In the lab 😁 finally getting around to testing a new piece of equipment - LI-COR DIC analyzer. Love the nice peak! This will support our climate change research on fish! @utscbiology.bsky.social @utsc.bsky.social Thank you to CFI for funding to buy this incredible machine!

From 1.5C to 2C of global warming is an increase by 33.3 percent. Many people assume that the negative impacts of this would also increase by only 33.3 percent. Unfortunately, that is not the case. The increase is non-linear. This is one of the biggest missing pieces in public climate literacy.
