    Agroforestry is essentially a forest-mimicking agriculture that involves growing trees, shrubs and vegetables in tight assemblages. It is an ancient technology created by indigenous peoples and popularized in recent decades by newer landowners. Although it’s difficult to pin down how much of the world’s agricultural land contains tree cover, figures range from 100 million hectares to as much as 1 billion hectares, which lock up an estimated .75 gigatons of carbon per year. By comparison, there were 32.5 gigatons of global carbon emissions in 2017.

    In terms of cost, agroforestry is likely much cheaper than Carbon Engineering’s invention, not to mention that it will likely take much more carbon-emitting energy to operate their machines on the global scale that they envision. Project Drawdown, a carbon solution tracking initiative, estimates a cost of $26.8 billion to implement agroforestry on an additional 19 million hectares globally — sequestering 9.3 billion gigatons of carbon and providing an estimated profit of $710 billion for farmers and investors by 2050. Institutions with “climate-smart” agriculture support programs like the World Bank and the UN Food and Agricultural Organization could supply some of the needed funding and channel it through the training and extension programs of nonprofits like the World Agroforestry Centre. Private investors seeking carbon credits can likely provide significant capital as well.

    The German auto market is nearly back to normal, down just 5% in July, but the local plugin electric vehicle market is far beyond that — it’s red hot right now. Plugin vehicles (fully electric vehicles as well as plugin hybrids) scored an amazing 36,000 registrations in July, which not only a new record, but is 85% above the last record, made last March.

    world has successively blown past various emissions reductions targets over the past generation, climate and energy modelers have had to rely more and more on 'negative emissions' to achieve their goals (in models). While negative emissions are not a substitute for near-term mitigation, they offer some flexibility if emissions overshoot targets. For a time, the main negative-emissions technology used in climate models was bioenergy with carbon capture and storage, or BECCS. But real-world deployment of BECCS would require vast amounts of land — an area up to to five times the size of India — which would compete with other land uses and threaten ecosystems. Natural carbon sequestration, including large-scale reforestation, is a more promising option, but it would only replace the carbon released when those forests were first cut down — it won't be enough to substantially reduce future warming.

    Halliburton, the world’s biggest fracking provider, expects the worst-ever slump in oil exploration to end soon. Almost three-fourths of the nation’s active oil rigs have been sidelined this year. “We do see some recovery in the back half” of this year, Halliburton Chief Executive Officer Jeff Miller said during a recent interview. “Fracking activity reached a bottom in the second quarter. I think we’ll see drilling activity reach a bottom in the third quarter and then some modest recovery.”

    In our collective, we have mapped four denials that severely restrict the capacity of those of us socialized within modernity-coloniality to sense, relate and imagine otherwise:

    the denial of systemic, historical and ongoing violence and of complicity in harm (the fact that our comforts, securities and enjoyments are subsidized by expropriation and exploitation somewhere else);

    the denial of the limits of the planet and of the unsustainability of modernity-coloniality (the fact that the finite earth-metabolism cannot sustain exponential growth, consumption, extraction, exploitation and expropriation indefinitely);

    the denial of entanglement (our insistence in seeing ourselves as separate from each other and the land, rather than “entangled” within a living wider metabolism that is bio-intelligent); and,

    the denial of the magnitude and the complexity of the problems we need to face together (the tendency to look for simplistic solutions that make us feel and look good and that may address symptoms, but not the root causes of our collective complex predicament).
    One final denial is denial of the ways that these four denials are all interconnected. It is common for critical educational initiatives to address one or maybe two of these denials at a time, but we have thus far not encountered any initiatives, especially in the context of low-intensity struggles, that seriously engage with all four

    During the last glacial period from 120,000 to 11,000 years ago, there were over 20 abrupt periods of rapid warming (D-O Oscillations) exceeding 1 degree C per decade warming recorded in the North Greenland Ice Project (NGRIP) cores. I continue to chat about the latest science comparing both the rates of change of warming as well as the spatial distribution of the warming between these D-O events and present day (contemporary) Arctic warming. In the paleoclimate D-O warming events, large Greenland ice sheet melting was preceded by extensive loss of Arctic sea ice; a pattern that we are expecting to experience again.

    Climate science and nuclear weapons testing have a long and surprisingly intimate relationship. The global networks that monitored the Fukushima radiation plume and forecasted its movement are the direct descendants of systems and computer models developed to trace fallout from weapons tests. Tracing radioactive carbon as it cycles through the atmosphere, the oceans, and the biosphere has been crucial to understanding anthropogenic climate change. The earliest global climate models relied on numerical methods very similar to those developed by nuclear weapons designers for solving the fluid dynamics equations needed to analyze shock waves produced in nuclear explosions. The climatic consequences of nuclear war also represent a major historical intersection between climate science and nuclear affairs. Without the work done by nuclear weapons designers and testers, scientists would know much less than they now do about the atmosphere. In particular, this research has contributed enormously to knowledge about both carbon dioxide, which raises Earth’s temperature, and aerosols, which lower it. Without climate models, scientists and political leaders would not have understood the full extent of nuclear weapons’ power to annihilate not only human beings, but other species as well. In the post-Cold War era, US national laboratories built to create the most fearsome arsenal in history are now using their powerful supercomputers, their expertise in modeling, and their skills in managing very large data sets to address the threat of catastrophic climate change.

    A jeden z prvnich general circulation models z pocatku sedesatych let

    One of the first general circulation models was developed at Lawrence Livermore National Laboratory by Cecil “Chuck” Leith in the early 1960s. Unlike the NOAA model mentioned above, Leith’s model only simulated the atmosphere. What make Leith’s work so remarkable was that he was the first to produce a computer animation based on the model output. Watch the video below to see how these wobbling yet compelling animations looked.

    After 48 Years, Democrats Endorse Nuclear Energy In Platform
    https://www.forbes.com/...020/08/23/after-48-years-democrats-endorse-nuclear-energy-in-platform/amp/

    It took five decades, but the Democratic Party has finally changed its stance on nuclear energy. In its recently released party platform, the Democrats say they favor a “technology-neutral” approach that includes “all zero-carbon technologies, including hydroelectric power, geothermal, existing and advanced nuclear, and carbon capture and storage.”

    The European Union can significantly increase its climate protection target for 2030. According to a new study by Agora Energiewende, it is technically and economically possible for EU Member States to achieve a 55% reduction in greenhouse gas emissions by 2030 compared to 1990. Currently, the EU aims to achieve a 40% reduction by 2030. Increased climate protection efforts are necessary to limit the rise in average global temperatures to well below 2 degrees Celsius and thus fulfill the goal set forth by the 2015 Paris Agreement.

    For emissions from industry and the energy sector, which are regulated by the EU emissions trading scheme, the study proposes a greenhouse gas reduction of 59 to 63% compared to 2005 – a tightening of 16 to 20 percentage points. Emissions in the other sectors – particularly transport, buildings and agriculture – could be reduced by 45 to 49 percent compared to 2005 – that is, 15 to 19 percentage points more than previously envisioned.

    The study was prepared against the backdrop of current debate surrounding a higher climate protection target for 2030. A new target is to be adopted under the German EU Council Presidency by the end of the year, and subsequently presented to the international community at the COP26 climate conference in Glasgow in 2021. In the run up to the conference, the European Commission also intends to submit proposals for modifying the EU’s policy architecture for climate protection.
