After hanging afar all day, a moist and patchy-dense fog has finally settled itself down deeply here along the north coast — according to WunderBlog, ‘zero’ percent chance of rain for this locale, so it’s all bad-ass marine layer out there.
No rain forecast until Monday.
Although fog is way-normal for this area year-round, it just seemed out-of-place this afternoon, no storm clouds.
Even with no rain, the air is still carrying/holding a lot of moisture — if outside for any length of time, you’ll get soaked. A deceptive soaking…
And of rain, today the NWS released preliminary rainfall totals for October, and my little spot (Eureka/Arcata Airport) showed last month we were 38 percent of normal, and way-down from October 2014. Early in the season yet, and we had clear weather into late October, too.
The last three weeks have been pretty wet, though, mostly on-and-off, drizzle-type rain.
Aided and abetted by an El Niño event, rain/snow should soon be on the way — the whole scenario heating up, and choking up. Last week, it was announced daily average concentration of CO2 in the air topped the infamous 400 ppm, recorded at Hawaii’s Mauna Loa Observatory.
Science writer Bob Henson, again at WunderBlog this afternoon, detailed the situation, with some notable points in our own personal scenarios:
On November 12 it rose to 401.64 ppm, and it’s quite possible that we’ll never see another day in our lives with the daily Mauna Loa CO2 reading below 400 ppm.
Ordinarily, we might expect one more northern summer with CO2 values below 400 ppm, but El Niño could prevent that.
A strong El Niño event, like the one now under way, tends to produce drought in some of the world’s most heavily forested areas, such as Indonesia.
Averaged across the globe, this temporarily reduces the total amount of CO2 soaked up by Earth’s vegetation.
In addition, the large fires common in drought-stricken areas pour even more CO2 into the air.
Based on this prospect, Ralph Keeling, who directs the CO2 measurement program at Mauna Loa for the Scripps Institute of Oceanography, made a fairly bold prediction on October 21: “By sometime in the next month or two, CO2 will again rise above 400 ppm. Will daily values at Mauna Loa ever fall below 400 ppm again in our lifetimes? I’m prepared to project that they won’t, making the current values the last time the Mauna Loa record will produce numbers in the 300s.”
