Limiting global warming to 1.5C requires strictly limiting the total amount of carbon emissions between now and the end of the century. However, there is more than one way to calculate this allowable amount of additional emissions, known as the “carbon budget”. In this article, Carbon Brief assesses nine new carbon budget estimates released recently.
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.
“There was no name for what we were proposing. It was bold, imaginative, and beyond what most folks thought of as environmentalism. It wasn’t environmentalism, it was much more than that.” A blog by Naresh Giangrande Co-founder of Totnes, the world’s first Transition-Town, as he signs off after a ten-year adventure in global social change.
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.
Most courses on energy deal with it in an instrumentalist manner, as if it were another substance that humans can tap and use for their benefit. Platform for Sustainability and Equity and Ecologise are pleased to announce an online course that places energy at the centre of all transformations— abiotic, biotic and in human society.
We know that economies need to grow, or they collapse. The wage disparity that high-wage countries have been experiencing in recent years is evidence that the world economy is already reaching energy limits. There are no longer enough jobs that pay well to go around. Any drop in energy supply will likely worsen the situation.
Some of the most celebrated scientific ideas and books of the 20th century may not be useful for us in this century, while lesser-known works of the past acquire new relevance. Here, then, is a selection of such works, along with an invitation for readers to critique and contribute their own suggestions to this list.
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.
Ecologise has consistently driven home that humanity needs to prepare for unprecedented environmental, economic and socio-political upheaval and uncertainty in the 21st century. In this new series, we showcase free short-duration online courses that focus on these various emerging crises and possible responses. Created by the world’s leading universities, they offer a good starting point to explore these complex challenges.
Amory Lovins, Chief Scientist of the Rocky Mountain Institute, is one of the world’s leading energy experts and a key figure behind China’s ongoing transition to renewable energy. His appointment as a strategic advisor to NITI Aayog suggests that India’s top development policy agency maybe finally be rethinking the country’s present fossil fuel-based energy path.
Nityanand Jayaraman writes in Dianuke.org: We do not need four more nuclear plants in Koodankulam. The need of the hour is to shut down the existing two risky units and to prosecute the ministers, technocrats and bureaucrats who led the nation up the garden path and wasted more than Rs. 35,000 crores of our money.
From Newsclick: Prof. Tejal Kanitkar, who heads the Centre for Climate Change and Sustainability Studies at TISS, says that while the government’s National Energy Policy claims it will provide 24×7 electricity to the entire nation by 2022, this lies in contradiction with the mode through which they plan ensure its distribution; that is, the market.
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.
From The Wire: An Indian Oil Terminal, which can store up to 15,400 metric tons of cooking gas, is scheduled to be built in Vypeen, Kochi, which is among the world’s most densely populated islands. Will Kerala’s Communist Patrty-led government allow this high risk project to come up, defying all common sense and public opinion?
“This may take a while, but we’re going to win.” This is true about most political fights, but not for climate change. If we don’t win very quickly on climate change, then we will never win. That’s the core truth. It’s what makes climate change different from every other problem our political systems have faced.
Gail Tverberg writes: World leaders manipulate the world economy like a giant video game. The object is to keep it growing, but what do they do when the economy hits limits? They could take their foot off the throttle operated by low interest-rates and more debt. Or they could “take the wings off” the economy.
From The Guardian: Of all the most polluting nations –United States, China, Russia, Japan and the EU bloc– only India’s carbon emissions are rising: they rose almost 5% in 2016. India’s population and emissions are rising fast, and its ability to tackle poverty without massive fossil fuel use will decide the fate of the planet.
Delhi’s killer smog has been blamed on many things, but rarely on highly polluting industrial fuels like petcoke. India is the world’s biggest importer of this dirtiest of fuels, banned in most countries. Last month, the Supreme Court banned it in the NCR; but given the big players involved, who will ensure the ban’s implemented?
In a significant article in The Citizen, Dr A.Gopalakrishnan, the former Chairman of the India’s Atomic Energy Regulatory Board, writes: An overall evaluation of the status of the Indian civilian nuclear power sector, and the government’s uncertain future plans, do cause a great deal of concern for the welfare of the country and the safety
