Deep carbon refers to the carbon found beneath the subsurface of the Earth, where ninety percent of the Earth’s carbon resides. This vital part of the carbon cycle impacts the oceans, atmosphere and ultimately life on Earth. Despite this, there is still much unknown

"Elements" special issue

In a special, open-access issue of Elements, DCO collaborators investigate major, rapid shifts in the carbon cycle, including their impact on Earth and contribution to mass extinctions. .. “Anthropogenic contributions to the atmosphere far, far outweigh the natural carbon input into the atmosphere,” said Suarez. “When we went back into the geologic past, we saw that the amount of carbon being pumped into the atmosphere is at a similar magnitude – or more – than these catastrophic carbon perturbations.”

Rising sea levels pose threat to homes of 300m people – study

Land that is currently home to 300 million people will flood at least once a year by 2050 unless carbon emissions are cut significantly and coastal defences strengthened, says the study, published in Nature Communications. This is far above the previous estimate of 80 million.

Die G20-Staaten sind für 80 Prozent des weltweiten Treibhausgas-Ausstoßes verantwortlich. Ein neuer Klima-Report zeigt: Alle diese Länder sind weit davon entfernt, die Erderwärmung entscheidend zu begrenzen.

THE G20 TRANSITION TOWARDS A NET-ZERO EMISSIONS ECONOMY

The International Chamber of Commerce (ICC)—on behalf of 45 million institutional members—recognises that climate change is a growing emergency and wholly endorses the findings of the Intergovernmental Panel on Climate Change (IPCC) on the urgent need to keep the global temperature increase below 1.5°C.

The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(1) calculated from this in-situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2018, with CO2 at 407.8±0.1 ppm(2), CH4 at 1869±2 ppb(3) and N2O at 331.1±0.1 ppb. These values represent, respectively, 147%, 259% and 123% of pre-industrial (before 1750) levels. The increase in CO2 from 2017 to 2018 was very close to that observed from 2016 to 2017, and practically equal to the average yearly increase over the last decade. For CH4, the increase from 2017 to 2018 was higher than both that observed from 2016 to 2017 and the average over the last decade. For N2O, the increase from 2017 to 2018 was also higher than that observed from 2016 to 2017 and the average growth rate over the past 10 years. The National Oceanic and Atmospheric Administration (NOAA) Annual Greenhouse Gas Index (AGGI) [9] shows that from 1990 to 2018 radiative forcing by long-lived greenhouse gases (LLGHGs) increased by 43%, with CO2 accounting for about 80% of this increase.

The Production Gap Report – produced by leading research organizations and the UN – is the first assessment of the gap between the targets of the Paris Agreement and countries’ planned production of coal, oil and gas.  It provides a new metric for assessing the world’s current pace of fossil fuel extraction and details the steps countries can take to align fossil fuel supply with Paris Agreement goals. This new report finds that the world is on track to produce far more coal, oil and gas than is consistent with limiting warming to 1.5°C or 2°C, creating a “production gap” that makes climate goals much harder to reach.  It is a report that calls for a sharpened, and long overdue, focus on fossil fuels.

Governments are planning to produce about 50% more fossil fuels by 2030 than would be consistent with a 2°C pathway and 120% more than would be consistent with a 1.5°C pathway. This global production gap is even larger than the already- significant global emissions gap, due to minimal policy attention on curbing fossil fuel production.

The science and the global challenge are clear: unless NDC ambitions are increased immediately and supported by  action,  exceeding  the  1.5°C  goal  can  no  longer  be  avoided and the well below 2°C goal will slip increasingly out  of  reach.  The  Emissions  Gap  Report  (United  Nations  Environment Programme [UNEP] 2018) showed that nations must triple the level of ambition in their current NDCs to get on track towards limiting global warming to below 2°C, while a fivefold increase is needed to align global climate action and emissions with limiting warming to 1.5°C by the end of this century. For this to be realistic new and enhanced NDCs must be agreed by 2020 and the implementation of existing actions must be accelerated.

The climate crisis upon us now requires that countries and non-Party stakeholders, everyone, step up their climate action. We are all part of the solution. We must unite behind the science, working together in the spirt and practice of inclusive multilateralism, with an intergovernmental process led by Parties involving all non-party stakeholders in the quest for solutions to climate change.

The Yearbook reflects work of the High-Level Champions together with the Marrakech Partnership stakeholders in 2019 to create Climate Action Pathways that set out clear visions for sectors to reach the Paris goal. All thematic areas, guided by science, are working together towards the 1.5-degree goal and creation of a climate-resilient world. The Yearbook contains synergies, gaps and opportunities that have been identified, which in turn can be shared in the newly evolved Global Climate Action Portal.

The Yearbook is a valuable assessment of where we stand with respect to non-Party action and points to areas where success might be gained. Thus, it is a valuable resource for policymakers.
