IPCC: Renewables, Not Nuclear Power, Can Solve Climate Crisis
The authoritative Intergovernmental Panel on Climate Change (IPCC) has left zero doubt that we humans are wrecking our climate.
It also effectively says the problem can be solved, and that renewable energy is the way to do it, and that nuclear power is not. The United Nations’ IPCC is the world’s most respected authority on climate.
This IPCC report was four years in the making. It embraces several hundred climate scientists and more than a thousand computerized scenarios of what might be happening to global weather patterns.
The panel’s work has definitively discredited the corporate contention that human-made carbon emissions are not affecting climate change. To avoid total catastrophe, says the IPCC, we must reduce the industrial spew of global warming gasses by 40-70 percent of 2010 levels.
Though the warning is dire, the report offers three pieces of good news.
First, we have about 15 years to slash these emissions.
Second, renewable technologies are available to do the job.
And third, the cost is manageable.
Though 2030 might seem a tight deadline for a definitive transition to Solartopia, green power technologies have become far simpler and quicker to install than their competitors, especially atomic reactors. They are also far cheaper, and we have the capital to do it.
The fossil fuel industry has long scorned the idea that its emissions are disrupting our Earth’s weather. The oil companies and atomic reactor backers have dismissed the ability of renewables to provide humankind’s energy needs.
But the IPCC confirms that green technologies, including efficiency and conservation, can in fact handle the job—at a manageable price.
“It doesn’t cost the world to save the planet,” says Professor Ottmar Edenhofer, an economist who led the IPCC team.
The IPCC report cites nuclear power as a possible means of lowering industrial carbon emissions. But it also underscores considerable barriers involving finance and public opposition. Joined with widespread concerns about ecological impacts, length of implementation, production uncertainties and unsolved waste issues, the report’s positive emphasis on renewables virtually guarantees nuclear’s irrelevance.
Some climate scientists have recently advocated atomic energy as a solution to global warming. But their most prominent spokesman, Dr. James Hansen, also expresses serious doubts about the current generation of reactors, including Fukushima, which he calls “that old technology.”
Instead Hansen advocates a new generation of reactors.
But the designs are untested, with implementation schedules stretching out for decades. Financing is a major obstacle as is waste disposal and widespread public opposition, now certain to escalate with the IPCC’s confirmation that renewables can provide the power so much cheaper and faster.
With its 15-year deadline for massive carbon reductions, the IPCC has effectively timed out any chance a new generation of reactors could help.
And with its clear endorsement of green power as a tangible, doable, affordable solution for the climate crisis, the pro-nuke case has clearly suffered a multiple meltdown.
With green power, says IPCC co-chair Jim Skea, a British professor, a renewable solution is at hand. “It’s actually affordable to do it and people are not going to have to sacrifice their aspirations about improved standards of living.”

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
