The natural process of the earth heating up over time in between glaciations. In recent times this process has been sped up dramatically because of the burning of fossil fuels, as well as occurances in nature as the result of global warming. The increase in heat leads to ocean levels rising, lifeforms dying, and people becoming pissed off. Over time it can cause massive climate shifts.

continuing increase in the average temperature of the air and the oceans

A heating of the earth caused by people who are simply too hot.

what my friend wants me to write a report on over summer vacation. It has some thing to do with the Earth being so polluted that the Earth is going to kill its own people. Or something like that...

In simple terms, the rising mean surface temperature of Earth. There is a scientific consensus that {yes} global warming is occurring. In fact the mean surface temp. has risen a staggering 0.5 C in the past 180 years.

This is what we know as fact, however there are numerous different ideologies associated with what is making global warming. {Side note: the earth has been warming and cooling since its creation, this global warming/cooling is no new climate terminology to the planet}

First Theory: GHG(Green House Gasses) are creating trapped heat through infra-red radiation.{Further explanation is needed to fully understand GHG Warming please go look it up} Also that from these GHG's, CO2(Carbon Dioxide) is the only one that makes a considerable difference{even over water vapor which makes up 1-4% of the atmosphere while CO2 is in the 300PPM quantity}.

Second Theory: Solar sun spots are creating an increase in solar activity and solar radiation{UV}. The sun has been putting out more sun spots thus creating more solar radiation making the earth warming.

These are the two most popular theories today, although 85% of people are blindly accepting the first one. Please don't take other peoples view on global warming, visit websites(Both for human and non-human causes) and decide for yourself, learn the science behind it before committing to a side.

Some interesting facts, due to everyone looking up to Al Gore{Who recently is under review to get his Oscar taken awa...

A term which has been the subject of much heated debate. It is either used to describe consequential escalating global temperatures or the tree huggers' fear weapon to fuel the "Go Green" movement.
