Clouds reduce the energy at the surface, i.e. they currently cool the climate.
The DIY way to demystify „greenhouse gas” claims, Part 6
Are you feeling helpless when trying to assess the veracity of “climate doom is looming” claims we are permanently bombarded with? Don’t give up trying to understand the relevant basics, there is a rather simple way to get an idea about what this is all about. Even without a scientific background, most people have at least a good common sense. And that’s all it takes to get a grasp of how energy flows back and forth between earth’s surface and the skies.

The decisive faulty assumption of current climate science
When discussing climate topics related to the role of the so-called “greenhouse gases” and the distinction the IPCC makes with respect to “forcers” and “feedback amplifiers,” one inevitably stumbles across the question about what is the difference between both. In fact, the molecules from the “nobility” of the greenhouse gases – CO2, N2O and methane complemented by a few minor gases – can pick up very specific types of photons from the infrared spectrum emitted by earth’s surface and re-emit another photon with comparable wavelength some time thereafter. The absorbed photon energy will raise the internal energy of the molecule by initiating mechanical oscillations between its components. Scientist say that such a molecule has been “stimulated”. In this context, it has to be emphasized that under near-surface conditions, a re-emission will take place only for a minuscule fraction of the intercepted photons. Most of the photon energy absorbed by stimulated molecules will simply be converted to kinetic energy due to collisions with the surrounding air molecules, resulting in an insignificant temperature rise of the surrounding air. And only half of the few IR photons that happen to be re-emitted will be oriented downwards to the surface while the other half will follow an upward trajectory. This small fraction of a fraction is alleged to bring down the balance of our climate system. Such allegations simply ignore the fact that our climate system has proven to be resilient against all sorts of catastrophic events including monster volcanic emissions or the impact of the mighty “dino-killer” asteroid some 64 million years ago. But this is not the whole story.
