Heat: Altering the future

Heat is altering the future on this planet. If you haven’t yet personally experienced the effects of global warming, you surely must have heard about them. July, like June, has produced record-breaking temperatures world wide. If that’s not bad enough, the future will clearly get worse every year, according to almost all scientists who study the phenomena.

Unless we, collectively, do something about it. The sooner we act, the quicker this trend will slow down. By acting I mean stopping putting carbon into the atmosphere. Stopping, not reducing. Every additional atom of carbon dioxide or methane in the atmosphere makes thing a bit worse. Regardless of its source.


For example, Phoenix, Arizona, has had 31 straight days in June-July with the temperature at or exceeding 110F (43.3C). For reference on the human impact of this temperature, NOAA (the National Oceanic and Atmospheric Administration) has a handy chart showing the relationship between temperature, humidity and human survival. Note that 110F with only 36% humidity makes sunstroke, heat cramps or heat exhaustion likely and heatstroke possible with prolonged exposure and.or physical activity. Even at 10% humidity those problems are possible. But for 31 straight days? Next year it might 40 straight days.

Of course Phoenix is a desert city and its humidity tends to be low in summer but the point is that the annual number of really hot days is increasing faster than seems possible just a few years ago. Kim Stanley Robinson’s prophetic book “The Ministry of the Future” begins with a story about a (fictional) city in India that suffers a devastating heat wave that kills most of its population. Review that NOAA chart for your own location.

All of this is because we continue to pump more carbon into the atmosphere, day after day. That has to stop if we are to survive long term. If we are to stop the boiling.

My blog in May, written by Lucy Reed, focused on what you personally can do to relieve climate stress. I’m focusing here on the broader picture of what must be done to stop climate change. There are three main objects of needed effort: government; polluting industry and us.
