An international team of researchers has found that dam building in the 20th century offset some of the factors that would have led to a higher rise in sea levels. In their paper published in the journal Nature, the group describes their study of the factors that have led to a rise in global sea levels and what they learned.
Just north of the Golden Gate Bridge, yet a world away from San Francisco, in an unincorporated and oft-overlooked area known as Marin City, sea level rise is rarely the first worry that comes to mind. Traditional flood maps for this predominantly Black and working-class community suggest that the area is safe from rising water until 3 feet or more. But sea level rise is a lot more complicated than just waves breaking over seawalls and beaches disappearing.
If California lawmakers set aside climate concerns like sea level rise, and focus only on the pandemic, the state could be setting itself up for an even worse economic hardship, the nonpartisan Legislative Analyst’s Office cautioned in a report Monday.
The state will suffer dire long-term consequences if lawmakers set aside concerns about rising seas to focus solely on COVID-19, the non-partisan Legislative Analyst’s Office warned Monday.
Sea level rise will likely put at least $8 billion in property underwater by 2050, and could affect tens of thousands of jobs and billions in gross domestic product, according to studies cited by the office.
California’s beaches may feel off-limits right now, but the coronavirus has not stopped the sea from rising. With every tide and storm, this slow-moving disaster continues to creep closer to shore — toppling bluffs, eroding our beaches and threatening homes and major infrastructure.
The view from high up in Del Mar’s 17th Street lifeguard station is a visit-California poster: a sweeping curve of sand, dramatic coastal bluffs, a welcoming sea. What scientists see, though, is somewhat more sobering: the Pacific Ocean as seething menace, a marine battering ram born of climate change that will inexorably claim more and more land and whatever sits upon it.
With rising seas now posing a greater threat to California’s economy than wildfires or severe earthquakes, state authorities are cautioning those who live along some of the Golden State’s famous beaches to do what they’re loath to do: retreat. Turn their backs to the sea and move homes, businesses, schools and critical infrastructure out of harm’s way.
The ocean could rise two to ten feet by 2100, imperiling $150 billion in property, according to state estimates, and erasing two-thirds of California’s beaches.
There is a 75 percent chance 2020 will set a record for the warmest year since instrument records began in 1880, the National Oceanic and Atmospheric Administration is projecting, beating out 2016 for the distinction.
This is somewhat unexpected, since there is no declared El Niño event in the tropical Pacific Ocean, which tends to provide a natural boost to global temperatures that are already elevated due to the human-caused buildup of greenhouse gases in the atmosphere.
The NOAA projection, made late last week, is based on statistical modeling now that the first quarter of 2020 is off to a near-record warm start, coming in as the second-warmest January through March period since instrument records began in 1880.
A bold new plan to protect California’s ocean ecosystem from climate change and prepare for sea-level rise was approved Wednesday, setting the stage for sweeping coastal restoration, trash cleanup, research and rule-making involving numerous state agencies.
The strategic plan, adopted unanimously by the state’s Ocean Protection Council, is a blueprint for how state agencies should collaborate over the next five years with tribal groups, research organizations and underserved communities to prepare for ocean warming, acidification, rising seas and plastic pollution.
People love the Golden State because of the coastline. There are all sorts of songs about the vibe California embodies — think “California Gurls” by Katy Perry, “Californication” by the Red Hot Chili Peppers and “California Love” by 2Pac.
But the ocean’s response to climate change is threatening that very identity.
Despite years of urgent warnings, local governments are moving too slow to prevent the worst damage from sea-level rise caused by climate change, risking repercussions as severe as housing shortages or an injured state economy, according to a report released today by the Legislative Analyst’s office. The report suggests California would need to start building 100,000 more housing units annually in coastal cities to mitigate the problems caused by sea-level rise. Funding for public schools might be affected as well, as higher sea levels hurt property values and lower tax revenue. And it’s not just beachside housing that will be impacted.
