The world is getting hotter and more crowded and the two issues are connected, but not quite as much as people might think, experts say.

On Tuesday somewhere a baby will be born that will be the globe's 8 billionth person, according to a projection by the United Nations and other experts. The Earth has warmed almost 0.9 degrees Celsius (1.6 degrees Fahrenheit) since the world hit the 4 billion mark in 1974.

The world's biggest rainforest nations Brazil, Indonesia and the Democratic Republic of Congo on Monday formally launched a climate partnership to work together on conservation.

How do you stop a cow from burping?

It might sound like the start of a humorous riddle, but it's the subject of a huge scientific inquiry in New Zealand. And the answer could have profound effects on the health of the planet.

She has pedaled thousands of miles from Sweden to Egypt's Red Sea resort of Sharm el-Sheikh to deliver a simple message: Stop climate change.

The trip took 72-year-old activist Dorothee Hildebrandt and her pink e-bike — which she fondly calls Miss Piggy, after the temperamental character from The Muppet Show — more than four months. She crisscrossed Europe and the Middle East until she arrived in Sharm el-Sheikh, at the southern tip of the Sinai Peninsula.

Between the cliffs and crags of Israel's submerged prehistoric coastline, a Mediterranean ecosystem is surging back to life.

Giant groupers flourish among the rocks, a psychedelic purple nudibranch sea slug clings to an outcrop, and a pair of rays skate along the undisturbed sandy bottom.

From a distance, the endless landscape of solar panels stretching toward the horizon can easily be mistaken for crops nearing harvest. But here in the desert in southern Egypt, workers have been cultivating another precious commodity: electricity.

After the sun strikes the photovoltaic solar panels, a thermal charge generates electricity that runs to four government-owned power stations distributing power across Egypt's national grid.

U.S. President Joe Biden has left Washington for a global climate meeting with a giant domestic investment in tow — and likely to face questions about how far the U.S. will go to pull other large greenhouse gas emitters along.

His attendance Friday at the U.N. climate conference, known as COP27, in the resort town of Sharm el-Sheikh, Egypt, is the first stop on an around-the-world trip that will also take him to a meeting of Southeast Asian leaders in Cambodia and a Group of 20 summit meeting for leaders of the world's largest economies in Bali, Indonesia.

Shortly after Hurricane Nicole made landfall early Thursday along the east coast of Florida, it was downgraded to a tropical storm but it was still battering a large area of the storm-weary state with strong winds, damaging storm surge and heavy rain.

The rare November hurricane prompted officials to shut down airports and theme parks and order evacuations in areas that included former President Donald Trump's Mar-a-Lago club.

The climate change generation is saying officials are talking too much, listening too little and acting even less. And they are fed up.

"Instead of talking about how to solve the climate crisis, they negotiate about how to continue polluting," said Mitzy Violeta, a 23-year old indigenous activist from Mexico. "Youth movements are realizing the solution isn't going to be in international gatherings," like the one taking place in Egypt.

Samantha Power, the Administrator of the United States Agency for International Development (USAID), on Wednesday announced $8.5 million in funding for Lebanon that will support 22 new solar-powered water pumping projects in Lebanon. These projects, which will be completed over the next two years, will serve more than 150 towns and villages and benefit over half a million Lebanese citizens and refugees by providing reliable access to water and decreasing operating costs and dependence on fuel to those who desperately need it.

"USAID has supported 41 solar energy projects to date benefiting 460,000 residents in 70 Lebanese towns and villages. In addition to providing a much-needed source of electricity, solar-powered water pumping projects also refurbish the stations’ chlorination equipment. Pumping chlorinated water to towns is particularly critical as the country addresses an unprecedented cholera outbreak," the U.S. Embassy said in a statement.
