Global climate change is a fact, demonstrated by historical evidence about the composition of various gases throughout Earth's history. Global temperature changes over time ("ice ages", "warming periods") Ice core sampling in the Arctic and Antarctic circles give us a record of CO2 and CH4 (methane) levels, as well as nitrogen and oxygen levels. From this information, climatologists can calculate average temperature over time. As far as the evidence shows, the composition of the Earth's atmosphere has stayed essentially the same for the last 800,000 years, as far back as ice core records can show. This composition is the textbook common 78% nitrogen gas, 21% oxygen gas, 1% other (Argon, CO2, water vapor, Neon and Helium). CO2 is of particular importance to the discussion on global warming because experiments have shown it to absorb infrared light (what we feel as radiated heat, by the sun or a fire), and therefore increase the temperature of the atmosphere. It is also known that since the Industrial Revolution, which brought about the common use of fossil fuels, global CO2 levels have nearly doubled.
A:The simple answer is yes: Temperature records show that average global temperatures have risen by 0.75 degrees Celsius since the Industrial Revolution and are now the highest for at least two thousand years, estimated to likely be the highest for at least a million years. And most of this rise has occurred since the 1970s. For the purpose of this question, we do not need to establish why this rise has occurred, but even sceptics acknowledge that carbon dioxide levels have risen rapidly since the Industrial Revolution.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Approximately 97 of climatologists believe in global warming.
Global warming in itself isn't pollution - global warming is the gradual warming of the earth. However, global warming was caused by carbon dioxide pollution in the atmosphere, but global warming in itself isn't a pollution. yes it is a pollution
Global warming is the name given to the recent (over 200 years) gradual increase in the temperature of Earth's atmosphere.
No, Hurricane Katrina caused flooding and terrible damage to humans and property, but it did not cause global warming. Global warming is caused among other things by man burning fossil fuels (coal, oil and natural gas) and putting greenhouse gases into the atmosphere.
Yes. And also with it.
1st. that's not a question, it's a statement 2nd .Global warming doesn't exist 3rd this answer is kind of bad

global warming!!!!!!
You loose non renewable resources. And no, Fossil fuels do not contribute to global warming(Biggest lie ever) Research about it, Because its a fact that Global Warming doesnt exist.
There is no such thing as "a global warming" global warming only happens to earth because human and our unruly decrease in the earths resources. HUMANS cause global warming.
Rhinos are afforded protection by law from poaching everywhere they exist. Sadly, they are not always protected well enough. Nowhere are they protected from the dangerous impacts of Global Warming.
Global warming doesnt exist you idiot hippies!
The meaning of global warming in Filipino is "pandaigdigang pag-init."
Global warming is not natural, it is caused by people. Since there aren't people on Neptune, it cannot have global warming.
No, chlorine has no effect on Global Warming.
The name says it "GLOBAL" warming.
