We need to save the Earth. Carbon dioxide is higher than ever in this millennia. In 1950, carbon dioxide was much lower than today. Since the last ice age ended 11,700 years ago, it marked the beginning of the modern era. Humans are causing the warming part. Evidence of warming: Since the late 19th century, (1890) the average temperature has risen by 2.12 degrees Fahrenheit. (1.18 degrees Celsius) But this is all happening fast: In the past 40 years, most of the warming has occured. 2016 and 2020 are tied for warmest years. The ocean has absorbed most of the heat, with the top 328 feet (100 meters) warming 0.6+ degrees Fahrenheit. (0.33+ degrees Celsius) The Greenland and Antarctic ice sheets are melting. Greenland loses and average of 279B tons per year, while Antarctica loses 148B tons. Glaciers around the world are retreating. The amount of snow has decreased over the past 5 decades. And snow is melting earlier. The global sea level rose 8 in (20 cm) but the rate in the last 2 decades has doubled. The Arctic sea ice has been declining rapidly over the last few decades. The number of high temperature events has been increasing in the USA while the record low temperature events has been decreasing. They also reported increased rainfall. The acidity of oceans has been rising by 30%.
That's all, and KidzSearch, please don't take down my question, I've worked really hard on it.
