Are Your Ready for the Behavioral Consequences of Climate Change?

This July was the hottest month in recorded history – possibly the hottest on Earth in the past 125,000 years. In addition to contributing to the frequency, intensity, and duration of storms and floods, droughts, wildfires and sea-level rise, heat distorts human behavior. The changing climate is already affecting every part of personal and professional life, and there is increasing acknowledgment that climate change acts as a “threat multiplier” for various adverse behavioral impacts. It has a direct, demonstrable influence on human behavior that must be understood and factored into policies, plans, procedures, and even exercises. Leaders and decision-makers cannot afford to get behind the curve in preparing for this reality. Now is the time to adopt a climate-informed approach to managing the risks ahead.

To help professionals adapt to and mitigate the behavioral consequences of climate change, the Homeland Security Human Factors Institute™ is offering a four-part series, “Climate-Informed Security, Emergency Management and Business Continuity.” The professional development program will run from October 4 through October 25, on Wednesdays from 1:00-2:00 pm EDT. Participants can take individual classes or enroll in the four-session certificate program. All programs are recorded for convenient on-demand viewing, and participants have access to the presentation materials as reference tools.

Climate change is emerging as one of the most significant global issues of our time.  Our climate is now changing at an unprecedented and alarming rate with profound impacts on human life. As our awareness and understanding of climate change increases, the links between climate change and human behavior will become increasingly important to those tasked safety and security in the workplace, campus, and community. Don’t miss this opportunity to be a thought leader in your organization. Learn more and register today for the fall professional development series at


New series offers an intimate look into how climate change impacts the lives of wildlife

Climate change is often in the form of extremes in weather like sweltering heat domes, devastating inland flooding or record breaking wildfire seasons, which puts lives and livelihoods at risk for humans. However, the world’s animals who are on the front lines of an ever changing planet experience these changes a little differently.

“When we see climate change in the news, we often think of big storms or major weather events but animals are vulnerable to the smallest changes,” wildlife filmmaker and host Bertie Gregory tells PopSci.

In the new series “Animals Up Close with Bertie Gregory,” viewers can get a look into these subtleties and changes. In one episode, the team is searching a dive spot in Indonesia for the elusive devil ray, when a swarm of hundreds of jellyfish approaches.

“Avoiding their stingers was like playing a video game! We were told that huge jellyfish plumes like that were becoming a more regular sight in these tropical waters, which is not a good sign,” Gregory says.

When Gregory checked the dive thermometer, it read 87.8 degrees Fahrenheit, in water that should have been about 82 degrees. A few degrees might not always sound like much, but has an outsized impact on animals.  “Jellyfish are thought to tolerate climate change better than other species, hence their huge numbers on that day. For us, it meant no other signs of life,” says Gregory.

The series spans the planet and uses high-tech drones and cameras that Gregory calls a “game changer” for wildlife filmmaking. The tech allows the filmmakers to catch a glimpse of the outer lives of animals and even some of their more inner workings.

“We also used a military grade thermal imaging camera to film elephants at night in the depth of the jungle in the Central African Republic—it uses heat to “see” in the dark and elephant ears look incredible as you can see all their veins!” says Gregory.

The series also captures just how difficult it is for terrestrial animals like the pumas of Patagonia and marine mammals like Antarctica’s orca whales to get a solid meal and how climate change continues to threaten vital food sources.

An episode features a group of Antarctic orcas known as the B1s during what Gregory says was the warmest Antarctic trip he has ever experienced. These killer whales are known for a unique strategy to hunt seals resting on the ice that might remind some orca enthusiasts of the hydroplaning killer whales near Argentina’s Valdés peninsula who thrust their 8,000 to 16,000 pound bodies up onto the beach to catch seals.

“We witnessed and filmed the staggering intelligence and adaptability of a group of killer whales. There are thought to be just 100 of these unique killer whales in existence, and during filming it was clear they were struggling to ‘wave wash’ seals from ice because there wasn’t much ice,” says Gregory.

The whales had to constantly adapt their strategy just to get a single seal, sometimes risking an escape from their prey in order to teach the younger whales strategies to carry on to the next generation.

These constant struggles offer up sobering reminders of the macro and micro ways that the planet is changing and making life more difficult for almost every living thing.. Over one million animal and plant species are threatened with extinction, a rate of loss that is 1,000 times greater than previously expected. The  United Nations agreed upon a biodiversity treaty at the end of 2022 pledging to protect 30 percent of the Earth’s wild land and oceans by 2030. Currently, only about 17 percent of terrestrial and 10 percent of marine areas are protected through legislation.

Despite climate change’s constant challenges, the area is a conservation success story thanks to community-led initiatives to protect the area from overfishing by implementing specific parts where fishing is allowed.

“Now, Misool is one of the few places on earth where biodiversity is increasing. What they’ve managed to do could be a blueprint for how we can protect oceans around the world and proof that if given the chance, nature can make an amazing comeback,” says Gregory. “It’s good news for wildlife and good news for people.”
