Warming Seas and U.S. Coral Reefs: Lighting the Fuse
An Increasingly Warm Sea
You might've noticed that ocean temperatures have been steadily rising over the past century, and it's not just a fluke. From 1901 through 2023, sea surface temperature rose at an average pace of 0.14°F per decade. The past few decades? Yep, they've been sizzling hotter than any other period since reliable records began in 1880.
The ocean, covering over two-thirds of the Earth, plays a pivotal role in regulating our planet's weather and climate. It's like a big, endless heat sponge, soaking up an estimated 91% of the excess heat energy trapped in our atmosphere due to greenhouse gases. This heat absorption causes the ocean's surface temperature to rise, with disastrous consequences for our coral reefs.
A Hot Mess: The Downside of Warming Seas
With the ocean and atmosphere constantly intertwined through the water cycle, a higher average global sea surface temperature can have alarming impacts on climate and weather systems. This sizzling heat increases the amount of water vapor over the ocean, upping the risk of heavy rain and snow events. Plus, it can potentially shift storm tracks and contribute to droughts in some areas.
Rising ocean temperatures also trigger rises in sea levels through thermal expansion and shifts in the distribution of marine species. Many marine species, including corals, rely on specific thermal and nutritional conditions for survival.
Note: It's important to recognize that the warming ocean is only one piece of the climate change puzzle. Greenhouse gas emissions, deforestation, and other human activities also play significant roles in altering our planet's climate
The good news is, we can now keep an eye on these changes thanks to satellite technology. It's like having X-ray vision for the ocean, with detailed views of daily sea surface temperature changes that help us better understand how global warming affects marine ecosystems.
U.S. Coral Reefs on Thin Ice
US coral reefs are precious gems in the ocean, teeming with marine life and offering coastal protection. Unfortunately, they're increasingly threatened by changes in ocean temperatures and chemistry. You can find these reefs near the Florida Keys, Hawaii, Puerto Rico, and other Pacific territories – not just for their beauty, but for the economic benefits they bring, contributing roughly $836 million in Hawaii alone through shoreline protection and flood prevention.
Rising ocean temperatures and acidity caused by greenhouse gas emissions are taking a toll on US coral reefs, causing more frequent coral bleaching and diseases. They slow down coral growth and overall health, and some reef systems are hit harder than others. The Florida Keys, for example, have seen a 53.8% decline in stony coral cover from 1996 to 2015 due to thermal stress, disease, and damage from hurricanes.
Climate Change's Devastating Impact on Coral Reefs
The domino effect of warming oceans has immediate and long-term effects on US coral reefs. As the oceans continue to warm, we each play a crucial role in protecting coral reefs.
PS: Don't forget the key factors other than warming oceans that contribute to climate change, like greenhouse gas emissions, deforestation, and other human activities
Let's Take Action for America's Reefs
From Florida to Hawaii, initiatives are underway to conserve coral reefs, focusing on supporting reef health through science-based management, restoration initiatives, and pollution control.
In Florida, projects like the Coral Reef Evaluation and Monitoring Project (CREMP) have been tracking the health of coral reefs since 1996, providing necessary data for conservation strategies.
Across Puerto Rico, the Trash-Free Waters initiative aims to eliminate aquatic trash through collaborative efforts among agencies, states, and businesses. This initiative is part of a broader strategy to protect marine environments from pollution.
The EPA supports the Hawaii Coral Reef Working Group, coordinating coral reef management efforts in the Hawaiian Islands. They provide guidance to the State of Hawaii's Coral Reef Program on conservation actions, including community outreach and scientific research, that aims to mitigate the main threats to Hawaii's coral reefs.
These collaborative efforts underscore the pivotal role of coral reefs in marine ecosystems and their importance to coastal communities. Remember, with daily sea surface temperatures only on the rise, protecting coral reefs has never been more crucial.
