📈Numbers of floods could quadruple as the gravitational effects of the lunar cycle combine with climate change to produce "a decade of dramatic increases" in water disasters. Coastal cities would experience "rapidly increasing high-tide floods" lasting a month or longer

🌕The main cause is a "regular wobble" in the moon’s orbit - first recorded in 1728 "What’s new is how one of the wobble’s effects on the moon’s gravitational pull – the main cause of Earth’s tides – will combine with rising sea levels resulting from the planet’s warming"

The wobble in the moon's orbit takes 18.6 years to complete. 🌊For half of that time, regular daily tides on Earth are suppressed, meaning high tides are lower than normal, and low tides are higher than normal

The next "lunar assist" to high tides will be around mid-2030. By that time global sea levels will have been rising for another decade. It will have passed a "tipping point" and the result will be a "leap in flood numbers on almost all US mainland coastlines" said

According to the UN - by 2050 coastal cities will see hundreds of millions of people at risk from floods made worse by rising seas. The leader of 's Sea Level Change Team, said urban planners should prepare for the increase in high-tide floods and extreme weather events
