It appears that the first daily CO2 measurement at Mauna Loa to break 400 ppm happened this week. This is just a daily measurement at the highest seasonal level of the year, not a whole year average.

Wow, I was just thinking to myself last night that all must be well in the climate change arena since there hasn't been a thread for quite a while. Oh well.
The trend line has been clear for a long, long time. What eludes the climate deniers is the possibility of any side effects. Severe weather is a 'crap shoot', easy to observe but hard to quantify. Sea level rise is one that is much harder to deny. Then there is the summer NorthWest Passage becoming a practical reality. Bob Wilson
Read the article in local, based on NY Times. Seems society is just on autopilot anyway. Cars, houses, buildings, factories, burning it all up. Too much to think about, so I don't. I can hardly believe a very smart and successful person in my family commented not long ago that 'they' have ways of injecting stuff into the atmosphere to counteract the CO2 problem. If so, seems 'they' would have done it by now.
Wasn't that the subject of a 'Dr Who' episode? When entertainment 'captured' news, a lot of folks never figured it out. Bob Wilson
Try to picture an ocean in which nothing can grow shells or bones. It'll be algae, mats of bacterial slime, and jellyfish. Yum. Difficulty in distinguishing fiction from fact seems to be a hallmark of a certain type of conservative.
I just read about the 400ppm here; Climate Milestone: Earth's CO2 Level Nears 400 ppm I'm thinking. . . . I'm hoping - that peak (cheap) oil will slow us down a bit.

There had not been a 'hundreds crossing' in the Mauna Loa CO2 record, so Scripps expanded their display to include hourly, daily, and weekly data. This brought media attention for sure. But with May being the month when the annual cycle goes negative (can be seen throughout the record), there will be at most a few other days above 400 ppm. In other words, annual average values will not break 400 ppm this year. 2016 would be likely for that, 2015 possible. All of May 2014 will be above 400. It is such a clear persistent pattern that such (confident) pronouncements are possible. However, people seeing the (seasonal) downward trend for the first time will be apt to misunderstand it I fear. If so, we'll probably read about it here and be back to patient correction mode. Known, on bad days, as whack a mole. In itself, 400ppm has not all that much meaning I suppose. the molecules do not know how many they are. They just absorb IR and vibrate. vibration is temperature in gases. Mojo's is the mole that still asks for whacking. Ignore that very decade air T is higher than the previous. Ignore the publications about increasing heat content in the oceans. If the second (falling) half of the current solar cycle does not bring cooler air, it will be necessary to ignore that as well. Really I thought that the Schmitt & Happer editorial in Wall Street Journal would get some attention here. They ignore all the things I've gone on about here recently. Like plant CO2 and glacial ice 'lag'. It is almost like they don't read PC and hang on my every word. Amazing.
The Wall Street Journal, editorial board, has no association with empiricism and the scientific method. So I wouldn't normally pay any attention to them and it didn't show up in my usually Google sources. Still, mediamatters pretty well took them apart: Empiricism and science has nothing to do with what the Wall Street Journal editorializes about. So I would rather read your posts here (or anywhere else) than waste time on those clowns. Bob Wilson
cooling? I duno one way or the other ... but just prior to your post, I thought I'd read just the opposite: NOAA: 2012 was warmest year ever for US, second most 'extreme' - U.S. News I'm sure all contenents vary ... and years vary from years. But then I look at black & white photos from 100 years ago. The glacier in Glacier National Park no longer exists on the Canadian side ... and the U.S. side has receeded miles & miles. Seems like that kind of century long bench mark flies in the face of "cooling". .
