The factors that affect global warming environmental sciences essay

What exactly causes global warming?

Human causes of global warming

Assuming high growth in greenhouse gas emissions SRES A2 , some models projected that Arctic sea ice in the summer could largely disappear by the end of the 21st century. Thankfully through time we have developed new technology to reduce the effect of global warming. However, fossil fuel combustion, industrial processes, agriculture, and forestry-related activities emit other substances that also act as climate forcers. By contrast, the SRES A2 scenario showed only a small decrease in the risk of hunger from levels. This rate could speed up if we keep burning fossil fuels at our current pace, some experts say, causing sea levels to rise several meters over the next 50 to years. There are extremists who do everything possible to stop contributing to the warming, but the average person does little to alleviate the issue and in many cases refuses to acknowledge that there is a problem at all. In definition, global warming is the rise in temperature of the earth because of an increase in greenhouse gasses trapped within the ozone layer. In the same year, British Prime Minister Margaret Thatcher, whose qualifications were in chemistry, warned of the greenhouse gases being pumped into the atmosphere and warned about the effects they will have in future. Thinning in orange and red, thickening in blue. Emissions of other substances that warm the climate must also be substantially reduced. Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. There exist many contrasting viewpoints which yield very distinctive stances on the subject. Not all of the effects of climate change were included in their estimates, for example, the effects of more frequent and extreme storms were excluded. Environmental Protection Agency pledged to reduce carbon pollution from our power plants by nearly a third by , relative to levels, through its Clean Power Plan. Global warming is the escalation in the average temperature of Earth's near-surface air and oceans that has been occurring since the middle of the twentieth century and its anticipated perpetuation.

This was crucial in taking study of the climate forward. Other short-lived climate forcers have climate cooling effects, most notably sulphate aerosols.

Population III. Global warming can only be stopped by reducing global emissions of carbon dioxide from human fossil fuel combustion and industrial processes to zero, but even with zero emissions, the global temperature will remain essentially constant at its new warmer level. Deforestation 3.
