The Deadliest Extreme Weather Events May Surprise You

In Clark County, Southern Nevada, the coroner’s office reported last week that there have been 29 heat-related fatalities since the same time frame in 2024. A study released earlier this year by Climate Central, a nonprofit organization.

The county documented its first heat-related death of 2025 on May 9th. Last year was particularly deadly for Southern Nevada, with 527 heat-related fatalities reported, according to the Clark County Coroner’s office.

The National Weather Service noted that the summer of 2024 marked the hottest on record for Southern Nevada. Las Vegas set a new high of 120 degrees Fahrenheit last July, experiencing over 100 days of triple-digit temperatures.

In Maricopa County, Arizona, 15 heat-related fatalities have been noted as of July 19th. This number is consistent with the 23 confirmed deaths by July 19, 2024, although public health records indicate that 299 deaths this year are still under review.

Last May, the Maricopa County Public Health Department reported that at least one heat-related death occurred daily in the county from June 18th to July 31st.

In 2024, the county experienced its hottest year on record, with officials confirming 602 heat-related deaths, a decline from the record 645 deaths in 2023.

Local authorities have initiated several new strategies to keep residents cool and safe during the summer. These efforts include planting trees to enhance shade in public areas and resurfacing pavements with more reflective materials to mitigate urban heat.

“For many people, heat is a nuisance, but for others, it can be a matter of life and death,” emphasized Ariel Choinard, a scientist at the Las Vegas Desert Research Institute and director of the Nevada Heat Lab.

Certain demographics face higher risks, including the elderly, individuals with chronic health issues, and young children who may struggle to articulate their feelings, she noted.

Exposure to extreme heat disproportionately impacts low-income communities, according to Choinard. While everyone in cities like Las Vegas endures the summer heat, the experience of that heat varies based on housing stability, reliance on public transport, and access to air conditioning.

A study published in August 2024 in the Journal found that from 1999 to 2023, there were 21,518 heat-related deaths in the United States. The research indicates a rise in heat-related mortality rates over the past two decades, particularly intensifying in the last seven years.

The Top 10 Deadliest Spiders on Earth

Poisonous spiders are known as some of the deadliest and most dangerous creatures in the world. They are the stuff of nightmares and horror movies, famous for their ability to paralyze and subdue their prey while still alive.

While most spiders have venom glands, only some pose a threat to humans. Certain species can cause pain and discomfort similar to bee or wasp stings, while others can be more severe.

If you are unfortunate enough to be bitten, seeking medical advice and treatment is recommended.

Here are the top 10 deadliest and most venomous spiders to be aware of:

10 – Mouse Spider

Mouse spiders, despite their name, do not actually eat mice. They are named for their underground burrowing habits rather than their prey.

While their venom can cause headaches and numbness, mouse spiders are not typically aggressive, and there is generally no cause for alarm despite their intimidating appearance.

9 – Lycosa Tarantula Spider
