, and hence INVALID.

Alarmist's will also try to distract you from obtaining a fuller understanding of these natural processes by claiming that if we don't take action now, we'll suffer global disaster. It's the same technique a high pressure car salesman will use to get you to buy the car now, instead of thinking about it and possibly buying a different car from a different salesman.

SHORT ANSWER

Historically yes but since the onset of industrialisation human activity has greatly accelerated both global warming and climate change.


LONGER ANSWER

Historically the only factors driving climate change have been natural ones but in the last 200 years human activities have had an increasingly dominant role to play.

Both the Earth and the Sun go through a series of complicated cycles, these last anything from a few years to hundreds of thousands of years. Depending whereabouts we are within these cycles there can be a net warming or a net cooling effect. It's these cycles and the interaction between them that have caused short term warming and cooling and have been the trigger for long term warming and cooling.

Currently there's a short term warming trend which has been warming the planet for 18,000 years, this is an anomoly in an otherwise general cooling trend which has been with us for a little over 50 million years. Odd as it may seem, the long term trend is indeed a cooling one and as the history of the planet goes, it's actually quite cold at the moment.

These natural cycles have been responsible for the coming and going of ice ages and historical warming and cooling. But, and this is the salient point, these changes occur very slowly - over thousands and millions of years; the year on year change in average temperatures is miniscule.

In the last 200 years, and particularly in recent decades, the rate of warming has been infinitely more than anything that could possibly be attributed to natural cycles alone. And it's no great mystery as to what's happening.

So what is happening? The science behind global warming is remarkably simple and has been known about for over 100 years. The planet is naturally insulated by a layer of greenhouse gases without which Earth would be 33°C (59°F) colder than it is. Industrialisation has led to a dramatic increase in the levels of greenhouse gases in the atmopshere which is increasing the Earth's insulative properties. Put simply, the more of these gases there are the warmer it gets. The combined levels of all greenhouse gases are higher now and are rising faster than at any time in known history (we have accurate records stretching back nearly 750,000 years).

The earth has been both much warmer (there was no ice anywhere at the time of the dinosaurs for instance) and much colder in the past. Caused mainly by the sun and earth's distance from it (which changes over time).
The stats show that the earth has warmed up by 1 degree celcius over the past 100 years (though it seems most of that warming actually happened before the second world war).
I used to be totally convinced that global warming was caused entirely by human activities but now I have some room for doubt.
But nevertheless global warming is occuring and it is affecting our weather patterns. And whether humans are causing it or not, we do pump far too much pollution into the world and we do need to clean our acts up.

Could be, depends, scientists are fequently wrong in their predictions so are the doom and gloom mongers. History is full of false predictions whether scientifically based or not.
It was only a month ago that this summer was forcast to be the hottest on record at least according to the media. Lets see at the end of the summer. Incidentally if it isn't the hottest on record or if average global temperature's do not rise by 2 deg C over in the next 20 years or so don't expect anyone to apologise for being wrong

no it absolutely is not. the ice age had many reasons for occuring. as we can see natural disasters and climate progression has increased every year since the industrial revolution. which absolutely makes sense since during the industrial revolution there was pollution like never seen before and the advent of affordable automobiles. basically right now many of us dont live as responsible citizens and take the care and concern of the environment into our everyday lives but there are certainly many things that can be done to limit and even if we care enough reduce the effects of global warming on the world.

Climate has changed many times in the past, most often due to the sun.

But science has proven (as much as science is ever proven) that, this time, the warming is mostly caused by us.

The proof involves large amounts of data and calculations, far too much for here. But here's a simple picture, including the sun, volcanoes, and other things. Until about 50 years ago climate was determined by natural things, like changes in the sun. About 1960 our rapidly increasing production of greenhouse gases, mostly from burning fossil fuels, overwhelmed nature, and is causing things to warm fast.

Almost all of the world's scientists agree about this, because of the scientific data. There are only a (very) few skeptical scientists. Most all of their "scientific" arguments are answered here:

Yup, this is a natural process, and what the scientists will never tell you, is that this natural process imply a surge in volcanic activities that are going to happen in the next few years.
Global warming occur because our Earth core is entering another phase, and this phase modified the dynamic of the whole internal convective mechanisms of the planet. The effects cannot be seen by us, as they are occuring at the ocean floor, where thermal vents are getting hyper actives releasing gas and heat in our oceans. This saturate our ocean in CO2 (thus blocking the atmospheric absorbtion), and increase the average temperatures of our oceans.
Temperatures on Earth has always been regulated by our surface water temperature (over 80% is supplied by it), while gases are not even responsible for 1%, so CO2 is raising in our atmosphere but not really because of US.

I guess most scientists know the truth, but since it incures that we may live a dense and heaby volcanic activities in the coming years, they don't want to scare peoples. It a thing to get flooded, but another to know that wheterever you go, you could not escape...

climate change is a part of natural processes. but human actvities enhance thes change, make it much more faster than it supposed to be.
