“the military’s own bases are very vulnerable to the effects of climate change because of rising seas and forest fires, storms, and floods.”
“The idea is simple: Someone else can withdraw what you deposit. More specifically, an emitter of a certain quantity of carbon dioxide can pay to compensate for it, leading to no net increase of heat-trapping gases. That compensation can come from planting trees that take in carbon dioxide as they grow, installing renewable energy that replaces fossil fuels, or destroying potent heat-trapping gases like nitrous oxide before they reach the atmosphere.
With an offset, you have an accounting mechanism that bridges greenhouse gas emitters with climate protectors. And offsets are now fueling a multibillion-dollar global market.
But to make a useful carbon offset, you have to consider four key factors.”
“Energy analysts, however, caution that Sanders’s 2030 plan would require a federal infrastructure investment not seen since the construction of the interstate highway system. To get close to Sanders’ 100 percent clean energy goal by 2030, researchers estimate the U.S. would need to add about 800 GW of wind and solar resources — about 25 times the amount the federal government expects to be built this year — along with ample amounts of battery storage and transmission. The Sanders camp forecasts that would cost about $2 trillion.
“Our best year for solar and wind — we’d have to multiply that by three and then sustain it for the next decade,” said Sonia Aggarwal, vice president at the analysis firm Energy Innovation, which advises world governments on their climate targets.
While turning the power grid over to 100 percent renewables presents significant technical difficulties, the clean energy deployment is “not out of the question,” Aggarwal said. However, Sanders’ plan to shut down nuclear power plants will make it “much more difficult.” The nation’s 60 nuclear plants generated more than half of U.S. carbon-free energy last year, but the Sanders campaign says it will phase them out by denying extensions of their operating licenses when they expire.
Many of those nuclear plants have licenses that expire after 2030, but Sanders expects the cheaper solar and wind power to drive most them into retirement. The stability those reactors provide to the power grid would be hard to replace with the variable output of the renewables, said Leah Stokes, assistant professor of political science at the University of California Santa Barbara.”
“Over the years, the terms “free market” and “limited government,” like so many conservative principles, have devolved into little more than rhetorical tics, bits of sloganeering that bear no resemblance to actual conservative governance.
What conservatives seem to have decided is that regulations, restrictions, or limitations — anything that might upset or inconvenience the corporations generating greenhouse gases — are the bad kind of big government and a bad way of picking winners and losers. Government subsidies, tax credits, and grants — anything that might benefit big corporations — is the good kind of big government and a good way of picking winners and losers.”
“There are plenty of models that show we will need carbon capture (both industrial and natural) to supplement other efforts to reduce emissions. We probably can’t hit our mid-century targets without it.
But there is no model in the world showing emissions falling fast enough with nothing but carbon capture, with fossil fuels continuing their current headlong expansion.
The fossil fuels that remain behind after deep decarbonization, the ones that still need their emissions captured and buried, will be a small vestige of the current fossil fuel regime. That is what every credible model shows. That is the cold, hard truth at the heart of the climate dilemma: There is no avoiding the imperative to reduce fossil fuel combustion and the social and economic disruptions that come with it.
Current Republican efforts to feign climate policy conspicuously fail to grapple with that truth.”
“Federal regulators are now actively working to counteract the effects of state-level clean energy policy, despite opposition from virtually everyone except the fossil fuel generators that directly stand to benefit. And by doing so, they will crank up costs on 65 million consumers (as a start).”
“US farmers have taken a particularly harsh beating this year from a one-two punch of nasty flooding exacerbated by climate change and a trade war with China.”
