7 American cities that could disappear by 2100

No city in the world will be immune to the effects of a warming world, some are more vulnerable than others though.

Let’s consider rising sea levels threaten to submerge entire cities by 2100 due their location in low lying coastal areas. If the worst projections are true American cities like Miami and New Orleans will be underwater.

Conservative estimates show cities around the world could witness 6 ft of flooding by 2100.The National Oceanic and Atmospheric Administration has predicted a sea level rise of 10-12 ft if global emissions continue apace.

It is possible that some cities will install new infrastructure and artificial barriers for protection, but time is running out.

Here are the 7 cities in the USA most likely to disappear underwater by 2100…

  1. New Orleans, Louisiana is already sinking.
  2. Miami, Florida. Sea levels there are rising faster than those in other areas of the world.
  3. Houston, Texas could be innundated by another storm like Hurricane Harvey
  4. Atlantic city, New Jersey was mostly underwater during Hurricane Sandy, but the next disaster could be worse.
  5. Charleston, South Carolina could be underwater by 2100
  6. Boston, Mass. 1 in 6 homes could face regular flooding by the turn of the century.
  7. Virginia Beach, Virginia is witnessing one of the fastest rates of sea level rise on the East coast.

The Titanic…today.

For the first time in 14 yrs researchers have taken a look at the Titanic.

Check out the video and see what is new about the wreck.

Climate change and the effect on the world’s waves

New research shows that a warming planet will alter ocean waves across 50% of the world’s coastlines. The implication for erosion and coastal flooding srte not good.

As part of the Coordinated Ocean Wave Climate Project, ten research organizations, combined to look at a range of different global wave models in a variety of future global climate models.

Differences were noted , but if the 2degree Paris agreement is kept, changes in wave patterns will stay within a reasonable normal range. The trend is not this..most likely wave patterns will affect 50% of the world’s coastlines in a more adverse manner.

 

The height of waves will grow in some areas and lessen in others. Some areas will see the height remain the same, but their wavelength and frequency will change. More force will be exerted on the coast, and any infrastructure. Wave direction can change how much sand is moved along the coast.

In short our coastlines will be under assault…erosion, flooding, and damage to infrastructure will become more frequent.

Ottawa- Smelly Water Still Drinkable

Compounds released by plants and algae are to blame for the strange smell and taste of tap water in Barrhaven, but the City of Ottawa says there is nothing to be worried about.

 

The city has received a few calls from residents who have noticed a specific taste in their tap water. It is due to seasonal changes in the Ottawa river. The taste or odor is caused by trace levels of natural substances released by aquatic plants and algae..an event that happens every 2 or 3 years, and lasts a few weeks, this years event is made worse by the summer’s high temperatures.

The result is a earthy , grassy smell and taste…especially if the water is warmed up.  The taste of the water is affected , but their is no health risk. The water remains safe to drink.

The last time this happened was August and September 2015.

Mass droughts in Pakistan by 2025 possible.

Pakistan could face an absolute water scarcity level by 2025. The Pakistan Council of research in Water Resources has made this grim forecast, It was reported that Pakistan crossed the water stress line in 1990, crossed the water scarcity line in 2005…next up absolute scarcity in 2025.

An unnamed government official is calling for action to find a solution, but notes there is a lack of government funding.

Pakistan has the fourth highest rate of water use in the world, but is dependent on a single source..the Indus river basin in India. Rainfall has been steadily declining in the area, some blaming climate change.

In Pakistan’s largest city Karachi over the million residents few have running water as the land has gradually dried up, forcing many residents to queue for hours for supplies given to them.

The former head of the Water and Power Development Authority says water policy is simply non existent. Policy makers act like absentee landlords over water. Water has become the property of the landlord , while the poor are deprived of their share.

 

Experts say that population growth and urbanization are the main reasons behind the crisis, compounded by climate change and poor water management.

Pakistan has not built new dams since the 1960’s leading to a lack of water storage facilities in the country. A maximum of 30 days supply is kept on hand.
