At this year's NY Climate Week, the biggest positive change I saw wasn't the buzz about some new technology or policy. It was people finally realizing that talking about climate is where action starts! Talking about climate isn't optional. It's where change begins 💚

DEVASTATING FLOOD Security camera footage shows the moment the flood crashes through the Nepal-China border. The flash flood wipes out everything in its path. People, houses, roads, and power projects were swept away in Nepal, while officials in Tibet said they feared “major casualties.”

Floods usually follow droughts. And droughts usually turn rainfall into floods as the dried out soil cannot easily absorb moisture. The higher global temperatures rise, the more extreme droughts and subsequent floods become.

My favourite Jane Goodall quotes....so many, so to the point, so wise. How different the world would be if enough people listened to her.
"People think hope is wishful thinking, and actually hope is about action." Quote from the Wiser Than Me podcast with Julia Louis-Dreyfus."Only when our clever brain and our human heart work together in  harmony can we achieve our true potential." Graphic by the Jane Goodall Institute of South Africa."You cannot get through a single day without having an impact on the world around you. What you do makes a difference, and you have to decide what kind of difference you want to make." Graphic by Ariana Huffington on Instagram.

Two of the most common climate misconceptions I see, even among knowledgeable folks, are that (1) most people aren't worried about climate change, and (2) if they were, they'd act. Not true! Data show (1) most people are worried, but (2) they won’t act if they don’t know what to do-and most don’t.

Hundreds of millions of bees, almost 80% of bees in the US, have died over he past eight months. Researchers don't know why. Here is what this means:
Bees play a critical role in U.S. food production. In addition to making honey, they pollinate 75% of the fruits, nuts and vegetables grown in the U.S.
That's $15 billion worth of crops. Shook said the current losses are unsustainable.
"If this is a multi-year thing, it'll change the way we consume food in the United States," Shook said. "If we lose 80% of our bees every year, the industry cannot survive, which means we cannot pollinate at the scale that we need to produce food in the United States."

Climate change is not a religion. We don’t have to believe in it to make it true. We can say “I don’t believe in gravity” – but if we step off the cliff, we’re still going down. And if we take other people with us, we’re responsible.

In 1890, the Tariff Act came into place in the United States. It placed tariffs on imports of up to 50%. While touted as a way to build American industry, there was also the hope it would force an annexation of Canada. It backfired. Let's learn more. 🧵1/10
The image is a black-and-white political cartoon depicting a man in a suit standing behind a counter labeled "Republican Platform." He is holding a bottle labeled "Untaxed Whiskey, 20¢ Gal." in one hand and a piece of cloth labeled "War-Taxed Common Cloth, Tariff 84%" in the other. Above the counter, a sign reads, "If you don’t see what you want, ask for it." The cartoon, signed by W.A. Rogers, appears to satirize the Republican Party's economic policies, highlighting the disparity in taxation between luxury items like whiskey and essential goods like cloth.
