Scientists from the Deep Carbon Observatory (DCO) project have spent 10 years assessing the "reservoirs and fluxes" of the chemical element. In other words, they worked out where carbon is held and in what form, and how it moves through the Earth system.

Climate change being fuelled by soil damage - report

There's three times more carbon in the soil than in the atmosphere – but that carbon's being released by deforestation and poor farming. This is fuelling climate change – and compromising our attempts to feed a growing world population, the authors will say. Problems include soils being eroded, compacted by machinery, built over, or harmed by over-watering.

When bogs burn, the environment takes a hit. In 2015, massive wildfires burned through Indonesia, sending thick smoke and haze as far as Thailand.

When bogs burn, the environment takes a hit

These fires were “the worst environmental disaster in modern history,” says Thomas Smith, a wildfire expert at King’s College London. Smith estimates that the fires and smoke killed 100,000 people in Indonesia and neighboring countries and caused billions of dollars in damage. The fires were costly for the rest of the planet, too: At their peak, the blazes belched more climate-warming carbon dioxide into the atmosphere each day than did all U.S. economic activity. Two years later and 13,000 kilometers away, a fire smoldered on the fringes of a barren, northern landscape. Have you heard of the 'Little Ice Age'?

Perhaps it’s because most of us have seen them – and on occasion, fallen into them – and think they’re only good for goldfish. Ponds may be the number one habitat for children’s “minibeast” hunts, but we are supposed to grow out of them in adulthood. As James Clegg, a 20th-century British naturalist wrote, ponds are a field particularly suited to the activities of the amateur, whose humble pond-hunting, if carried out systematically and carefully, may well result in valuable contributions to science. #LifeOnEarth is dominate by plants making up 82% by weight.

European colonisation of the Americas killed 10% of world population and caused global cooling. While Europe was in the early days of the Renaissance, there were empires in the Americas sustaining more than 60m people.

European colonisation of the Americas killed 10% of world population and caused global cooling

But the first European contact in 1492 brought diseases to the Americas which devastated the native population and the resultant collapse of farming in the Americas was so significant that it may have even cooled the global climate. The number of people living in North, Central and South America when Columbus arrived is a question that researchers have been trying to answer for decades. Unlike in Europe and China, no records on the size of indigenous societies in the Americas before 1492 are preserved.

To reconstruct population numbers, researchers rely on the first accounts from European eyewitnesses and, in records from after colonial rule was established, tribute payments known as “encomiendas”.

Scottish lochs 'important stores' of carbon

Using samples from Loch Etive, near Oban, researchers calculated that a square metre of sediment contains more carbon than peatlands. Protecting carbon stores is important because when it is disturbed it can release greenhouse gases. The study was carried out by researchers at St Andrews University. While millions is spent on enhancing and restoring carbon-stores in peat moors, sea lochs are afforded relatively little protection from activities like dredging and the researchers said that needed to change. Research fellow Craig Smeaton said: "Scottish sea lochs contain a large amount of carbon. Enquiry Qs broken down into Spec requirements and then a possible exam Q to assess students on their k&u.

One of the biggest environmental disasters in US history is happening right now, and you've probably never heard of it.

An enormous amount of harmful methane gas is currently erupting from an energy facility in Aliso Canyon, California, at a startling rate of 110,000 pounds per hour. The gas, which carries with it the stench of rotting eggs due to the addition of a chemical called mercaptan, has led to the evacuation 1,700 homes so far. Many residents have already filed lawsuits against the company that owns the facility, the Southern California Gas Company.

Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release. Release Date: February 9, 2017 A recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester sheds light on the interactions of gas hydrates and climate. The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as gas hydrate, is a naturally-occurring, ice-like form of methane and water that is stable within a narrow range of pressure and temperature conditions. On a global scale, gas hydrate deposits store enormous amounts of methane at relatively shallow depths, making them particularly susceptible to the changes in temperature that accompany climate change.

*****Permafrost degradation: In Siberia there is a huge crater and it is getting bigger. Near the Yana river basin, in a vast area of permafrost, there is a dramatic tadpole-shaped hole in the ground: the Batagaika crater. The crater is also known as a "megaslump" and it is the largest of its kind: almost 0.6 miles (1km) long and 282ft (86m) deep. But these figures will soon change, because it is growing quickly.
