Climate Change
Management
Planting Trees: if we where to start planting more trees or to manage the ones that we have left it would decrease the amount of CO2 in the atmosphere and increase the amount of oxygen allowing us to have cleaner air
Alternative Energy Supply: we use a lot of fossil fuels for our energy or other energy sources that release Co2 in the atmosphere, we should decrease the amount we use and use more that are Eco friendly like solar panels and wind turbines
Carbon Capture:Carbon capture and storage (CCS) (or carbon capture and sequestration or carbon control and sequestration is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere
International Agreements: these are when countries will come to an agreement to when they are to stop using factory's that emit CO2 and cars
Impacts
On farming: with longer summers, we will be getting less water for plants and it would lead to more of them dying which could lead to droughts and people starving due to the lack of food in a certain region
Rising Sea Levels: as the sea levels rise due to the polar ice caps melting and rising the sea, soon they will all be gone and large amounts of populated land will be under water and have to be relocated
water supply: the effect of warming is to increase the amount of water that the atmosphere can hold, which in turn can lead to more and heavier rainfall when the air cools. Although more rainfall can add to fresh water resources, heavier rainfall leads to more rapid movement of water from the atmosphere back to the oceans, reducing our ability to store and use it.
Evidence
Recent Evidence
Glaciers throughout the world are melting and shrinking and retreating. it is estimated that some may disappear completely by 2035. arctic sea ice has thinned by 65% since 1975 and in 2014 its extent was at an all-time low.
Sea Level may rise by 1m by 2100 flooding agricultural land in Bangladesh, Vietnam, China and India.
Seasons: Studies have suggested that the timing of natural seasonal activities such as tree flowering and bird migration is advancing.
Historical evidence: historical evidence can be used as we no previously that the climate was not as extreme 100 years ago since we used to have no factorys
Causes
Natural Human
CO2 Emissions (There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.)
Nitrous Oxides (is naturally present in the atmosphere as part of the Earth's nitrogen cycle, and has a variety of natural sources. However, human activities such as agriculture, fossil fuel combustion, wastewater management, and industrial processes are increasing the amount of N2O in the atmosphere.)
Methane (a colourless, odourless flammable gas which is the main constituent of natural gas. It is the simplest member of the alkane series of hydrocarbons)
Volcanic Activity :volcano still are active to this day and they when they erupt they release large amounts of Co2 and ash into the atmosphere heating it
Solar Activity:Over the last 35 years the sun has shown a cooling trend. However global temperatures continue to increase. If the sun's energy is decreasing while the Earth is warming, then the sun can't be the main control of the temperature.
Change In Earth's Orbit:
The Earth’s orbit around the Sun is an ellipse, not a circle but the ellipse changes shape.
Sometimes it is almost circular and the Earth stays approximately the same distance from the Sun as it progresses around its orbit.
At other times the ellipse is more pronounced so that the Earth moves closer and further away from the sun as it orbits.
