Question

What do scientists say about global warming and the greenhouse effect? (FOR CLASS PROJECT)?

Answer 1

they said stop sending money, it`s a scam. I`m done with my home work, so do your own

Answer 2

latest headline.

follow the money trail

'Coldest winter in 100 years'

China battles the freezing weather that has stranded millions

Answer 3

Its nothing but the emmission of green house gas lead to ocean warming the ocean is warmed due to the dissolution of CO2 in it more greenhouse gas contains more CO2 so more evoporation of Ocean water so more rain and more snow during the winter.

Answer 4

this quote from the American Geophysical Union pretty much sums it up.

"The Earth's climate is now clearly out of balance and is warming. Many components of the climate system—including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons—are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956–2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate."

or another quote from The American Association for the Advancement of Science

"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society."
