One of the biggest problems facing the world is that our production of carbon dioxide and other greenhouse gases is having a heating on the atmosphere, and this could be very dangerous for human life.
Global warming means the increase in the average temperature of the earth’s near-surface air and atmosphere. It has been a very important issue all over the world. Many problems could result from global warning. One of the biggest problems is rising of sea level. This could result in the flooding of low lying coastal areas and cities such as Egypt, the Netherlands and Bangladesh. Some countries might even disappear completely.
Global surface temperature has increased 0.18 °C during the last century. Temperature increase since the mid 20th century was caused for increasing concentrations of greenhouse gases. These gases are mainly created by various human activities such as fossil fuel burning, deforestation etc. One natural cause is release of methane gas from wet lands.
Another major man-made cause of global warming is over population. More people mean more food, and more transports. It also means more CO2, methane etc. because there will be more burning of fossil fuels and more agriculture.
The effects of global warming include Arctic shrinkage, Arctic methane release, releases of global carbon, methane release, sea level rise and so on. It is causing more rainfall and floods in many areas, droughts, extreme climate incidents, and changes in climate patterns.
Some regions and sectors are in great risks for this. Low-lying and less-developed countries and areas are at the greatest risk of global warming. Adaptation potential for biological and geophysical systems is estimated to be lower than of human health.
In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future. Scientists, governments and individuals must work together to overcome this threat.
