Climate change

• The natural/enhanced greenhouse effect is a process that increases the Earth's temperature due to the presence of greenhouse gases such as H2O, CO2, CH4, and N2O.
• H2O, also known as water, is a greenhouse gas that is released into the atmosphere through cooling towers.
• CO2, also known as carbon dioxide, is a greenhouse gas that is released into the atmosphere through burning fossil fuels.
• CH4, also known as methane, is a greenhouse gas that is released into the atmosphere through agriculture.
• N2O, also known as nitrous oxide, is a greenhouse gas that is released into the atmosphere through the chemical industry.
• GWP, or Global warming potential, is a measure of how strong a greenhouse gas warms the atmosphere.
• The albedo effect is a process that decreases the Earth's temperature due to the presence of snow and ice.
• The greenhouse effect decreases the albedo effect.
• An enhanced greenhouse effect occurs when ice and snow melt, causing the temperature to rise and more ice to melt.
• IPCC, or the intergovernmental pannel on climate change, is a group of scientists from around the world who assess and provide information on climate change.
• IPCC future scenarios include temperature changes, precipitation changes, and impacts on specific regions such as the North Pole, North Africa, China, India, the oceans, and Brazil (Amazon).
• COP, or the conference of the parties, is an annual gathering where countries that are part of the United Nations Framework Convention on Climate Change (UNFCCC) come together to discuss and negotiate climate change issues.
• Global warming now is 1,1°C and must stay under 2° (preferably 1,5°).
• Sea ice (Arctic) doesn’t rise the sea water as much as land ice (Antarctic) because the sea ice is already in the water so it takes in its own volume.
• Sea level rise and the albedo effect form a vicious circle.
• The treeline is the edge of a habitat where trees can grow.
• When the climate becomes warmer, the treeline will move up to the North, decreasing the tundra areas and affecting the inhabitants' living space.
• Certain species may not find food due to climate changes, leading to migrations, evolutions, and extinctions.
• Extreme weather conditions can be caused by climate change and solutions include transportation and agriculture.
• Governments should focus on limiting one of the world’s biggest sources of pollution: gasoline-powered cars.
• Electric vehicles or rethinking our transit systems could help massively.
• Agriculture should focus on eating less meat, especially beef and lamb, as they produce methane and need a lot of feed, for which trees are cut (deforestation in the Amazon and Indonesia to grow soy and palm oil).
