About 8.4 billion people — or almost 90 percent of the projected global population — could be exposed to malaria or dengue fever by 2080 if greenhouse gas emissions continue to surge, according to a new study published in The Lancet Planetary Health.

World Population Day is an occasion to reflect on how the world can best address the challenges posed by the combination of urbanization and climate change.

Population growth, agricultural withdrawals, and, increasingly, climate change have badly diminished the Gila River and threaten its future.

In the midst of a climate crisis with 8 billion humans on the globe, it's absurd to say that what's lacking is babies.

We discuss the myth that Canada has plenty of room for a much larger population, and the many reasons further population growth and "development" in Canada diminishes biodiversity, ecosystem health and quality of life.

More than 5 million people die each year globally because of excessively hot or cold conditions, a 20-year study has found – and heat-related deaths are on the rise.

Nearly 700 million people worldwide live in low coastal zones vulnerable to sea-level rise and coastal storms. That number could reach a billion by 2050. At first (including now), some people will have the resources to move. Others won't.

New research indicates that people in urban areas, on average, have the smallest carbon footprints, and those living in the suburbs the highest.

Facing drought and population growth, some Western U.S. towns are running out of water for new connections, stopping development. It's a challenge that's expected to grow as the climate changes.

Scientists have long feared for the future of this densely populated strip of land atop porous limestone as rising global temperatures increase sea levels.

Scientists calculate that by 2100, over 400 million people could live in low-lying, at-risk areas—and that's a conservative estimate, not factoring in explosive population growth in the world's cities.

The Minnesota city on Lake Superior is earning a reputation as a future destination for climate migrants. Experts say the entire Great Lakes region is primed for an influx, prompting questions on how to prepare for coming change.
