A Global Milestone: CO2 Passes 400 PPM

A Global Milestone: CO2 Passes 400 PPM

Another month, another carbon dioxide record. This time the record extends beyond the rocky slopes of Mauna Loa, Hawaii, home to the most storied carbon dioxide record, and includes 39 other sites around the globe to paint a troubling picture of a greenhouse gas rise with no signs of slowing down. For the first time since record keeping began … Read More

Climate Change Will Greatly Impact Australians’ Health

Climate Change Will Greatly Impact Australians’ Health

Climate change will have significant repercussions for Australians’ health as warming temperatures fuel extreme weather events, help spread disease and disrupt food and water supplies, according to a report backed by the country’s peak scientific and medical bodies. The report, released by the Australian Academy of Science, warns that vulnerable… Read More

Global Warming Could Threaten 1-in-6 Species

Global Warming Could Threaten 1-in-6 Species

Cranking up the planetary heat is going to ratchet down the planet’s biodiversity, and new analysis suggests global warming will directly threaten one in six species with extinction if polluting practices continue unabated — up from about 3 percent today. Scientists estimated in the journal Nature in early 2014 that climate change could drive … Read More

U.S. Emissions, Economic Growth Headed Toward Divorce

U.S. Emissions, Economic Growth Headed Toward Divorce

Call them a couple: The U.S. economy and energy consumption, along with the greenhouse gas emissions they create, have always grown and plunged together. But as the U.S. embraces energy efficiency and renewables, those things aren’t dancing to quite the same beat anymore. In fact, they’re “decoupling,” and could be heading toward a divorce.… Read More

Blooming Algae Could Accelerate Arctic Warming

Blooming Algae Could Accelerate Arctic Warming

Scientists already know that receding sea ice allows solar energy to warm exposed water rather than reflect back into space, but blooms of algae could make matters even worse. By the end of the century, researchers say, the blooms could lead Arctic warming to increase by as much as 20 percent.… Read More

Extreme Heat and Heavy Rain Events Expected to Double

Extreme Heat and Heavy Rain Events Expected to Double

Extreme weather events such as droughts, heat waves and torrential rainfalls are the most powerful and obvious reminders that the climate is changing. These disasters were happening long before humans started pumping heat-trapping greenhouse gases into the atmosphere, but global warming has tipped the odds in their favor. A devastating heat wave … Read More

At $24 Trillion, Oceans are World’s 7th-Largest Economy

At $24 Trillion, Oceans are World’s 7th-Largest Economy

The monetary value of the world’s oceans has been estimated at $24 trillion in a new report that warns that overfishing, pollution and climate change are putting an unprecedented strain upon marine ecosystems. The report, commissioned by WWF, states the asset value of oceans is $24 trillion and values the annual “goods and services” it provides, … Read More

Look What’s Cooking in the World of Renewable Energy

Look What’s Cooking in the World of Renewable Energy

Inside a sprawling single-story office building in Bedford, Mass., in a secret room known as the Growth Hall, the future of solar power is cooking at more than 2,500 °F. Behind closed doors and downturned blinds, custom-built ovens with ambitious names like “Fearless” and “Intrepid” are helping to perfect a new technique of making silicon wafers, t… Read More
