Autumn/Winter snow cover is rapidly expanding in the Northern Hemisphere, but Spring/Summer snow cover is down. The decline in Spring/Summer snow cover is caused by pollution from places like China. Dark particulates settle on the snow, causing melting. Scientists have known this for years, but blame CO2 because they get paid to do that.
for a given forcing (soot) is twice as effective as CO2 in altering global surface air temperature. This indirect soot forcing may have contributed to global warming of the past century, including the trend toward early springs in the Northern Hemisphere

Soot climate forcing via snow and ice albedos
Dirty snow may warm Arctic as much as greenhouse gases
Tamino blames CO2 for this, because he understands nothing about science.
So is it reasonable to conclude that the planet is actually cooling, given that soot is a warming agent, and global temps have remained flat?
The expansion of winter snow cover seems to be pretty strong indication that earth is cooling
Certainly worth consideration, is it not?
Colorado,
We don’t have to worry about it. China is doing it for us.
Today’s set of postings are an absolute tour de force.
Congratulations
There was also a problem with the satellite sensors under certain conditions.
Arctic snow not darkening due to soot, dust, Dartmouth-led study finds [Oct. 2015]
‘…findings suggest the apparent decline in the dry snow zone’s reflectivity is being caused by uncorrected degradation of sensors in NASA’s aging MODIS satellites’
