The best action we can take is stop using dirty burning techniques of fossil fuels. We need to do away with, or update all old technology. It's not the fossil fuels, but the fact we are no using efficient clean burning techniques in many places of the world.
The climate always changes. Over very long periods of time...
I see the usage of "climate change" as an intentional misrepresentation of fact. We have very long climatic cycles, and there really is no way to say the changes we see are not natural.
Yes CO2 has an effect on both temperature and absolute humidity, but in both cases it is within the normal parameters of weather changes with a climate system.
What bothers me the mos is they only see what they shine the light on. They only look at greenhouse gasses, then have to amplify their effects with hypothesis after hypothesis.
Land use changes have a dramatic effect on the local microclimates. Aerosols from dirty fossil fuel emissions likel have a more profound effect than greenhouse gasses as well.
When you take several hundred square miles of land, and over 200 years go from almost all natural landscape, to over 80% covered by concrete, asphalt, and building... This is dramatic for the immediate area, and affects the temperature for several miles around as well. What is lost is the natural cooling of evapotranspiration. Rain water that once was absorbed in the ground, and cooled he surface as it evaporated, is now channeled int storm sewers and no longer cools. Nearby meteorological stations can never be correctly "corrected" for this loss of cooling and show an unnatural rise in temperatures as this nearby coolng is lost, and the winds blow the right way...
Soot is probably the worse of the problems. The higher latitude coal plants rain invisible aerosols on the ice. The albedo of the ice is changed, Consier that it wakes very litle so, and i is invisible to the naked eye to change the albedo of ice fro 0.85 to 0.70.
Class...
Anyone know what this means?
Albedo is reflectivity. Changing from a 0.85 to 0.70 means the ice went from absorbing 15% tp 30% , or a doubling in the melting rate...... This is why we are losing the norther ice....
Then as more arctic ocean is exposed, the absorption goes past 50%, where it used to be only 15%.
This is the simple parts of the sciences. I really don't know what people trust the pundits instead of seeking the truth.
