Hawaii

Wildfires, pushed by powerful winds, raced through Lahaina, Hawaii, on Aug. 8 and 9, 2023, leaving a charred and smoldering landscape across the tourist town of about 13,000 residents that was once the capital of the Kingdom of Hawaii. Nearly 100 people are believed to have died in the fires, Maui County officials said. Others were rescued by the U.S. Coast Guard after going into the ocean to escape the flames. Dry grasses and strong winds, influenced by Hurricane Dora passing far to the south, heightened the risk as wildfires burned both in Maui’s tourist-filled west coast and farther inland and on the Big Island of Hawaii. Most fires in the U.S. are suppressed before they have a chance to threaten communities, but the winds were too strong to send helicopters into the sky to help contain Maui’s fires on the first day, leaving firefighters to battle the blazes from the ground. Lt. Gov. Sylvia Luke issued an emergency declaration, activating the National Guard to he...

Major wildfires on the Hawaiian island of Maui have killed dozens of people and caused heavy damage, particularly in the historic town of Lahaina, as of Aug. 10, 2023. The state has asked all visitors to leave Maui and those planning to travel there to reschedule their trips – a harsh blow to a destination whose economy relies heavily on tourism. University of South Carolina research professor Rich Harrill, an expert on hospitality and tourism, explains how such events affect places like Maui in the short and long terms. How tourism-dependent is Hawaii compared to other popular destinations? Compared to other destinations, Hawaii is very reliant on tourism – it comprises about 25% of the state’s economy. According to the Hawaii Department of Business, Economic Development & Tourism, visitor spending was projected to be US$20.8 billion in 2023 and $23.4 billion in 2026. Tourism plays an even greater role on Maui. Maui County has the state’s highest re...

The islands of Hawaii are world renowned for their generally pleasant and tranquil weather. However, the Aug. 8, 2023, wildfire tragedy on Maui was a stark reminder that Hawaii also can experience drought and hot, dry, windy weather, providing the conditions for destructive fires. Hawaii has seen a generally rising trend in the amount of land that burns each year as the local climate warms. Climate change was one of several contributors to Maui’s wildfire catastrophe, and rising temperatures and associated rainfall changes are expected to increase the islands’ fire risk. These changing weather patterns will also affect Hawaii’s ecosystems and freshwater resources. You can listen to more articles from The Conversation, narrated by Noa, here. I am a meteorologist at the University of Hawaii, and I have worked with colleagues to develop sophisticated computer climate simulations that project local rainfall changes over the 21st century. Our results sug...

The official 2023 hurricane season forecasts were just released, and while the Atlantic may see an average storm season this year, a busier-than-normal season is forecast in the eastern Pacific, meaning heightened risks for Mexico and Hawaii. A big reason is El Niño. El Niño typically means trouble for the Pacific and a break for the Atlantic coast and Caribbean. But while this climate phenomenon is highly likely to form this year, it isn’t a certainty before hurricane season ramps up this summer, and that makes it harder to know what might happen. It’s also important to remember that even in quiet years, a single storm can cause enormous destruction. As climate scientists, we study how climate patterns related to the frequency and intensity of hurricanes – information that is used to develop seasonal forecasts. Here is a quick look at how El Niño affects storms and why it tends to cause opposite effects in two basins separated only by a...

Honolulu has lost more than 5 miles of its famous beaches to sea level rise and storm surges. Sunny-day flooding during high tides makes many city roads impassable, and water mains for the public drinking water system are corroding from saltwater because of sea level rise. The damage has left the city and county spending millions of dollars on repairs and infrastructure to try to adapt to the rising risks. Future costs will almost certainly be higher. More than US$19 billion in property value, at today’s dollars, is at risk by 2100 from projected sea level rise, driven by greenhouse gas emissions largely from the burning of fossil fuels. Elsewhere in Honolulu County, which covers all of Oahu, many coastal communities will be cut off or uninhabitable. Unwilling to have their taxpayers bear the full brunt of these costs, the city and county sued Sunoco LP, Exxon Mobil Corp. and other big oil companies in 2020. Their case – one of more than two dozen involving U.S. ci...
