This week’s decision by four Australian Catholic orders to divest fully from fossil fuels can be interpreted as a direct response to the encyclical on the environment, issued by Pope Francis almost exactly a year ago.

The fossil fuel industry has spent many millions of dollars on confusing the public about climate change. But the role of vested interests in climate science denial is only half the picture.

The solar panels of about 40,000 Massachusetts households and community groups cut electricity prices for all of the approximately three million electricity ratepayers in the state, even those without the panels, also called photovoltaics (PV) systems.

Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study offers the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Arctic amplification.

On May 19, India’s all-time temperature record was smashed in the northern city of Phalodi in the state of Rajasthan. Temperatures soared to 51?, beating the previous record set in 1956 by 0.4?.

Squid, octopus and cuttlefish populations are booming across the world. These fast-growing, adaptable creatures are perfectly equipped to exploit the gaps left by extreme climate changes and overfishing, according to a study colleagues and I published in the journal Current Biology.

The plan for Louisville includes tree-planting targets and cool roofing and paving goals for different neighborhoods. In all, an additional 450,000 trees are recommended.

Sea-level rise, erosion and coastal flooding are some of the greatest challenges facing humanity from climate change.

Battery costs are plummeting to levels that make EVs a truly disruptive technology, as we’ve explained. That’s why electric vehicle (EV) sales are exploding world-wide, and why Tesla broke every record for pre-sales with its affordable ($35,000), 200+ mile range Model 3 last month.

Among climate change activists, solutions usually center on a transition to renewable energy. There may be differences over whether this would be best accomplished by a carbon tax, bigger subsidies for wind and solar power, divestment from fossil fuel companies

Global demand for energy is increasing by the hour as developing countries move toward industrialization. Experts estimate that by the year 2050, worldwide demand for electricity may reach 30 terawatts (TW). For perspective, one terawatt is roughly equal to the power of 1.3 billion horses.

A team of marine scientists has returned from nearly a month of scuba diving on coral reefs in the middle of the equatorial Pacific Ocean. What they saw will haunt them for a long time.

Marine life faces increased threats as researchers warn that warmer waters caused by climate change could seriously reduce the levels of oxygen in the world’s seas.

"Weather patterns in recent decades have been a poor source of motivation for Americans to demand policies to combat the climate change problem," says Megan Mullin. "But without serious efforts to reduce greenhouse gas emissions, year-round climates ultimately will become much less pleasant."

One of the places machine learning is turning out to be the most beneficial is in the environmental sciences, which have generated huge amounts of information from monitoring Earth’s various systems — underground aquifers, the warming climate or animal migration, for example.

Much of the U.S. was built around the automobile, with greater distances to be covered than in places like Europe, making Americans' daily lifestyles higher in energy than elsewhere.

The National Renewable Energy Laboratory this week said that rooftop solar panels have the potential to generate nearly 40 percent of electricity in the U.S. But what about the cost of going solar?
