Humanity can take action to slow global warming. As researchers have showing global warming results primarily from human activities that release heat-trapping gases and particles into the air. The most important causes include the burning of fossil fuels such as coal, gas, and oil, and deforestation. To reduce the emission of heat-trapping gases like carbon dioxide, methane, and nitrous oxides, we can curb our consumption of fossil fuels, use technologies that reduce the amount of emissions wherever possible, and protect the world’s forests and keep the world crop production stable.
We can also do things to mitigate the impacts of global warming and adapt to those most likely to occur, through careful long-term planning and other strategies that reduce our vulnerability to global warming. The IPCC Special Report on Emission Scenarios determines the range of future possible greenhouse gas concentrations (and other forces) based on considerations such as population growth, economic growth, energy efficiency and a host of other factors. This leads a wide range of possible forcing scenarios, and consequently a wide range of possible future climates. Precipitation is also expected to increase over the 21st century, particularly at northern mid-high latitudes, though the trends may be more variable in the tropics. Snow extent and sea-ice are also projected to decrease further in the northern hemisphere, and glaciers and ice-caps are expected to continue to retreat.
