CLIMATE CHANGE !
IS WEATHER BECOMING MORE EXTREME?!
A. ARE MAJOR STORMS (SUCH AS HURRICANES)
BECOMING MORE FREQUENT AND/OR MORE
INTENSE?
B. ARE THERE MORE EPISODES OF DROUGHTS AND
FLOODING AROUND THE WORLD THAN THERE WERE
IN THE PAST?
C. ARE TEMPERATURE EXTREMES GREATER THAN THEY
HAVE BEEN HISTORICALLY?
JP and Ryland
a. Are major storms (such as
hurricanes) becoming more frequent
and/or more intense?

Yes they were pretty frequent

But not as frequent now

One of the big factors of them is the climate change

In some places a climate change can trigger a hurricane

They have not been as frequent around 2013
Here is a graph of them from 19252007

During 1948 they were not very frequent

As well as 2001 they occurred a bit more

But in 2007 they started to pickup
They were very frequent

As seen in the last slide they are more
frequent

They were very uncommon during 19481957

And became very frequent from2001-2007

But around 2013 they started to stop

This graph is from 1880-2013

And it is clear there have been way less
b. Are there more episodes of droughts
and flooding around the world than
there were in the past?

Yes they are slowly becoming more frequent in the current day

Both droughts

And flooding's

They are both slowly stating to not become as frequent
Here is a graph of flooding's

They are still common but not as common
as they were before

There were a bunch of flooding's in 2011
and 2012

And dropped off around 2013

They have also not been very frequent
Flooding's in 2015

Recently in Queensland a major
flood happened

An 8 year old boy and 2 adults
were killed in it

The wild weather caused by a low
pressure system moves south to
coincide with peak hour traffic

And luckily not too many people
were harmed
2 Flooding in January

January 16 2015 135,000people
had ben affected in Malawi,
Mozambique and Zimbabwe

While in Madagascar weeks of the
high rainfall already made it
perfect for a flood

The flood had caused damage to
not only crops but also livestock

With high river levels and soil
saturation. The flood happened

Zimbabwe had the flood go
across their country

And at least 14 people died from
the flooding

And that affected 500 households
that became in need of urgent
assistance

With multiple neighborhoods
being evacuated
Here is a graph of droughts from
2000-2009

This graph shows droughts from
2000-2009

They have slowly become less
frequent
The U.S.A is supposed to face their
worst drought in1,000 years

As seen in the picture on the left
the risk of droughts in 2050-2099
are insanely high

California is already on their 4th
year of drought

And projected droughts are to be
far worse than California's

But the predicted ones are
projected to last for decades not
years

And with the demand for water
have drastically reduced the
ground water source
Conclusion

Droughts are slowly becoming more
frequent than they were

As well as flooding's they have almost
stopped and don’t occur as much as
they used to. But have occurred recently

So in conclusion floods are slowly coming
back. And droughts are projected to be
back in the U.S.A around 2050

But maybe next year or in a few years
they could become frequent again

And if there is a drought it is exceptional
(As seen in photo)
c. Are temperature extremes greater
than they have been historically?
Now the temperature is greater than before. Here is four examples.
First:
Population
Second:
carbon dioxide, methane, and
nitrous oxide
Third:
ice cores , and most recently from
the Mauna Loa station.
First
Global population. Look at the graph, at first 1300, population was
lower than one million but now,,, over than 7million.
Second
from the 2013 US national climate assessment shows two
thousand years of atmospheric concentrations for carbon
dioxide, methane, and nitrous oxide: for 0~1800years Carbon
Dioxide was not that much high. But only for 500 years Carbon
Dioxide jumped up. It means global warming is getting worse and
Third
shows over 10,000 years of carbon dioxide concentrations
with measurements taken from ice cores , and most
recently from the Mauna Loa station.
