About globalwarming
The Sun sends energy in the form of radiation to the Earth. The Earth reflects approximately 30% of the incident solar flux. The remaining 70% is absorbed, allowing the land, atmosphere and oceans to warm up to a livable temperature.
Since the Industrial Revolution in the 18th Century, the burning of fossil fuels, such as coal and oil, and deforestation has caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. This causes less heat to reflect and more to be absorbed.
According to the IPCC (Intergovernmental Panel on Climate Change) there will be a global temperature increase of 1.4 - 5.8°C from 1990-2100. The increase in temperature will cause a rise in sea levels, extreme storms and diseases such as Malaria, Dengue Fever, Encephalitis and Hantavirus. It is predicted that we will lose nearly a quarter of the Earth’s animal and plant species by 2050.
It is time to make a change. This group is a place for us all to discuss the latest news, possible ways for change, and anything related to climate change.
