If you like Doug Vogt, you'll also like Rolf Witzshe and a few others listed below who concur that we're on our way into an ice age-- maybe very quickly--- Doug is saying 2046... others have said "soon"... essentially the same thing. I'm not sure if it's due to magnetic reversal or solar minimums or sun going nova... as Doug points to... but I only started reviewing my own previous reading on this subject a few weeks ago. The listings below are haphazard as I try to pull my previous references together but there are a few gems in there as well as bad links.
The best one for visitors to this page from Doug's videos is ICE AGE AHEAD-- the only Rolf site I can find that's up right now... http://www.ice-age-ahead-iaa.ca/world_development.html

Doug Vogt's youtube channel-- no text found yet-- but says ice age sheets will occur in 25 years.... similar to OACortez!!!

...although I don't think they're interested because I warned them in 2011 of a coming ice age and there was no response.

Jon Levi and the RESET--- funny how they're using the word reset now-- Global reset, Currency reset, Hillary pointed to reset button with Russia... but Jon Levi refers to civilization resets in history as seen in Tartarian maps, buildings and in mud flood evidence
LINK LATER or find Jon Levi on youtube.

godgevlamste--- on youtube ... points to flat earth crater earth on greater earth-- with invasion from Saturn... another crater far off... and current plans to build disneyland model outside of the crater on the plateau surrounding crater earth... I think he points to an upcoming magnetic reversal too... not sure.

IceAgeNow.com or org... also points to current evidence of oncoming ice age.

Doug Vogt is the best of these... says there will be ice sheets of miles thickness... and that any current tunnel building and survival underground will fail... becuase the ice won't melt for hundreds of years... machines and oxygen will run out... the only chance is to survival at the equator... which is what Witszche says.
