Transforming Air Into Pure Drinking Water Is Finally Possible, Here’s How

Deserts are not particularly welcoming environments, and yet at least hundred million people live in desert regions around the world, according to the UN. They have to make due with less than 25 cm of rainfall each year, and for many, even that miniscule water supply is under threat as climate change is making dry […]

Space Mirrors and Other Weird Ways to Fight Climate Change

Today on Reactions: craziest ideas to combat climate change. Let’s do this. First up: massive gigantic enormous space mirrors. The Sun is constantly emitting all kinds of light — including visible, ultraviolet, and infrared— which heat up the Earth. A space mirror is designed to cast a small shade on the Earth and reduce the […]

Nuclear Power Was Supposed to Solve Climate Change… What Happened? | Hot Mess 🌎

Thanks to the funders of Peril and Promise for supporting PBS Digital Studios. Since the 1950s the world has had a carbon-free, weather-independent energy source. It works with our existing grid and infrastructure, and it isn’t dependent on batteries or back-up power from fossil fuels. If the goal is to slow down climate change, shouldn’t […]

Australian Nuclear Responsibilities – Ben Heard

I want to tell you a little bit about the current situation with nuclear technology here in Australia. The first thing to tell you is that Australia prohibits the use of nuclear energy. Under section 140A of our Environmental Protection and Biodiversity Conservation Act, a minister must not approve one of several things, all of […]

Nuclear Power Plants Are Floating on Water…Wait What?

– Nuclear power is one option to free humanity from our dependence on fossil fuels for energy. Unlike oil, coal, or gas, generating nuclear power emits no CO2. Though, it must be said that it does create radioactive waste, some of which has to be stored securely for thousands of years. And unlike wind or […]

Using Space Mirrors to Cool the Globe | Hot Mess 🌎

Humans are running a dangerous experiment on our planet. We’re putting more and more carbon dioxide and other gases into the atmosphere, which are trapping the sun’s energy, and lo and behold, our planet is heating up in response. To fix this, we could cut carbon dioxide emissions, but that’s been hard. What if there […]

Your Climate Change Conscience – feat. Al Gore

[PBS Bumper] [Intro] You know what’s fun? Puppies. Waterslides. Puppies on waterslides. You know what isn’t fun? Thinking about the climate change induced end of the world. And being told it’s your fault. And that the problem is so massive it’ll take all of humanity working together to avoid the collapse of basically everything we […]

Plants vs Solar Panels: Which is better at capturing solar energy? | We The Curious

This is an aquatic plant called pondweed, and we can see that it’s making tiny bubbles of gas. This gas is oxygen and all plants produce it in a process called photosynthesis. The word photosynthesis comes from the Greek meaning ‘light’ and ‘putting together’. Plants use the energy in sunlight to make sugars, out of […]

Cosmic Journeys – Earth in 1000 Years

Ice in its varied forms covers as much as 16% of Earth’s surface, including 33% of land areas at the height of the northern winter. Glaciers, sea ice, permafrost, ice sheets and snow play an important role in Earth’s climate. They reflect energy back to space, shape ocean currents, and spawn weather patterns. But there […]

Could Everyone Have Solar Power? | Hot Mess 🌎

Look around at houses these days and something might jump out – there’s a lot of shiny roofs! By the end of 2016 in the U.S., over 1 million homes had solar panels, with four times as many installed that year compared to just four years earlier. But if you don’t own the roof over […]
