1. What is climate change and what is its origin?
Climate change is directly related to global warming due to human activities. It manifests with the increase in intensity and frequency of meteorological phenomena such as heat waves, droughts, rains, forest fires, weakening of the coral bar, possible modification of hurricane and tornado patterns. The melting of the glaciers, the loss of ice at both poles and the rise in sea level represent potential dangers for the populations of the islands and coasts. If the temperature on the planet continues to increase, there will be a greater shortage of drinking water and food.
Most of the greenhouse gases (GHG) come from the burning of fossil fuels, caused mainly by the massive use of transport and the expansion of industry, while the rest corresponds to the deforestation of woods and the increase in agriculture, livestock and some other factors. However, there is another danger, not as well-known as the named ones. It is the CO2 contained in the permafrost, which could escape into the atmosphere and cause greater damage than the conventional emission of greenhouse gases, as explained in the response to FAQ-6.
