tThe main causes of this phenomenon are the gases, especially CO2, which daily human activity emitted by electricity consumption (as most we get electricity by burningcoal, oil and gas), transport motor and heating systems that rely on fossil fuels like coal, oil and gas. We also contribute to the emission of CO2 through irresponsibleconsumption, as in the sale of a product's energy expenditure of production and transportation (if the product is produced in addition to spending long distances willbe greater, and if it consists basically of plastics and other petroleum products).
We all contribute in our daily climate change. We use a system of electricity thatcomes from non-renewable energy. We drove in vehicles (buses, cars, motorcycles) using fuels from non-renewable energy and emit greenhouse gases. Generate large amounts ofwaste that remain in our environment for years and damage the environment. Tear down trees to use paper and contribute to deforestation. More and more arable land isneeded because the world is densely populated and needs more food to feed so many people ...

          The increase in greenhouse gases affect climate, but do not knowexactly to what extent. But is that even if we understood better climate change undoubtedly we would find surprises. The weather does not follow a linear pattern and notsee all the consequences of our actions until it is irreversible. Moreover, the climate does not respond immediately to emissions of gases, but many greenhouse gasestypically remain in the atmosphere for decades, influencing the climate for long. This delay in the effects, increases the risk that when it is too obvious, it's too late.
