Today's top stories
As world leaders gather for the annual United Nations climate change summit, known as the Conference of the Parties or COP28, in Dubai tomorrow, one number will be top of mind: 1.5 degrees Celsius (2.7 degrees Fahrenheit). It's the amount countries have agreed to limit warming by the end of the century — an amount they're not on track to meet. These are the climate impacts the U.S. will see if warming goes beyond 1.5 degrees.
Meanwhile, President Biden will skip the summit and head to Pueblo, Colo., to focus on his domestic agenda and talk about investments in clean energy jobs. He's also expected to take swipes at right-wing Republicans like Rep. Lauren Boebert, who represents the district in Pueblo.
Secretary of State Antony Blinken is heading back to the Middle East, where he's expected to press for more humanitarian aid for Gaza and help secure the release of hostages. His trip comes after a meeting with NATO foreign ministers in Brussels, where Russia's war with Ukraine was at the top of the agenda.

The average U.S. life expectancy is now 77.5, according to provisional 2022 data published by the CDC. It's the first time the number has risen in two years when the COVID-19 pandemic caused a sharp decline. Still, researchers say U.S. life expectancy lags far behind other wealthy countries.

What does a billionaire know about how to find happiness?
Oprah Winfrey has the money to BUY herself happiness, but it's not stopping her from searching for ways to find it.
She co-wrote a book with Arthur Brooks titled Build the Life You Want: The Art and Science of Getting Happier. I spoke to them about it, and they both agreed that finding happiness does not mean eliminating unhappiness from your life. That makes sense. How would you recognize the happy moments unless there are unhappy ones to compare them to? Oprah (yeah, we're on a first-name basis) calls it striving for happier-ness.
It also lines up with something Thomas Jefferson wrote in the Declaration of Independence 247 years ago: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
Notice that he had the foresight not to describe happiness as a right that can never be taken away. For some or most people, it might be impossible to achieve. But you should always have the right to try to find it...just like Oprah is. Listen to our conversation and watch it on Instagram.

The cycle can continue when adults who've experienced trauma have kids of their own. The intervention program HealthySteps aims to help families with lower incomes break this cycle.
