1 . A possible treatment for Florida’s disastrous red tides (赤潮) took another step toward widespread use after successful testing in Sarasota Bay.

This study, led by UCF Assistant Professor of Biology Kristy Lewis, is the first successful test of any red tide treatment technology in open water using large water containers (容器). These containers — about six feet in diameter — extend from the waters’ surface to the ocean floor, allowing scientists to test real ocean conditions within a controlled setting. Four containers were treated with a clay (黏土) solution, while the other four served as a control.

The clay along with the Karenia brevis algae (海藻), which is responsible for Florida red tide, is put on the ocean floor. Lewis has spent the last three years carefully testing the impact of introducing this clay into the ocean ecosystem. She not only looks for changes in the water’s quality, but also wants to know how the clay affects the health of sea life. “We want to make sure the treatment is not worse than the disease,” she says.

At first, the test was simply to measure the influence of the clay on the ecosystem, but an unexpected red tide event caused Lewis to make the test practical. The results suggest the clay performed as expected, but there’s still a question of whether the bad effects of algae remain active on the ocean floor. Water collected during the test should provide an answer. Next steps depend on the test results, but there are already plans to survey what happened to the clay-coated algae when it’s used near seagrass beds.

Visiting Sarasota. Florida, in the middle of a red tide event reminded Lewis just how important the research is to keep the state’s coast healthy. Lewis says she’s prepared to go another three years if that’s what it takes to find an acceptable solution to red tides.

3 . Several art projects are on show to warn people of the climate change happening around us.

Video on the walls

Photographer Camille Seaman has traveled to both the North Pole and the South Pole, where she has captured the disappearing ice in photographs and video. Camille Seaman made a video with some of her most powerful photos of melting ice for people in four coastal cities to display on their buildings. The video ends with a prediction that sea level will rise by 2050 without relative action.

Mural (壁画)changing color

Temperatures in Austin, Texas, are on the rise, and climate change will put the city at higher risk of extended drought, wildfires, intense rain and flooding. Artist Lope Gutiérrez-Ruiz designed a unique mural that changes color as it gets hotter. This art work calls for people to change the world and change climate change, underlining the importance of individual actions to the collective future.

Public billboard   (广告牌)

Artist Christine Sun Kim released a public billboard on the 710 Freeway called The Sound of Temperature Rising. It points to the reality of climate disaster that has become all too clear on the West Coast and the need for significant change now. The illustration features a graph (图表) of music notes that get progressively longer and redder.

Anti-Extinction Library

Globally, species are disappearing at an unheard-of rate. In response, architect Mitchell Joachim created The Anti-Extinction Library in New York. The sculptural piece is not only beautiful but also functional. Their unique egg-shaped library has a special freezer storing test tubes with the frozen cells and DNA of rare animals and plants. It’s important for people to realize we must quickly work to protect the rights of different species in our area.

4 . Are flash floods becoming more severe? Natural disasters are generally getting worse—and that's true for floods, too.

As climate change warms the atmosphere, extreme rainfall is rising, which increases the risk of flash floods. Heavy precipitation(降水) events are predicted to increase by 2 to 3 times the historical average. The Federal Emergency Management Agency expects the nation’s floodplains to expand by 45 percent by the end of this century, as the agency reported in a recent study. A study in early 2021 found that increased precipitation—resulting partially from climate change—costs the US an additional $ 2.5 billion each year in flood damage. And some studies show that flood frequency was increasing in the Mississippi River valley and across the Midwest in the last century, as well as in the Northeast over the past 50 years.

There are several steps you can take to prepare for flash floods

First, know the level of risk by looking at flood maps. You may be required to have flood insurance if you live in a high-risk area.

Pay attention to flash flood watches, which the National Weather Service issues to indicate when conditions could result.in flash floods. People in these areas-should be-ready to take action—particularly if the NWS announces a flash flood warning. That’s issued when flash floods are approaching and, at that point, people should immediately leave the area.

But be particularly careful when travelling by car. Don’t drive through flooded streets—it's difficult to judge the water depth, and roadways hidden below the water can collapse. If floodwaters cause your vehicle to lose control, abandon it and seek the higher ground. Rapidly rising water can sweep the vehicle away. Know your surroundings and head to the higher ground, and listen to the radio updates when in a flood.

It’s also important to develop an emergency prepared plan with your family or those you live with to have a few days’ worth of resources.

9 . In the middle of the night, a baby chimpanzee (黑猩猩) is having nightmares. Chantal, his caretaker, tries to calm him down. She works at the Tchimpounga Chimpanzee Rehabilitation Center, in the Republic of the Congo, in Africa. The chimp’s name is George. He was taken from his mother by hunters. Finally, he was rescued and taken to the sanctuary (鸟兽保护区), where Chantal helped him make friends with other chimpanzees. “We rescue chimps from terrible conditions and help them to live in the wild like other chimpanzees,” Chantal said, “They need to learn chimp behavior.”

Chimpanzees meet a lot difficulties because people cut down forest and illegal (非法的) wildlife trade. Their population, numbering in the millions a century ago, could be down to 172,000. This makes the work of the Tchimpounga Sanctuary even more important.

When opening in 1992, Tchimpounga had space for 60 chimpanzees. It has been made larger to the size of a hundred football fields, and provide home around 150 chimps. Many live on islands with thick forest in the Kouilou River. In that environment, the chimps are prepared for a possible return to the wild. The sanctuary also works with the government to reduce illegal trade in animals. Tchimpounga’s head veterinarian (兽医) Rebeca Atencia said, “We have effectively reduced the arrival of orphan (孤儿) chimpanzees to Tchimpounga. We’ve received only one orphan chimp over the past three years.”

The chimps have shown that they understand the sanctuary staff’s efforts. “Saving the life of a chimpanzee is very gratifying,” Atencia says. “Chimpanzees know when you’re helped them or saved their life. Sometimes, they thank you with a hug.”

As the leader of Jane Goodall Institute (JGI), Atencia also works with people who live near the sanctuary. These people depend on the forest for food and building houses, and their growing population is a danger to chimps. JGI helps the people in these places get healthcare, clean water, and others. This makes them less dependent on the area’s natural resources and reduces illegal trade in chimps. At present, there are islands within the sanctuary where the chimps can be safe from wild chimpanzees and hunters. And they’ re still under the care of the sanctuary staff.
