This weekend, the Southwest region of the United States is expected to experience extreme temperatures, with some areas reaching up to 130 degrees Fahrenheit. This heat wave is the latest in a series of extreme weather events linked to climate change, caused by El Niño and the world's hottest period in the last 125,000 years. Governments and citizens must take action to reduce emissions and mitigate the effects of climate change in order to address the urgent need to combat climate change.
