 Before the start of the presentation, please take
a look of these pictures, that we might seem to
be impossible to happen!
THEN YOU MIGHT START
OVER TO THINK CLIMATE
CHANGE IN ANOTHER
WAY!!!

 You might think,well...nice photography, but it's not
related to me. BUT, you are wrong, the effects of rising
global temporature could not be ignored by anyone.
 Let's look at the latest data the scientist have found over
the past thirty year
 And let the data tells you why!!!!

 "Three degrees of warming increases the risk of strong sea level
rise from, for example Antarctica, or the collapse of marine
ecosystems, such as Arctic sea ice or coral reefs … [It] increases
the risk of intensification of extreme events ... In short, beyond two
degrees of warming we are leaving the world as we know it."
 In the IPCC's most extreme scenario, RCP8.5, global temperature
reaches more than four degrees above pre-industrial levels by
2100. And unless emissions cease altogether, temperatures will
continue to rise long past the end of the century.
 With emissions accelerating faster than they are now for the next
few decades, global temperature rise in RCP8.5 reaches five
degrees by about 2120 and six degrees by 2150. This is a worst-
case scenario, says Levermann, but that doesn't mean it's not a
possibility.

 In 2011, Dr. Peter Höppe, Head of the Geo Risks Research
Department at Munich Re explained what had persuaded him of the
causal link:
 For me the most convincing piece of evidence that global
warming has been contributing already to more and more
intense weather related natural catastrophes is the fact that
while we find a steep increase in the number of loss relevant
weather events (about tripling in the last 30 years) we only find
a slight increase in geophysical (earthquake, volcano, tsunami)
events, which should not be affected by global warming. If the
whole trend we find in weather related disaster should be
caused by reporting bias, or socio-demographic or economic
developments we would expect to find it similarly for the
geophysical events.
