What is a probable cause of the abrupt climate change in the recent decades?
carbon dioxide and other greenhouse gases in the air
aeolian and volcanic dust
abyssal ocean circulation
orogeny and continental uplift
In recent tens of decades, observations have shown that the stratosphere has been cooling, while the troposphere and the earth's surface have been warming.
What could be an explanation for this apparent coupling effect between the stratopshere and the space beneath the stratosphere?
Because of the albedo effect, the reflections of the solar radiations by the constituents of the stratosphere. The implies how critical the angle from the sun effects the albedo value and lower sun angles.
How much extraterrestrial dusts might have been reaching the earth's atmosphere each year?
What would be a probable impact of such dusts falling into the ocean?
Almost 200 tons/year and are probable iron rich!
Microorganisms needs iron for survival.
If we had to much dust particles in the open water, it would raise the amount of carbon on the ocean floor.
But too much iron could be deadly
