TIL about planting trees

In our last episode, we talked about using technology to suck out extra carbon dioxide from the atmosphere. But you might also be thinking—don’t trees do that? Yeah, they do!... more

We’ve had people ask us, if climate change is caused by adding too much CO2 into the atmosphere, can’t we just suck it back out? Won’t that solve our climate... more

TIL about national security

Is climate change really a national security issue, in the same way we think about terrorism or nuclear weapons? And if so, what are our governments doing about it? In... more

TIL about sea level rise, part 2

Sea level rise is already happening and affecting people right now. We invited Prof. James Renwick back to TILclimate to talk about the near future: what will sea-level rise look... more

TIL about sea level rise, part 1

If you’ve heard only one thing about climate change, it might be that sea levels are rising, and many of the Earth’s islands and coastlines are at risk. But, why?... more

Surveys show that both left- and right-leaning Americans support policies that slow climate change. So why aren’t we seeing more of these policies pass as legislation? In this episode of... more

TIL about fusion energy

Let’s talk about a technology that could change our whole energy system, but so far hasn’t generated a single watt. In the season finale of TILclimate (Today I Learned Climate),... more

07/16/2020 | 12 MINS

TIL about carbon capture

This season, we’ve talked about alternative energy sources that don’t emit carbon dioxide -- but what if there was a way to continue using fossil fuels for energy without emitting... more

06/18/2020 | 15 MINS

TIL about nuclear energy

We know how to generate tons of electricity without pumping greenhouse gases in the atmosphere, using a technology that’s already mature, widespread, and competitive with fossil fuels -- and also,... more

05/07/2020 | 11 MINS

TIL about energy efficiency

We hear a lot about technologies that produce carbon-free energy, but what about actually using less energy to begin with? In this episode of TILclimate (Today I Learned Climate), Harvey... more

04/02/2020 | 11 MINS

TIL about wind and solar

What will it take to generate the electricity our society needs, without generating carbon emissions? In this episode of TILclimate (Today I Learned Climate), Dr. Magdalena Klemun at the MIT... more

Is it energy or electricity?

In this mini-episode of TILclimate (Today I Learned: Climate), host Laur Hesse Fisher breaks down what we’re actually talking about when we use the word “energy”. In a few minutes,... more

02/06/2020 | 10 MINS

TIL about fossil fuels

Fossil fuels -- coal, natural gas, and oil -- provide the large majority of our power in the United States and around the world. In this episode of TILclimate (Today... more
