“We know there are thresholds we don’t want to cross,” says Chris Field. “But we don’t know precisely where they are.”

Soil, writes Rob Jackson, “is a no-risk climate solution with big co-benefits. Fostering soil health protects food security and builds resilience to droughts, floods, and urbanization.”

"We ought to recognize that we have profound limits on the amount of land available and we have to be careful about how we utilize it,” Chris Field says about a new United Nations scientific report.

Research by Noah Diffenbaugh and Marshall Burke is cited in the context of how warming trends have exacerbated global wealth inequality.

“It’s a loss for USDA,” said Earth system science professor David Lobell on the leaving of influential USDA scientist Lewis Ziska.

The Carr Fire, along with California's 2018 Camp Fire, “ended any delusion that humans could keep Mother Nature in check,” according to an Op-ed by Jeffrey Ball, scholar-in-residence at Stanford’s Steyer-Taylor Center for Energy Policy and Finance and a lecturer at Stanford Law School.

According to Katharine Mach, “carbon stored in the biosphere is at risk if we don’t simultaneously get energy, industry, and transport emissions in check.”  

Negative framing of climate change “can be effective in terms of making people aware of the risk, but it’s not necessarily effective in terms of motivating change,” Gabrielle Wong-Parodi said in a July 31 panel.

“It seems...that Californians strongly recognize that climate change is not just about what’s happening to the average thermostat on planet Earth, but it’s really something [that] is driving up across complex hazards,” Katharine Mach says.

Mark Zoback and Jens‐Erik Lund Snee find that wastewater injection from oil and gas operations in the Dallas-Fort Worth area makes faults much more likely to slip.

Marshall Burke, assistant professor of Earth system science, explains how climate change may influence civil conflicts.

“The growing environment is likely to be different 30 years from now in different regions,” says Noah Diffenbaugh. “But it’s an open question how growers and vintners respond to that.”

According to geophysics professor Bill Ellsworth, recent Bay Area earthquakes are on the same fault that caused a 5.8 earthquake in Livermore in the 1980s.

"The general public knows a lot about the actual Moon landing but not much more about its scientific importance," professor Sonia Tikoo-Schantz says in the context of how the Apollo 11 mission has shaped our understanding of the Moon and Earth.

“The main theme from the study is that we should avoid warming on the high end and do everything possible to meet the targets of the Paris Climate Agreement,” says Chris Field.

Geophysicists Greg Beroza, Bill Ellsworth and  Simon Klemperer comment on recent earthquakes. “We expect more earthquakes in the next 20 years than in the past 20 years,” Klemperer says.
