San Diego & Key West Experiencing "1/100yr" Floods Monthly. US coastal areas are set to be deluged by far more frequent and severe flooding events if greenhouse gas emissions aren’t slashed, with rare floods becoming the norm for places such as New York City, Seattle and San Diego, new research has found.
The study, undertaken by researchers from Princeton and Rutgers universities, found that along all of the US coastline, the average risk of a 100-year flood will increase 40-fold by 2050. Such floods are statistically expected to occur only once every 100 years because of their severity, although this doesn’t mean these sort of floods never happen in consecutive years. The annual chance of such a flood is around 1%. The research found that if emissions are not curbed, San Francisco and Seattle would both get a 100-year flood every year by 2050, while San Diego would expect 10 such events annually and Key West in Florida would be hit 11 times a year. “Most coastal areas will experience relatively large increases in flooding events,” he said.

US Coastal Flood Events 10x 2015 Frequency. WASHINGTON - U.S.
East and Gulf Coast military installations are at risk of losing land—where vital training and testing grounds, infrastructure and housing now exists—as sea level rise moves the high tide line inland in decades to come, according to a Union of Concerned Scientists (UCS) analysis released today. The analysis, “The US Military on the Front Lines of Rising Seas,” found that coastal installations will experience more extensive tidal flooding and when hurricanes strike, deeper and more extensive storm surge flooding. “We’re now at the front end of the changes that will occur, with some installations already dealing with flooding during extreme high tides,” said Erika Spanger-Siegfried, lead author of the report and senior analyst in the Climate and Energy program at UCS.
The UCS analysis found: Floods Threaten 1.3bn People (& $158tn in assets) By Laurie Goering, Thompson Reuters Foundation Cities around the world are failing to plan for fast-increasing risks from extreme weather and other hazards, particularly as population growth and surging migration put more people in the path of those threats, the World Bank said.
By 2050, 1.3 billion people and $158 trillion in assets will be menaced by worsening river and coastal floods alone, warned a new report from the Global Facility for Disaster Reduction and Recovery (GFDRR), managed by the World Bank. "Cities and coastal areas are woefully unprepared for the kind of climate and disaster risk now facing our world," said John Roome, the World Bank Group’s senior director for climate change.

The government is being warned to prepare for an impending stream of refugees from the Pacific as low-lying atolls are swamped by sea-level rise over the coming decades.
Labour is also calling for the government to take a humanitarian approach to people from the region who are overstayers in New Zealand. United Nations warns if sea level rise continues at the current rate, the Pacific atolls of Kiribati and Tuvalu could be completely submerged within decades.

The people there feared for the future, he said. "We are so afraid and we think about Kiribati, Kiribati maybe in future is going to sink, we worry about it. " Sea Levels 2.5m Above 2015 Levels. High-resolution connectivity maps designed at Clemson University display the potential corridors used by animal populations to move between both large and small areas.Image Credit: Paul Leonard and Edward Duffy / Clemson University CLEMSON, South Carolina — Clemson University scientists Paul Leonard and Rob Baldwin are part of a collaborative study on how rising sea levels and increased urbanization — both now and in the future — are joining forces to fragment habitat connectivity across the region.
Leonard, Baldwin and four other co-authors contributed to the paper, “Landscape Connectivity Losses Due to Sea Level Rise and Land Use Change,” about wildlife habitat connectivity in the Southeast that has been published in the journal Animal Conservation. By the year 2100, sea levels might rise as much as 2.5 meters above their current levels, which would seriously threaten coastal cities and other low-lying areas. Hansen's 2016 Prediction of 2−5m Sea Level Rise Proves Accurate. Joe Raedle/Getty Images Last summer, James Hansen—the pioneer of modern climate science—pieced together a research-based revelation: a little-known feedback cycle between the oceans and massive ice sheets in Antarctica and Greenland might have already jump-started an exponential surge of sea levels.
That would mean huge levels of sea level rise will happen sooner—much sooner than expected. Hansen’s best estimate was 2 to 5 meters (6–15 feet) by the end of the century: five to 10 times faster than mainstream science has heretofore predicted. The result was so important that Hansen didn’t want to wait. So he called a press conference and distributed a draft of his findings before they could be peer-reviewed—a very nontraditional approach for a study with such far-reaching consequence. That’s bad news for those of us rooting for a stable planet. In an email to Slate, Ruth Mottram, a climate scientist who was skeptical of the initial draft, calls the final study “considerably improved.”
50m Bangladeshi Refugees After 6" Sea-Level Rise. In some places, the impact of climate change is obvious.
In others, scientists predict that climate change will occur based on elaborate computer models. In Bangladesh, it is already happening at a scale that involves unprecedented human tragedy. I witnessed this in December 2016, when I visited Bangladesh to give some talks at the University of Chittagong. December 9, 2016. “How do they survive?” December 18, 2016. December 25, 2016. Are Rising Sea Levels Dramatically Underestimated? Coastal cities across the world are threatened by rising sea levels, but a new study has found that we might be significantly underestimating the risk.
The study, published in the journal Nature, shows that Antarctica’s ice cap is less stable than previously thought and sea levels could rise more rapidly than predicted. Previous studies had predicted sea level rises of up to a metre this century, however these projections failed to anticipate any significant contribution from Antarctic ice. Scientists Suggest Rate Sea Level Rise Likely To Increase. One of the great things about science is that it allows you to make predictions.
Three top climate scientists just made a very bold prediction regarding sea level rise; we should know in a few years if they are correct. As humans emit greenhouse gases, it’s causing the Earth to warm. That’s indisputable and proven. We can actually measure the amount of extra heat. Study Reveals Stunning Acceleration of Sea Level Rise. The oceans have heaved up and down as world temperatures have waxed and waned, but as new research tracking the past 2,800 years shows, never during that time did the seas rise as sharply or as suddenly as has been the case during the last century. The new study, the culmination of a decade of work by three teams of farflung scientists, has charted what they called an “acceleration” in sea level rise that’s triggering and worsening flooding in coastlines around the world. The findings also warn of much worse to come.
