Spotted lanternflies, Japanese barberry, Oriental bittersweet – When plants and animals like these invade our environment, they can disrupt other organisms that are native to the region. But can we stop these species? And should we?
What’s the climate impact of building wind turbines?
Even though wind turbines offer emission-free energy, manufacturing, transporting and installing those turbines does create greenhouse gases. This week on Possibly we do the math and find that turbines deliver emission savings in less than a year.
Heat pumps run on a substance that can create a lot of emissions. Is it still worth buying them?
If refrigerant, the key substance inside a heat pump leaks into the atmosphere, it can warm the planet thousands of times more than CO2. The Possibly team does the math to see if that risk outweighs the climate benefit of heat pumps.
