And because major volcanic eruptions can have the same effect, there are some real-world data to anchor the idea. The place and time for the experiment are still to be determined, but it would be a baby step toward showing whether artificial stratospheric particles could help cool the planet the way eruptions do naturally. But the idea of using a technological fix for climate change is controversial. Talking about - let alone researching - geoengineering has long been considered taboo for fear that it would dampen efforts to fight climate change in other ways, particularly the critical work of reducing carbon emissions. That left geoengineering on the fringes of climate research. But people's attitudes may be changing, Keith says. He argues that while geoengineering by itself cannot solve the problem of climate change, it could help mitigate the damage if implemented carefully alongside emissions reductions. In 2000, Keith published an overview of geoengineering research in the Annual Review of Energy and the Environment, in which he noted that major climate assessments up until that point had largely ignored it. He noted that in the past, Russia has used military buildups as a scare tactic. “We don’t have any misunderstanding with the president, but I just deeply understand what is going on in my country, just as he understands what is going on in his country,” Mr. Zelensky said of Mr. Biden. The drumbeats of war, he added, could contribute to domestic instability and economic troubles that would heighten the risk posed by Russia. Mr. Zelensky took issue with decisions by the United States and Britain to withdraw nonessential diplomatic staff from Ukraine, which he suggested set an unduly alarming tone. “I don’t think we have the Titanic here,” he said. The United States has been more outspoken than many European nations about the threat of a Russian attack, even as the Biden administration has tried to project a unified front with NATO allies. The Pentagon said that in the past 24 hours, more Russian forces were being moved into the region. tlatelolco 68
