When we talk about global warming we are talking about the continued rise in temperature on our planet. There are different gaseous pollutants from nature that contribute to global warming; however, it is known that human activities have contributed 90% to draw the situation of environmental crisis we are currently experiencing. But what are the causes of global warming? In will we discover.
The greenhouse effect
Although it may seem new, the term ” greenhouse effect “first appeared in 1824 when Fourier began to study the planet’s temperature. When we talk about greenhouse we refer to the presence of gases in the atmosphere that contribute to absorb and emit infrared rays.
These gases are CO2, methane and water vapor and, in certain proportions, can heat the atmosphere avoiding extreme temperatures.
However, if these gases are present in the atmosphere in a disproportionate manner, as they are at present, the consequences are dire: the ozone layer is destroyed and this makes falling more infrared rays in Earth’s atmosphere and at Therefore, there is a global warming.
The greenhouse effect
Gaseous
Since the Industrial Revolution, the presence of carbon dioxide in the atmosphere has increased by 35% and this dynamic is increasing: the researchers say that the gas increased by 0.4% each year and will continue if we do not change our energy behavior.
The greenhouse gases are one of the causes of global warming and carbon dioxide and methane are gases that have always been on Earth but their presence has been increased because of man.
Most of these greenhouse gases come from burning fossil fuels in factories, cars and power supply. Other gases are also emitted into the atmosphere come from landfills (with the burning of waste), agricultural activities (by the use of fertilizers and chemicals) and deforestation (which decrease the CO2 reserve so that we natural).

Consequences of global warming
Excess greenhouse gases in the atmosphere have caused the ozone layer is destroyed, the layer protecting us from infrared rays. The consequences of this break make the temperature of our planet to be increased and, therefore, are a change in our ecosystem is reflected in:
Deforestation different plant species have been destroyed because of climate change as weather conditions that needed to be alive have changed.
Desertification: the rising temperatures on Earth have caused some regions have lost their wildlife and flora, empty.
Melting of polar ice caps: one of the most dangerous consequences arising from global warming and that is if the ice caps melt, sea level rise and cause flooding of islands and countries where people live; besides destroying fauna and flora resident caps that would end up dying and orphaned.
Consequences of global warming
What can you do?
As you have seen, the causes of global warming resulting lifestyle that people have adopted from the Industrial Revolution. These causes can be modified individually by taking some simple guidelines for sustainable living:
- Use bicycle or public transport
- Recycling waste: plastic, cardboard, glass and organic
- Become appliances energy efficiency
- Use recycled products: no plastic bags or aluminum foil to
