Why is this, especially as the sun is 40% warmer than back then.

That’s wrong. A logarithmic relationship means than every doubling gives the same result.

In the U.S., I joined the Preventech Foundation the developers of technologies preventing Global Warming.
We submitted these technologies to the authorities, but received no response. Finally, the article in Fresno Bee by Seth Borenstein AP (09/07/06) might convince the Public, that there is no escape from Global Warming. So, we have submitted this technology again! As you may have guessed – no response! History repeats itself – for example, the technology of ‘motioncodes’ which would makes the 9/11 terrorists attack impossible, was submitted one year before 9/11, but again no response!

Actually the scientists receive an automatic electronic form letter, saying “Thank you, we would contact you” – but they never did. Preventive technologies were submitted by different groups of scientists independently from different parts of the world. Ignoring modern technology is the reason why 9/11 did happened.

It appears that the U.S. may not necessarily be destroyed by environmental disaster or by terrorists. Americans could destroy themselves! The mystery – why have Americans decided to self-destruct?

This time we are appealing directly to all citizens. We are looking for a producer to make the multimedia phenomena ‘THE END OF THE LAST EMPIRE’ movie. It would demonstrate technology preventing the END.
The ‘all-in-one’ – drama, horror, suspense and education tool for children, teaching that crime and terrorism will no longer be possible. To avoid the shock and sensationalism the movie will be released as ‘science fiction.’ Once the movie is released, this preventive technology would become every day commodity.

a) There is a solar constant. Check it out on Wikipedia.

b) There is also solar radiation

c) There is also solar variation

d) There is also variation of solar radiation from atmospheric ’stuff’

So, it’s kinda complex.

The chart showing temperature through the ages is a combination of data. Check here for the various data in easy chart form: http://www.inkstain.net/fleck/snaps/mann.gif

One of the reasons for doubt here is that it was thought that the Medieval Warm Period was global. It was mostly a regional or hemispheric effect, as we now know. The later ‘Little Ice Age’ was global in effect and some of the effect was due to volcanic action. There is a great deal of talk about the Thames freezing every year. It actually froze about every 25 years on average and didn’t freeze at all in London after the supports on London Bridge were altered. The little ice age was cold in parts but not as glacial as you might have been led to believe. And some of you have been easily led.

The moral of my story is, be skeptical. Whatever you hear, check it out. The devil is in the details.

As for the present, the global average is the best way to put the whole thing together but doesn’t tell it like it is. All the components tell the story. And they are telling us that the planet is warming, and that CO2 is the major part, and the only part that we have any say over.

And please don’t take fiction for science. You’ll be believing in time travel next.

Heat capacity.

The really short (and Electrical Engineeringish, sorry I’m a PhD EE, and that’s just how I think) version is capacitance induces a phase shift (lag) to a sinusoidal signal. Annually, average heat received from the sun is a sinusoidal signal (the exact amplitude/phase of that signal varies by location). Because of heat capacitance of the ground , the air, and water, the Earth has a pretty high heat capacitance which induces a pretty big phase shift.

There’s another notable effect of capacitance (both electrical and heat). This effect explains why it gets hotter (and colder) in the desert than the coast and more relevantly why the temperature of the earth will lag a step increase in the energy output of the sun. This effect is why “the irradiance trend is flat (or very slightly decreasing) over the last fifty years, which is when the temperature has climbed out of the error band for what we know historically.”

Though I will point out that it cooled in the 70s.

Alright I give up. Why?

This is a really good article from the Coyote Blog on things to consider about global warming. He writes something that I would never have the patience to do myself.
For many years now Ive been increasingly skeptical of all the doom an…
