An impressive parade of scientists, meteorologists and grassroots activists assert that humanity is capable of adapting to a changing climate, building sustainable communities without sacrificing modern-day comforts and even reversing some of the damage already done.

Does a solid job of dealing with the problem but with enough originality that it's not an exact duplication of the Gore film.

A straightforward, quietly persuasive primer on the climate-change crisis.

A more diffuse and prettier case for global calamity that accents the positive and stresses the possibility of reversing the planet's headlong rush to extinction.

Unlike Gore's movie, which focused largely on what Americans had done to cause the problem and what they could do to fix it, The Great Warming treats global warming as a global issue.
