A big increase in the earth’s temperature during the last 30 years has been one of the most important topics around the world.
Global warming is a natural event, it is supposed earth’s temperature most show important increases for tens of thousands of years, but since 1850 (industrial revolution) there has been a mean rise in global temperature of approximately 1°C.
The use of fossil fuels leading to a buildup of greenhouse gases in the atmosphere. Those gases, which the most important is carbon dioxide, accumulate then reduce the escape of the earth’s infrared radiation into space, so then earth’s temperature increases faster than past decades.
Also the use of chlorofluorocarbons, has caused the destruction of the ozone layer, that serves to shield the earth from the sun’s ultraviolet rays.
The potential consequences are so great, that’s why already in 19th century appears an environmental movement, of which the author Henry David Thoreau was leader.
Since then some people around the world, have thought about a way to minimize risks.
The biggest effort to reduce gas emissions happened in 1997. Delegates from the most industrialized countries in the world, especially those that are part of G7, resolved to limit emissions of gases, it was known as the Kyoto protocol.
USA, which is the most important emitter of greenhouse gases, hasn’t reduced it like it was resolved and even it is the biggest emitter in the world.
If it continues like this, we’d have to look for another place to live.
