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...
The most used argument against "global warming skeptics"
The most used arguements seem to be:
1:There is no debate on global warming
2:There is a scientific consensus.
How can you respond to that?
We haven't discussed that climate debate in New York the other day about the motion:
"Global warming is not a crisis."
If it wasn't for the posture of Michael Crighton, the alarmists may have won according to Gavin Schmidt...
Does this Fxy have a global Min?
Heres the question:
Consider the function fxy= x+y+9/x+1/y. Determine all the local max min and saddle points. DOes f have any global maximum points in the region R where x,y>0 Explain algebraically.
So I found only one critical point, 3,1 and found it...

In the early days of Global Warming, the "capo di tutti global warming capi", Stephan Schneider, made his world famous public appeal to commit noble cause corruption:

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...
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...
Poverty is the state for the majority of the world’s people and nations. Why is this? Is it enough to blame poor people for their own predicament? Have they been lazy, made poor decisions, and been solely responsible for their plight? What about their government? Have they pursued policies that...
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...
Based on what I see and read, and in spite of the many attacks on Al Gore's laudable effort to help inform the public, there is a consensus that global climate change is real and caused in part by humans. The forecasts for future emissions cinch the debate.

After reading several papers and seeing gore's movie on GW I'm still searching for solid scientific causal evidence (versus correlations or circumstancial) that anthropogenic greenhouse gases are the cause of global warming in the post-industrial age. I accept we are in a warm epoch...

Quite a while ago, someone posted a flow-chart that showed how the "global warming lie" is repeatedly supported (one bubble being that scientists need funding for their research)

Global warming theory
It is being observed that the earth’s atmosphere is warming up and it is speculated that carbon emissions are the cause. Since the atmosphere is getting warmer it will contain more moisture due to additional evaporation and warmer air holds more moisture than cold air...
This is the follow-up question.
Assuming that there is a warming trend, please give your opinion as to the human contribution to this trend. Once again, I would hope that the opinion is informed and not fanciful or political.

Let's suppose that, as many of the posters here believe, there is a good possibility that global warming is not priimarily caused or even signficantly contributed to by human CO2 emissions. Let's suppose that there is a very good possibility also that CO2 concentrations are not signficantly...

Introduction
The current climate change/global warming debate has become highly political, with some people maintaining that the warming over the last 150 years is due to the enhanced greenhouse effect caused by anthropogenic emission of carbon dioxide and...
If ocean levels go up enough, will they have an impact on the Earth's rotational speed and the Moon's orbital radius? If so what will the effect be? It seems that all these things are tide to one another.

I want to find global extremes of function

M = \left\{[x,y,z] \in \mathbb{R}^{3}, x+2y+4z = a, x,y,z > 0\right\}
I need to show that this is compact. Because I'm in \mathbb{R}^{n} it is sufficient to show it is closed and bounded. Closeness (is this...
Although the titel suggests that the thread is about another planet, the real subject is the forcing character of CO2 greenhouse gas and so it's about global warming and hence it should belong in the Earth forum.
