1. Yes because of Carbon Di Oxide and other poisonous gases like chloro floro carbons the temperatures are gradually increasing.
Higher temperatures threaten dangerous consequences: drought, disease, floods, lost ecosystems. And from sweltering heat to rising seas, global warming's effects have already begun. But solutions are in sight. We know where most heat-trapping gases come from: power plants and vehicles. And we know how to curb their emissions: modern technologies and stronger laws. By shifting the perception of global warming from abstract threat to pressing reality, and promoting online activism. By pressing businesses to use less energy and build more efficient products. And by fighting for laws that will speed these advances.

It is thought that the Earth has gone through warming and cooling cycles in the past before humans even existed, however, the current rate of warming seems to be more rapid than models suggest if the warming were soley to the same mechanisms which caused it in the past. The current rate of warming also seems to have a direct correlation with the emissions of fossil fuel related gases such as carbon dioxide.
So in response to your question, I do think the Earth is warming up more than usual due to human activity, but I think this is overlapping a natural warming cycle.
This "extra help" from humans is worrysome not only in the extremes in weather it may contribute to, but Earth contains large amounts of frozen methane just beneath the sea floor in many areas. Should this methane melt and the methane gas escape into the atmosphere we will see a very large rapid warming spell which could make much of the Earth to hot to be inhabited by most life forms.

Yes The earth is warming up It is called global warming.
The human activity is create problems and the heat on earth is increase and green house effect is produced.

earth is warming up as a result of human activity and also due to natural cycles.

It doesn't matter what people think. Facts of nature are not determined by popular vote. Climate scientists (who study the facts, not popular opinion) are overwhelmingly of the view that human activity is warming the Earth.

Maybe, maybe not. The earth went thru it's own warm periods and cool periods (i.e. the Ice Age) before humans were ever around screwing things up. But I don't completely rule out the idea that we are ruining everything. I just don't know...

yes ..earth realy warming nupdue to humans activities like industrialisation. and ozone gt hole.........so after 10 years the sea level is increased up to 50-100 cm...then all major towns is in wolrld gone under water

Humans are contributing, however, when you consider the contributions of humans vs mother nature (volcanos alone produce more greenhouse gasses then all the cars and power plants on earth combined) we are hardly making a dent.
It is like saying that if I have a 1 gallon container and I put one drop of water in it, I am the sole reason it is overflowing. Yes it does contribute, but small in comparison.

human activity is a very broad term...... meaning everything that humans do......
with that said,,,,,, yes,,,,,humans have put a big hole in the ozone, with "activities" the are responsible for just that.
and it has caused warming .... without a doubt.....its been proven.

It is a popular opinion, and certainly possible, but I think it is more of a natural phenomenon than artificial. The earth's temperature has been changing since it came into existence; remember the Ice Ages?
