Annual Greenhouse Gas Index (AGGI), 1750-2019. For 2019, the AGGI was a record high 1.45, representing an increase in total direct radiative forcing of 45% since 1990. The increase in radiative forcing from CO2 alone since 1990 was 60.6%. Pre-1978 changes in the CO2-equivalent abundance and AGGI are based on the ongoing measurements of all greenhouse gases reported here, measurements of CO2 going back to the 1950s from C.D. Keeling (Keeling et al., 1958), and atmospheric changes derived from air trapped in ice and snow above glaciers (Machida et al., 1995, Battle et al., 1996, Etheridge, et al., 1996; Butler, et al., 1999). Equivalent CO2 atmospheric amounts (in ppm) are derived with the relationship between CO2 concentrations and radiative forcing from all long-lived greenhouse gases.

NOAA Annual Greenhouse Gas Index reached another record high in 2019 – Total direct radiative forcing has increased 45 percent since 1990

14 May 2020 (NOAA) – […] The NOAA monitoring program provides high-precision measurements of the global abundance and distribution of long-lived greenhouse gases that are used to calculate changes in radiative climate forcing. Air samples are collected through the NOAA/GML global air sampling network, including a cooperative program for the carbon gases which provides samples […]

With the public distracted, U.S. Interior Department moves full speed ahead on oil and gas leases

By Maria Caffrey 20 March 2020 (UCS) – We are currently in a state of national emergency thanks in no small part to the Trump administration’s muzzling of public health experts and slow response to the COVID-19 pandemic. As we all do our part to limit the extent of this outbreak, the Department of the Interior (DOI) instead appears to be […]

Fanning the Flames: How executives continue to be rewarded to produce more oil and gas at odds with the energy transition

13 March 2020 (Carbon Tracker) – Company pay practice doesn’t yet live up to climate ambition, with the gap between stated ambition and demonstrable action widening. The energy transition is a challenge to the traditional business model of the oil and gas industry, and companies are increasingly exposed to transition-related financial risks. Over the past […]

University of Rochester researchers in Greenland drill for ice cores, which contain air bubbles with small quantities of ancient air trapped inside. By measuring the carbon-14 isotope in air from more than 200 years ago, the researchers found that scientists have been vastly overestimating the amount of fossil methane emitted by natural sources, and have therefore been underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.

Methane emitted via human fossil fuel use “vastly underestimated”

By Lindsey Valich 19 February 2020 (University of Rochester) – Methane is a powerful greenhouse gas and large contributor to global warming. Methane emissions to the atmosphere have increased by approximately 150 percent over the past three centuries, but it has been difficult for researchers to determine exactly where these emissions originate; heat-trapping gases like […]

The “blue acceleration”: Study shows humans’ surging incursions into the sea

By Grace Dungey 13 February 2020 (Mongabay) – Humanity has depended on the ocean for millennia. Today, however, the rush to the sea is occurring with unprecedented diversity and intensity, propelled by population growth and demand for diminishing terrestrial resources. A study published in January in the new journal One Earth analyzed 50 years of data on 18 kinds […]

Obscure investment fund uses UK aid money to finance fossil fuel projects – “A farcical situation where the Government, on one hand, spends aid money to mitigate climate change, and on the other hand finances fossil fuels all over the world”

6 February 2020 (Global Witness) – We are at the beginning of a year of climate spin by the British Government. This year, the UK will host the 26th UN Climate Change Conference (COP26) in Glasgow. While the Government claims to be a ‘climate leader’, we reveal how a little-known investment group funded by the […]

“Fast and dramatic” permafrost thaw will double previous estimates of potential carbon emissions – “Forests can become lakes in the course of a month”

By Natacha Larnaud 4 February 2020 (CBS News) – Rapidly thawing permafrost in the Arctic has scientists worried. According to a new study published Monday in the journal Nature Geoscience, the ice that holds the soil together is melting, causing hillsides to collapse and massive sinkholes to open up as a result. And that dramatic disruption to […]

Preliminary U.S. carbon emissions estimates for 2019 – Coming up short on climate targets

By Trevor Houser and Hannah Pitt 7 January 2020 (Rhodium Group) – After a sharp uptick in 2018, we estimate that US greenhouse gas (GHG) emissions fell by 2.1% last year based on preliminary energy and economic data. This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by […]

EIA projects nearly 50 percent increase in world energy usage by 2050, led by growth in Asia – Carbon dioxide emissions to grow from all three fossil fuel sources

3 January 2020 (EIA) – In its newly released International Energy Outlook 2019 (IEO2019) Reference case, the U.S. Energy Information Administration (EIA) projects that world energy consumption will grow by nearly 50 percent between 2018 and 2050. Most of this growth comes from countries that are not in the Organization for Economic Cooperation and Development (OECD), and […]

Poverty grew in one-third of U.S. counties despite strong national economy

By Tim Henderson 19 December 2019 (Pew) – Despite an economic recovery that lifted people out of poverty in most areas of the country, poverty increased in at least one county in every state between 2016 and 2018. The poverty rate grew in 30% of counties between 2016 and 2018, according to a Stateline analysis of U.S. Census […]
