Persistent Temperatures Far Above Normal in Many Locales
As the earth warms, the weather, at least judging by recent years, has become more stagnant. Snowy places stay snowy longer (ask a Bostonian), and hot places stay hot longer. The following are just a few examples of recent persistent warmer-than-normal weather:
- Nairobi, Kenya has been above normal every day since January 1 and is forecast to stay above normal until at least early May.
- North Pole: Temperatures above 80 degrees north latitude, as measured by the Danish Meteorological Institute, have been above normal all winter.
- Mumbai, India, where the average March temperature is 85 degrees, has been above normal every day since March third, twice topping 100.
- Los Angeles, California has been above normal every day since March 4, setting or tying high temperature records on four days.
Atmospheric Carbon Dioxide Goes Up — and Up — and Up
CO2 measurements on Mount Mauna Loa are increasing, and the rate of increase is increasing. Graphic courtesy of NOAA.
The average weekly CO2 reading for March 22-28, 2015 on Mount Mauna Loa in Hawaii was over 400 parts per million (ppm) for that week for the first time.
At 401.75 for the week, atmospheric carbon dioxide is now five percent higher than it was on the comparable week ten years ago. Carbon dioxide concentrations peak annually in May; Saturday’s reading of 402.94 is at the level of last May and going up at an increasing rate.
