Dust is Warming Atlantic, Not CO2

Here you go, warmaholics. And yes…I found the global warming ‘disclaimer’ statement in the article (see highlighted last sentence), since LiveScience is obviously part of the establishment still trying to prop up this dumbass theory.

The last highlighted sentence below does let slip one little thing, while still trying hold on to the AGW pipedream: Climate systems are complex, and current models (that show us boiling ourselves due to capitalism) don’t and CANNOT take into account EVERY variable needed to accurately predict future climate. If dust storms were a missing variable, how many more missing variables are there? In other words, we’re not smart enough yet to predict 100 years out. We can’t even predict the weather five days out accurately!

Dust Responsible for Most of Atlantic Warming

The warming of Atlantic Ocean waters in recent decades is largely due to declines in airborne dust from African deserts and lower volcanic emissions, a new study suggests.

Since 1980, the tropical North Atlantic has been warming by an average of a half-degree Fahrenheit (a quarter-degree Celsius) per decade.

While that number may sound small, it can translate to big impacts on hurricanes, which are fueled by warm surface waters, said study team member Amato Evan of the University of Wisconsin-Madison. For example, the ocean temperature difference between 1994, a quiet hurricane year, and 2005's record-breaking year of storms (including Hurricane Katrina), was just 1 degree Fahrenheit.

Evan and his colleagues had previously shown that African dust and other airborne particles can suppress hurricane activity by reducing how much sunlight reaches the ocean and keeping the sea surface cool. Dusty years predict mild hurricane seasons, while years with low dust activity — including 2004 and 2005 — have been linked to stronger and more frequent storms.


This adjustment brings the estimate of global warming's impact on the Atlantic more in line with the smaller degree of ocean warming seen elsewhere, such as the Pacific.

Of course, this doesn't discount the importance of global warming, Evan said, but indicates that newer climate models will need to include dust storms as a factor to accurately predict how ocean temperatures will change.
