Interesting

Some articles on how the IPCC report on global warming (the one Gore won his Nobel Prize for) significantly exaggerated the effects of human-produced greenhouse gases, and how Alaskan glaciers are rebounding for the first time since they began retreating.

Honestly, the more I read about global warming from real scientists, not the sensationalists and the scaremongering of Al Gore, the more I begin to believe it's all horseshit. Earth has been warming for over 200 years. Anybody remember learning about the Little Ice Age back before America was a full independent country? Of course not, cause then you'd have acknowledge that we've seen a warming trend over a much longer period of time than humans have been pumping greenhouse gases into the atmosphere. Also, CO2 is not the most significant greenhouse gas. Take it from someone who had to get infrared astronomy data from a satellite instead of ground-based telescopes because H2O absorbs infrared radiation. Yeah, water is a major greenhouse gas. Keep in mind also that water in its liquid and solid forms has a negative warming effect:

-Most of the sun's energy is in the visible part of the spectrum (very little IR)
-Earth absorbs some of this radiation and re-emits it in the IR
-The greenhouse gases absorb this re-emitted radiation and re-emit it at longer IR wavelengths
-Ice and water reflect the sun's radiation, keeping it from being absorbed and re-emitted as IR radiation
-This radiation is allowed to pass through the atmosphere undisturbed and does not heat our planet
-Any positive growth in glaciers we see will begin to put downward pressure on global temperatures

Anyway, that was a long enough brain dump for now.
