We’re not going to get a decarbonized energy system by 2050. We’re going to fail the climate targets, probably by a large margin, and I suspect that a warming of about 3 degrees centigrade is going to be almost inevitable. It’s perfectly possible that self-amplifying feedback mechanisms under way will amplify this change even more.
In this informative book, the author, Dr. Ashok Kundapur, who has had the privilege of contributing scholarly articles to Enclyclopedia of Life Support System (EOLSS) of UNESCO and Wikia of Solar Cooker International, has distilled his experience of 35 years, to cover over 260 designs of solar cookers, in full color, designed around the World.
Richard Heinberg writes: Many problems are converging at once because society is a complex system, and the challenges we have been discussing are aspects of a systemic crisis. A useful way to frame an integrated understanding of the 21st century survival challenge is this: we humans have overshot Earth’s long-term carrying capacity for our species.
From The Guardian: A series of fast-moving global megatrends, spurred by trillion-dollar investments, indicates that humanity might be able to avert the worst impacts of global warming. From those already at full steam, including renewable energy, to those just emerging, such as plant-based alternatives to meat, global trends show that greenhouse-gas emissions can be halted.
With the national energy policy about to be finalised, a recent lecture by Dr. Arvind Subramanian, India’s chief economic advisor, revealed the government’s thinking on the question of coal vis-a-vis renewable energy. This rejoinder by an energy expert flags crucial issues and suggests alternatives that are vastly more healthier for the country and the planet.
A coalition of investigative journalists, privacy activists and alternative economy enthusiasts including Nafeez Ahmed, John Pilger and Barkha Dutt, have announced Presscoin/Insurge, a fascinating new hybrid platform that seeks to meld cutting-edge journalism with activism and alternative currencies. “Dedicated to people and the planet, it represents a fundamental break with the old paradigm,” Nafeez says.
Mankind is facing the existential threat of runaway consumption of limited resources by a rapidly growing population, says a new, dire “warning to humanity” written by 15,000 scientists from 184 countries.The message updates an original warning sent 25 years ago. The experts say the picture now is far, far worse than it was in 1992.
Narsanna Koppula, a pioneer of permaculture in India, founded Aranya Agricultural Alternatives, with an aim to provide alternate solutions to the present chemical agricultural practices. Later this month, Aranya, which has impacted thousands of farmers in Telangana and Andhra, is playing host to the International Permaculture Convergence, the biggest event on the permaculture calendar globally.
Moin Qazi writes: The Indian film celebrity Aamir Khan is shepherding a very revolutionary campaign–making Maharashtra drought-free in five years. Khan’s Paani Foundation is galvanising the rural population to go back to fundamental lessons of water management taught by their ancestors. Many Maharashtra villages are seeing water in their parched lands after consecutive dry years.
As India like the rest of the world shifts from fossil fuels to renewables, India should also launch a new initiative for this dramatic transition. One of the guiding principles for energy transition should be India’s civilizational value of “simple living and high thinking” and not to maximize gross national product as other countries do.
Barry Saxifrage writes: What determines our climate fate is how much climate-polluting fossil fuels we burn. Renewables are great, but only if they actually replace oil, gas, or coal. Sadly, rising renewables haven’t stopped our fossil fuel burn. Instead, we keep expanding both renewables and fossil fuels at the same time, in a new business-as-usual.
Billions in Change, the brainchild of Indian-American entrepreneur Manoj Bhargava, shows how simple but life-changing inventions provide clean water, electricity, and improve rural lives. The innovations include a RainMaker device that can turn dirty water clean, a low-cost, portable solar-based power generator and a ‘cost-free fertilizer’ that is made by gathering whatever is laying around.
Gail Tverberg writes: The Politically Correct (PC) worldview has been called the “religion of success”. In this post, I explain why many popular (or politically correct) understandings are just plain wrong. I cover many controversial topics, including environmentalism, peer-reviewed literature, climate change models, and yes, religion. I expect that the analysis will surprise almost everyone.
A recent lecture by Dr. Arvind Subramanian, the Indian government’s chief economic advisor, offers clues on its thinking on coal vis-a-vis renewable energy, crucial for meeting its stated climate goals. In this stinging rejoinder to the lecture, energy expert Prof. Mahesh Bhave shows conclusively why mainstream economists like Dr. Subramnian simply do not ‘get’ energy.
From Down to Earth: These locally led green start-ups across Africa are not just promising but also innovative in their approach. From providing clean energy to ensuring safe sanitation and reducing carbon emission to improving public health, the activities of these start-ups in Africa are guided by a common objective: sustainable management of natural resources.
From Solutions Journal: The stunning manner in which the Zapatistas presented themselves to the Mexican government, as well as the world, saw them descend upon several towns, cities, prisons, and wealthy landowners. During the revolt, guerillas liberated political prisoners, stormed military barracks, occupied government offices, set fire to trumped-up files that unfairly criminalized Indigenous people.
Richard Heinberg writes: Over the past century-and-a-half, fossil fuels enabled the rapid growth of resource extraction, manufacturing, and consumption; and these in turn led to population increase, pollution, and loss of natural habitat and hence biodiversity. Our core ecological problem is not climate change. It is overshoot, of which global warming is only a symptom.
Frontline reports: Across the country, large tracts of land are being earmarked for exclusive solar power parks. The rocky terrain of Madhya Pradesh’s Neemuch district has emerged as the largest solar power-generating hub in India, but the nomadic communities that have lived there for generations find themselves dispossessed of land and reduced to abject poverty.
Even when we question the personal impacts of modern technology, how many of us consider how our dependence on technology might be harming us? Or question the belief that technological advances will save us from our most pressing environmental and societal challenges? Richard Heinberg tackles this thorny issue in this brilliant essay and animation feature.
CarbonBrief reports: On the roof of a waste incinerator outside Zurich, the Swiss firm Climeworks has built the world’s first commercial plant to suck CO2 directly from the air. They claim that their direct air capture process –a technology often considered too expensive– aims to capture 1% of global CO2 emissions each year by 2025.
