Climate Change

1. How has the concentration of carbon dioxide in the atmosphere changed over the last 100 years ? The concentration of carbon dioxide in he atmosphere has changed a lot in the last 100 years .
2.How have temperature,ice cover, and sea level changed over the last 100 years? The temperature in sea level increased and the ice cover decreased.
3. What is the scientific consensus and does the data support this ?


1.whats the cause of the current global warming trend? The cause of the currentglobal cwarming trend is the human expansion of the greenhouse effect.
2.what are the gasses that contribute to the greenhouse effect? Water vapor , carbon dioxide, methane, nitrous oxide, and Chlorofluorocarbons are the gasses that contribute to the greenhouse effect.
3. What are some consequences of changing the natural atmospheric greenhouse? Some consequences are earth became warmer, regions may welcome warmer temperatures . Warmer conditions will probably lead to more evaporation and precipitation.Clouds drop more rain,sleet,or snow.A stronger greenhouse effect will warm the oceans and partially melt glaciers and other ice rise in sea levels, more co2 will be absorbed by the ocean. You will find warmer plants in warmer areas.
4.Why is solar irradiance not a reason for climate change ? Solar irradiance is not a reason for climate change because the sun has increased its heat energy and sending it to earth. The average amount of energy coming from the sun either remained constant or increased slightly. The top of earth is cooler than the rest of the planet.
