Global Atmospheric Carbon Dioxide

Global atmospheric carbon dioxide concentrations from Oct. 1 through Nov. 11, as recorded by NASA's Orbiting Carbon Observatory-2. Carbon dioxide concentrations are highest above northern Australia, southern Africa and eastern Brazil. Preliminary analysis of the African data shows the high levels there are largely driven by the burning of savannas and forests. Elevated carbon dioxide can also be seen above industrialized Northern Hemisphere regions in China, Europe and North America.

#AGU14 NASA’s Orbiting Carbon Observatory shows surprising CO2 emissions in Southern Hemisphere

The first global maps of atmospheric carbon dioxide from NASA’s new Orbiting Carbon Observatory-2 mission demonstrate its performance and promise, showing elevated carbon dioxide concentrations across the Southern Hemisphere from springtime biomass burning. At a media briefing today at the American Geophysical Union meeting in San Francisco, scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California;…

#AGU14 Stanford researchers use a girl scout troop as guinea pigs for climate ‘behavior change’

From the Stanford University press office: AGU talk: Scaling climate change communication for behavior change In a previous randomized controlled trial, Stanford University researchers developed two curricula for Girl Scouts to use energy more efficiently: one on energy use at home, and the other in transportation and food. Both courses were effective for girls in…

New Study: Two Thousand Years of Northern European Summer Temperatures Show a Downward Trend

In a paper published in the Journal of Quaternary Science, Esper et al. (2014) write that tree-ring chronologies of maximum latewood density (MXD) “are most suitable to reconstruct annually resolved summer temperature variations of the late Holocene.” And working with what they call “the world’s two longest MXD-based climate reconstructions” – those of Melvin et…

Early Results from NASA’s Orbiting Carbon Observatory-2 Mission to be presented at #AGU14 via Live Stream

Time: Thursday, Dec. 18, 9 a.m. PST In 2014, NASA launched four new missions to study our home planet, including the Orbiting Carbon Observatory-2 in July – NASA’s first mission dedicated to studying atmospheric carbon dioxide. This press conference will present early results from the OCO-2 mission. Fossil fuel combustion, deforestation and other human activities…

Arctic Albedo Variations

Guest Post by Willis Eschenbach Anthony has just posted the results from a “Press Session” at the AGU conference. In it the authors make two claims of interest. The first is that there has been a five percent decrease in the summer Arctic albedo since the year 2000: A decline in the region’s albedo –…

DECC Forced To Release Data Showing Impact Of Climate Policies On Energy Prices

By Paul Homewood http://www.telegraph.co.uk/news/earth/energy/11292367/Green-policies-to-add-up-to-40pc-to-cost-of-household-electricity.html Earlier I posted on the news that Department of Energy & Climate Change (DECC) tried to cover up official data showing how electricity prices are expected to skyrocket, as a direct result of climate policies. (See above Telegraph article). I’ve now had a chance to dissect this data. They base their…

Hump Day Hilarity – model the bouncing ball

Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit like watching a ball bouncing down a rocky hillside. You can predict some aspects of it behaviour but not others. You can predict it will…

The 2-Deg Global-Warming Limit

Guest Post by Bob Tisdale Politicians from around the globe gather annually in the UNFCCC meetings so they can propose and fail to come to worthwhile agreements on how to limit global warming and its impacts.  Year in, year out, same thing.  For the results of the most recent failed gathering, see the WattsUpWithThat post…

Some first impressions from #AGU14

Mann, Cook, Nuccitelli get put off-site for their presentations I spent Monday looking around at the sights on the opening day of AGU 2014. Before I get to that I want to give some thanks to some people. First of all I want to give thanks to my readers for their gracious assistance in getting…

New Paper Tackles Ethical Disputes Of Climate Policy

Bishop of Chester: ‘Climate policies that lack in-depth debate won’t have democratic consent’ London, 16 December: A new paper by Dr Peter Lee and published today by the Global Warming Policy Foundation explores many of the ethical disputes that characterise climate science and policy in the twenty-first century. “Science has spoken. There is no ambiguity…

Guest Post by Bob Tisdale This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through November 2014 and HADCRUT4 and NCDC through October 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through November 2014. The three surface data suppliers…

The Nonsensical “Just What AGW predicts” and Other Claims By Alarmists about “Record-High” Global Sea Surface Temperatures in 2014

Guest Post by Bob Tisdale Many of the visitors here at ClimateObservations and at WattsUpWithThat also spend time arguing with climate alarmists at other websites around the blogosphere. With global sea surface temperatures at record high levels in 2014, the true-blue believers in the hypothesis of human-induced global warming are out in force. This post…

From Stanford News Service: MEDIA ADVISORY. Stanford at AGU Fall Meeting. Global warming’s influence on extreme weather Understanding the cause-and-effect relationship between global warming and record-breaking weather requires asking precisely the right questions. Extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are becoming more common in many…
