Life in the Greenhouse

About Life in the Greenhouse

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 E6: We Remember

   What other archives hold information about tree responses to climate extremes, like drought? What about human memory and Indigenous knowledge? In this final official episode of Season 2, you’ll hear from two Indigenous voices. Nikki Cooley shares about Indigenous elders as long-term monitoring networks, and Regina Lopez-Whiteskunk explains the impacts of drought on the Ute people and guidance for seeking knowledge from Tribal elders. Along the way, you’ll also hear from the scientists working to decipher what trees remember.

   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

   NASA scientists use satellite data and computing to quantify drought's long-term impact on forest growth and carbon storage, revealing insights into forest behavior.

   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.

   S1 E3: Shades of Green in the Carbon Offset Market

   Carbon offsets have been the center of some high profile scandals over the past few years, but what else is there to these stories? Why does the voluntary carbon market exist and how do we know if carbon offsets are actually making a difference?

   S1 E2: Navigating Net Zero Narratives

   Countless companies, including fossil fuel companies, have pledged to achieve net zero emissions. This sounds like great news! But there’s more to the story. We’re talking about what net zero really means and how a company could actually get there while explaining the importance of the Science-Based Targets Initiative.

    S1 E1: Easy as Scope One Two Three

    Extreme Makeover: The Oil and Gas Edition is afoot. The companies we’ve long known as fossil fuel companies are telling us they’re actually energy companies committed to finding solutions to climate change. We’re not so sure, so we’re parsing it out using greenhouse gas accounting and discussing the concept of emission scopes along the way. Show Notes: 1:40 The Carbon Accounting, Reporting, and Management Lab (https://carml.rc.nau.edu/) (CARML) at Northern Arizona University 2:46 “And because we are so dependent on these fossil fuels, we consume A LOT—just take oil for example. Around the world humans burn about 4.2 billion gallons (https://www.iea.org/reports/oil-2023) of oil every single day. 4:36 Current concentration of carbon dioxide in the atmosphere measured at Mauna Loa, Hawai’i (https://gml.noaa.gov/ccgg/trends/monthly.html) 6:42 Keeling Curve (https://keelingcurve.ucsd.edu/) 12:57 Drilled podcast homepage (https://drilled.media/) Petroganda (https://drilled.media/investigations/petroganda): Drilled’s series on “The fossil fuel industry’s favorite narratives.” This is the series we reference in Episode One when Erica says “You can check out another great podcast called Drilled for fantastic reporting about how oil & gas companies, particularly ExxonMobile, have a long history of spreading misinformation about climate change. 18:12 "Most captured CO2 is used in enhanced oil recovery" 2022 IEEFA analysis (https://ieefa.org/resources/carbon-capture-has-long-history-failure) 18:40 “[T]ools we can use to investigate the question of branding claims vs. reality” Paper (https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0263596): Li M, Trencher G, Asuka J (2022) The clean energy claims of BP, Chevron, ExxonMobil and Shell: A mismatch between discourse, actions and investments.

Similarly, we observed increasing tendencies toward strategies related to decarbonization and clean energy. But these are dominated by pledges rather than concrete actions. Moreover, the financial analysis reveals a continuing business model dependence on fossil fuels along with insignificant and opaque spending on clean energy. We thus conclude that the transition to clean energy business models is not occurring, since the magnitude of investments and actions does not match discourse. Until actions and investment behavior are brought into alignment with discourse, accusations of greenwashing appear well-founded. “Oil Companies Are Trying to Rebrand Themselves on Social Media (https://www.nrdc.org/stories/oil-companies-are-trying-rebrand-themselves-social-media)” Reporting from the Natural Resources Defense Council (https://www.nrdc.org/) contrasting oil companies’ ad campaigns with how they spend their lobbying dollars, from 2019 21:53 “For example, burning one gallon of gasoline in a motor vehicle results in about 20 pounds of carbon dioxide emissions.” See the EPA’s GHG Emission Factors Hub (https://www.epa.gov/climateleadership/ghg-emission-factors-hub). 31:35 “Today, we're zooming in on ExxonMobil's recent $60 billion acquisition of Pioneer Gas (https://corporate.exxonmobil.com/news/news-releases/2023/1011_exxonmobil-announces-merger-with-pioneer-natural-resources-in-an-all-stock-transaction) in October 2023.” 35:43 The Climate Registry (https://theclimateregistry.org/wp-content/uploads/2023/06/2023-Default-Emission-Factors-Final-1.pdf) emission factors (2023)

    Life in the Greenhouse: Season 1 Teaser

    Climate change is a problem driven by fossil fuels. And yet, companies we’ve long known as producers of fossil fuels are rebranding themselves as key players in the fight against climate change, all while spending billions of dollars exploring for more oil & gas. We’ll spend our first season examining this rebrand using greenhouse gas accounting as our investigative tool.
