Subnational Climate Action in the UK

As in the U.S., it’s not all about the national government. Not by any means.

Last week, I posted about the British government’s climate policy. In sharp contrast with their American counterparts, British conservatives remain firmly behind the Paris Agreement and supportive of cap-and-trade. In another respect, though, there’s more similarity: in both countries, subnational governments play a key role in climate policy. Here’s what’s happening across Great Britain. Regional …

Regan Hits His Stride

Under Administrator Michael Regan, the Biden EPA is beginning to churn out important new regulatory proposals.

The Trump Administration left a trail of regulatory destruction behind it. Cleaning up the mess and issuing new regulations is Priority #1 for the Biden Administration. Under EPA head Michael Regan, the effort is beginning to pick up steam. EPA has begun the year with several major new regulatory efforts.  No one of them is …

The Least Surprising Disaster in History

Some disasters come as shocking surprises. Climate change is the opposite.

Whatever you want to say about climate change, you can’t say we’ve been blindsided.  The US has had decades to take action against climate change, and we spent nearly half that time deliberately making things worse. Scientists have had reasons for concern about climate change for over a century, and the first government report on …

Why I Was Wrong About Methane

I didn’t think cutting methane was a high priority. Now I do. Here’s why.

I didn’t use to think that eliminating methane emissions should be a priority. True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. In contrast, CO2 emissions cause warming for 2-3 centuries or more. So methane emissions seemed to be something …

Five Myths About Climate Policy

Debate about climate policy is often distorted by misconceptions.

In this post, I want to talk about some of the ideas that make it hard to have sensible discussions about climate policy. I don’t mean outright climate denial.  Instead, I’m talking about less blatant misconceptions that keep many people from thinking seriously about cutting carbon emissions. Myth #1. EPA climate rules are a regulatory …

Biden Can Leverage Larger Trends to Make Climate Progress

Biden can use these three strategies to make major progress on climate issues.

With the next president of the United States finally decided, we can now begin moving on to the work at hand. Joe Biden’s election creates an exciting opportunity for climate action. But there’s one clear hurdle: Unless the January runoff elections in Georgia for two Senate seats deliver surprising success to the Democrats, President-elect Biden …

Another Problem with Cost-Benefit Analysis of Climate Policy

It’s hard to estimate benefits. But it turns out costs are also uncertain.

It’s common knowledge— at least, among people who follow these things — that it is hard to estimate the benefits of a proposed climate policy.  But it’s actually quite difficult to estimate the costs as well. There are three major problems in estimating the benefits of  a proposed climate policy.  First, it’s hard to estimate …

A Continent on Fire Ignores Climate Change

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, …

Coal in 2019: A Tale of Decline

Like Canute & the ocean, Trump may wave his hands, but he can’t stop the tide.

Coal is just about the worst possible way of generating electricity in terms of its climate impacts. It’s also a serious public health hazard due to the particulates, sulfur dioxide, and nitrogen oxides it produces.  Thus, reducing the use of coal is a high priority.  How did we do in 2019? The short answer is …

Climate Policy at Midcentury — Africa

If we’re not careful, African emissions could rival those of China and India today.

If current projections hold and nothing is done to change the trend, Africa could emit as much carbon as the U.S. or even China today. We can’t allow that to happen.
