Is the END near?The worsening of CLIMATE CHANGE
![Page 2: Is the end near](https://reader036.fdocuments.us/reader036/viewer/2022062522/58d1ac591a28ab6f6b8b6787/html5/thumbnails/2.jpg)
What is CLIMATE CHANGE?
• Climate change occurs when long-term weather patterns are altered — for example, through human activity. Global warming is one measure of climate change, and is a rise in the average global temperature.
BUT IS IT HAPPENING? REALLY
HAPPENING?

EVIDENCES OF CLIMATE CHANGE
• RISING OF SEA LEVEL• GLOBAL TEMPERATURE RISE• WARMING OCEAN• SHRINKING ICE SHEETS• DECLINING ARCTIC SEA ICE• GLACIAL RETREAT• EXTREME EVENTS• OCEAN ACIDIFICATION• DECEREASED SNOW COVER

Carbon Dioxide• Carbon dioxide (CO2) is an important
heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. Current CO2 Level:
405.92 ppm

GLOBAL TEMPERATURE• This graph illustrates the change in
global surface temperature relative to 1951-1980 average temperatures. The 10 warmest years in the 136-year record all have occurred since 2000, with the exception of 1998. The year 2016 ranks as the warmest on record.
Latest Annual Averrage:
0.99 °C

ARCTIC SEA ICE MINIMUM
• Arctic sea ice reaches its minimum each September. September Arctic sea ice is now declining at a rate of 13.3 percent per decade, relative to the 1981 to 2010 average. This graph shows the average monthly Arctic sea ice extent in September since 1979, derived from satellite observations.

LAND ICE• Data from NASA's GRACE satellites
show that the land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica has been losing about 118 gigatonnes of ice per year since 2002, while the Greenland ice sheet has been losing an estimated 281 gigatonnes per year.

SEA LEVEL• Sea level rise is caused primarily by
two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms. The first chart tracks the change in sea level since 1993 as observed by satellites.Sea Level Latest Measurement:
82.7mm

Climate Change: What Happens after 2100?
Would it be too coldWill our world end?
Is earth still habitable?
Will this world would be flaming hot?
Do you think nothing would change?
Do you think nothing would change?
Would the ocean be still full of fish?
Can we still call Earth as Earth?
Do we even care?Do humans still exist?
