Question and answer
5. What does polar ice do to the sunlight that strikes it? How does this help reduce global warming? What is happened to the sunlight energy that strikes ocean water? How does this speed up the
melting of ice?
Shiny polar ice reflects 90 percent of the sunlight that strikes it back into space. Liquid water, on the other hand, retains 90 percent of the energy it receives. The more energy it absorbs, the hotter it gets. [ The hotter the water, the faster the ice melts. The melting ice frees a relatively warm layer of Atlantic water, which, as Ruth Curry from Woods Hole Oceanographic Institute told
"Time," rises into the atmosphere and releases more heat. Read more: What Are the Causes of the Melting Polar Ice Caps? | eHow.com ]

What are governments doing to protect endangered species?
Weegy: Sir/Madam, The Endangered Species Act (ESA for short) was enacted by Congress in 1973. [ Under the ESA, the federal government has the responsibility to protect: Endangered Species - species that are likely to become extinct throughout all or a large portion of their range. Threatened Species - species that are likely to become endangered in the near future. Critical habitat - vital to the survival of endangered or threatened species. to read more about it log on to this site: ] User: thank you Weegy: you are welcome. (More)

What is causing global warming? Why would a power plant employee oppose the idea of Global Warming?
Weegy: Human activity is causing global warming. [ A power plant employee would probably oppose the idea of global warming because if actions were taken to try to stop global warming, many power plants would be shut down, causing many of the employees to lose their jobs ] (More)

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)
