The Very First Potentially Weekly Climate Update

CO₂ Level for January 19, 2019    412.51 ppm 
                        January 19, 2018    408.45 ppm

This probably represents an anomalous spike in that the average difference between 2018 and 2019 has been running about 2.5 ppm. However, the recent high, set on January 12, was 413.45 ppm. With approximately 3 more months until CO₂ reaches its annual peak it will probably reach close to 415 ppm.

Methane (CH₄) for November, 2018, was ~1900 ppb.

CH₄ levels are not tracked as closely as CO₂

Arctic sea ice extent for 1/19/19  13.600 million km² (6th lowest)
Antarctic sea ice extent for 1/19/19  3.670 million km² (2nd lowest)

While sea ice extent does not directly affect sea level changes it does impact ocean circulation, weather patterns, and accelerate the rate that glacial ice enters the oceans.

Recent articles of interest include:
How fast are the oceans warming? in Science, 1/11/19, which indicates that oceans are warming at a rate commensurate with current models. From the synopsis at ScienceDaily

Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or "hiatus" in global warming over the past 15 years were unfounded.

Diet and food production must radically change to save planet Again from ScienceDaily, based on an article in The Lancet

Transformation of the global food system is urgently needed as more than 3 billion people are malnourished (including people who are undernourished and overnourished), and food production is exceeding planetary boundaries -- driving climate change, biodiversity loss, pollution due to over-application of nitrogen and phosphorus fertilizers, and unsustainable changes in water and land use.

Of particular interest, although it isn't about the climate per se is Vaccinate public against science misinformation, researchers urge, an article on Cosmos which reviews Evidence-based strategies to combat scientific misinformation, published on 1/14/19 in Nature Climate Change. From Cosmos

Setting up an information-based “inoculation” program may be an effective way of combating the deliberately misleading messages of the fossil fuel industry and its representatives, researchers say.
In a detailed essay in the journal Nature Climate Change, Justin Farrell and Kathryn McConnell from Yale University, and Robert Brulle from Brown University, both in the US, explore strategies that scientists and advocacy bodies can employ to ensure evidence, rather than ideology and financial self-interest, once more informs environmental and climate policy.
Key to this approach is the brutal realisation that there is no value in climate scientists and advocates simply repeating that the evidence is overwhelming and irrefutable, even though it is. It is not sufficient to have faith in the ultimate triumph of the good guys.“It is not enough simply to communicate to the public over and again the scientific consensus on human-caused climate change,” the authors write.

While this is important for the issue of climate change the strategies proposed would also be useful when dealing with similar politically motivated occurrences of misinformation campaigns.
