Save the Keeling Curve!

Climate change's most iconic research project is in danger--a victim of budget cuts in an era of increased government belt-tightening. The Keeling Curve is a measurement of the concentration of carbon dioxide in the atmosphere made atop Hawaii’s Mauna Loa, begun in 1958 by Dr. Charles Keeling. It is the longest-running such measurement in the world. The curve was instrumental in showing how human emissions of carbon dioxide were steadily accumulating in Earth's atmosphere, and raised awareness that human-caused climate change was an ever-increasing threat to the stability of our climate. After Keeling's death in 2005, the measurements were continued by his son, Ralph F. Keeling. Support from NSF, NOAA and NASA is being diminished or withdrawn, and Keeling has turned to crowd-funding to help raise funds to continue these important measurements. I hope you can join me in making a donation.


Figure 1. The Keeling Curve: climate change's most iconic image. The curve's steady year-by-year increase in CO2 due to burning of coal, oil, and natural gas has wriggles on top of it, due to the natural seasonal cycle in CO2--plants suck in CO2 during the Northern Hemisphere growing season, then release it during the winter.

CO2 Levels Hit 401 ppm
The latest data from the Keeling curve website shows that atmospheric carbon dioxide levels are surging upwards in their usual late winter push, as plants return CO2 to the atmosphere before the Northern Hemisphere spring growing season hits. CO2 levels reached 401 ppm (parts per million) last week on top of Mauna Loa, setting a new record. CO2 levels were at 280 ppm in 1870, increased less than 1 ppm per year in the 1960s, then accelerated to 2 ppm per year during the 2000s. Less than 1% of the increase since 1870 has been due to natural sources, such as volcanoes. The last time carbon dioxide levels reached 400 ppm—between 2.5 and 5 million years ago during the Pliocene Era—the Earth was 3.5 to 9° F warmer (2 to 5° C), and sea levels were 65 to 80 feet higher.

Senate holds all-nighter on climate change
A group of 31 U.S. Senators pulled an all-nighter last night on the floor of the U.S. Senate, taking turns from 9 pm Monday night until 9 am Tuesday morning to promote policy actions on climate change. Many of the Senators involved issued tweets using the hashtag #Up4Climate. The all-nighter was another indication that politicians are becoming increasingly bold about speaking up on climate change.

Latest Version of our WunderMap App Now Includes WunderPhotos
Weather Underground has released today a new version of our WunderMap app for iPhone and iPad. The main new feature that we'd like to highlight is the WunderPhotos layer--now users can view, share, and submit photos all from within the app. Here are a few of the features of the new version of the WunderMap app:

◦ Improved Weather Station display, and both station size and station spacing are now adjustable (Weather Stations Layer ⇒ Settings).
◦ New WunderPhotos layer! View, share, and submit beautiful weather photos.
◦ Fixed incorrect elevation for some Personal Weather Stations.
◦ Swipe-to-delete search history items.
◦ "Terrain/Satellite” and other map options made more prominent.
◦ Bug fixes (crashes, visual glitches, and usability enhancements).
◦ Optimized performance across all devices.


The latest version is available to download for iPhone and iPad at https://itunes.apple.com/app/wundermap/id364884105?mt=8.

Almost unbelievable. At this rate, all the spring flowers will have about four days to bloom before summer starts.

Better a few days ago. It showed it hitting Auckland with 979 mb almost directly. Now it's hitting a couple hundred klick a to the west and with pressures around 990 mb. Should only cause minor problems, but I've been wrong before.

Our cats are hangers-on... will not step a foot inside, but there is prodigious meowing in effect if food is not provided on the appropriate timely basis... lol...

Looking at the animation of that image I posted, it looks like the Central Bahamas may actually get some action before it's all over... I dunno if it'll hold together to bring some much-needed rain to the SE Bahamas and TCI, but that would be cool.

Windy conditions without outages would also be cool...

If you want to call .11" "much", then I guess we did. The HPC has called for 1.0"-1.50" for all three of the past storms and most I've gotten has been .16". Pretty depressing with summer coming on.
We've actually gotten fair amounts [usually more than .16, though I don't have exact totals to hand] with these passing fronts, certainly more than the 5 minute "downburst" type shower one associates with approaching fronts. I'm hoping we get another inch or 2 with whatever additional fronts we have in March... 'twill keep the dust and fires down [even if it does contribute to April pollen...]

Just had a 39 mph gust here and I thought the windows were going blow in. My anemometer has about a 5 second lag between a gust and when it's recorded. I sometime think I get higher gusts, but the anemometer doesn't pick them up fast enough. That's what you get with a $150 Chinese weather station I guess.
Hey... better than mine [stick the wet finger out the door and gestimate]...

Most areas in SE MI got 5-10" of snow, except for the Saginaw Valley and the Thumb. The most persistent banding set up farther north, which meant that the highest totals were further north than expected. I still got decent accumulations from the storm and had winds gust up to 40mph. Probably will break the record low of 5F tomorrow morning and wind chills will be below zero once again.

Nearest storm report: ROYAL OAK M 6.5 12 42.51N 83.15W
