Global dimming is the gradual reduction in the amount of global direct irradiance at the surface of the earth.
It is a concept that has been observed since systematic measurements began in the 1950s, and the name was coined by Gerry Stanhill, an English scientist working in Israel, who was also the first to spot these effects.
He compared Israeli sunlight records from the 50s with the current ones and was astonished to find a 22% drop in the sunlight.
ntrigued by the records, he investigated the phenomenon further and found the same story almost everywhere he looked, with sunlight falling by about 10% over the US, 16% in parts of the British Isles and by up to 30% in parts of the Soviet Union.
Measurements taken between the 1960s and the early 1990s, in collaboration with a wide range of data and independent studies, have shown that there was a substantial decline in the amount of the sun’s energy reaching the surface of the earth, hence global dimming.
Global dimming is believed to be caused by the increase in particulates like sulfate aerosols in the atmosphere, all of which are attributed to human actions. Global dimming, surprisingly, has an opposite effect to global warming as it produces cooling effects, so in essence, global dimming is beneficial to the environment, although it brings about elements of literal darkness on earth. The effects of global dimming vary by location, with some areas being badly affected than others.
For instance, the northern hemisphere saw much more significant declines with reductions of between 4% and 8% between 1961 and 1990. Since then, Europe and North America have seen partial recovery, or
global brightening, with China and India seeing further, although regionally mixed declines.
Effects:
As a result of the reflection of solar energy away from the surface of the earth, the water in the northern hemisphere is becoming colder. This is resulting in slow evaporation and the generation of far lesser water droplets. As a result of these, there is a reduction in the amount of rain reaching these areas of the globe causing drought and famine situations. The tragic consequences of these are miserable lives, disturbed marine life and deaths due to starvation
It has been established that the drought and famine of The Sahel, which killed thousands in sub-Saharan Africa in the 1970s was largely due to global dimming.
Again, as a result of global dimming which reflects solar energy and heat that was meant for the planet’s surface, the overall temperature on land goes down.
Global dimming means there is a blanket in the atmosphere which prevents all the heat from the sun from reaching us. This results in colder days and an overall change in global temperatures.

So when I remove the EGR valve on my F250 6.7 and spew those particulates into the atmosphere - I am doing my part to stop global warming.
