Here’s How Much Arctic Sea Ice Has Melted Since the ‘80s

Here’s How Much Arctic Sea Ice Has Melted Since the ‘80s

Arctic sea ice has been melting at a steady clip this summer as it heads toward its annual low point. But a new chart shows that with nearly two months still left in the melt season, sea ice area is already below what would have been a yearly low in the 1980s. The comparison shows the clear long-term decline of Arctic sea ice fueled by the global … Read More

South Miami Just Made a Huge Rooftop Solar Decision

South Miami Just Made a Huge Rooftop Solar Decision

South Miami this week became the first city outside of California to require all new homes to install solar panels on their roofs. Six cities in the Golden State began requiring solar to be installed on new homes over the past few years. But in Florida, where voters killed proposed solar restrictions last year, South Miami is now a pioneer. This… Read More

The Larsen C Iceberg Is Already Cracking Up

The Larsen C Iceberg Is Already Cracking Up

The trillion-ton iceberg that broke off Antarctica last week will not go quietly into the night. New satellite imagery reveals that the iceberg, dubbed A68, is already shifting shape along with the remaining Larsen C ice shelf itself. The iceberg has traveled about 1.5 miles from the ice shelf it was formerly attached to. A piece of ice the size … Read More

Rising Seas Spark Tobacco-Style Lawsuits in California

Rising Seas Spark Tobacco-Style Lawsuits in California

Several flood-prone municipalities in California filed first-of-their-kind lawsuits against fossil fuel companies this week as they attempt to recoup the cost of coping with rising seas. The suits point to indisputable climate science and decades of industry efforts to mar that science. Experts likened the legal complaints to those brought against… Read More

At Midway Point, 2017 Is 2nd-Hottest Year on Record

At Midway Point, 2017 Is 2nd-Hottest Year on Record

At the halfway point of the year, 2017 remains the second-hottest year to date — a surprise given the demise of the El Niño that helped boost temperatures to record levels last year. The continued near-record warmth is a marker of just how much global temperatures have risen thanks to the greenhouse gases accumulating in the atmosphere from fossil… Read More

Countries With Coral Reefs Must Do More on Climate

Countries With Coral Reefs Must Do More on Climate

Countries with responsibility over world heritage-listed coral reefs should adopt ambitious climate change targets, aiming to cut greenhouse gas emissions to levels that would keep global temperature increases to just 1.5°C, the UN agency responsible for overseeing world heritage sites has said. At a meeting of Unesco’s world heritage committee in… Read More

Today’s Extreme Heat May Become Norm Within a Decade

Today’s Extreme Heat May Become Norm Within a Decade

When 2015 blew the record for hottest year out of the water, it made headlines around the world. But a heat record that was so remarkable only two years ago will be just another year by 2040 at the latest, and possibly as early as 2020, regardless of whether the greenhouse gas emissions warming the planet are curtailed. That is the conclusion of a… Read More

Greenhouse Gases Are Rapidly Changing the Atmosphere

Greenhouse Gases Are Rapidly Changing the Atmosphere

Humanity’s grand experiment in the atmosphere continues, and a new report documents just how far it’s gone. On Tuesday, the National Oceanic and Atmospheric Administration released its annual index of 20 key greenhouse gases. It shows that their direct influence on the climate has risen 140 percent since 1750, with 40 percent of that rise coming… Read More
