-World's coal, oil and natural gas industries dig up and pump out about seven billion tons of carbon a year, and society burns nearly all of it, releasing CO2.
-Every increase in concentration carries new risks, but avoiding that danger zone would reduce the likelihood of triggering major, irreversible climate changes like disappearance of the Greenland ice cap.
-One future is if emissions are frozen at present value of seven billion tons for the next 50 and reduced by half the following 50.
-As GWP grew 3% a year on average, carbon emissions rose half as fast. Ratio of emissions to dollars of gross world product fell about 1.5 percent a year.
-For emissions to be the same in 2056 as today, carbon intensity will need to fall not half as fast but fully as fast as the global economy grows.
-Two long-term rends are certain to continue and will help.
additional ways to use electricity more efficiently
-High oil prices are lowering cost of the transition to technology that can capture CO2 and pump it into the ground
-Captured CO2 can be sold to an oil company that injects it into oil fields to squeeze out more oil
-High price of oil means more valuable the capture CO2.
-Oil accounted for 43 percent of global carbon emissions in 2002, coal accounted for 37 percent
-Reduced use, improved efficiency and detrity would, the transport system could become more carbon-intensive.
-Coal-based synthetic fuels provide a way to reduce global demand for oil
-Farmers practicing no-till agriculture would contribute
-Price needed for jump start is $100-$200 per ton of carbon.
-$100 per ton of carbon is $12 per barrel of oil and $60 per ton of coal
-Other policies can harness capacity of energy producers to promote efficiency.
-To freeze emissions at the current level, if one category of emissions goes up, another must come down.
-2056 emissions in half will not be harder than keeping constant levels
-Vigorous effort can prepare revolutionary technologies that will give the second half of the century a running start.
-Options could include scrubbing CO2 directly from air, carbon storage minerals, nuclear fusion, nuclear thermal hydrogen and artificial photosynthesis.
-One more of the technologies may arrive in time to help the first runner, although the world shouldn't count on it
-World will have confronted energy production and energy efficiency at the consumer level
-Electronic items, transportation and buildings will be transformed.
-Economic growth will have been maintained
In this article the author talks about what we can to cut carbon emissions and its future. There were many technologically advanced ways to do this. One way was to reduce electricity use in buildings and make appliances and lighting extremely efficient. Capturing CO2 when there emitted from things such as cars would reduce the need to depend on fuels from the middle east. Another solution was to improve our agricultural practices such as using no-till agriculture. Another solution was reducing are impact on environments such as stopping deforestation. Doing all this will lessen the burden put on our descendants and will return the earth back to its previous state. Although there many problems we need to pave the way for our descendants. Our descendants will not need to use a lot of money and humanity will learn to address collective density and to share the planet.
After reading this article I learned about all we can do to reduce carbon emissions and pave the way for our descendants. Using these solutions and putting them to use will help the environment and it will help us put these things into exercise instead of using bad methods. Much of the money spent on improving this will help us in the long run and every one will benefit. There wont be much to worry about since we wont be affecting the environment as much. We can make sure that we don't go back to bad practices.
