New paper: man-made aerosols have had a net cooling effect since beginning of industrial revolution

Watts Up With That?

From Smith et al. 2004 "Historical Sulfur Dioxide Emissions 1850-2000: Methods and Results" -PNNL Historical Sulfur Dioxide Emissions from 1850

More aerosols, means more clouds, which means cooler temperatures. Now that we are cleaning up aerosols worldwide, this may explain why the Earth is getting slightly warmer – more sunlight reaches the surface

A paper published today in Science claims the transition from “pristine” to “slightly polluted” atmosphere at the beginning of the industrial revolution in the 18th century had a “dramatic aerosol effect [of increasing] clouds” over the oceans. According to the authors,

  1. ”this may explain why the Earth is getting slightly warmer ”

    How can anybody know that; the planet is ”SLIGHTLY” warmer…?

    1] on 99,9999999999999999% on the planet’s surface area, nobody is monitoring the temperature
    b] atmosphere is NOT as human body; if under the armpit is warmer by one degree = the whole body is warmer by that much; In nature the temp is different on every 50m and changes every few minutes, INDEPENDENTLY

    1] where is monitoring only for the the warmest minute in 24h and ignored all the other 1439 minutes, in which the temp is not changing accordingly to the ”hottest” minute

    Which means: ”SLIGHTLY WARMER” is a very, very loaded comment!!! b] nobody knows in plus/minus inaccuracy the overall GLOBAL temp by 2-3C, to save his / her life… what is ”slightly”? The truth always wins on the end!!!
