This is the question of global warming.
The rise in global surface air temperature causes frequent droughts in dry areas and accelerated ocean warming and hence the rapid increase in sea levels and melting of the polar ice caps....
We aren’t necessarily warming either.
Once upon a time everyone talked about the Ozone Layer; now you rarely hear about it. That doesn’t mean it’s status does not weigh heavily on global warming. Quite the opposite, its continued destruction by geo-engineering has only accelerated the depletion of this vital buffer against damaging radiation from the sun. You can imagine how much cooler the high concentrations of O3 keeps the surface of the planet by absorbing so much ultraviolet radiation.
Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well.
We, as humans, are responsible for global warming.
(sigh...) It ends with Hurricane Katrina and Boston almost losing the pennant. It is Hollywood at its finest, and the Deacons of La La Land give it an Oscar. Even the Nobel Committee is impressed, gives it two thumbs-up and a Nobel Prize to Gore and the other members of the IPCC for the many lives that will be saved in the future because of this brilliant early warning. And, there's still time for we miserable humans to "save" the planet by buying "carbon offsets" accomplished best by investing in Al Gore's British company which buys stock in other companies that will benefit from a world-wide global warming hysteria (keeping a healthy cut) and making, perhaps, Al Gore the richest former Vice President in history. That will buy a lot of SUV's, jets, and large mansions with mega-electric bills. Everyone wins except the taxpayer and businessman, who are soon to pay a very heavy price.
Global warming is gasses that are trapped in the atmosphere.
It is often talked about that the primary reason why the global warming situation is increasing is due to the increase of the amount of greenhouse gases present in the Earth’s atmosphere, primarily the amount of carbon dioxide emissions.
These are just a few contributing factors of global warming.
Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface.1 The molecules are kind of like glass in a greenhouse which is why this process of warming is called the greenhouse effect....
The world is changing because of Global warming.
The increased carbon dioxide amount in the atmosphere that causes global warming is a cause of concern for many people because of its potential dangerous effects to the Earth and the environment....
People living on earth are responsible for global warming.
What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas -- water vapor -- into the atmosphere every day, and removes about the same amount every day. While this does not 'prove' that global warming is not manmade, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds."
