So is the grass really greener on the other side? Think about your bathtub at home. My company has developed a technology called direct air capture that removes CO2 using large fans to pull air through a filter that has a liquid capture chemical flowing over it. Overgrazing those lands can degrade soil health and biodiversity. Affirming shared values reduces the feeling of being attacked; being argumentative rarely succeeds. If they are willing to acknowledge even a small chance that climate change is real, don’t they want to be on the right side of the argument? But, as you’ve probably discovered, facts don’t always help people see the reality. People who don’t see climate change can be frustrating because the scientific facts are so clear. Or that you can also engage in politics, and work with others for climate justice and sustainability. And there’s no greater need than stopping climate breakdown. Second, and perhaps more importantly, I believe that laughter is an excellent way of reaching wider audiences and engaging people who are less interested in the topic. What are young people most worried about? Cows burp and fart methane -> Methane traps heat -> Trapped heat increases Earth’s surface temperature -> Global warming. Because what’s more important – staying out of detention or having a livable planet? Do you eat a plant-rich diet, take short showers, walk, bike, or take public transport to school, buy used clothes, repair broken appliances, hang your clothes to dry, and avoid air travel? This is an amazing change from just a few years ago, and it’s happened because of people like the climate strikers. How climate change will impact cows and the dairy industry. It’s important that we learn to laugh for two reasons. So, what else can you do? If we continue to emit CO2 at the current rate, we are going to see catastrophic consequences. There are also vested interests in maintaining the status quo. So humour can also be used to get the message across. The Arctic ice is melting, places that used to experience brutal, heavy winters now experience mild, chilly winters, while untimely rains, floods, typhoons and cyclones rage around the world. We humans are pretty smart and capable creatures, so I don’t worry that we’ll figure out ways to adapt. You can find carbon calculators on the internet that help you to work out the impact of your behaviours. Reduce your own fossil fuel use. That chemical binds to the CO2, removing it from the air, and then we purify and compress it. Climate striking every Friday is a great start. If we leave it on, eventually the tub will overflow and cause great damage to the house. One cow can produce up to 200kg of methane a year. And humour can be a coping mechanism. Talking about climate change using comedy helps me think about it in a different way, and to communicate in a simpler manner. You are obviously both smart and thoughtful kids, so I will be blunt and tell you that climate change is already causing big changes in our world. Learn about it so you can answer questions. But the negative effect on the climate of Methane is 23 times higher than the effect of CO2. With thanks to Poole high school, Dorset; St Bernard’s high school, Westcliff-on-Sea, Essex; John F Kennedy Catholic school, Hemel Hempstead, Herts, and the Guardian Education Centre. Laughter has a strong social function in bonding groups of people together and also helps make the message more relatable. It can be interesting to do a personal greenhouse gas inventory. 3. • Steve Oldham, CEO of Carbon Engineering, a Canadian-based clean energy company. We need to find ways to survive the grief and the loss of so many things we currently take for granted. Do you think of cows and global warming in the same sentence? Should you make that cheeseburger a double? But we’re talking millions of years. Good question. • Matt Winning’s show, It’s The End Of The World As We Know, is part of the Edinburgh festival fringe. Sharks are rarely seen farting. Friends, family and others are much more willing to help when they realise something is important to someone they love, even when they may disagree about the facts. For example, the environment secretary, Michael Gove, was championing the expansion of Heathrow airport at exactly the same time as apparently agreeing that there’s a climate crisis – in spite of the fact that air travel is one of the fastest-growing sources of greenhouse gas emissions. Besides emitting greenhouse gases, another common criticism of beef production is that cows take up nearly half the land in the United States. Scientists have published a surprising amount of work relating to animal farts and our climate. • Dani Rabaiotti, environmental scientist and co-author of True or Poo?, Quercus, £8.99. An ecologist has said that ‘mob-grazing’ cows could reverse climate change. I know this because I’m both a climate researcher and a standup comedian. Comedy makes people more open to new ideas. There are many ways that we contribute to climate change through our daily activities, often without realising it. Here are three things. Let’s fight to keep it that way. A cow does on overage release between 70 and 120 kg of Methane per year. The good news is, there are a number of great minds working on technological solutions – from renewable energy to electric vehicles – to do just that. One of the problems is that most politicians won’t accept that we need a very different economic model, one that recognises that continuous growth isn’t possible on a planet with limited resources. 2. Well, the good news is that nearly all politicians in this country accept that climate change is happening and that it’s caused by human activities; almost all political parties have now accepted that we face a climate emergency. “Drawdown” is the name for the point when emissions peak and then begin to go down on a year-to-year basis. We need to change our idea of what success looks like, so that instead of being obsessed by money, we measure human wellbeing and the health of our natural environment. I do serious science stuff during the day, but then tell jokes about the climate at night. • Jeff Goodell, author of The Water Will Come: Rising Seas, Sinking Cities, And The Remaking Of The Civilized World. Whatever the answer to that is, we must do everything we possibly can sooner than we think we can, and more brilliantly and imaginatively than we think possible. I really like the world we live in, and I’m sure you do, too. You can be very powerful when it comes to action, as -: Greta Thunberg has showned the world the power of ordinary schoolkids.
