Pharma Kamagra
Jan 3rd, 2009 by Richard
Pharma kamagra: one of the best early moves that President-elect Barack Obama has made was to appoint physicist John Holdren as his national science adviser — a move that has been cheered by Joe Romm at the influential Climate Progress, and roundly condemned by the professional inactivists like Bjorn Lomborg and Roger Pielke Jr.who are hell-bent on destroying the planet.
Pharma kamagra: if you want to know why Holdren is a great choice, you need to watch as he presents a broad “global climate disruption” overview* for scientists at the The American Response to Climate Change conference. Pharma kamagra: he describes the challenges that we’re facing with succinct and pointed phrases, and it scared the bejesus out of me.
This is just one graph from Holdren’s presentation, and it shows just how inactivists deliberately distort the science.Climate and weather** are actually two different things, and it is much, much harder to predict what the weather will be like on January 27, 2009 than it is to predict what the global climate patterns will be in 2030. Pharma kamagra: and yet, the climate-change deniers argue that if we can’t tell what the weather will be like next Friday, how can we predict 10 or 20 years in the future? They say that the climate models and simulations run on computers are horribly inaccurate.
I call bullshit. Pharma kamagra: this graph lays bare that lie.To test the accuracy of their models pharma kamagra, climate scientists often take them back 100 or 200 years and measure their predictions against observed historical measurements.As you can see from the tight focus from this graph, the computer models are hitting every pitch right out of the park; pharma kamagra.
Pharma kamagra: i can’t say for certain, but I believe this particular simulation also predicts that the arctic will be ice-free during the summer in 2013 or 2014, 60-70 years ahead of the best guesses made just a few years ago.
_________
*Holdren suggests that terms like global warming and climate change don’t convey the catastrophic nature of this problem, and he’s right – pharma kamagra.
**Weather is decidedly short-term pharma kamagra, measured in days and weeks, while climate science measures meteorological phenomena over long periods of time.
