I saw a report in the news that the average global temperature is expected to rise by 9 degrees in a rapid time frame. Massive flooding, drought, and violent weather conditions are expected in areas formerly immune to such occurrences.
“The earth’s average temperature is set to increase 9°F (5°C) by 2100.”

Preppers truly need to plan for a self-sufficient water supply. They need to plan for shelters that are designed to insulate against extreme heat and cold.
Building with designs and materials that produce a comfortable natural mean temperature that requires little heating and cooling adjustment is the aim. It can be very practical to satisfy this requirement once consumers specify their needs.
You cannot accept traditional building design and construction standards to satisfy emerging needs for sustainable living.
If you think you can avoid the heat, read this story that says if you live within 1,000 miles of a major city, you are likely to be affected by the cities’ heat and pollution output.
“Cities Are Making The Entire Planet Hotter
The collection of people, buildings, and cars that create a city put out a lot of heat--and while they use energy more efficiently, they’re still contributing to the rising temperature of the planet.
Anyone who lives 1,000 miles away from a major city probably thinks they’re immune to all the side effects--positive and negative--of city life. They’re wrong. A study published in Nature Climate Change recently found that waste heat from cars, buildings, and other heat sources in cities across the Northern Hemisphere trigger high winter temperatures, even in remote areas.
You’ve probably heard of the urban heat island effect--a phenomenon that occurs when retained heat is re-radiated by buildings and pavements. This is different. The study, which comes from researchers at University of California, San Diego; Florida State University; and the National Center for Atmospheric Research, looks at heat emitted directly from cars and other sources.
PhysOrg explains how the scientists conducted their research:[The authors] analyzed the energy consumption--from heating buildings to powering vehicles--that generates waste heat release. The world’s total energy consumption in 2006 was equivalent to a constant-use rate of 16 terawatts (one terawatt, or TW, equals 1 trillion watts). Of that, an average rate of 6.7 TW was consumed in 86 metropolitan areas in the Northern Hemisphere. Using a computer model of the atmosphere, the authors found that the influence of this waste heat can widen the jet stream.
That means waste heat from urban energy consumption can spread far and wide. So if humanity wants to curb the disturbing recent patterns of winter warming--and all the cascading problems throughout the year that occur because of it--we need to focus on urban energy consumption. Slowing energy consumption won’t make a big dent in global climate change (an average worldwide temperature increase of 0.02 degrees F is from waste heat), but it will make a difference regionally."
