At the moment, Australia is undergoing the worst heat wave it’s ever recorded. Pavement has melted, and gasoline evaporates right out of the fuel pump, making refueling a car a challenge. Fires are burning out of control in coastal regions. People have died.
It’s gotten so hot (all together now: how hot is it?) that the Australian weather service has added a new color to its heat map which denotes temperatures above 122 degrees Fahrenheit. That’s 50 degrees Celsius, or half the boiling point of water.
This also doesn’t seem like a problem that will disappear in the near future. Climate scientists believe extreme temperatures are only going to be more prevalent. Due to climate change, many parts of the world could experience more extreme high temperatures and fewer extreme low temperatures, with climate models predicting higher maximum temperatures and more heat waves in the future (Easterling et al, 2000).
By some estimates, these heat waves will increase by a factor of 5 to 10 in the next four decades (Barriopedro et al, 2011). Without countermeasures, these high temps could cause “increased adverse health impacts from heat-related mortality, pollution, storm-related fatalities and injuries, and infectious diseases” (Field et all, 2007).
Some might point out that we have a national service that tells us what the temperature is. Election forecasting virtuoso Nate Silver pointed out in his book “The Signal and the Noise” that it’s such a valuable service, in fact, that a multi-billion dollar service industry in weather forecasting has sprung up from the National Weather Service freely sharing its weather data (it should be noted that these services are providing independent forecasts, not simply repackaging NWS data).
In an age where many phones come pre-loaded with weather apps, does it make sense for a publication to have a network of temperature sensors?
