A Climate Change Primer
The Climate Change Primer Series sets forth key concepts relevant to understanding climate change and our global energy system. Topics covered include how we know that human-caused climate change is really happening, where our emissions come from, the costs of climate change, frameworks for projecting future climate scenarios, the social cost of carbon, and summaries of potential solutions.
Carbon Dioxide Removal (CDR)
In order to reach global net-zero emissions by 2050, we must remove CO2 from the atmosphere as well as prevent further emissions. Carbon Dioxide Removal (CDR) can be accomplished naturally – through fores...
Biofuels: An overview
Biomass – such as corn or switchgrass – can be converted into liquid transportation fuels, or biofuels. Biofuels are attractive because they result in significantly fewer emissions than fossil fuels...
Climate Policy Levers
Which climate policies will help countries transition to net-zero emissions? What are the pros and cons of these policies, and how does the United States compare to the rest of the world in implementing a carbo...
Social Cost of Carbon
How are the benefits of new climate policies weighed against the costs of their implementation? Climate economists and scientists have created a value called the social cost of carbon in order to better underst...
Costs of Climate Change
It's hard to put a dollar number on the destruction of the great barrier reef. And we don't know exactly how much it's going to warm where. But we can take physical estimates and quantify the range of monetary impacts that climate change might cost. In this video, we examine the projected costs of climate change in human health, agriculture, sea level rise and extreme weather, labor and energy, and migration.
How dirty are we?
Global greenhouse gas emissions reached a staggering 52 gigatons of CO2-warming equivalent in 2020. Our episode puts this number into historical context, parses our global emissions by country and economic sector, and delves into the key economic and demographic drivers of emissions worldwide.
How we know it’s happening
How do we know the climate is changing? How do we know that change is being caused by human activities? Climate Now video hosts Ozak Esu and James Lawler delve into the science that answers these questions with MIT climate scientist Kerry Emanuel.
In this series, we examine a wide spectrum of climate and energy technologies and processes. Videos feature subject matter experts who help us explain technical function, cost, scalability, and other pros-and-cons. Technologies covered include biofuels and feedstocks, nuclear energy, direct air capture, carbon capture and sequestration, wind, solar, battery technologies, forest carbon, soil carbon, waste processing, cement production, steel production, green buildings, hydrolysis, and others.
Oceans for CO2 removal & storage: What, why and how?
Using carbon dioxide removal (CDR) strategies to mitigate climate change is a land-intensive endeavor. To capture one gigatonne of CO2 through direct air capture requires a facility & energy production foot...
In order to reach global net-zero emissions by the middle of the century, modeled pathways project that wind energy will need to be a primary source of electricity, accounting for 19-43% of global electricity p...
Carbon Dioxide Removal: Mineralization
There are several methods of removing carbon dioxide from the atmosphere – both natural and technological – and each method has its tradeoffs. Carbon mineralization is the most secure option for car...
Carbon Dioxide Removal: Carbon Capture and Storage, Part II
Carbon Capture and Storage (CCS) has the potential to remove billions of tons of CO2 from the atmosphere annually, which we will likely need to reach global climate targets. In the first of our two-part ser...
Carbon Dioxide Removal: Carbon Capture and Storage, Part I
What if we could remove the carbon we have emitted into the atmosphere? Can we capture our CO2 emissions before they are even released? In Part I of our two-part Carbon Capture and Storage series, our host Dr. ...
Carbon Dioxide Removal: Forests
Planting trees has become a bit of a cliché in the fight against climate change, with ubiquitous photos of presidents and CEOs planting a tree to show they’re serious about climate. But, how much impact ...
Building stars on Earth: the potential of nuclear fusion
Energy from nuclear fusion has the potential to cleanly and safely power the world. But, when do fusion experts expect this to happen? What technical challenges must be overcome before we can power our home...
Clean Fuel: Jet Fuel
Aviation is responsible for 2.5% of global greenhouse gas emissions, though this figure is expected to grow as developing parts of the world become wealthier and increase demand for air travel. Experts have loo...
There is a rapidly growing body of research on the progress of climate change, negative emissions technologies, the economics of climate change and the energy transition, policy levers, and other topics relevant to charting a course toward a negative carbon future. Our Research video series distills and explains the latest research that our audiences should be aware of and understand, and features leading scientists, economists, and policy experts.
In this series, we explore different ways to decarbonize transportation, energy, industry, and agriculture. Videos feature subject matter experts who help us explain technical function, costs, scalability, and other pros-and-cons to different technologies and policies that can help us decarbonize.
Mini Explainer Series
These videos are short, less-than-2-minute explainer videos on important concepts and definitions relating to climate.
In this mini explainer video, we break down the term CO2-equivalent, and how it is used to compare different greenhouse gases that have different warming potentials and remain in the atmosphere for vastly different periods of time.
Three energy transition scenarios with Doyne Farmer
Dr. Doyne Farmer, Director of the Complexity Economics program at the Oxford Martin School, and co-author of the recent working paper, Empirically grounded technology forecasts and the energy transition, sat do...
Global shipping industry emissions
How big of a climate problem is the shipping industry? If the international shipping sector were a country, it would be the sixth largest emitting nation in the world. Every year, 11 billion tons of goods ̵...
How much carbon do soils hold?
Soil holds 2x more carbon than vegetation and the atmosphere combined, according to Dr. Asmeret Asefaw Berhe, Professor of Soil Biogeochemistry and Falasco Chair in Earth Sciences at the Department of Life and ...
Scope 1, 2, and 3 Emissions
Companies assessing their greenhouse gas emissions will need to analyze their Scope 1, Scope 2, and Scope 3 emissions. This Climate Now mini provides a brief explanation of what that means. ...
