It’s 20 years since we started blogging on climate here on RealClimate (December 10, 2004). There is one graph that perhaps tells the story of what has happened since 2004, and it’s the Keeling curve shown in the figure below. Another thing I didn’t anticipate in 2004 was efforts such as the World Weather Attribution (WWA).

2004 ) which is a better representation of the mid-troposphere than the classic TMT diagnostic through an adjustment using the lower stratosphere record (i.e. ). 55-58, 2004. After my annual update , I was pointed to some MSU-related diagnostics for many of the CMIP6 models (24 of them at least) from Po-Chedley et al. Johanson, S.G.

Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming. In North America, the land carbon sink between 2004 and 2013 offset roughly 39% of fossil fuel emissions , but varied substantially year to year.

Instruments installed on the International Space Station are refining weather forecasts by measuring water vapor in the atmosphere and water held in clouds. Incorporating satellite data, the program estimates water that plants “breathe” into the atmosphere and water that evaporates from farm fields. Hossain joined the team in 2008.

The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming. In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change. 353-366, 2004. 2016 ), could increase again in concentration. Zhang et al.

Well, back in 1993 (before the more comprehensive critiques had been published), Hoyt and Schatten put together a long-term estimate of solar activity that relied on the SCL, based on the idea from FCL91 and scaled to a finding about cycling and non-cycling stars that turned out to be wrong too (Wright, 2004). 1273-1278, 2004.

About five years later, analysis of an extended simulation of yet another climate model–the coupled ocean-atmosphere model run by the Hadley Centre within the UK Meteorological Office, yielded evidence for a similar oscillation, albeit with a longer (roughly 100 year) period, and a more global signature (Knight et al., Ammann, and P.
