California Today: California Today: The Dominating Dodgers

Supported byU.S.California Today: The Dominating DodgersPhotoYu Darvish, among the most talented pitchers in baseball, is the latest star to join the Dodgers.Credit Kevin C. Cox/Getty ImagesGood morning.(Want to get California Today by email? Here’s the sign-up.)Today’s introduction comes from James Wagner, who covers baseball for The Times.The baseball season is a six-month slog: 162 games played over 183 days, many over the hot summer months. More than anything, it is a battle of attrition. Last year, teams used an average of 25 pitchers and 45 hitters to make it through the season. […]

Big oil just got a pass on methane reporting.

In some parts of the country, the season just breezed in three weeks ahead of schedule. Balmy weather may seem like more good news after an already unseasonably warm winter, but pause a beat before you reach for your flip-flops.

According to the “spring index,” a long-term data set which tracks the start of the season from year-to-year, spring is showing up earlier and earlier across the United States.

The culprit behind the trend? Climate change. And it’s bringing a batch of nasty consequences. Early warmth means early pests, like ticks and mosquitoes, and a longer, rougher allergy season. Agriculture and tourism can be thrown off, too. Washington D.C.’s cherry blossoms usually draw crowds in April, for instance, but they’re projected to peak three weeks early this year.

Spring isn’t shifting smoothly, either. It’s changing in fits and starts. Eggs are hatching and trees are losing their leaves, but temperatures could easily plunge again, with disastrous consequences for new baby animals and plants.

Play this out another 80 years, and it’s easy to imagine a world out of sync. Sure, your picnic in December sounds nice. But bees could lose their wildflowers, and groundhogs may never see their shadows again.

Millennials Looking for a Place in the Emerging Green Economy

This is the season when my colleagues and I spend a lot of time reviewing applications for graduate school, most of which were submitted after the recent election. I direct two master’s programs at Columbia, one a Master of Public Administration in Environmental Science and Policy and the other a Master of Science in Sustainability Management. Together, the two programs enroll about 300 students. Columbia also has programs in climate and society, sustainable development and development practice. Among this student body there is a deep sense of unease with the direction of the U.S. federal government, but that is coupled with a high degree of confidence in the importance of the emerging green economy.
