- in australia and western pacific high pressure cells in the atmosphere bring drought conditions and rise in the frequency and intensity of bushfires
- el nino events have become more frequent and intense since the mid 1970s --> consequence of rising temperatures

There is more low pressure areas of rising air in the East Pacific rather than the West and there is high pressure areas of rising air in West Pacific rather than East. 
climate change leads to rising temperatures and then more water vapour due to increase in evaporation. Water vapour changes circulatory patterns in atmosphere while redirecting moist air ]]> 2020-06-23 03:42:36 UTC https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636917524 rekw21 https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636917542 - El nino events have become more frequent, persistent and intense since the mid 1970’s as a result of rising temperatures. 

- El Nino is the event of warm moving water moving from the Antarctic Northwards along the western coast of South America weakens, allowing the water temperature to rise through the Western Pacific. 
- Consequently low pressure areas of high rising air over the  the Easter  Pacific and falling are in the Western Pacific

- Under El nino conditions, warm ocean currents along Peru’s coast

Unusual warming of surface waters in the eastern equatorial pacific ocean -> can suppress the thermocline (level of ocean depth that separates warm surface water from the colder water below) 

Impacts trade winds and atmospheric conditions

Occurs every two to seven years

The effect is becoming magnified by climate change e.g: California El Niño brings cool temperatures with rain and  La Niña brings heat and dry weather.

 Future El Niños will make flooding more likely while future La Niñas will bring more drought and intensified wildfire seasons.

Strong El Niños can cause severe drought in dry climates such as Australia and India, intense flooding in wetter climates such as the Pacific Northwest and Peru, and causes more hurricanes to form in the Pacific and fewer in the Atlantic.

Climate change is increasing the frequency of extreme El Niño events, leading to intensifying droughts, worsening floods, and shifting hurricane patterns

El Nino is actually intensified in warmer climates, and climate change is doing exactly that. 

Strong El Niños can cause severe drought in dry climates such as Australia and India, intense flooding in wetter climates such as the Pacific Northwest and Peru, and causes more hurricanes to form in the Pacific and fewer in the Atlantic, and climate change is making these events more intense.

These regions tend to be warmer than usual. La Nina occurs as the counterpart - these regions tend to be colder.

Changing circulation patters in the atmosphere have redirected moist air away from the semi-arid area, resulting in more frequent and more intense drought. It is most intense in Australia and Europe - there are heat waves and high temperature]]> 2020-06-23 03:43:10 UTC https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636917908 https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636918058 - Warm ocean currents along peru force fish to move to colder waters

This will impact agricultural such as rice crops and shrimp farms.

- salt intrusion in freshwater stores which puts pressure on freshwater demand 
- rice crops aren't able to grow due to salty water, they are forced to farm shrimps

- the inhabitants have a direct impact of the rising sea levels and and extreme weather events like cyclones
- the erosion is destroying and washing away their homes and land
- due to this and the intrusion of saltwater, many people have had to adapt by making saltwater resistant rice or have started farming shrimp
- the groundwater is starting to be as salty as the ocean which causes inadequate water quality
- many climate migrants, will hit the millions]]> 2020-06-23 03:49:13 UTC https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636921570 https://padlet.com/list4/srp1ofy6rtdn5p45/wish/636921604

High risk of sea level rise and extreme weather such as cyclones

Predictions that it may be permanently underwater 

Only minimal soil as a barrier on river banks

Risk of damage to their crops and agriculture as well as homes

Only available drinking water is salt water = health risks for the people drinking the water as well as rice crops unable to survive

• Washing away peoples’ homes 
• By the end of the century, the entire area will be underwater 
• Limited drinking water as not all is safe to drink, it is still quite salty -> impacts not only people but crops too -> too salty for shrimp 
• Saltwater intrusion 
• Bangladesh’s prime minister Sheikh Hasina has told the UN that a one-metre rise in sea level – a plausible scenario this century – would submerge a fifth of the country and turn 30 million people into “climate migrants”
• Illegal migrants: Up to 20 million Bangladeshis are said to be living illegally in neighbouring India.
• climate impacts may even prevent people moving, he adds, as they become too poor to make the leap
• The population of Dhaka has roughly doubled in 20 years to 19 million -> overpopulation
• Impact on other countries: A large number of people are moving to Malaysia, India, Pakistan and the Middle East. -> resource scarcity
