Ghosts, goblins and … global warming?

For South Berkeley resident Julie Twichell, Halloween might be a time for creepy creatures and costumes, it’s also the perfect time to educate trick-or-treaters about the scariest topic of all: climate disasters. To that end, she has dedicated half the yard in front of her Craftsman bungalow at 3204 Tremont St. to a display depicting an oil spill.  

The homemade scene includes a 3-foot cardboard oil tanker and a river of black oil created by rolls of plastic, which cover up the blue plastic waters. The black “oil” turns into a painted surface that runs off the display and across the sidewalk. Black metal ducks and two crows represent oil-covered wildlife. Behind it all are the flames of wildfires, climbing along the home’s façade. Nearby, posters hang or are inserted into the ground, including a homemade one demanding to “Stop Adding Fuel to CA Wildfires! $ Big Oil has always known fossil fuels harm the climate.” 

“One of the scariest things happening today is climate disasters. We need to act much quicker than we had imagined,” said Twichell, 66, a retiree who spent a quarter of a century educating the public about lead poisoning for Alameda County. She sees her display as a continuation of her role as educator.

“For the younger people, their lives will be dramatically impacted,” she said. “People are going to lose their livelihoods. Their lives. That is scarier than any ghost or goblin.”

Though visions of global disaster may be an unusual way to decorate for Halloween, Twichell and her friend Rosemary Ehat wanted to include a more positive display to leave children with hope. “We think it is very possible to turn things around,” Ehat said. 

The other side of the garden includes things “we can do to make change,” Ehat explained, represented by images of happy children and zero-emission toy busses and trucks. One poster shouts, “Rise for Climate Jobs and Justice!” Another, depicting a girl jumping in the air, proclaims “The Freedom to Breathe!” 

The treats Twichell will be offering will also have a green theme: chocolate globes and packets of pollinator seeds.
