Year 4, Month 5, Day 3: When You Gonna Let Me Get Sober?

The Riverside Press-Enterprise (CA) talks about climate change’s effect on winemakers in the area:

Grape growing in the Temecula Valley Wine Country and other prime wine-producing regions of California would wither by mid-century if greenhouse gas emissions continue unabated and farmers don’t make significant adjustments to their crops, say the authors of a new climate change study.

Under a worst-case scenario, the area suitable for wine production in the Temecula region would shrink by more than half by 2050, according to the work by Conservation International and Environmental Defense Fund, which looked at the impacts of climate change on wine production and conservation. The loss would be smaller if international agreements were reached to reduce emissions, researchers said.

“Certainly in the lowlands it looks like there’s plenty of declining suitability,” said study co-author Patrick Roehrdanz, a researcher at UC Santa Barbara’s Bren School of Environmental Science and Management. “We don’t use the word disappear, but you have to do something to compensate for decline in precipitation.”

Under state projections, temperatures around the Temecula wine country would increase about 2 degrees by 2050 under the lowest emission levels. The average temperature in the area was 62.6 degrees in 1975; by 2050, it is expected to be 67.2 degrees, according to the Cal-Adapt website.

And those projections are the conservative ones. April 21:

As California winemakers assess the impact of climate change on their grapes, they can feel comforted that conservative politicians and media figures believe the greenhouse effect is a liberal hoax. These prominent denialists also believe that decades of careful scientific research on the world’s climate are irrelevant, since scientists are only interested in money. By viewing the climate crisis through ideological lenses, they’ve made it impossible to discuss science without a political slant — and the consequences are going to be devastating to agriculture in America and the world.

The undisputed facts of global warming have been part of climate science for decades, but denialists have steadily hindered and delayed action for the basest of motives: short-term greed. Their radical refusal address the consequences of our greenhouse emissions is now bearing fruit, and as Temecula Valley vintners are coming to realize, it’s going to be a bitter vintage indeed.
