The World is Getting Smarter

I'm not going to digest this one for you. :P
If you have free time take a look on this lengthy and interesting article:
THE WORLD IS GETTING SMARTER
AT LEAST, BY JAMES FLYNN'S CALCULATIONS


The site containing the article (more intelligent life) seems to be very active and it is one of the best sites I've come across lately.

Imagine



Imagine there's no Heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today

Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace

You may say that I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as one

Imagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
Imagine all the people
Sharing all the world

You may say that I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will live as one

Climate Change 2007 - Understanding and Attributing Climate Change

The Intergovernmental Panel on Climate Change (IPCC) will be releasing their 4th Assessment Report on climate change on 17 November 2007.
The information is already available in their website for consultation and that allowed me to get this info from the Working Group I Report "The Physical Science Basis" - (Section 9 - Understanding and Attributing Climate Change):
Executive Summary

Evidence of the effect of external influences on the climate system has continued to accumulate since the Third Assessment Report (TAR). The evidence now available is substantially stronger and is based on analyses of widespread temperature increases throughout the climate system and changes in other climate variables.

[...]

Human-induced warming of the climate system is widespread.

[...]

It is likely that there has been a substantial anthropogenic contribution to surface temperature increases in every continent except Antarctica since the middle of the 20th century.

[...]

Surface temperature extremes have likely been affected by anthropogenic forcing.

[...]

There is evidence of anthropogenic influence in other parts of the climate system.

[...]

Analyses of palaeoclimate data have increased confidence in the role of external influences on climate.

[...]

Overall consistency of evidence. Many observed changes in surface and free atmospheric temperature, ocean temperature and sea ice extent, and some large-scale changes in the atmospheric circulation over the 20th century are distinct from internal variability and consistent with the expected response to anthropogenic forcing.

[...]

Remaining uncertainties. Further improvements in models and analysis techniques have led to increased confidence in the understanding of the infl uence of external forcing on climate since the TAR. However, estimates of some radiative forcings remain uncertain, including aerosol forcing and inter-decadal variations in solar forcing.
More about this when the news agencies start reporting it. :)
