Arctic Futures: White Shield or Blue Economy
Multiplying proposals for ice restoration face geopolitical obstacles
Ice-thickening. Glacier curtains. Cloud brightening… Proposals for Arctic climate interventions seem to be multiplying by the day. The changing climate is not only shrinking ice caps and ice sheets, but also bringing much greater than average temperature rises in polar regions. These impacts particularly disrupt the lives and livelihoods of Arctic Indigenous Peoples. Arctic impacts …

In this UCLA Emmett Institute webinar, panelists discussed the climate implications of the 2024 election from the state, national, and international perspective.
Climate certainty. Legislative action. Whipsaw regulations. An exodus of civil servants. Chinese leadership despite being the world’s largest emitter. Those are a few of the possible outcomes of the Nov. 5 presidential election, according to our panelists. More than in any previous election, the two major candidates’ track records on environmental policies are well-established and …

How should the US compete with Chinese green development?
China’s dominance in clean technologies (solar, wind, electric vehicles, batteries) has been in the news recently (see, e.g., here and here). China accounts for more than 80% of global manufacturing capacity for solar products and batteries. Chinese companies produce 65% of EVs globally. The US has responded to this both with measures to improve US …

CONTINUE READINGEarth system tipping events now seem inevitable – what does this mean for climate governance?
Building meaningful earth system governance creates multiple new research challenges
A tipping point is a system threshold beyond which change becomes self-perpetuating until a qualitatively different stable state is reached. For example a rainforest turns into a grassland, or an ice sheet melts completely. Such shifts are non-linear, and practically irreversible. Fears that growing human impacts might push aspects of the global climate past such …
CONTINUE READINGChina, Climate, and Clean Energy
China seems to have leap-frogged the U.S. on clean energy. We need to catch up.
In 2023, China accounted for about 60% of the world’s additions of solar and wind power, and of electric vehicles. The U.S. will need to make a major effort to catch up. Otherwise, we risk being shut out of important global markets and giving China an opening to influence developing countries.

These interlinked technologies are crucial to the energy transition. Here’s their history.
To fight global warming, we need to largely eliminate the internal combustion engine as a form of transportation. We need battery technology for this and to store electricity, because wind and solar power are intermittent. These technologies didn’t appear out of thin air. Here’s the story of their rise

Sharing my lessons
After many years of work, the Stratospheric Controlled Perturbation Experiments (SCoPEx) Advisory Committee concluded our work earlier this year after the research team at Harvard made the decision to cancel the experiment. I was a member of the Advisory Committee for much of its time, serving as chair and co-chair of the committee for …

As the saying goes, “It’s the economy, stupid.”
Renewable energy costs have plunged to an extent few people realize. If cellphone prices had dropped as fast since 2010 as the cost of solar power, you could buy a new iPhone for about thirty bucks today.

By any measure, it has been an eventful four years for climate policy, with billions in spending and many major regulations finalized. Here’s a timeline of the Top 30 actions.
In light of President Biden’s withdrawal from the 2024 presidential race yesterday, we thought it was appropriate to update this piece about the climate legacy of the Biden-Harris Administration. In his four years in office, Donald Trump rolled back essentially every existing federal policy to limit climate change. The picture under the Biden Administration has …

Carbon border adjustment mechanisms are increasingly the talk of Washington. UCLA Law’s Kimberly Clausing explains some of the options on the table.
There’s a big, important tax debate looming next year—one with opportunities and risks for climate policy, particularly the idea of a carbon tax. It can be hard to see this debate thanks to the daily churn of the 2024 presidential election, but it’s there on the horizon if you squint. For one thing, we’ll likely …
