Global Warming is the recent sudden (over 200 years) way the Earth is getting warmer. The word 'global' means 'worldwide' and the warming is of the atmosphere, the oceans and the surface of the earth.

The earth has always warmed and cooled in the past, but this has always taken thousands of years to occur. When we talk about Global Warming now, we are referring to the unprecedented changes in temperature since the Industrial Revolution.

According to the Intergovernmental Panel on Climate Change (IPCC), temperatures, averaged over all land and ocean surfaces, have warmed roughly 1.33 degrees F (0.74C) over the last century, (see page 2 of the IPCC's Climate Change 2007: Synthesis Report Summary for Policymakers Link below.). More than half of this warming, about 0.72F (0.4C), has occurred since 1979.

Answer:

Global Warming, Global Climate Change and other terms are used to describe the observed and scientifically verified changes in the Earth's temperature, climate and weather patterns over the past several decades. The cause of this change is attributed to the manmade increases in several heat retaining gases collectively referred to as Greenhouse gases which include carbon dioxide and methane which result from human activities and emissions which include the use of fossil fuels, agricultural practices and deforestation.

Answer:

Global warming: Global means all over the world. Warming means getting hotter.

It is the way the earth is getting warmer, because of extra greenhouse gases that man is adding to the atmosphere. These extra gases (carbon dioxide and methane, mostly) are making the earth warmer. This warming is causing the climate to change.

The early signs of climate change are showing up across vastly differing landscapes: from melting outposts near the Arctic Circle to disappearing glaciers high in the Andes; from the rising water in the deltas of Bangladesh to the "sinking" atolls of the Pacific. Reports from a Warming Planet takes you to parts of the planet where global warming is already making changes to life and landscape, and demonstrates how climate change is no longer restricted to scientific modeling about the future. It's happening now.
