Yes it has. It is causing the North and South poles to melt. I'm sure that 5 years ago it wasn't as bad, but it was still doing some damage. I don't think it affected anyone 100 years ago though.
Over the past 2,000 years, global temperature trends have shown fluctuations, with periods of warming and cooling. However, in recent decades, there has been a notable increase in global temperatures, largely attributed to human activities such as burning fossil fuels and deforestation. This phenomenon is known as global warming.
Global warming is happening and the earth is not cooling. It is warming. 2010 and 2005 tied as being the two hottest years on record, and the ten hottest years since 1800 have all been in the past fifteen years.
Yes, we have known about global warming since about the middle of last century, but governments have been slow to act. Politicians rarely can see beyond the next election, and action on global warming takes some years before we see a result. Now, as global warming and its effects are beginning to be more obvious governments may act.
Since the industrial revolution from about 1800 man has been releasing enormous amounts of CO2 into the atmosphere causing the green-house effect and leading to global warming. The process has accelerated as the population of the Earth grows and more countries get industrialised.
Yes, it has caused (in the past) some more cold-reliant species to die. But, it has also cause some new species (like insects) to come up in the past as well. So some of both. *(Note: This is millions of years ago, NOT the current global warming.)
Yes, the ten hottest years on record have all occurred since 1998.
Global warming is a rapid change. The earth's temperature has risen very fast in the past 50 years, compared to the very gradual rise over the past 12,000 years, the time of the last Ice Age.
It is not. The past 10,000 years has shown warming, but the rate is slow enough for all animals to adapt.
If global cooling means the gradual cooling into an Ice Age, then that has happened in the past and it has taken thousands of years to happen. The present global warming has all happened far faster, in less than 200 years, and is threatening all life on the planet if we can't stop it. Global warming is by far the more dangerous situation.

The process of global warming, that is the recent warming over the past 200 years since we began to seriously burn fossil fuels (coal, oil and natural gas), is notcrucial to earth. In fact it is extremely dangerous.The greenhouse effect, which has kept the earth warm enough for life for millions of years is crucial to earth. But the greenhouse effect is not the same as global warming.
None.
Not quite, though they are very closely connected. Global warming is the warming of the earth. This is causing climate change, which is the many different changes in climate that are beginning to happen.

There is way too much emphasis on "Man made global warming." There is no such thing. There is global warming and global cooling that has taken place over the past ten thousand years. It is cyclical. Most of the global warming that has taken place was prior to any use of fossil fuel. Don't let people try to pull the wool over your eyes. Don't let them scare you into their mold. That's what they are trying to do. The earth will be in fine shape in 50 years.
Two words... Global Warming...
The most valid way to study global warming is through history. Scientists observe the past occurances of climate, environment, atmosphere, etc., to understand the way global warming is developing over time. To gain the most insight on global warming, it would be wise to work alongside someone who is studying it themselves. Global warming is simply a matter of tracking trends and analyzing patterns to make inferences. If you are doing this, you are studying global warming,
