Great American Hubris: Still Wrong

EEK! Was Al Gore wrong?



According to my ultra-conservative source, even the Democratic leaning CNN is starting to doubt the prevailing scientific theory that global warming is entirely man-made.

I'm not a meteorologist, but I've lived long enough to see the climate change. When I was a child, white Christmases were a regular thing an summers were long, dryish and warm. Things have changed.

Left-wing Americans like Gore have promoted the idea that global warming is entirely man-made whereas the right-wing like Dubya have lived in some form of denial.

Gore has a point, he just makes it badly and we all know that Dubya is religiously-driven fucking idiot. You can get details of Gore's film, An Inconvenient Truth here but be cautioned that the film has a tendency to exaggerate: something that Dubya supporters have seized on.

The Earth's been here for 4.5 billion years give or take (or only 6,000ish if you believe Ken Ham and idiots like him) and for a large part of that, it's cooled down from a molten blob into what we see today.

Our home's molten core is still pretty hot and reminds us on occasions when it breaks through the fragile crust and forms massive volcanoe, but for the time that life has been on this planet the majority of our heat has come from our sun.

Due to our orbital eccentricity, solar orbital distance and heat lost to space, the planet's temperature has remained fairly constant over that time: warmer at the equator where it's close to the sun and cold at the poles where it's further away. Yet strikingly, the difference between the warmest and coldest places on Earth is quite dramatic: tens of degrees centigrade. We experience seasonal changes (particularly at the far north and south) because the Earth is tilted a few degrees from vertical.

We know this because life as we know it cannot survive outside of a comparatively narrow range of temperatures. While simple bacteria can survive and even thrive in extremely hot water for example, the higher lifeforms require far more modest temperatures.

Our planet, our home is an ideal temperature to sustain and nourish life as we know it (although this is in part an effect of the anthropic principal).

OK. So what about global warming - is it happening or not?

The majority of Americans, or American politicians anyway, don't want to think so. Such is the state of their denial, they refused to sign up to the Kyoto treaty. (Neither did India, China or Russia). Another excuse suggests that the Kyoto protocol causes economic stagnation and that following such a path allows the non-signatories to get an unfair economic advantage.

But global warming is a fact.

The scientist and the weatherman in the video above both miss (or ignore) an important point about evolution.

Not evolution of a species - evolution of a system.

There are more people alive now than have ever lived and we are changing the planet in ways that we cannot even begin to imagine. Chaos theory tells us a lot about that.

It's not just our cars - it's us! We are net consumers: we're not putting anything back. We're cutting down the trees that scrub the CO2 from the atmosphere and that leaves us with a net imbalance that the planet cannot absorb: it's never had to in its 4.5Bya history.

Sure, the sun is warming the planet. If it should experience a slight blip in output, we'll feel it for sure, but if the concentration of CO2 in the atmosphere continues to rise, the heat energy cannot escape regardless, the planet will warm and climate will change.

We are to blame and no amount of American naval gazing and well-meant bullshit won't help.

Plant a tree and observe your environment.

Mother nature is old and wise - listen to her and listen well because our future depends that we do.

Head over the Lay Scientist to see what right-whinger, God-botherer Richard Littlejohn writes in the Daily Bullshit Mail. Original article here and please try to understand that while there are people just as stupid as Littlejohn, they don't have the opportunity to sell their ideas as facts.
