Global Warming

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.

The UN Global Warming Report Facts and Predictions

The latest report from the Intergovernmental Panel on Climate Change delivered a huge blow to global warming skeptics. Leading climate scientists are now 90 percent sure that human activity is heating up the planet. They present various scenarios that show where global warming could take us by the end of the century. The choice is ours.

What Is The Greenhouse Effect?

Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is this gaseous outer ring and its misleadingly called greenhouse effect that makes life on Earth possible – and that could destroy life as we know it.

About Global WarmingMany observations indicate that global

warming has taken place during the 20th century. Global warming has resulted in a increase of the average surface temperature, a decrease in snow cover and ice extent and a rise of the sea level. Moreover, global warming affects precipitation, cloud cover and extreme temperatures.

Facts of Global Warming

Global warming has and will always vary for natural reasons. However, human activities are increasing significantly the concentrations of some gases in the atmosphere, such as greenhouse gases (mainly CO2), which tend to warm the earth surface, and anthropogenic aerosols, which mostly tend to cool it.

Consequences of global warming

The predicted effects of global warming on the environment and for human life are numerous and varied. Scenarios studied by the Intergovernmental Panel on Climate Change (IPCC) predict that global warming will continue and get worse much faster than was expected even in their last report.

What are the Causes?

Natural reasons will always affect global warming. However, human activities are increasing significantly the concentrations of greenhouse gases, mainly CO2) in the atmosphere, resulting in global warming.

The Consequences

It is notable that many of the effects of global warming are non-linear in nature, with potential for dramatic positive feedback effects. This means that the climate may enter a critical state where small changes can trigger runaway or catastrophic climate change.

My Opinion

Well my opinion is that people should take Global Warming seriously because this could kill all human raise and animals.
