Global warming is a climatic phenomenonthat increases the world surface

temperature. Its caused by anexaggerated process of greenhouseeffect, which get worse because of thepollution process.

It prevents harmful ultraviolet radiations.Ozone Layer Hole first detected in

Antartic.Since that the layer is getting

thinner in a lot of parts arround the world.About 20 kilometers thick, this giantumbrella is made up of a layer of ozonegas.Lots of chemical substances damage theOzone Layer , contributing for the globalwarming.

The principal consequence will be a greatincidence of skin cancer, unstable climate,which could harm delicate organisms,putting at risk all the food chain. Resultingtoo in a greenhouse effect

Greenhouse Effect Greenhouse Effect

Incredibly, if Earth wasnt affected by thegreenhouse effect, the life would be impossible.Probably without it, our planet would be like

Mars. Mars dont have a thick atmosphere toreflect the heat to itself, making the planet verycold.Therefore, the greenhouse effect generated bynature, is really good for the Earth andindispensable for keep life in the planet.

What is making the Greenhouse effect getworse, is the great level of pollution in the World,which is increasing year by year. These gases,like carbon dioxide, nitrous oxide and methane,are making a kind of extra protection, thatabsorbs the reflected infrared irradiationsemitted by earth and reflect it again, making theearth surface get almost twice as muchirradiations that are sent by the sun.Turning world hotter.

So, what really happen is that these gases dontallow the heat leave earth

Increase of ocean water temperature, causingstrong storms like hurricanes .

Fast melting glaciers, could accelerate thewarming process, because less energy will bereflected by the earth surface.

Melting Glaciers, will increase the level of

oceans, sinking coastal areas.

Areas of Earth covered by ice is decreasing.

Vegetation areas will die and Deserts will appear

A great change of climate will harm delicateecosystems, killing thousands of species andputting at risk all the food chain

Droughts and fires

Amazon could lose 10 to 25 percent of it forest

Was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February2005. 184 Parties of the Convention haveratified its Protocol to date.

The Kyoto Protocol is a legally bindingagreement under which industrialized countrieswill reduce their collective emissions of greenhouse gases by 5.2% compared to theyear 1990 (but note that, compared to theemissions levels that would be expected by2010 without the Protocol, this target representsa 29% cut).

To be in force,55 ratifications have to be sign.Just in 2004 it happen, after Russia sign thedocument. Today more than 100 countriesratified the document, but the US, the biggestemitter of greenhouse gases in the world didnthave sign it. The US said that if they had done it,they would be harming the country economy
