We asked friends of DeSmogBlog to write a letter to their great, great grandchildren about their vision and hopes for their world in 100 years, in the context of global warming. Here's what DeSmogBlog reader Noreen Tsai said:

Dear future sons and daughters of Noreen.

Are the polar bears extinct yet? How much of the Artic is left in existence? Is Santa Clause still a part of your culture, and if he is, where does he live?

Does he still live in the South Pole? IS there a south pole?

Do you know about Hurricane Katrina in 2004 in New Orleans, Louisiana? Is New Orleans still in existence? Or how much of the city is still left?

I hope you make better choices for your world's environment than the choices that my generation made, and I wish you the best in preserving our Earth's finest qualities.

Your mother,

Noreen Tsai
