For instance, the people who routinely get themselves screened for being a carrier for Tay-Sachs disease are a demographic who have an extremely strong historical reason to be worried about Nazi-style dysgenics, and yet, eugenics is exactly what they are doing whenever a couple of them, on learning that they are both carriers, decide to refrain from having children together, or break off their relationship and seek other, non-carrier partners.

In this way, warming or cooling is modulated by decadal-scale variations in albedo, or cloud cover. The cosmic ray explanation for climate change is just a still-controversial theoretical conceptualization as to how clouds are formed.

According to the true energy balance values, the slightly nonlinear cloud forcing would be Cloudiness changes could alone explain the global warming [of recent decades]. March at 9: March at 6: The darker colored area is less intense today than it was a week ago, when it was in the range, ie darker red.

March at 7: Since reading that have often wondered if climate scientists would be able to assess their degree of influence in cloud formation. Similarly, would be nice to get general stats of X increase in cosmic rays due to Y decrease in sunspot activity results in Z increase in cloud formation.

Unless things like this can be measured in some way, over time, everything seems to be just one interesting sounding theory like the CO2 one after another. Yet people find it inconceivable that doubling the level of the second most important heat trapping gas coupled with its positive feedbacks could make a few degrees difference.

Please provide a paper that proves empirically that CO2 causes warming in a convective atmosphere. March at Go and find them. Mean while the rest of us know why the surface is warmer then it would be without an atmosphere.

Since it has been measured and the mechanism is rather simple physics … AndyG55 March at 8: There is only one master denier here.

There is no mechanism whereby CO2 can cause warming in a convective atmosphere.

The shorter wavelength will cause increased evaporation, resulting in more water vapour in the atmosphere. In areas of little cloud cover, drought will prevail. The major problem will be reliable crop production. Skin cancers and eye problems will also sky rocket.This is cool! There’s been this undercurrent in your writings on society and biology for a while now, and I think it’s a radically sane position.

Today during an otherwise terrible lecture on ADHD I realized something important we get sort of backwards. There’s this stereotype that the Left believes that human characteristics are socially determined, and therefore mutable.

The interpretation of average global crop yields is problematic for several reasons. It can be especially difficult to disentangle the effects of changes in technologies, such as improved crop cultivars, from changes in the use of inputs like fertilizer, pesticides, and irrigation.

The table below presents an abbreviated geologic time scale, with times and events germane to this essay. Please refer to a complete geologic time scale when this one seems inadequate. The table below presents an abbreviated geologic time scale, with times and events germane to this essay.

Please refer to a complete geologic time scale when this one seems inadequate. The main focus of this book is on the causation of starvation in general and of famines in particular. The author develops the alternative method of analysis--the 'entitlement approach'--concentrating on ownership and exchange, not on food supply.
