Some misguided people, today, who may call themselves "pronatalist", and who look at future predictions of negative population growth (meaning that population will decrease in the future, instead of continuing to increase), and see this as a problem, are wrong or are not thinking clearly. Some of them may believe that African and Arab and Asian populations are in the process of "replacing" or at least are overtaking the Caucasian, European-based ethnicities that have traditionally been the majority of the population in countries like the US, the UK, Europe, Canada, Australia and New Zealand; and they are right - this is indeed happening, as is the Hispanicization of the US population because of such massive immigration. And they are right to be concerned about this. In a century there may be no nations left on Earth where Caucasians of European ancestry are the majority of the population if immigration is not stopped. And this is a problem. There will be African majority countries, Asian majority countries, Arab majority countries, Hispanic majority countries, but there will not be any Caucasian of European ancestry majority countries left if we do not take action now.

'The sixth great extinction is happening', conservation expert warns

With her signature shawl draped over her shoulders and silver hair pulled back from her face, Jane Goodall exudes serenity - even over our slightly blurry video call.

In a Vienna hotel room, a press team and a small group of filmmakers, who are documenting her latest speaking tour, fuss around her.

Alarm call as world's trees slide towards extinction

Scientists assessing dangers posed to the world’s trees have revealed that more than a third of species are facing extinction in the wild.

Warmer air is melting the top of the Greenland Ice Sheet

If you could shape an ice cube out of all the ice losses from Greenland and Antarctica over the past three decades, it would stand 20km high.

An international group of scientists who work with satellite data say the acceleration in the melting of Earth's ice sheets is now unmistakable.

They calculate the planet's frozen poles lost 7,560 billion tonnes in mass between 1992 and 2022.

Seven of the worst melting years have occurred in the past decade.

Mass loss from Greenland and Antarctica is now responsible for a quarter of all sea-level rise.

This contribution is five times what it was 30 years ago.

The latest assessment comes from the Ice Sheet Mass Balance Intercomparison Exercise, or Imbie.

Sun-bleached skeletons of long-dead whitebark pine trees stand at the top of a 7,200-foot-high ridge along the Reservation Divide on the Flathead Indian Reservation, Montana. With annual average temperatures in Montana rising, the whitebark pine that were not previously threatened are now facing an increase in blister rust infections, mountain pine beetle infestations and wildfire.

Stretching from British Columbia, Canada down to parts of California and east to Montana, live the whitebark pine. The tree grows in subalpine and timberline zones — elevations anywhere from 4,000 to almost 9,000 ft. It's an unforgiving space. The wind is harsh. Plants and animals confront sub-freezing temperatures, often until summertime.

The whitebark pine has historically thrived in these lands. But today, the tree species is in trouble. So much so that the U.S. Fish and Wildlife Service listed the whitebark pine as a threatened species in December 2022. Increased fire intensity from climate change and colonial fire suppression practices, infestation by mountain pine beetles and a deadly fungus called blister rust — they're collectively killing this tree.
