    Why it's too late to stop global warming

    I virtually agree with your lengthy post above Mech Engineer. But the arguements go deeper. you refer to the UHI effect, this has been taken into account in a lot of calculations but the argument goes on if the adjustments are correct...who knows, as you say records are comapritively extremely...

    Why it's too late to stop global warming

    I missed this thread ! One mustn't forget there are two vastly different opinions on GW a) that it is man made and b) that it is part of the historical cycle that has gone on over the evolution of the earth. You will find references to both sides abound and they tend to be rather polar. i am one...

    What produce the earth magnetic fields ?

    I just happen to have a copy of the Scientific American to hand, just as well because this isn't my field at all! "Probing the Geodynamo". It would appear that the mantle revolves faster than the inner and outer core. The upwelling of hot buoyant parcels of liquid iron towards the mantle...

    Flow of Time - What Effect Does Speed Have on Electron Orbits?

    Please excuse my lack of knowledge in this subject, my assumption may have already been answered ! "speed" is measured relative to "something" i.e you are driving along a motorway at 70mph you are traveling at 70mph faster than the surface of that road. If two cars are heading towards each other...

    Key Argument for Global Warming Critics Evaporates

    Thank you for that Andre, a fascinating excerpt from the RS you have found there. After agreeing with just about all you say I have to be a little contentious with "what if the natural cycle is positively affected by human intervention?" There are so many "ifs" that one can only make best...

    Key Argument for Global Warming Critics Evaporates

    Hi Andre, I quite agree with your analysis of the situation,however "to answer a question one has to first know the question" which too often is not addressed. "Is the world warming up"? relative to what time scale? If the period referred to is the past 10 years then the answer is probably...

    Oxygen to Sulphur: Paul D's Theory

    I am not sure if this question is even in the correct thread but please bear with me. I have a theory about the smell of sulphur following lightning strikes or extreme electrical activity in the atmosphere. (this has been quite well documted). Would it be possible for a very high voltage to...

    What Causes Ball Lightning and How is it Controlled?

    I am in the final stages of writing a paper on a Ball Lightning event earlier this year in Guernsey, Channel Islands, UK. The event occurred in February, late evening during a cold NE airstream with occasional snow showers. It appears to have been precipitated by an aircraft contacting a large...

    How did y'all find Physicsforums?

    I found my way here through a link posted on UK Weather World, absoluteley fascinating and enlightning forum. Now spend even less time doing what I should be! :devil: but thoroughly enjoying it. Regards
