The document discusses evidence that climate change is occurring due to human activity, including rising sea levels, higher global temperatures, declining Arctic sea ice, and increasing carbon dioxide levels in the atmosphere. Key data points are presented showing increases in global temperature, CO2 levels, sea level rise, and decreases in Arctic sea ice extent over recent decades. The future impacts of climate change after 2100 are uncertain but could include extreme heat, changes to the oceans and sea life, and Earth may become largely uninhabitable for humans.

1. Is the END near?
The worsening of CLIMATE CHANGE

2. 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?

3. 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

5. 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

7. 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

THE YEARS

9. 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.
Down by 13.3% per decade

11. 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.

13. 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

15. Climate Change: What Happens
after 2100?
Would it be too cold
Will 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?
