The global organisation that collects and distributed information regarding climate change is the Intergovernmental Panel on Climate Change. Their reports are very long and can be quite technical, but they are very thorough and cover all aspects of climate change.

If you’re wanting a quick overview of the causes and effects then try National Geographic, the NOAA, NASA, the Royal Society or UCAR:

The three primary global temperature records are those maintained by NASA, the Hadley Centre and the University of Alabama in Huntsville.

Trevor's links, and description are very good. Which links you find useful depend on what you already know about global warming. Here's a starter kit?
http://www.rkm.com.au/ANIMATIONS/carbon-... <== here's the physics.
http://web4.audubon.org/globalwarming/im... <== this is why CO2 is a problem.
http://www.rsc.org/images/CA1_tcm18-1379... <== Word doc. Page 6 shows where H2O and CO2 intercept different wavelengths
http://upload.wikimedia.org/wikipedia/co... <== Note that CO2 intercepts a different wavelength than water. In addition, as CO2 warms the oceans, more water evaporates, increasing it's effectiveness.

"Where can I find good information about global-warming ? "
Not here.
In 2011= I came up with a solution called Triple Output that grows 4 times more food per farm per year and My Global Teams experimented using my experiments to see if we could eliminate Global Warming. My Teams were fired upon, so I pulled them out of there. The Country where Global warming was located had problems feeding their people, so I emailed their embassy my Triple Output solution and between July and December 2012. Global Warming was turned off not destroyed, but turned off and now all seasons have returned to normal naturally like it was in the 1970's before Global Warming, Global Command

Ask someone on the East Coast what they think of "Global Warming"!, see if you can convince them of it at -45*
