Marysa Laguë was awarded the inaugural Andrew Slater award for best performance by a student or postdoc at the Land Model Working Group meeting this week at the National Center for Atmospheric Research.
I was recently interviewed by Michael White, the editor for climate topics at Nature, for his Forecast Podcast. The conversation spanned broadly (!) from the recent fires in Northern California, to my trajectory of becoming a scientist, to how we can compare models with data, through sexual harassment in sciences.
You can listen to the interview here.
The Ecoclimate lab will be giving a few talks at the upcoming Ecological Society of America Meeting next week in Portland, OR. If you are attending the meeting we hope to see you there!
Portland Blrm 258 – Ecosystem-climate interactions and ecoclimate teleconnections
A new paper by Greg Quetin in Journal of Climate
Many of us probably have some intuition that a plant growing on the hot dry edge of a desert will not get greener in a warmer year, but will get greener in a wetter year. But what about the hot wet tropics where there is plenty of water, it is scorching hot, and clouds often block the sun?
Using satellite measurements of greenness, estimates of air temperature, and a dataset of rainfall we answer the following questions at each point of the Earth. Does a plant get greener in a warmer year? How about in a wetter year? With these observations we then quantify how the interactions of plants and climate are changed by the annual temperature and precipitation of where the plant grows. Spoiler: plants generally get greener during warmer years in these hot wet environments. Finally, this behavior of getting greener during warmer years starts when plants receive around 2000 mm/year of rainfall.
Drawing from this new analysis, we can use the climate of where the plant grows to propose mechanisms driving the plant climate interactions. For example, to explain how plants mostly get greener when it is warmer in hot wet climates we propose that it happens because there is additional sunshine during warmer years. Increased sunlight provides more energy for plants to photosynthesize and offsets any negative effects of increased temperature. In our paper we detail the plant climate interactions across the globe, proposing mechanisms in cold, hot dry, hot wet and cool wet climates.
I was interviewed by David Hyde from KUOW about my reasons for signing a letter to Scott Pruitt urging him to act on climate. We also talked about that time a US border agent told me climate change was a hoax. Check out the radio piece here: kuow.org/post/she-had-c…
More on the letter:
30 leading scientists (led by Nobel laureate Mario Molina and others) respond to EPA chief Scott Pruitt’s doubt that human-emitted CO2 is a cause of warming.
The letter notes that “focusing on disagreements over details, or among a few individuals on the margins of consensus, or on the uncertainties that are part of any accurate statement of scientific knowledge, misses the big picture: human beings are changing the Earth’s climate. This key conclusion follows from the basic laws of physics. Just as there is no escaping gravity when one steps off a cliff, there is no escaping the warming that follows when we add extra carbon dioxide and other greenhouse gases to the atmosphere”

A new lab paper led by postdoc Elizabeth Garcia is out now in PLOS one.
In the paper we quantify how forest die-off events can impact climate across the globe, and how this has consequences for distant ecosystems. We looked at forest die off in North America, as well as in the Amazon forest in a coupled land-atmosphere-slab ocean climate model.
Here are our main take-home points.
