You May Have Forgotten About Climate Change. But It Hasn’t Forgotten About You

Denial is a great coping mechanism. Until reality turns around and bites you.

Climate change is, apparently, passé.  Democratic politicians are avoiding the topic and dialing back ambitious plans to reduce emissions.  The President apparently doesn’t think it exists, and the government’s official position is that its effects are too uncertain to worry about. Denial isn’t the world’s best coping mechanism, but it works, at least temporarily.  The problem is that, while sometimes that lump you were worried about does go away, sometimes it keep growing and getting harder to treat. In the end, reality doesn’t much care whether you believe in it.

What the Disappearing Danube Could Tell Us About the Colorado

A cracked, dry riverbed in the foreground with a large river and a bridge in the background; a boat is visible on the water under a gray, overcast sky.

Today’s drought may not be the worst-case scenario for the Colorado

What’s happened to the Danube is a scary reminder that what we’re seeing today on the Colorado isn’t necessarily the worst case.  The situation on the Danube is truly dire. The “Blue Danube” memorialized by the Strauss waltz is now only nine inches deep in Budapest.  Cargo ships have come to a halt.  Nuclear reactors have shut down for lack of cooling water. Meanwhile, the Colorado is suffering from the worst drought in at least 1200 years, raising fears about the fate of its shrinking reservoirs. And things could get worse.

Never Give Up! Every Ton of Carbon We Can Cut Still Matters

A figure demonstrates the possible changes in Celsius of global temperatures at 1.5, 2. and 4 degree Celsius increased in global warming.

It’s easy to be disheartened when we miss climate targets. But climate change isn’t a yes/no thing. It’s a matter of degree.

It’s easy to lose heart about our prospects for limiting climate change. The US has pulled out of international climate negotiations. Most of the countries that joined the Paris Agreement have missed targets , targets that weren’t aggressive enough in the first place.  The 1.5 °C target is already basically out of reach.  Is time to give up on slowing climate change and focus on adapting to it?  The answer is no.  Here’s why.
Climate change is a matter of degrees. That sounds like a truism or a pun, but it’s true in a deeper sense. There is no point past which further warming becomes irrelevant. degree, and every fraction of a degree makes things that much worse.

An “Unprecedented” Heat Wave is Just the Start

A sign in front of the rocky base of a mountain slope reads "CAUTION! EXTREME HEAT DANGER"

The Drain is a weekly roundup of environmental and climate news from Legal Planet.

Dust off your fan or set the thermostat for your heat pump. A heat wave is in the forecast for the western U.S., bringing 90-plus degree heat to much of California and records are likely to fall. Temperatures that are 20-30 degrees above normal for this time of year are on tap starting today. It’s …

Climate Inaction is an Affordability Problem

A U.S. map shows estimated flooding losses per household by county, using colors from yellow (low, $500) to dark purple (high, $1,500+). Highest losses are concentrated in the eastern and southern regions.

The costs of climate change, especially those from climate-related natural disasters, are already substantial for US households.

This post is authored by UCLA Law’s Kimberly A. Clausing along with guest contributors Christopher R. Knittel and Catherine Wolfram. Many of us have seen large increases in our homeowner’s insurance premia in recent years – yet another cost increase that is putting strain on homeowners and driving up rents. In forthcoming work for the …

How to Dissent? Learn American History

LA Public Library

The Drain is a weekly roundup of environmental and climate news from Legal Planet.

It sounds cliché, but when you face a crisis, it helps to remember times that you’ve overcome adversity. That’s the power of history. And it’s one of the reasons I think the new PBS documentary “Clearing the Air: The War on Smog” is crucial to share right now. In the 1940s, dark, smoky clouds crept …

Why is EPA at War with Its Own Employees?

The Drain

The Drain is a weekly roundup of environmental and climate news from Legal Planet.

While many of us prepared to celebrate Independence Day last week, a group of employees from the Environmental Protection Agency were bravely speaking out about what they see as their boss “recklessly undermining the EPA mission” of protecting human health and the environment. In a now-infamous letter sent to EPA Administrator Lee Zeldin, hundreds of …

A Landmark Geoengineering Conversation in the Global South

The UCLA Emmett Institute helps sponsor and organize the Degrees Global Forum, the largest event of its kind to date.

I post periodically about developments in the debate over solar geoengineering (SRM) and its potential role in response to climate change. News accounts may suggest that this debate moves fast, but it has three enduring, large-scale themes. First, SRM presents high stakes for climate risks and response – which most governments thus far have been …

Help Shape the Bay Area’s Climate Future

Seeking input from local leaders, organizations, and individuals to shape California’s Fifth Climate Assessment for the region

The California Climate Change Assessment is a key initiative to understand and address the state’s climate impacts and build resilience through informed decision-making. California’s Fourth Climate Change Assessment included a series of technical reports, regional summaries, and a statewide synthesis covering key issues such as extreme heat, wildfires, and sea level rise—providing critical guidance for …

Field Notes from India: Climate Adaptation from the Ground Up

Two days with climate educators in Ahmedabad, India changed my understanding and appreciation of climate resilience.

I spent last week in New Delhi, participating in the conference, India 2047: Building a Climate-Resilient Future. Academics, civil society, and government officials were divided into groups focusing on science, health, labor, and the built environment. It was fascinating to explore the daunting challenges India will face as many of its regions confront daily temperatures …
