The U.S. coastal sea level is projected to rise by at least one foot over the course of the next 30 years, the same amount recorded over the last century, according to the nation’s leading climate researchers.
The expected sea-level rise will lead to a“profound increase” in coastal flooding, even if heavy rainfall remains at current levels, scientists at the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) said in an extensive 111-page technical report published Tuesday.
“This report is a wake-up call for the United States,” NOAA Administrator Richard Spinrad remarked during a press briefing Tuesday.
Major and moderate“high tide flood events” are projected to become as frequent as moderate and minor flood events are today, according to the report. The researchers said domestic coastal infrastructure, communities, and ecosystems will face serious consequences from the tide level rise.
The urgent report blamed global warming for the increasing sea level, saying that conditions could worsen.
“Science is indisputable and urgent action is required to mitigate a climate crisis that is well underway,” NASA Administrator Bill Nelson said in a statement.
Nelson said that the report showed sea levels rising at a“very alarming rate” which was“endangering communities around the world.”
“For businesses along the coast, knowing what to expect and how to plan for the future is critical,” Secretary of Commerce Gina Raimondo said in a statement. “These updated projections will help businesses, and the communities they support, understand risks and make smart investments in the years ahead.”
White House climate adviser Gina McCarthy said the report represented a“blinking code red” for the world. She said it’s imperative that the U.S. “redouble” its efforts to cut carbon emissions.
In an effort to combat climate change, President Joe Biden has pushed renewable energy alternatives to traditional fossil fuels, including solar and wind. The White House has outlined plans to ensure the entire U.S. grid is carbon-free by 2035 and the economy reaches net-zero emissions by 2050.
The Biden administration has also waged a war on traditional energy production, nixing the Keystone XL pipeline, ditching an oil drilling project in Alaska, and confirming it would review the possibility of shutting down a Michigan pipeline supplying fuel to much of the Midwest.
While 2021 was colder than 2019 and 2020, it marked the world’s sixth-warmest year on record, the NOAA said. A United Nations report released in August 2021 warned that the world was likely to warm more than 2 degrees Celsius above pre-industrial levels by 2100.
