CLimate Change
Climate change is where the pattern of weather conditions and temperatures as well as periods of freezing and unfreezing change over time. The evidence of climate change links back to the amount of CO2 in the atmosphere, and as this amount rises, so does the temperature of the planet. In the past 150 years, temperature increase coincides with a consistent rise in the amount of CO2. There are three types of greenhouse gasses, carbon dioxide, methane, and water, that all with solar radiation control the temperature of the Earth through what is called the greenhouse effect. Dr. Shrag helps to explain the correlation between greenhouse gasses and the rise of the Earth's temperature in recent years, also relating to climate change. He looks at evidence of climate change as well, showing trends. Shrag says that because there is so much CO2 in the atmosphere currently, above the natural level and taking Earth out of its natural cycle of heating and cooling, it will take melting the glaciers and many years for us to fall back into an ice age (future ideas). Milutin Milankovitch correlated changes with the Earth's orbit and the interglacial and glacial periods. He was a Serbian astrophysicist (1879-1958). The effects of climate change include: heating and cooling of the Earth, and lots of variability. The rate of change may be very high or unusual, and can have effects on life.
The US gives off a lot more CO2 per person than Mozambique. I think the US produces a lot more because there is a difference in the level of development and the type of technology used. There is also a major attitude difference- the US is more focused on always advancing and keeping their economy stable at the expense of the environment, while Africa is more focused on nature and the natural species that reside in the region.
It is not fair that some countries give off more CO2 than others, but do not always have to deal with the consequences. Some countries with the more eco-friendly mindset, living more traditional lives that are more focused are suffering more than those who are doing the harm and harming the environment.
Most commonly, seasons are shortened or extended so there varying degrees of water throughout the year. When there is a lack of water, plants die, and because the plants die, the animals die because they cannot eat the plants or drink the water. Then, humans starve and are dehydrated because they cannot drink the water or eat the animals because the animals have died out.
The graph says that only a quarter of emissions are hard to eliminate. A lot of the graph, 39% has to do with electricity and heat, which can be brought down with less demand for unnecessary and wasted products, as well as amenities. Unplug devices not being used to save on energy costs. Wear warmer clothing inside instead of turning on the heater when it starts to get slightly colder out. Cars give off a lot of CO2: people can stop driving cars as much, and use public transportation instead. This would somewhat go under short-distance travel, which is around 16% of the graph.
