Climate Change

Part 1: THE CAUSES

The Greenhouse Phenomenon is a natural process that allows the Earth to mantain the necessary conditions for life: the atmosphere retains part of the heat of the Sun. Without it, the temperature on Earth would be -18ºC.

The problem is when we increase the emission of gas like carbon dixide, methane or oxid of nitrogen, and the atmosphere retains more heat than necessary. That emission of gas comes from Industrial Revolution since now. But this isn't only the problem. The  destruction of life in forests and acuatic ecosystems by the human makes also the climate change, because they are in charge of absorb part of the dioxide of carbon to live.

Part 2:THE EFFECTS

The global temperature has aumented 1.1ºC and it will increase in the following years. But, how does climate change affect us? This global increase brings consequences that endanger the survival on the Earth: flora, fauna and humans. First of all, it makes all the ecosystems change, because animals have to change their habitat or they die, and higher temperatures make some plants to die, so some ecosystems become deserts.

In other ones, like in the North and South poles, ice melts on summer because of high temperatures, so it destructs places to live for polar bears or foxes, and there is also more water on the seas and oceans and it could flood beaches or cities soon. Sea level rises 5 mm in a year. Animals and plants have to adapt to this changes, so lots of them are extinguishing.

The climate change makes also modify the wheather conditions, which are more extreme. For exemple, there are actually many natural disasters like tornados, hurricanes and strong rains, like that one that occurred last september in the southwest of Spain, while in other places there is drought or big fires, like in Australia, which destruct crops and kill plants and have destructed more than a billion animals.  

Part 3: HOW COULD WE STOP IT?

It's important to make clear that climate change cannot be avoided, but we can reduce its effects. We can combat it by applying some mesures.

79% of carbon dixide comes from burning fuel to make energy for transports and factories, and 91% of the energy resources aren't renewable. So we must use renewable ones in stead of the others because this ones don't pollute, or we can reforest some zones because plants help us absorbing carbon dioxide. But we also have to collaborate, for example, not wasting much energy at home.
