I've read that the highest recorded temperature is highly disputable, because the man who recorded the temperature was nothing more than a helping person (the main man was sick). Also because other recorded temperatures on that day in Libya and surroundings were much lower.

Probably the most likely recorded temperature is that in Deat Valley which was 56,7 degrees Celsius.

By the way, also highest recorded temperatures of Europe (Seville, 50 degrees) and Australia (cloncurry, 53 degrees) are not right.

I am little bit of a climate/wheater freak, sorry;)

Earth is the only planet in the Solar System to have water in its three states of matter: as a solid (ice), a liquid (sea, rain, etc.) and as a gas (clouds).

Just a note,
not to do with the Earth as such, but Pluto as of today is no longer a planet.
So our solar syatem is now reduced to 8 planets.

Earth is the only planet in the Solar System not to be named after a mythical God.

Utrecht, you will get along very well with Beerman as he is a weather freak too. He loves this site:

I saw this on the news this morning. I'm in mourning for Pluto. As far as I'm concerned - it's still a planet.

A 1999 study showed that African dust finds its way to Florida and can help push parts of the state over the prescribed air quality limit for particulate matter set by the U.S. Environmental Protection Agency. The dust is kicked up by high winds in North Africa and carried as high as 20,000 feet (6,100 meters), where it's caught up in the trade winds and carried across the sea. Dust from China makes its way to North America, too.

Actaully clouds are liquid... no? And didn't they add three planets? I thought I heard they added three, and kept pluto. I have no idea where I read that - maybe it was a dream .

Earth Fact: Over the last 50 years we (as humans) have released endocrine disruptors throughout the world that are having fundamental effects on the immune systems and reproductive systems of all life. The worst part of all this? No one gives a damn.

Quoting "Derrick Jensen"

As forests are felled, rivers poisoned, soil toxified, as we see beautiful wild places we love destroyed, as we watch our grandparents, cousins, brothers, sisters, lovers, children, ourselves wasting away from cancer, the whole culture tells us time and again the same message: you cannot surive without this culture, without civilization.

They kicked Pluto out and wouldn't reclass three other objects as planets.

Pluto has been downgraded to a dwarf planet rather than a major...
Astronomers strip Pluto of its planet status

Here's what I found on the 3 new planets:

Ahhh, so I wasn't dreaming... mearly outdated. Well I think it's interesting that there is even a debate on whether Pluto is a planet... who cares? A big ball of frozen rock... think losing it we will lose our status in the Universe?
