Supporting details: A hotter atmosphere causes earth's snowpacks, glaciers to meltdown, and this will cause abnormal sea level rise. The sea-level rise is very dangerous because it makes it easier for floods to happen. Furthermore, the oceans are getting hotter, increasing, and growing more acidic. The oceans are getting hotter since they consume 90 percent of the excess heat in the climate. This variation causes the oceans to expand, according to higher sea levels. Lastly, due to climate change, the weather is getting more extreme. Heatwaves are more common global increasing severe weather situations, such as hurricanes.
