Come El Niño or La Niña, Climate Change is La Madre of Weather Systems

, climate scientist

It’s getting close to that time of year when weather watchers and water managers start wringing their hands and wondering whether it will be a boy or a girl. The boy is none other than El Niño – that Pacific weather pattern characterized by warm ocean temperatures and heavy precipitation. Last year, we heard all about the monster El Niño that would refill California’s reservoirs. But it never actually materialized. Now, the National Weather Service projects a different winter visitor – La Niña. She’s the opposite of her brother – a weather pattern characterized by dry conditions. Get ready for the headlines: Miserly La Niña steals our water! Read more >

California Just Made Climate Change History. How Did it Happen?

, Western states policy manager

The day before yesterday I sat in the gallery of the California Senate and saw something that just a few weeks ago I wasn’t expecting: Senators casting the final vote on an historic set of bills—Senate Bill 32 (Pavley) and Assembly Bill 197 (E. Garcia)—that reaffirm the state’s commitment to addressing climate change through 2030. After the vote was over, my colleagues and I shared hugs, smiles, and tears as the weight of the accomplishment washed over us. It was a great day. Read more >

Peak Oil, Peak Coal, Peak Deforestation, Peak Emissions…. and Why They’re Not Nearly Enough

, scientific adviser, Climate and Energy

Recent data related to our global emissions of heat-trapping gases suggest that humanity may have reached a turning point, or even several. We may be moving from increasing emissions, to peaking and starting to decline. We could be close to such peaks, or even have passed it, for several of the main sources of greenhouse gases, including coal and deforestation—perhaps even for humanity’s total emissions.

If so, this would be a momentous occasion, reversing centuries of growing global warming pollution. But before we start celebrating, we should realize that peaking is not nearly enough.
