I thought I read a few findings that showed that aerosols actually had an overall warming effect rather than a cooling one (
brown cloud over Asia raising temps).
This winter La Nina is correlated in the weather phenomenon but factors like CO2 buildup, what is blowing off the artic and north seas and maybe even cool air from
the brown cloud over China are also factors.
Our general circulation model simulations, which take into account the recently observed widespread occurrence of vertically extended atmospheric
brown clouds over the Indian Ocean and Asia3, suggest that atmospheric brown clouds contribute as much as the recent increase in anthropogenic greenhouse gases to regional lower atmospheric warming trends.
V. Ramanathan, et al, in 2008 noted that the net heating effect of tropospheric
brown clouds over the Pacific alone was about 40 percent.
Our general circulation model simulations, which take into account the recently observed widespread occurrence of vertically extended atmospheric
brown clouds over the Indian Ocean and Asia, suggest that atmospheric brown clouds contribute as much as the recent increase in anthropogenic greenhouse gases to regional lower atmospheric warming trends.

Brown was about to call a snap election, mutterings about David Cameron's leadership were getting louder, and a big, inky black
cloud hung
over them.
In a study published in the journal Science, researchers found that a
brown pollution
cloud over south Asia and the Indian Ocean is largely the result of burning wood and dung for cooking and heating.
This allowed us not only to map the
cloud distribution, but also how it changes from rotation to rotation and also
over longer timescales: our observations were following the
brown dwarfs for more than a year.
UK amiibo collector and resident Nintendo Wire journalist Tom
Brown was fortunate enough to receive both of his
Cloud amiibo a day earlier than the rest of us here
over the pond.
This, even though
over the Indian Ocean basin Ramanathan's team found that sooty
brown clouds enhance heating by half of CO2's claimed effect, not masking it by half as had previously been thought.
In reality, there are a host of both natural and anthropogenic aerosols, ranging from sea salt (the major source of
cloud nuclei
over the ocean) to biogenic aerosols from forests (the «smoke» of the Great Smoky Mountains of the Eastern US) to partially burnt organic materials (the «
brown cloud»
over Asia, generally absorptive / warming) to various sulfur compounds (generally reflective / cooling).

cloud cover and galactic cosmic radiation
over a period of several days.
We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian)
brown cloud — and that air quality measures
over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».
