Climate Change

Issue

Climate Change is a shift in weather conditions by changes in temperature , rain , wind etc. Climate Change will have a big impact on people , ecosystems and cities. Climate started to change the most in the early 19th century when greenhouse gas emissions were first suspected. Climate Change is often said as one of the most serious environmental threats to us.

Causes

Climate Change is caused by human activities. The main cause is carbon dioxide but carbon dioxide is also enhanced by other greenhouse gases too. This can influence both incoming and outgoing energy and can have both cooling and warming effects in the climate. With change is the climate what can happen is the earth will start becoming either warmer or cooler and while some places may welcome and benefit the change in climate others may not. How some people could benefit from climate changes some crops may be able to benefit from the change in weather patterns and might be able to grow in places where it wasn't able to grow before but changes in weather patterns could also have a negative effect like it could melt glaciers and increase sea level. The reason carbon dioxide is the main cause for climate change is for example sunlight passes through to warm the earth and most escapes to outer space letting the earth to cool but some gets trapped by carbon dioxide and other greenhouse gases that are in the air not letting it go through heating up the earth. Scientist say that since the 1990's 8 billions tons of carbon dixode have been released into the atmosphere and are saying that by 2020 that number will 11 billion.

How Climate change contributes to global warming

How Climate Change contributes to global warming is that climate change increases temperature which makes weather warmer and warm weather will melt glaciers and other ice in the arctic and that will put more water in the ocean which will make sea levels rise. Warmer weather is also effecting rainforest numerous rainforest over the world are getting dryer.

Long term effects

All around the world the effects of climate change is increasing a lot and no one can ignore it. What has happened that glaciers have started to shrink because the ice has been melting because of the hot weather when it is supposed to be colder. Sea levels are rising around the world because ice is melting. There could be changes in the earth's orbit. A continental drift could happen and the continent could become closer or grow farther apart and the ocean bodies could shrink and some could become bigger. Food production systems depend on climate. Carbon dioxide is also the main cause. In North America it is snowing less. Climate change is causing heat waves and the winters are starting to get warmer.

What can be done

We can reduce energy and that can reduce climate change. We can use energy more efficiently. We can use alternative sources of energy to fossil fuels. We can improve public transit this will play a great roll in carbon dioxide reduction they are run very poorly. We can develop renewable energies, including biomass fuels, wind turbines, solar energy and geothermal energy. Wind turbines reduce climate change. They are an excellent solution. We can use solar heating panels. geothermal energy is used in volcanic countries like Iceland.

What Canada is doing and the world is doing

Canada is supporting efforts to protect the environment by developing policies and programs. In Sweden they are producing environment friendly cars. The EU leaders are committed into transferring Europe into a highly energy-efficient low carbon dioxide economy and has set targets onto for reducing greenhouse gas emissions and is working towards meeting them.
