Trump Shows His Fundamental Ignorance About Weather and Climate Change in His Latest Tweet

The Stranger, 1/29/2017

Let me break this down. There are four fundamental components of the earth system that contribute to climatic changes: Milankvitch cycles (wobbles in Earth’s orbit), the carbon cycle (which is fundamentally about ocean circulation, because the ocean dominates the carbon system of the planet), tectonics (including volcanism, the weathering of mountains, and the movement of continental plates), and solar variability (because the sun itself varies in the amount of solar energy produced). Oh, also, you know what else changes Earth’s climate? Asteroid impact events.

Did you read about weather anywhere in this list? No. Of course not. Is it dumb to point to cold weather events as if they debunk climate science? Phenomenally dumb.

Misogyny is a system in which we are all embedded. A system that rewards some people and brutally punishes others, that degrades and diminishes the contributions of some, while celebrating the mediocrity of others. Such systems are comprehensive, with physical and sexual violence at one side of the spectrum to mockery and derision at the other.

Science isn’t just million-dollar instruments in a vacuum; actual people do this work. If you care about science, and our ability to answer questions, steward public policy and improve public safety, then you must care about the people who make up the scientific community. Women, pregnant women, people of color, immigrants and refugees, disabled or LGBTQ, scientists are a diverse, intersectional galaxy of identities, histories and expertise. To advocate for science requires us to address and dismantle institutional misogyny and racism. Anything less is morally disingenuous.

Ocean Mud, Ocean Burping, and Why the Climate Could Change Abruptly 

The Stranger, 10/27/2017

So, short-term changes in climate in the past matter. A lot. Because these events demonstrate pieces of the Earth system (i.e. ice, ocean circulation, volcanoes, ice sheets) that are connected to shifts in the carbon system. One of my favorite positive feedbacks in the system is the idea that the deep ocean “burps” enormous amounts of carbon into the atmosphere, through the upward mixing of deep ocean waters, during abrupt warming events. Another positive feedback that I enjoy is the idea that catastrophic ice shedding, and the resultant unweighting of the continental crust, causes volcanic eruptions, which emit volcanic-sourced carbon into the atmosphere. These examples scratch the surface of how ocean sediments allow for the investigation of past changes in the carbon system. They are vital for understanding celestial mechanics and Earth system feedbacks.

Treading the Fine Line Between Climate Talk and Alarmism

LiveScience, 6/23/2017

Climate concerns are not just about temperature. Big pieces of the Earth's system also change when we alter the global carbon cycle through adding a heat-trapping greenhouse gas "blanket" to the atmosphere. For us in the Pacific Northwest, this means that our snowpack and mountain recreation lifestyles are vulnerable; our rivers of salmon and eagles are vulnerable; and our cold coastlines and marine economies are vulnerable. Put simply, our water and our people are at risk.

We have a lot to lose in the face of unchecked climate warming. Not to be too personal, but have you been to San Diego lately? I would be a different person had I grown up in the heat and glamor of Southern California, rather than in cold, dark, rainy Seattle.


Woman, Scientist…Activist: Female Researchers Take Charge

LiveScience, 8/7/2017

The value of human life is priceless. The people of this country deserve public leadership that values the lives of everyone, not just straight, white, affluent men. In turn, science too is priceless, and people are inseparable from science. The United States needs public leadership that will make decisions using evidence, data and information, not dogma, innuendo and conspiracy.

Because I have the privilege of writing in public, I will use it to say this: It is worth it to do the right thing. It is worth it to show up for the big problems that have been laid at the world's feet: racism, misogyny, climate change, poverty, disease and violence. A better world is possible.

Why Connecting Climate Change with Powerful Hurricanes Is Doing More Damage Than Good

The Stranger, 9/19/2017

We need to poke a hole in this toxic narrative and news cycle around climate attribution. When I say attribution, what I am referring to are the ongoing arguments of attributing specific weather events to climate change: Was Hurricane Harvey caused by climate change? Was the low snow year of 2015, up and down the Cascadian mountains, caused by climate change? These questions—individually—are interesting and important to answer. But the science of Earth system change is not altered by the relative statistical significance of our attribution certainty. Far from it. What’s more, this framing of attribution uncertainty is continually used to support climate action obstruction and denialist voices in our culture. When you hear pandering equivocation about climate and weather events, alarm bells should start ringing in your head. This news cycle is absolutely toxic and we together need to get our broad cultural conversation off this hamster wheel.
