Last week I cited older research showing that air pollution nearly doubled the risk of dying from SARS, but now the #COVID19 connection is in: "A small increase in long-term exposure to [particulate matter] leads to a large increase in COVID-19 death rate" thehill.com/policy/energy-…

Just to be clear, the carbon in the atmosphere is at a 15 million year high. So, no.
If you want to know what's really been happening to carbon emissions and air pollution as a result of the pandemic, and what that means for us long-term, I unpack it here:
And how do we know we're at a 15-million-year high? Thanks to the field of paleoclimatology that uses ice cores, sediment records, stalactites in caves, and many more fascinating ways to track the earth's history. Learn more here: ncdc.noaa.gov/data-access/pa…

As the economic slow-down due to the coronavirus pandemic shutters industry, air pollution and carbon emissions are dropping. A lot of people have asked what this means for carbon emissions and climate change. Here is a short explainer. (thread)
First, don't look to short-term monthly concentrations for evidence of a drop in human emissions. Over timescales shorter than a year, CO2 is primarily controlled by the biosphere which releases (and absorbs, which is key) ~10x more carbon than humans.
Second, the long-term upward trend in CO2 is the result of CUMULATIVE, not annual emissions: every single brick we've been putting on the pile every month since the dawn of the Industrial Era. Today, adding a brick 25% smaller for 1-2 months isn't going to make a big difference.

Over the last few years, I've been deliberately transitioning most of talks I give (and as many meetings as I can) to virtual, low-carbon presentations. Here are a few fast + easy hacks I use to up the quality of a video class, presentation, or meeting. thread/
1/ Move your camera to at or slightly above eye level. If you're using a laptop, raise it on books. Here's what a big difference this makes. I took these two pictures right now, just seconds apart. It's real.
2/ Make sure there is light on your face. It's as simple as facing a window or moving a table lamp in front of you. Here's the difference it makes.
