Veille 2.1

Referring to the Paris Agreement’s target of keeping Earth from warming no more than 1.5 degrees Celsius since the Industrial Revolution, the number has become a rallying cry for climate advocates and scientists, who say the goal is humanity’s best bet on avoiding the most catastrophic outcomes of climate change by the end of the century. Venturing even 0.5 degrees past that threshold could drastically increase the frequency and severity of extreme weather, biodiversity loss, famine and water scarcity, as well as make it more likely that tipping points accelerate warming further, climate scientists say.

Several nations plan to build new coal power plants, with China alone approving nearly 100 gigawatts. Each gigawatt is the equivalent of installing more than 3 million solar panels.

Research published this summer found that falsehoods about global warming continue to flourish on social media sites and are often framed through the lens of Western culture wars, placing climate change alongside other hot button topics like gay and transgender rights and gun control. A separate analysis released last month found “a sprawling online network” of Spanish speakers on Twitter, TikTok and other major social platforms who “consistently amplify” climate misinformation and other right-wing conspiracy theories.

Over the past 20 years, cement manufacturers have quietly doubled their carbon dioxide emissions, highlighting a sector that has received relatively little public scrutiny despite contributing nearly three times as much to global warming as the airline industry. With cement production only expected to increase through mid-century, a growing number of people are now calling for a more concerted effort to tackle concrete’s expanding carbon footprint.
