Evidence of Global Warming

ALEJANDRO VILLEGAS

Global Warming and Climate Change

• The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. 

Greenhouse Gasses

• For example, on a molecule-for-molecule basis methane is about eighty times stronger greenhouse gas than carbon dioxide .

Greenhouse Effect

•  Without the greenhouse effect, the planet would be an uninhabitable, frozen wasteland.

World Climate History

• The work largely is an unremarkable retelling of the climate social history of Western Europe over the past two millennia or so, with a rather remarkable conclusion.

World Carbon Dioxide History• The concentration of carbon

dioxide (CO2) in Earth's atmosphere is approximately 390 parts per million by volume as of 2010

Projected Climate Change due to Global Warming 

• This article is about the effects of global warming and climate change. The effects, or impacts, of climate change may be physical, ecological, social or economic.

North Pole Changes

• The magnetic shift may sound dramatic but its slow pace - and the comparative strength of the Earth's magnetic field - means people have little to fear.

Glaciers of the World

• The World Glacier Inventory contains information for over 100,000 glaciers through out the world. Parameters within the inventory include geographic location, area length, orientation.

Greenland Changes

Climate change and global warming are hot topics of discussion all over the world, and these discussions are particularly relevant in relation to Greenland 

Ocean Level Changes

• Key concerns include sea level rise, land loss, changes in maritime storms and flooding, responses to sea level rise and implications for water resources.

Animals facing extinction due to Climate Change • More than a third of the world's

5,743 known species of amphibians are threatened, while 168 species are believed to have gone extinct in recent.

Can we stop global warming?

• Global Warming is a dramatically urgent and serious problem. We don't need to wait for governments to find a solution for this problem.
