Question and answer
1.How has global warming affected forest ecosystems? 2.How does global warming affect humans across the globe? 3.What can we do to reduce or reverse global warming?
Basically, global warming is the recent increase in the average air and ocean temperature of the Earth as well as its expected continuationThe main greenhouse gases on earth that contribute to the greenhouse effect are carbon dioxide, [ methane and ozone as well as nitrous oxide and other naturally occurring gases. The levels of carbon dioxide and methane have increased significantly over the
past 650,000 years due to fossil fuels being burned, deforestation and other causesSpeaking of laundry, try air-drying your clothes instead of using a dryer… this can save 700 pounds and $75 a year. • Take care with your appliances. Unplug them when you don’t use them, this saves 1,000 pounds and $256 a year because appliances still use energy if they’re plugged in, even when not in use ]

i really want help with my question and it making me mad that nobody will help
Weegy: I am sorry you have had problems. Please give me your question and I will do my best to answer it for you. User: How much CO¬2 in the atmosphere gives us a comfortable temperature? How much is in the atmosphere currently? Weegy: Humans have increased the amount of carbon dioxide (CO2) in the atmosphere by about 40% over the past 150 years. [ Plugging in our possible climate sensitivity values, this gives us an expected surface temperature change of about 1–2.2°C of global warming, with a most likely value of 1.4°C. However, this tells us the equilibrium temperature. In reality it takes a long time to heat up the oceans due to their thermal inertia. For this reason there is currently a planetary energy imbalance, and the surface has only warmed about 0.8°C. In other words, even if we were to immediately stop adding CO2 to the atmosphere, the planet would warm another ~0.6°C until it reached this new equilibrium state (confirmed by Hansen 2005). This is referred to as the 'warming in the pipeline'. Please wait while find information on your second question. ] User: thank you Weegy: Myles Allen of the University of Oxford, examine the problem from the opposite side: How much more CO2 can the atmosphere safely hold? To keep warming below two degrees C, [ humanity can afford to put one trillion metric tons of CO2 in the atmosphere by 2050, according to Allen and his team—and humans have already emitted half that. Put another way, only one quarter of remaining known coal, oil and natural gas deposits can be burned. “To solve the problem, we need to eliminate net emissions of CO2 entirely,” Allen says. “Emissions need to fall by 2 to 2.5 percent per year from now on.” If these answer have not helped you I will continue to help find what will. ] User: thank you :) Weegy: You are very welcome. I do hope I have been helpful. User: yes you did help Weegy: Have a wonderful day or evening :) And thank you for using Weegy! (More)
