The latest IPCC assessment raised alarm about the rate at which manmade emissions are contributing to climate change. Much of the focus for action is on reducing levels of carbon dioxide, however there is a more potent greenhouse gas, methane, produced by natural and industrial processes which, as Roland Pease tells Drew Shindell of Duke University and lead author on the Global Methane Assessment, is relatively easy to target for reduction.
Gut microbes and behaviour Roland speaks to neuroscientist John Cryan of University College, Cork in Ireland who is interested in the effects our gut microbes can have on our behaviour. It’s an unusual connection and one which he’s been experimenting on in mice. By feeding the faeces of younger mice to older ones he has found that the older ones’ took on some of the younger ones’ behaviour.
Ball lightning Ball lightning is the stuff of legend and the supernatural. And yet there are many reported sightings of this phenomenon. Texas State University's Karl Stephan explains to Roland that he is keen to uncover the science behind these observations. He’s running a crowd sourcing project encouraging people to contribute video recordings of any ball lightening events they might observe.
Chile mummies And Chile is home to the oldest known mummies in the World. UNESCO world heritage status has been given to a collection of around 300 mummies from Chile’s northern deserts. The mummies of babies, children and adults are thought to have been created in response to arsenic poisoning in the region around 7,000 years ago.
How can smart tech tackle climate change? Humans are responsible for emitting over 40 billion tonnes of carbon dioxide into the atmosphere every year – and we all know that we need to reduce that figure to prevent devastating climate change. Listener Saugat wonders whether smart technology and artificial intelligence can help us do this more quickly?
Green energy will go a long way to tackling the problem, but integrating wind and solar into our current electricity grid is complicated. Marnie Chesterton hears how AI is being used at a wind farm on the island of Orkney to predict periods of high winds, so that excess energy can be turned into hydrogen and stored, then converted back to electricity when there’s greater demand.
Digital mirrors are also playing a major role in optimising performance, and scientists say cloud-based “twins” of physical assets like turbines can improve yield by up to 20%, allowing engineers to identify problems via computer without ever having to be on site.
Marnie visits an intelligent building in London’s financial district where sensors control everything from air-conditioning to lighting, and machine learning means the building knows which staff will be on which floor at any given time, switching off lifts that are not in use and adjusting ventilation to save on power. Its designer says incorporating this kind of digital technology will help companies achieve net zero more quickly.
And in India, more than half the population are involved in agriculture, but the sector is plagued by inefficiency and waste. Tech start-ups have realised there’s potential for growth, and are using drones to monitor crop production and spraying, giving farmers apps which help them decide when and where to fertilise their fields.

Air pollution is estimated to cause 7 million deaths a year and cost the global economy nearly $3 trillion. But is the true cost even higher? Stephen Dubner explores the links between pollution and cognitive function, and enlists two fellow Freakonomics Radio Network hosts in a homegrown experiment.
Jeffrey Shaman returns to TWiV to explain how epidemiologists measure SARS-CoV-2 movement among humans, including calculation of the reproductive index, secondary transmission, and what factors affect transmission.

The vaccine mandates are coming. In New York, you’ll now need to prove you’re vaccinated to go to a restaurant, bar, gym or entertainment venue. Other American cities are considering similar rules. In the last week, more businesses are announcing rules about vaccines. How would it actually work to enforce these rules at millions of businesses?
Also: If you have a smartphone, listen up. This week, Senator Ron Wyden (D-OR) joins the panel to discuss how a high-profile member of the U.S. Conference of Catholic Bishops was outed by a small publication that obtained commercially available data from his phone to figure out where he was using Grindr. Should you actually start reading those terms of service now? Should the government protect and regulate how our data is collected, bought and sold, or is it best left up to consumers and the companies themselves? Senator Wyden walks us through his ideas for that and an amendment to the infrastructure package that would impose new rules on cryptocurrency transactions. Tens of billions of dollars (an important revenue stream for the infrastructure bill) are at stake.
Then: the panel catches up on the nationwide eviction moratorium, this week’s damning report on New York Governor Andrew Cuomo, and why we really need to stop stanning our elected officials (looking at you, “Cuomosexuals”...).
TWiV reviews SARS-CoV-2 infection of wild white-tailed deer in the US, mRNA vaccine-mediated protection by spike-specific T cells before detection of neutralizing antibodies, and recovery from SARS-CoV-2 infection in T-cell depleted rhesus macaques.

Donald Trump fails to stop Republicans from supporting the bipartisan infrastructure deal, Joe Biden and the Democrats look to budget reconciliation as their last best chance to fight climate change, Crooked Media Political Director Shaniqua McClendon joins to talk about Vote Save America’s No Off Years campaign, and New York Times tech reporter Sheera Frankel talks to Jon Lovett about her new book about Facebook, “An Ugly Truth."
We started the Covid pandemic at negative oil prices. Today, benchmark prices are above $70. And top oil companies are reporting billions of dollars in profits.
And now there is more scrutiny than ever on how they’re going to spend that money.
Activist shareholders are starting to get climate champions on oil major board seats -- most notably, climate tech investor and former wind executive Andy Karsner on Exxon Mobil’s board.
A dutch court is now forcing Shell to reduce the emissions from its products by 45%, after a successful lawsuit from environmental groups. Oil executives now have their lawyers on speed dial.
And big asset managers, like BlackRock, which lend to many of the world’s energy giants, are scrutinizing their climate plans.
So what does it all amount to as oil markets rebound?
Ed Crooks, the vice chair of Americas at Wood Mackenzie, joins us this week to discuss.
Plus, we’ll talk about a new report card on America’s infrastructure. It’s a slight improvement, but the grade is still pretty awful.
And, carbon offsets are going up in flames. Literally. What comes next for forestry offsets?
