    News Global Warming and Energy Costs: Who Will Bear the Financial Burden?

    1) How come on the PhysicsForums almost no one says “global warming” instead they say “anthropogenic global warming” while the media, and the average person, always refers to it as “global warming”? 2) It is my understanding that if US legislators rule to try and combat anthropogenic global...

    Global warming causes great cooling

    I've seen it before that some people say that global warming will cause or does now cause areas to greatly cool as well. How is this true?

    Is Human Activity the Primary Driver of Global Warming?

    I'm a non-scientist trying to understand a bit about climate science and the state of it. It's mysterious to me why so many people (some on both sides of most debates I see!) seem to treat this as though it were a religious issue and not a scientific one. 1. My understanding is that the...

    Exploring the Effects of Clouds on Global Warming

    Andre, this is mainly concerning your work, especially with your claim that CO2 is not a gas that causes global warming. From what I have gathered (and I hope I don't make a fool of myself by saying this) but you have argued that CO2 levels have risen over periods of cooling in the past...

    Solutions to the energy crisis / global warming problem

    We face an energy crisis, since gas and oil resources are diminishing this century. Oil and gas production follow a bell-curve, and around the middle of the depletion of a gas or oil field, the production of that field decreases yearly. Apart from coal (for producing electricity) and nuclear...
