How high will it go?

Most predictions say the warming of the planet will continue and is likely to accelerate, causing the oceans to keep rising. This means hundreds of coastal cities face flooding. But forecasting how much and how soon seas will rise remains an area of ongoing research.

By 2033, rising sea levels will flood 4,000 miles of fiber optic cables that deliver the internet and telephone services. Relocating the cables would be expensive and only buy a little time. At first, Alexandria and Nile Delta region would be affected the most. Over time, everyone will be impacted by a disruption in these services.By 2038, most Egyptian coastal cities and towns will be “chronically inundated” according to the Egyptian knowledge bank. They will see 10% of their area flooded at least twice a month. By 2100, more than half of the communities along the the whole country will experience it.By 2045, another study found that 300,000 coastal properties will be flooded 26 times a year. The value of that real estate is $136 billion. By 2100, that number will rise to $1 trillion. At most risk are homes in Alexandria and Nile Delta area. For example, Nile Delta region would experience $billion in property damage by a four-foot rise in sea levels. It would also put the headquarters of Facebook and Yahoo underwater.The Intergovernmental Panel on Climate Change predicted sea levels will rise between one and two feet by 2100. That's 52 cm to 98 cm. The IPCC made this forecast in 2007. A two-foot rise would flood tens of millions of people living in low-lying areas. It would swamp many Egyptian cities.
