UN Floats Plan to Boost Renewables as Climate Worries Mount

The United Nations chief on Wednesday launched a five-point plan to jump-start broader use of renewable energies, hoping to revive world attention on climate change as the U.N.’s weather agency said greenhouse gas concentrations, ocean heat, sea-level rise, and ocean acidification reached record highs last year.

“We must end fossil fuel pollution and accelerate the renewable energy transition before we incinerate our only home,” U.N. Secretary-General Antonio Guterres said. “Time is running out.”

La Niña Expected Through Spring, Brings Uncertainty to Sierra Snowpack

The recent dry weather in Northern California might be sticking around for a while.

The Climate Prediction Center forecasts a 77% chance La Niña conditions will continue through the month of May.

The term La Niña refers to a correlation between ocean water temperatures and winter weather patterns.

Oftentimes, the weather event brings wetter than normal conditions to the Pacific Northwest and drier weather to Southern California.

California’s Climate Whiplash Has Gotten Worse Over 50 Years

While dry events in California are not getting drier, extreme wet weather events have steadily increased in magnitude since the middle of the last century, new research shows.

These increased extreme wet events can result in more dangerous flooding and also fuel wildfires.

“Most research after 2015 has been very focused on this climate variability and how it’s going to get worse in the future,” says Diana Zamora-Reyes, a graduate student in the department of hydrology and atmospheric sciences at the University of Arizona and lead author of the paper in the International Journal of Climatology.

People Haven’t Just Made the Planet Hotter. We’ve Changed the Way It Rains.

You probably noticed a lot of weird weather in 2021.

From record-breaking deluges and tropical storms to drought-stricken landscapes that erupted in wildfire, the nation seemed to lurch from one weather-related disaster to the next.

You’re forgiven if you dismiss these events as unrelated, albeit unfortunate, phenomena. But they actually share a common bond – they’re all part of a new climate reality where supersized rainfalls and lengthening droughts have become the norm.

Danger in Droughtsville: California’s Urban Water at Risk

Droughtsville, California, is in trouble.

Its water supply is endangered as multiple crises intensify: worsening droughts, competition for scarce supplies, sea level rise, groundwater contamination, earthquakes, wildfires and extreme weather. All of these factors, and more, threaten Droughtville’s ability to provide clean water to its residents.

The city is fictional, but the threats are not.

From Killer Heatwaves to Floods, Climate Change Worsened Weather Extremes in 2021

Extreme weather events in 2021 shattered records around the globe. Hundreds died in storms and heatwaves. Farmers struggled with drought, and in some cases with locust plagues. Wildfires set new records for carbon emissions, while swallowing forests, towns and homes.

Many of these events were exacerbated by climate change. Scientists say there are more to come – and worse – as the Earth’s atmosphere continues to warm through the next decade and beyond.

White House Launches Climate Initiatives to Arm Communities Against Floods, Extreme Weather

The White House announced Tuesday that it would work to revise building standards for flood-prone communities across the country in the face of climate change, while launching tools to make climate information more accessible to the public.

The move is part of the Biden administration’s broader effort to push the United States to reckon with the costs of global warming by factoring in the long-term consequences of decisions being made today.

Opinion: Climate Change Is Bankrupting California’s Ecosystems

For decades, scientists have warned that climate change would disrupt almost every natural life-sustaining system on our planet. What have we done about it? We’ve dithered. We refuse to believe the evidence, or rail against the cost and inconvenience of change, or hope the problem will just go away. But global warming is not going away. Last month, the Intergovernmental Panel on Climate Change issued its most alarming report yet: Earth is on the edge of ecological bankruptcy.

These Maps Tell the Story of Two Americas: One Parched, One Soaked

In New York City, a tropical storm delivered record-breaking rains this weekend. Heavy downpours caused devastating flash floods in central Tennessee, tearing apart houses and killing more than 20 people. Yet, California and much of the West remained in the deepest drought in at least two decades, the product of a long-term precipitation shortfall and temperatures that are much hotter than usual.

This divide, a wetter East and a drier West, reflects a broader pattern observed in the United States in recent decades.

California Faces Unprecedented Dangers as Record Heat, Dryness Combine With Fierce Winds

With more than a million acres burned fairly early in the fire season, California is entering uncharted territory as the record dry conditions that have fueled so much destruction will soon combine with seasonal winds that fire officials fear will bring unprecedented dangers.

Officials have attributed warming temperatures and worsening drought to the explosive growth of fires, mostly in the mountains of Northern California, this summer.
