There are many theories about the global warming, but only one is unanimous: Global temperatures have risen about 1 C since the Industrial Revolution in the mid 1800s. Compared to climate changes in Earth s history this is frighteningly fast. And scientists found out that climate changes have always been linked with CO2 emissions, which are a world problem in the 21st century. So many oil companies point to the ice age, saying natural climate changes can happen. In fact, the upcoming global heating is caused by the humans. In the last years, scientists found out that the level of flooding, rising sea and rain- and snowfall is increasing and also calculated that a temperature increase between 1 and 3 C would cause a rise of the sea level between 15 and 120 cm, which is possible within the next 100 years. Any area 2m above sea will be at risk in only 30 years time. This would mean that lots of important cities like New York, Boston, Miami and Washington DC could soon be submerged in water.
