No. The planet is heating up faster than predicted, however. The best theory to explain this is a compounding effect between increased CO2 levels (100 years in the making) plus a dearth of sun spots. Other planets are heating up as well, so it's a natural cycle along with artificial exacerbation.
Soon, the summers will be hotter and the winters colder. Let's see what the conspiracy theorists come up with then. I, for one, have faith in the majority of scientists.
Oh, and I'd read NASA's (and NOAA’s) predictions for the next solar maximum if I were you.
From a purely scientific point of view, if there were no atmosphere, then the natural temperature of the earth would vary dramatically, but hover around an average of about -18 degrees C.
It is a fact that the atmospehre traps heat, and thus warms the average temperature of the earth to life sustaining levels. There should not be any dispute on this point.
I think the dispute comes from additional warming caused by human activity. Some people say that human activity has nothing to do with increasing temperatures. However, the temperature record shows that the average temperature of the earth has increased since the mid 1800's when reliable records were first kept. This temperature record is not in dispute by any honest scientist.
What has not been conclusively shown is how this increase in temperatures will affect our climate in the future. Most honest scientists will say they don't know for sure. Most climate scientists argue that because we don't know, we should not gamble with the future of the planet on something that., if we get it wrong, would totally wipe us out.
People arguing the other side say that we don't know if increasing temperatures will cause problems, and we shouldn't destroy our economy with draconian measures that massivley increase the cost of energy and lower the standard of living everywhere.
In summary, Global warming is a scientific fact. The consequences of that temperature change is where the debate lies.
That's pretty frivolous wording in your question. No, it is definitely not a hoax. A hoax is a falsehood that is proliferated to deceive. Global warming is not a falsehood, but it is a term used to refer to the idea of an average increase in temperatures over a prolonged period.
Global warming is in fact real, for what it describes. The controversy is a direct consequence of climatologists' uncertainty about how fast and how much sea levels will rise over the next 100 years. One variable that has added to the uncertainty in the estimates is the activity of the ice shelves that can accelerate the rate at which glaciers melt. But, that's just being redundant. We cannot forecast the consequences of global warming because we cannot forecast the cleavage of ice shelves. There is a potential for catastrophic effects in the event of the worst case scenario, and some scientists are adamant that the ice shelves are disintegrating at a rapid clip, and that we ought to be very worried.
Naturally, other scientists are more cautious about making projections, and still, other scientists are just skeptical.
There are many interpretations, but it is not in dispute that global warming is real.
In addition, as noted by countrystarr, there is the assertion that humans have played a considerable role in all of this; and this makes for contentious disputes.
somebody is standing outside in winter without jacquet this year.....
the poor polar bear might need to shave off the heavy fur..... or sweat till dehydrate and lost weight or live in the freezer?
I have examined the scientific data and as scientist there is overwhelming data that global warming is here The rise in carbon dioxide emission began during the Industrial Revolution. We can get this evidence even today from ice-core samples within glaciers. Ice-cores traps valuable data on CO2 levels for over thousand or years. Here we see CO2 levels year by year for many thousands of years.
It is a fact that carbon dioxide as a green-house gas will increase global temperatures
Even if you don't understand this, you may have noted that large ice-sheets at the poles, that were there for thousands of years, are breaking away. Rising temperatures are allowing warmer parasite to infect trees in Alaska. There is less ice in the poles now. Glacier in Montana is on the way out. Ice levels in the Himalaya have also fallen. Polar bear habitat is affected. And I could go on with more evidence.
Of course our global temperature is the product of both natural and human actions. However, there is overwhelming evidence that human activity is the biggest contributor in the increase of CO2 level today.
As a political observer, the reason for your doubt is probably caused by powerful political groups and industries who make their fortune by burning fossil fuel. Many industries are uncomfortable to adapt to new technologies that will prevent or lower CO2 emissions. This confusion you and others have about global warming is intentionally created by right wing factions of our society.
When the brightest scientists sounded the alarm several years ago they were discredited by powerful groups. Politicians gave access to powerful lobbyist from the oil companies to alter the reports of these scientists.
Hope this clears the air.
Congratulations! You have just established a new Guiness Book of World Records record: best inane right-wing idiocy parroting by a non-Fox-News spokesperson.

I'm confused. I've read and heard arguments that global warming is really just part of a natural temperature change process for the earth. I've also read that it's completely man-made? Is it one or both of these? Please explain.
