Turn Down the Heat: Why a 4°C Warmer World Must be Avoided

Final ProjectPresented by: Hymns Chu

Before the start of the presentation, please take

a look of these pictures, that we might seem to b

e impossible to happen!

THEN YOU MIGHT START

OVER TO THINK CLIMATE

CHANGE IN ANOTHER WA

Y!!!

You might think,well...nice photography, but it's not relate

d to me. BUT, you are wrong, the effects of rising global t

emporature 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.
