Fossil Fuels: The Greenest Energy

Fossil Fuels: The Greenest Energy

What if I told you that someone had developed an energy source that could help us solve our biggest environmental challenges, purify our water and air, make our cities and homes more sanitary, and keep us safe from potential catastrophic climate change? What if I also told you that this energy source was cheap, plentiful, …

How does climate change affect biodiversity?

How does climate change affect biodiversity?

(gentle music) – [Instructor] What are some of the global threats so biodiversity? First, I want to emphasize that virtually everything we do locally has global consequences. When we talk about something like a greenhouse gas or a pollutant, that’s something we produce locally from our car or from other things that make up so …

UQx DENIAL101x 3.3.2.1 Increasing greenhouse effect

Today, we’re going to step back in time and look at history’s first ever global warming myth. It’s a myth about the greenhouse effect. In this day and age, we measure the greenhouse effect getting stronger by using modern instruments, aircraft and satellites. But in 1900, when this myth was born, scientists didn’t have these …

UQx DENIAL101x 3.3.5.1 From the experts: Greenhouse effect

Oreskes: It’s simple. It’s basic physics and chemistry. It’s physics and chemistry that we have known since the 19th century Carbon dioxide’s a greenhouse gas. That means that it’s relatively transparent to visible light but relatively opaque to infrared or make it even simpler: light comes in heat gets trapped so if you put more …

UQx DENIAL101x 3.3.1.1 The greenhouse effect

They say it all started with a Big Bang, and white noise on an old TV helps to show that. That white noise reaches us in the same way that the heat causing global warming does. This heat comes from the greenhouse effect. What do the Big Bang and the greenhouse effect have in common? …

UQx Denial101x Winnifred Louis Full Interview

I’m Winnifred Louis, I’m a social psychologist at the University of Queensland. I study identity and decision making. So I started off looking at prejudice and conflict, English-French conflict, gender relations, and I got into the environmental research, in part because I became more and more interested in environmental politics myself. I was inspired by …

The Green New Deal, explained

The Green New Deal, explained

Every few years, they gather to tell us what’s happening to our warming planet. In 2018, they had some news. “It’s very clear that half a degree matters.” This is a chart of how much the global temperature has gone up since we discovered fossil fuels. For a long time, scientists said that we should …

Climate Change: What Do Scientists Say?

Climate Change: What Do Scientists Say?

I’m an atmospheric physicist. I’ve published more than 200 scientific papers. For 30 years I taught at MIT, during which time the climate has changed remarkably little. But the cry of “global warming” has grown ever more shrill. In fact, it seems that the less the climate changes, the louder the voices of the climate …

Are Electric Cars Really Green?

Are Electric Cars Really Green?

Do electric cars really help the environment? President Obama thinks so. So does Leonardo DiCaprio. And many others. The argument goes like this: Regular cars run on gasoline, a fossil fuel that pumps CO2 straight out of the tailpipe and into the atmosphere. Electric cars run on electricity. They don’t burn any gasoline at all. …
