The Effect Of Temperature On Dissolved Oxygen - 888 Words

The relation of earth and space science to the effect of temperature on dissolved oxygen Over the past few years, scientists are becoming convinced that climate change caused by mankind has the potential to change Earth forever. If greenhouse gases weren’t there, global temperatures would be around 20-30 degrees Celsius colder than it is now. This may be too cold for life on Earth to survive. The main force behind Earth’s climate is energy from the Sun. Energy travels from the Sun in short waves infrared radiation. Some of the infrared radiation that travels from the Sun does not get past the Earth’s atmosphere, but, a lot of it does and it is then absorbed by the land and the sea, and heats them up. The Earth re-radiates the energy back†¦show more content†¦There are always natural variations in climate, however the variations caused by humans are much greater. Our planet now, is extremely different to how it was 300 years ago. The population is now a lot larger. There has been the industrial revolution and there is more technology around today. We’ve used a lot of fossil fuels and we are now almost completely reliant on them to do most things in our day-to-day lives. When fossil fuels are burned, they produce a gas called carbon dioxide, which is also known as CO2. The human race is now producing quite huge quantities of carbon dioxide, over 7 gigatonnes a year. Carbon dioxide is a greenhouse gas that is found naturally in the Earth’s atmosphere. All the extra carbon dioxide, produced by burning fossil fuels, is making the greenhouse gases around the Earth too effective. In other words less energy escapes back into space. Instead, the trapped energy in our atmosphere heats up the Earth’s climate, causing climate change. There are also other things humans are doing that are increasing the amount of carbon dioxide in the Earth’s atmosphere. Plants and treed absorb carbon dioxide as they use it to make food through photosynthesis. This is another cause of an increase in carbon dioxide because of the amount of deforestation that is taking place. So, instead of carbon dioxide being locked away in plants and trees, it is up in the atmosphere. An example of this is
