Life in the Greenhouse: Daily Summaries Delivered
by Carbon Accounting, Reporting, and Management Lab
Life in the Greenhouse documents the effects of the rising concentration of carbon in our atmosphere. Season Two: Trees Remember shares the story of scientists studying what trees in the Southwest remember about drought. We investigate what tree memory means for the concentration of carbon in our atmosphere and for human life in the greenhouse we call Earth. In Season One, we use greenhouse gas accounting as a tool to analyze the hype coming from oil and gas companies about their clean energy developments, providing a crash course in emissions measurement and reduction along the way.

S2 E5: Memories, Findings, and the Future
It’s time to ask a new, but related, question about trees and memory: What do humans remember about trees? Team leader Dr. Kiona Ogle shares about her home landscape, both what she remembers and what she predicts for the future of her corner of the Southwest. Then, she shares a sampling of what the team has learned so far in their research on legacy effects. You’ll hear how climate change has hampered this team’s research on exactly that topic.

S2 E4: The Carbon Cycle Connects Us
What does research on tree memory have to do with humans? In episode four, we answer this question by discussing the carbon cycle and how both trees and humans fit into it. Carbon is a key building block of both trees and humans—it’s also in our food, clothing, and energy systems, and it touches all of human society. We talk about trees’ role in humanity’s future as we rearrange Earth’s carbon, and we talk about what tree memory has to do with it all.

S2 E3: Tree Growth Recipes with CARDAMOM
How can scientists measure drought impacts? How do they know what’s truly an effect of drought vs. what would have happened anyway in a forest? In episode three of Season Two: Trees Remember, we meet two scientists from NASA’s Jet Propulsion Laboratory who combine satellite data with computing to discover the math behind forest behavior. They’re figuring out how drought affects a forest's ability to grow—to store carbon—not just during a drought, but years later.

S2 E2: Tree Ring Detectives
How do scientists gather information from tree rings? In episode two of Season Two: Trees Remember, we take you with us as two scientists gather tree core samples in the forest and then process them into a treasure trove of information about tree memories of past climate. We explain how these scientists use tree rings in a unique way compared to past tree ring studies. And we explore why this team focuses on ecosystems where water is scarce and why that matters for humans.

S2 E1: What is Tree Memory?
What is tree memory? And why is one group of curious scientists dedicating years to studying it? In episode one of Season Two: Trees Remember, we answer those questions and explain why understanding tree memory in the Southwest is especially important for understanding humanity’s future.

S1 E4: Arriving at an Answer
Throughout this season we have been diving into a central question: Is it time to start calling oil & gas companies energy companies? In the final episode of season 1 of Life in the Greenhouse, we finally arrive at an answer through three interrelated conversations spanning greenhouse gas disclosure regulations, low-carbon transition plans, and the role of oil & gas in international climate negotiations.
