Air Conditioning Costs Rise With Arizona’s Heat

Air Conditioning Costs Rise With Arizona’s Heat

After Curt Tyler’s air conditioner broke down five years ago, he decided to rely on a swamp cooler to save money. Now he frequently swelters inside his own house — while saving more than $100 a month on his power bills. Air conditioning is becoming more vital as temperatures rise in the Southwest’s desert cities. That’s pushing up household … Read More

Report: The High Cost of Hot

Report: The High Cost of Hot

As additional carbon pollution continues to trap more and more heat in the atmosphere, the higher temperatures that result can come with a hefty price tag. Some of those costs hit our wallets in the form of higher energy bills from greater use of air conditioning. Warmer temperatures can also have major health impacts, increasing our … Read More

Antarctic Ocean Discovery Warns of Faster Global Warming

Antarctic Ocean Discovery Warns of Faster Global Warming

A group of scientists, including one from the University of Arizona, has new findings suggesting Antarctica's Southern Ocean — long known to play an integral role in climate change — may not be absorbing as much pollution as previously thought. The old belief was the ocean pulled about 13 percent of the world’s carbon dioxide — a greenhouse gas… Read More

Rising Seas Could Swell Arizona’s Population

Rising Seas Could Swell Arizona’s Population

Arizona’s low taxes and living costs, friendly culture, arts scenes and easy access to outdoor activities make it an appealing state in which to settle. And in decades ahead the state’s draw as a new home could be boosted as seas rise and oceans warm, forcing coastal residents to deal with fallout like strengthening storms, floods, mudslides and … Read More

Sea Level Stakes for the Caribbean, in Pictures

Sea Level Stakes for the Caribbean, in Pictures

Long-term sea level rise set in motion by near-term carbon emissions threatens major coastal cities across the world. Science-based imagery helps show the stakes for the Caribbean. The first image in each pair below shows projections of post-2100 sea level rise that could be locked in following 4°C (7.2°F) of warming from carbon pollution. This … Read More

The 10 Most Important U.S. Climate Stories in 2017

The 10 Most Important U.S. Climate Stories in 2017

Following a year of weather extremes, disasters and policy clashes, we asked our readers to help us pick out the most important climate stories from the U.S. in 2017. This was a brutal year for hurricanes in the U.S. A trifecta of storms (Harvey, Irma and Maria) battered Florida, the Gulf Coast and Puerto Rico, causing deaths and widespread … Read More

Antarctic Modeling Pushes Up Sea-Level Rise Projections

Antarctic Modeling Pushes Up Sea-Level Rise Projections

Antarctic ice sheet models double the sea-level rise expected this century if global emissions of heat-trapping pollution remain high, according to a new study led by Dr. Robert Kopp of Rutgers University and co-authored by scientists at Climate Central. Global average sea level is expected to rise by one foot between 2000 and 2050 and by several… Read More

How Smoke From California’s Fires is Harming the Most Vulnerable

How Smoke From California’s Fires is Harming the Most Vulnerable

David Ewing wore a bright white dust mask, his face behind it puffy and red, as he sat on a stone bench in downtown Santa Barbara, California. A fine layer of ash covered the pavement at his feet, dirty residue from wildfires ravaging the region. “When I woke up yesterday I couldn't breathe,” said Ewing, who is homeless and has been diagnosed with… Read More
