Plants on Earth have grown for hundreds of millions of years, yet President Donald Trump’s pick to lead his new climate team insists that they need more carbon dioxide (CO2) to boom.
Princeton physicist and carbon dioxide-advocate William Happer has been selected to head the brand new Presidential Committee on Climate Security. The atomic scientist, who achieved recognition for his work on atomic collisions (原子碰撞), not climate science, declared that the planet’s atmosphere needs significantly more CO2, which is reported to speed up climate change. Happer said plants use CO2 to live and more CO2 is actually a benefit to the Earth. He also stressed that Earth is experiencing a “CO2 starvation”, and concludes that “If plants could vote, they would vote for coal.”
Earth and plant scientists, however, find Happer’s insistence that the plant kingdom would benefit from increased CO2 wrong-headed and it lacks evidence. For example, Earth’s CO2 levels have increased sharply in the last century, and are now at their highest levels in at least 800,000 years—though other measurements show CO2 levels are higher than they’ve been in 15 million years. “The idea that increased CO2 is universally beneficial ‘to plants’ is very misguided,” Jill Anderson, an evolutionary ecologist specializing in plant populations, said in an interview. Data shows the evolution of global average temperature and CO2 concentration from 1850 to 2019. Though 2019 is a bit cooler than recent years, it still is one of the warmest years ever and lies close to the trend line of global warming.
Both independent academic organizations and government agencies around different parts of the world concluded more CO2 will bring many negative impacts to plant environments. And they added that “If someone is going to claim it is good, it’s necessary for them to show evidence.”

It’s not common that a grandmother aged 89 is crowned Queen of Icebergs in north America, but when it does happen it’s quite the sight.
On a recent trip to Iceland, Judith Streng became that grandma after her son attempted to take a photograph of her sitting on an ice structure that looks like a throne (宝座) at Diamond Beach in Jokul. Shortly after Streng sat down to pose, the piece of ice broke off and floated into the water.
“I thought it was safe. One girl had been on it and then two girls at the same time, and it was very secure with them. When I got on it, it started to shake and a wave was coming in. A very large wave came in and made the throne kind of shake, and I could tell that I was slipping off,” Streng told ABC News.
Streng’s story went hot after her 24-year-old granddaughter Catherine tweeted a text message exchange she had with her father about the incident. “My grandmother almost got lost at sea in Iceland today!”
Catherine, who teaches English in Seoul, South Korea, explained via Twitter that her father described the scene vividly. He has a PhD in English, and described the event in the following words, “She climbed to the throne after a wave had pulled back and left it briefly exposed on the beach. Then a wave washed in and removed the ice throne, rocking it from side to side. When the wave left, it lifted the throne and carried her out into the sea with the tide.”
Luckily for the Streng family, Randy, a licensed boat captain from Florida with knowledge of water rescue strategies witnessed the whole thing, and was able to save the day.
