They are not just looking at a couple hundred years of weather data. Climate scientists have investigated warming in the earths past and have a very good understanding of what caused warm periods in earth history.
For example past warming events have been caused by cyclical deviations in the earths orbit exposing it to more sunlight, or increased solar activity. However these are not the cause of the current warming because the earths orbit is currently stable and will be for another 16,000 years and solar activity has been measured and has been shown to have declined during this current period of warming. The rate of which the planet is currently warming is also far higher than previous natural causes.
Absolutely the climate changes naturally. But does not preclude mankind from changing the climate. The current warming does not have a natural cause
Just because CO2 only makes 0.4% of the atmosphere, does not preclude it from having a massive impact on the planet. To suggest otherwise is just showing ones ignorance.
No other man made issue is as serious or will have the same impact on the planet and to humanity as man made climate change. Again to suggest otherwise is just a deflection.

What else am I suppose to say to your logical fallacies. You brought up North Africa being a desert (and I said Africa, not North Africa) to imply that droughts occur naturally. I'm pointing out that doesn't prove anything. Its like saying human being die of natural causes therefore can not die of man made causes like.
CO2 increases temperature, higher temperatures evaporate more water in the earths soil, less water in the earths soil will result in more droughts as plants and crops need that water to live.
Is that clear enough for you?
