Climate change
It gets way too cold each year. Luckily, the Earth’s atmosphere traps incoming heat from the sun, and this slowly makes the Earth warmer. This is called climate change or global warming. Greenhouse gases help the atmosphere trap more heat, so humans since the late 1700s have been hard at work to emit as many of them as possible. With our combined efforts, we have managed to make great progress, increasing global air temperature as much as 1,5 degrees centigrade. You may help by grilling a lot of meat and other animal products, having your radiator and air conditioning on and on their maximum setting at all times, and burning down the entire Amazon rainforest.
