We are going to talk about climate change and the effect it is having and will have on the Earth. Climate change refers to long term shifts in temperature ce and weather patterns.
These shifts may be natural, but since the 1800s, human activities (like industries, factories, cars) have been the main driver or factor of climate change, primarily due to burning fossil fuels like coal, oil and gas.
The Earth has got an atmosphere. It is made of gases. The greenhouse effect is what allows life on earth. Without the greenhouse effect the average temperature of the earth would be -18 C rather than 15 C. However it becomes problematic when we increase the amount of natural gases in the atmosphere and they are no longer in balance.
Since the 1800s the human activity has contributed to increase gases to be released into the atmosphere. The atmosphere is the blanket that keeps us warm and now it is too thick. There are activities such as big industries and cutting down trees in forests that cause that increasing heat.
5 VIDEO Over the year the planet evolves everybody evolves in a specific set of conditions. Even what seems like a slight of change can cause these conditions very drastically. We evolve at a particular temperature. This can throw a whole lot of things out of balance.
In some countries they are more vulnerable to the effects of climate change than others. For example, in South of Asia where there are a lot of islands close to sea land. They don’t reach that high. They are four metres above sea land and with the heat of the earth and the melting of the ice caps of the Arctic and the Antarctic.
If your house in the island is only 3 metres above the sea and the sea rises 3 metres then you are going to lose your house. It’s expected that there’s going to be a lot of refugees that have to move because of some kind of catastrophes. We have refugees from floods or diseases, anything that displaces someone from home.
This is the diagram of the sea level rise. This is another impact of it even if your house is a bit higher up. If you live in a place where you’ re twenty or thirty metres above sea land, in the rivers sea water rises because sea goes inland pushing up rivers. It’s bad for us because a lot of fish that live in rivers or lakes they have to evolve to survive in fresh water, without salt.
Every increase in global warming matters in a 2018 UN report, thousands o scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5ºC would help us avoid the worst climate impacts and maintain a livable climate. Yet based on current national climate plans, global warming is projected to reach 2.7ºC by the end of the century.
Based on this future the temperature will be 2.7 higher and will cause problems to the earth. One of the most unfair things about climate change is this disproportional effect that has on several countries depending on where you live. The 100 least-emitting countries generate 3 percent of total emissions. The 10 countries with the largest emissions contribute 68 percent. That means releasing gases into the atmosphere.
The problem with this is that countries like US and China are less affected than other countries. It’s not just government is also industries as well. Industries like coal or oil have been fighting. They don’t want to change their waste because they make a lot of money of oil. They essentially have shorter vision where they don’t want to change their practices because they make money of oil now. And a long time changes wouldn’t really affect them now because they still make money in the next thirty or forty years. Essentially in the carbon rate, we solve the way climate change will endeavour around the world especially in the west is we are not doing enough to combat climate change.
What is the environmental impact of your area?
It is a questionnaire to know the annual footprint of your house. There are two videos of the questions of the questionnaire: Of the food you buy how much is wasted and thrown away? Or what kind of house do you live in?
