Green/SJW dilemma: Climate victims are entitled to AC, but AC heats up the planet

Study: Survivors of wildfires face greater risk of cancer

Climate change has made air conditioning a vital necessity. It also heats up the planet.

INTRO: The world is now 1.1 degrees Celsius — 2 degrees Fahrenheit — warmer on average than it was at the dawn of the Industrial Revolution. But baked into that seemingly small change in the average is a big increase in dangerous extreme temperatures. That’s made cooling, particularly air conditioning, vital for the survival of billions of people.

The devastation of extreme temperatures is playing out right now in several places around the world. A gargantuan heat wave over India and Pakistan, where 1.5 billion people live, is now in its third week. Just 12 percent of India’s population has air conditioning, but even those people are suffering. The heat has triggered power outages, created water shortages, and killed dozens, although the true toll may not be known for weeks.

Swaths of western Europe are also facing a heat wave, with temperatures forecasted to breach 40°C, or 104°F, later this week.

Closer to home, Texas is currently facing a record-breaking heat wave just as six power plants suddenly went offline. The state’s grid operator, the Electric Reliability Council of Texas, asked residents to avoid using large appliances and set thermostats to 78 degrees Fahrenheit between 3 pm and 8 pm.

These searing temperatures are just the latest in a pattern of increasingly hot weather. A heat wave that would have been a once-in-a-decade event in the 1800s is now hotter and happens nearly three times as often. Heat waves that used to occur once every 50 years are now nearly five times as frequent and reach higher temperatures. Heat records are broken so often they barely register as news. In its latest review of climate science, the Intergovernmental Panel on Climate Change said it is “virtually certain” that heat waves have become more frequent and intense across most land areas since the 1950s.

Extreme heat events are also occurring over a wider region of the globe, from the depths of the ocean to the icy reaches of the Arctic. Heat waves are now such devastating events with long-lasting wounds that some countries say they should be named like hurricanes.

But the most severe risks from high temperatures are in places like India and Pakistan, regions closer to the equator that are already hot and have dense, growing populations. They also have less wealth, so fewer can afford cooling when thermometers reach triple digits.

The planet is only going to heat up more, rendering parts of the world unlivable. The most optimistic scenario is that global average temperatures will rise 1.5°C (2.7°F) this century, which will lead to even more intense and frequent heat waves. Right now, though, the world is on course to shoot well past this target.

Regardless of whether humanity gets its act together and drastically cuts emissions of the greenhouse gases that are warming up the planet, billions of people today and into the future desperately need to cool off. Their lives and livelihoods are at stake, making this one of the most urgent technology and policy challenges.

But staying cool amid the heat poses a paradox: The tactics for cooling can end up worsening the very problem they’re trying to solve if they draw on fossil fuels, or leak refrigerants that are potent heat-trapping gases. And the people who stand to experience the most extreme heat are often those least able to cool off.

Solving this conundrum requires untangling issues of equity and justice, as well as developing better tools for cooling beyond just ACs. It also requires rethinking the role of cooling in society. It is not a luxury, but a necessity for living in the world that we’ve created for ourselves... (MORE - details)

There have been a few breakthroughs on the cooling front recently -
1/Painting your house white makes it absorb less heat from the Sun (Whodathunkit?) - silver, like silvered mylar film costs almost nothing and would be better but it looks weird so let's not even think about doing anything sensible that.
2/Insulate the house so less heat gets in - have your AC is just dumping body heat and the hundreds of gadgets you need that generate heat instead of continually pumping heat from the outside out.
