New Weekly Record High for Carbon Dioxide Established at Mauna Loa.

From the Mauna Loa Carbon Dioxide Observatory:

Up-to-date weekly average CO2 at Mauna Loa

Week beginning on April 7, 2019: 413.13 ppm
Weekly value from 1 year ago: 409.46 ppm
Weekly value from 10 years ago: 389.50 ppm
Last updated: April 14, 2019

The increase over 1 year ago is 3.67 ppm.

The value recorded here is the highest weekly reading ever recorded.

This year has been somewhat anomalous, with a kind of plateau lasting through much of February and March, after the previous high ever recorded, 412.41 was recorded on February 10. Values ranged between 412.41 and 410.98, with an average of 411.98 since February 10, not including this week.

I began to suspect an early Northern Hemisphere spring; each spring the yearly maximum is reached for these readings.

In 1976, the first full year for which weekly data is available, the annual peak, 335.30 ppm was reached on May 23.

In 2016, it occurred on April 10.

It does see as the climate condition worsens while we all wait for the wind and solar nirvana that never comes, that the Northern Hemisphere spring, which dominates the carbon dioxide annual cyclic readings owing to the bulk of land mass being in the Northern Hemisphere, should be arriving earlier each year, but February seemed a little extreme, even to me, a person who has come to expect the worst.

The peak in 2018, 411.85 arrived comfortably late, May 13.

We do not know when the peak will come this year.

The increase over the same week last year is 3.67. Since 1975, 2254 such readings have been recorded. The increase represented here, again, 3.67, is the 45th worst ever recorded, placing it in the 98th percentile for "worst ever." The absolute worst ever, 5.04 ppm was recorded in the week of July 31, 2016, by comparison with the reading at the end of July in 2015.

If any of this troubles you, don't worry, be happy. I read here recently that the Wisconsin legislature approved a 5 fold increase in solar installations in that State. This has nothing at all to do with climate change of course, since all the solar energy installations installed over all of human history to endless cheering have done nothing to address climate change, although it should create lots of jobs for people sweeping snow off of solar cells in that state.

In any case, new solar farms in Wisconsin should be good for migrant workers, establishing a winter business, snow sweeping. If that doesn't work in Wisconsin, we can always burn more dangerous natural gas when snow is on the ground and on the solar cells and go a long way to eliminating, um, snow.

I hope you're enjoying your Sunday afternoon.

1. So, even Hawaii

We do not know when the peak will come this year.

I am enjoying reading your update on CO2. It's still morning on the west coast. Beautiful, clear day, highs in low 80s.
