A vibrant Native-American agrarian culture stretched from the Ohio River Valley to the Mississippi River Valley in the two centuries before Europeans settled in North America. Then it disappeared.
Following a campaign by the coal industry, Prime Minister Malcolm Turnbull has argued for new coal-fired power stations in Australia. But these plants would be more expensive than renewables and carry a huge liability through the carbon emissions they produce.
Last year we found that the growth in global fossil fuel emissions have stalled over the past three years.
There is huge potential for using electric vehicles to tackle climate change, give us cleaner air and grow the green economy.

Australia is a huge continent, but a coastal nation. About 80% of Australians live within 50km of the coast, and a sea-level rise of 1.1 metres (a high-end scenario for 2100) would put about A$63 billion (in 2008 dollars) worth of residential buildings at risk.

Methane concentrations in the atmosphere are growing faster than any time in the past 20 years. The increase is largely driven by the growth in food production, according to the Global Methane Budget released today.
For a period about a million years ago Greenland wasn’t covered in ice. Researchers say the discovery suggests it’s possible the ice sheet could go away again.
You probably don’t think clams are the most exciting animals on the planet. But anyone who dismisses these marine bivalve molluscs surely cannot be aware of just how important they actually are. Without knowing it, they have taught us so much about the world we live in – and how it used to be.
Detroit-area resident Shamayim Harris bought more than 10 properties on her block. She’s now converting them into sustainable community spaces for education, wellness, and economic development.

A new theoretical model may lead to timelier, accurate forecasts of the central Pacific El Niño, an important weather-maker. Any El Niño is a period of warmer-than-normal sea-surface temperature in the equatorial Pacific.
The consequences of climate change are already being felt all over the globe. But some regions are particularly affected. These so-called “hotspots” are areas where strong physical and ecological effects of climate change come together with large numbers of vulnerable and poor people and communities.
Will President Trump really slash funding of NASA’s “politicized” climate change science?

The election of Donald Trump as president of the United States is bad news for the global environment. He has made it clear that he will not implement the steps required to meet the pledges to reduce emissions as part of the agreement reached in Paris at the end of 2015.
US scientists think the effect clouds have on global warming may be underestimated. New research shows that clouds block sunlight and reflect radiation back to space, impeding the rate of global warming. But for how long?
The high ambition of the Paris Agreement, to limit global warming to “well below 2°C”, was driven by concern over long-term sea level rise. A warmer climate inevitably means melting ice – you don’t need a computer model to predict this, it is simple common sense.

NOAA’s National Centers for Environmental Information (and several other institutions) reported April 2016 to be the warmest April on record for the planet. All of the previous twelve months now hold the “Warmest [INSERT MONTH HERE] on Record” title. That’s twelve months in a row, and that’s never happened.
Bolivia’s glaciers have shrunk by more than 40% in the past few decades. This puts further pressure on an already stressed water supply, while the meltwater lakes left behind risk collapsing in sudden and catastrophic outburst floods.
Educating rural communities can help them prevent permanent damage to the environment. There is a common misconception that you can’t talk about climate change in rural communities because the issue is considered too polarizing...

New study finds that man-made global warming is the root cause of a relentless increase in forest fires in the US.
Ever since the 1973 oil embargo, U.S. energy policy has sought to replace petroleum-based transportation fuels with alternatives. One prominent option is using biofuels, such as ethanol in place of gasoline and biodiesel instead of ordinary diesel.
In this presidential election year we have heard much about some issues, such as immigration and trade, and less about others.
The unprecedented West Coast toxic algal bloom of 2015 appears to be linked to the unusually warm ocean conditions—nicknamed “the blob”—in the winter and spring of that year.

The Aliso Canyon leak in California earlier this year focused public attention on methane emissions from the oil and gas industry.
Six years ago, Phoenix lay burning in the sun one day. It was 110 degrees Fahrenheit and I was the only person foolish enough to be out walking instead of moving by air-conditioned car. Arriving hot and parched at a bookstore, I opened the doors to be greeted by a blast of arctic air.
As global warming cuts crop yields, trade liberalisation in agricultural commodities will be needed to avoid food shortages and economic hardships.
