Calling for a "clean energy revolution," the former vice president lays out a path to invest $5 trillion over 10 years to achieve the renewable energy goals. Nearly $1.7 trillion of that would be federal dollars, which Biden's campaign says will be paid by undoing the tax cuts enacted by President Trump and congressional Republicans.
People are putting nature in more trouble now than at any other time in human history, with the risk of extinction looming over 1 million species of plants and animals, scientists said Monday. But it's not too late to fix the problem, according to the United Nations' first comprehensive report on biodiversity.
Geoengineering -- the deliberate effort to manipulate the Earth’s climate in an attempt to offset, delay, or slow global warming -- has slowly transformed from a pie-in-the-sky idea to a serious concept that may well be attempted one day. A wide variety of schemes have been proposed for how we might cool the Earth, but many of these would require the development of technologies far beyond our current capability.
Ranking member Eddie Bernice Johnson (D-Texas) issued a statement after the election results Tuesday night stating that, if elected chairwoman, she wants to restore the credibility of the science committee “as a place where science is respected and recognized as a crucial input to good policymaking.” Johnson said that includes acknowledging that climate change is real, “seeking to understand what climate science is telling us, and working to understand the ways we can mitigate it.”
New observations from NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission is providing insight into how Earth is responding to rising levels of heat-trapping gases in the atmosphere, and what this means for our future climate. Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future.
Addressing global climate change requires clean energy technologies that are cost- and performance competitive with fossil fuels without subsidies. Characterized by carbon prices, subsidies, and mandates, the dominant clean energy policy approaches in the United States and internationally are not likely to meet this goal. Only a cohesive and aggressive innovation strategy can produce the needed and rapid development of affordable clean energy options the entire world wants to purchase.
