Greenland and Arctic warming is causing poorer air quality. Burning fossil fuels increases greenhouse gases that trap heat and raise temperatures, melting more ice. This exposes darker surfaces that absorb more heat in a feedback loop. More melted freshwater flows into oceans, changing circulation patterns and affecting air pollutant transport. Warmer conditions increase cloud coverage and ozone formation, worsening air quality. To improve conditions, alternative energy sources need to replace fossil fuels to reduce carbon emissions and warming trends.
Are ‘little ice ages’ and ‘megadroughts’ possible?
Scientists are investigating whether changes in ocean circu- lation may have played a role in causing or amplifying the “Little Ice Age” between 1300 and 1850. This period of abruptly shift- ing climate regimes and more severe winters had profound agri- cultural, economic, and political impacts in Europe and North America and changed the course of history.

CSCR Agriculture Track w/ Larry Klotz: Weather or Not - Effects of Changing W...Sustainable Tompkins
Climate Smart & Climate Ready Conference Agriculture Track on April 19, 2013 at NYS Grange in Cortland, NY. Prof. Larry Klotz, SUNY Cortland. Weather or Not: Effects of Changing Weather on Local Agriculture. What is climate change? What are regional implications?
Conclusions
Ocean Mixed Layer Temperatures for both models are very similar, showing that the ocean conditions for the LGM and future climate underwent the same conditions at some point, could lead to colder temperatures
With this data alone available, we must infer that there could be a climate change due to melting of ice into the ocean, until there is more data to back up the hypothesis
EdGCM limits the amount of information we can compare
○ Only 100 years of predicted models
○ Not as many parameters available to model

The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions
Social climate change & water crisisIan Mohammed
this z a ppt on climate change and water crisis
well, I would actually say that a few slides in da climate change r frm other ppt's bt most dem were searched by myself.
in da water crisis also I hv done da same....
for more info;s I hv also made a page of IMPORTANT references..
thank u
hope u'd lyk it
comment below
It explains about how climatic changes are inducing natural disaster. It contains a series of climatic changes, which ultimately results in disasters. Enjoy the facts and info.

3. What is causing warming in Greenland and the
Artic?
• There are natural causes:
• Uneven heating of solar radiation
• Storms and changes in air pressure cycling heat through the latitudes to the poles
• However, most importantly, there are anthropogenic causes which have more severe consequences:
• Burning of fossil fuels increasing extra greenhouse gases into the atmosphere
• From increased temperatures, will increase cloud cover and formation of pollutants as ozone and increase the rate of
formation of natural ozone pollutants
• Increased melting of polar ice sheets
• Sea levels increase due to freshwater addition to the oceans
• Changing of albedo on the surfaces

4. Changes in Greenland’s ice sheet
• Greenland ice sheet is covered by 85% ice, the
rest of the surface is melted liquid water pushing
the ice sheet 1000 feet below sea level
• If the entire Greenland ice sheet would melt,
would increase the global ocean levels by 23 feet
• Increased ocean levels would change
atmosphere circulation patterns
• Affecting air pollutant travel

5. Increased heat from burning of fossil fuels…
• The largest source of energy in the US and used in other parts of the world
• Combustion releases carbons into the air more frequently than natural
causes
• Changing the natural carbon cycle and the amount of heat transferred to
the polar regions due to more heat trapped inside the atmosphere
02 Dec 14 5
7. …then increases the greenhouse gas
concentrations in the atmosphere…
• From the increased greenhouse gases, ice forms later in the year and melt sooner
in the year, so a smaller net amount of ice in the polar regions
• Affect wildlife dependent on the polar regions
• Could increase forest fires in other regions
• The melted freshwater flows into the oceans, increasing level and changing the
circulation of ocean currents, affecting the natural flow of heat
• The albedo becomes lower in the polar ice caps causing a positive feedback loop
02 Dec 14 7
8. …thus creating poorer air quality circulation…
• The air pollutants that travel across the US will be taken further and in different
locations from changes in weather patterns from changes in temperature and air
pressure in the atmosphere
• The permanent High pressure Zone in the Atlantic could be affected and possibly
move and not be present, causing the jet stream to flow in abnormal paths and
become more wavy
• Changes in temperature can cause increased cloud coverage which could increase
production of pollutants as ozone and increased circulation of pollutants and force
air pollutants into areas normally with lower pollution levels

9. Suggestions and conclusions
• Change our main energy sources to renewable
• Decrease transportation carbon emissions by changing fuel type, electric
cars or use a different engine types as the fuel cell which uses hydrogen
