Could Snowpiercer actually happen? |
Not accidentally—there would need to be deliberate efforts over many generations to get an ice-covered Earth. But geoengineering to reduce the risks of climate change does pose other risks that are much more probable than the ones shown in Snowpiercer

Do we have the technology to go carbon neutral today? |
We still need new breakthroughs to decarbonize many parts of our modern economy, especially if we don’t want to drive up the price of energy and goods. But we can make real progress with today’s technology, and invest in good ideas for the next generation of low-carbon solutions. |

Does the concrete needed to build renewable energy negate the good? |
It takes fossil fuels to build renewable energy infrastructure such as solar panels and wind turbines. But those emissions pale in comparison to the CO2 avoided by using renewable energy. |

How are countries held accountable under the Paris Agreement? |
The short answer is that there is no hard enforcement in the Paris Agreement. But all the members regularly meet, share progress, and renew their pledges of climate action, encouraging every country to step up its commitments. |

How are gases in the atmosphere analyzed and measured? |
By shining different kinds of light and radiation through air samples, scientists can tell which gases are absorbing or reacting to that light, and in what amounts. |

How can carbon emissions from freight be reduced? |
Although most of the world’s cargo moves by ship, focusing on land may be the best way to reduce the carbon footprint of freight. |
