Main Cause and Effects of Climate Change in the World
Ice Sheets
(Graph from NASA shows decreasing ice masses in Antarctica)
Antarctica ice sheets currently decrease at a rate of 147 gigatonnes a year.
(Graph from NASA shows decreasing ice mass in Greenland)
Greenland ice sheets currently decrease at a rate of 280 gigatonnes a year.
Could make certain places in Antarctica and Greenland habitable by humans.
Large amounts of melted water from the ice sheets run down into the sea, contributing to the rising levels.
Carbon Dioxide
Greenhouse Gas
(Diagram of the Greenhouse Effect from Newswire.net)
When released, greenhouse gasses trap and hold heat in the atmosphere.
(Graph from NASA showing current CO2 trends)
.
The more Carbon Dioxide there is in the air, the hotter the temperature is.
Released through natural and human activities.
(Burning fossil fuels)
(Volcanic eruptions)
(Respiration)
(Deforestation)
Arctic Ice Minimum
(Graph from NASA showing the amount of Arctic sea ice over the years)
(Picture of Arctic sea ice in 2019)
(Picture of Arctic sea ice in 1979)
Each year in September, Arctic ice reaches a new minimum.
Amount of ice declines at a rate of 12.85% per decade
(Reduces habitats for cold-weather animals such as Polar Bears)
100% of the melted Arctic sea ice contributes to the rising sea levels as it the ice is already floating on the water.
Global Temperature
(Graph from NASA shows that temperatures are at an all time high)
(Global temperature in 1888)
(Global temperature in 2019)
19 of the 20 warmest years ever have all occurred since the year 2001.
High temperatures melt ice in the Arctic.
(Results in hotter, longer summers and warmer winters)
High temperatures reduce the size of large ice sheets.
Sea Levels
(This graph from NASA represents sea levels since 1993 and shows that they are at an all time high)
Sea levels rise at an approximate rate of 3.3 millimeters per year.
Sea levels also rise from the expansion of warmed water.
Areas located near large bodies of water are flooding more often.
