Where is the go Kunming gallery??

I'm looking for the 1945 photos of Kunming, many of these photos shows how clear and clean the air was.

@ HFCAMPO.. I clearly remember dozens and dozens of condensation trails in the skies of Atlantic Canada way back in the early 70's covering the whole sky, its nothing new. If they last it's because the vapor has changed to ice crystals. If vapor doesnt change to ice crystals it evaporates much quicker.

But I do agree it does have an adverse effect on climate, similar to seeding clouds, but so does the relentless pollution that's pumped up into the stratosphere from other sources.

HFCAMPO quote.."Why there were no Contrails (Chemtrails) that lasted for hours back in the 60s, 70s, 80, and 90s."

Agree with bobbles on all points, especially the layman's term "Warming"

Climate change is more accurate.

In time mother earth will cleanse itself from the parasite we call "humanity" although by then we'll be a thin layer of sediments in it's geological history.

I will be driving to Lijiang- Jinsha (Yangtzy) valley and return to Kunming sometime in April.
I'll be scouting for paragliding sites, mainly camping.

Will consider accommodating your travel dates and destinations to share costs.
You can bring a lot of gear/ luggage. .
