Cold Weather in Mexico

For the last few days we have been wondering what the down side of global warming is. Despite being 19* north latitude, we are 7,900 feet above sea level in a high mountain basin and it gets quite cold here at night. Two nights ago it was 2*C; that's about 36.5*F outside. What's worse is that our homes do not have central heating and they are made out of concrete so they can get quite cool. The other night it was 10*C or 50*F inside our house. I understand that this is unseasonably cool for Mexico City. Such temperatures do not usually arrive until December or January (that is something to look forward to). Fortunately, we found compressed fire logs for the fireplace at the Costco and the Ruizes lent us several blankets. The Ruizes will be taking us to a market that specializes in blankets this next Tuesday so we can find some warm coverings. The days warm up a bit but the air is noticably cool.
The good thing is that the cool has also supressed the smog a bit and for the last couple days, we have had a good view of the volcanoes. The top picture is of both Itza and Popo from our veranda. The next is of Itza, taken from near the retreat centre, and the last is of Popo letting off a little steam. Yes, that is snow on the mountains and that snow is there year round.
