Dirty Snow Causing Decline In Spring/Summer Snow Cover


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

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?

    Today’s set of postings are an absolute tour de force.

    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’
