Weather It Is (It's Chilly)

Good Evening:

As mentioned in a previous blog, our temperatures are headed downwards for the next few days as winter-like chill moves south and east into our area.  Temperatures are expected to fall by about 7 C at lower and upper levels, and some moisture will move in as well.

Looking at our three day rain forecast does not indicate a heavy rain, but rain is a possibility and we'll have to see how this plays out during the next few days.

The chilly weather, though, should be followed by an extended period of much warmer weather, which will feel more like summer than spring.

Otherwise, Carbon Dioxide levels continue to rise, and we've passed the 400 parts per million (on average over the globe), which is about 30% higher than before the turn of last century.  Unfortunately, CO2 is one of those gases that increases the heat retention of the atmosphere, as the radiation balance shifts to a higher energy state.  There are those who argue that there is nothing to worry about, but this is based on the argument that in the past changes in CO2 levels did not lead to (or cause) extreme temperatures.  In fact, in the past, changes in solar radiation levels associated with changes in the earth's orbit were likely a big part of changes in earth surface temperatures.  However, in the past there weren't very many people, and CO2 temperatures were not out of "balance" with the underlying amounts of sunlight reaching the earth's surface --  now they are.  The CO2 level. unfortunately, is on the way up.
