Climate Adaptation
How Hot Will Things Get?
Identifying a realistic worst case scenario is complicated.
How hot will the world be in 2100? The answer partly depends on how much carbon we dump in the atmosphere between now and then. It also depends on how sensitive the climate system is to those emissions. Scientists have used 4.5 °C as the high end of the likely possibilities. That estimate derives from …

What can we learn from the climate disruptions of the previous millennium?
The Little Ice Age wasn’t actually an ice age, but it was a period of markedly colder temperatures that began in the 1200s and lasted into the mid-1800s, with the 1600s a particular low point. It was a time when London winter fairs were regularly held on the middle of a frozen Thames river, glaciers …

Global warming will change much of our everyday lives. Even Feb. 14.
How is climate change connected with Valentine’s Day? In many ways, as it turns out. That’s an indication of the myriad ways in which climate is entangled with our lives. Whether it’s roses and chocolate, or courtship, nothing will remain quite the same as global temperatures go up and up. What about climate change and …

How is one of the world’s largest industries responding to climate change?
As of 2018, the U.S. financial industry contributed $1.5 trillion to GDP. How is the financial sector responding to climate change? The short answer is “slowly so far, but there are signs of progress.” For instance, just last Friday, the NY Times reported that European Central Bank began a strategy review with climate change on …

A potential tool for adaptation and carbon removal, but more research is needed.
The carbonate cycle helps make the oceans one of the largest carbon sinks on the planet. As the oceans’ surface waters mingle with the open air, they absorb enormous amounts of carbon dioxide (CO2), storing it in the water as carbonic acid and carbonates and as limestone on the seafloor. The carbonate cycle is a …

The GOP’s climate denial doesn’t extend to DOD.
Everyone says climate laws can never pass Congress. But there’s a major exception. Each year since Trump took office, Congress has passed climate legislation as part of Defense Department spending. Trump has signed all of those laws. In 2017, there was a congressional finding that climate change is a threat to national security. In 2018, …

Although reducing emissions remains essential, it is time to focus on additional responses
Last month, representatives of all countries gathered for their annual meeting to prevent climate change. Despite the motto “Time for Action,” the New York Times described it as “one of the worst outcomes in a quarter-century of climate negotiations.” Should we be surprised? Disappointed? Despairing? I believe that insufficient cuts in greenhouse gas emissions — …

Conditions in Australia keep getting worse. The government offers platitudes.
Australia is remarkably exposed to climate change and remarkably unwilling to do much about it. Conditions keep getting worse. Yet climate policy in Australia has been treading water or backpedalling for years, as I discussed in an earlier post. Let’s start with the temperature. The Guardian reports that in the year up to July 2019, …

Should the feds be liable for flooding during Hurricane Harvey?
A federal statute bars nearly all claims against the federal government for flooding. Victims of flooding from Hurricane Harvey seem to have found a loophole by claiming that their property was taken without just compensation by flooding. The facts are unusual, but the case raises some deep questions about financial responsibility for flood control. Here …

As international climate action falters, the two climate leaders can fill the void
Note: this post is co-authored with Fan Dai, director of the University of California’s California-China Climate Institute. With the high-profile failure of last week’s UN climate conference in Madrid, the focus of international action on climate change will need to shift to political leaders of key global economies. We attended the conference in Madrid on …
