answer:Yes, global warming is real. Humans burn tons and tons of fuel, especially since the Industrial Revolution, that release greenhouse gases into the atmosphere. These gases trap heat on Earth, raising temperatures. The temperature increase has been measured and directly correlates to human activity. You’ve probably heard that Earth goes through climate cycles, which is true (it’s been much hotter—and colder—in the past). The problem with global warming is not necessarily that the earth is getting hotter; it’s the speed at which temperatures are increasing. It is very difficult for species—including the human species—to adapt to sudden changes. Global warming is not going to threaten human civilization. Rich westerners with internet access will survive. The people who will be harmed the most are poor people in coastal or marginal areas who will need to become migrants to survive. What can we do to stop global warming? As an individual, use less energy—try to drive less, use energy efficient lights, etc. But really, what needs to happen is comprehensive policy that taxes fossil fuels and invests in cleaner, renewable energy. And even then, a lot of damage has already been done. The best we can hope for is to slow down the changes that are already taken place. I also think we ought to support the impoverished people that global warming will displace and/or make miserable.
