The forest fire feedback, Yellowstone’s case: ecosystem shift by 2050

Climate change could cause the forests of the world’s oldest national park, Yellowstone, in the Eastern Rocky Mountains, to shift to a gras and shrub ecosystem, US scientists warn. It could happen in four decades, and will likely not be … Continue reading →

Triassic-Jurassic mass extinction caused by >16,000 Gt methane – from clathrates

Scientists of Utrecht University have investigated fossil leaves found in terrestrial late Triassic sediments and discovered a large carbon-13 depletion. That means 200,000,000 years ago The Methane Bomb went off.

Soils don´t need warming to add another positive climate feedback

We recently reported on a possible negative carbon feedback of forest soils in higher latitudes: when such soils warm, nutrient availability may increase, as would (therefore) biomass production and CO2 uptake. But not all climate feedbacks operate through temperature. It … Continue reading →

First proof ocean CO2 uptake has started to slow down

From raw measurements we know that in recent years the oceans seem to take up a smaller percentage of the CO2 we emit. Analysing available data a group of three researchers finds in part of the North Atlantic this is … Continue reading →

Antarctic krill promotes CO2 uptake by plankton through iron fertilisation

Iron is very rare in the upper layers of the world´s oceans, where photosynthesis is possible and therefore biological activity and concentration of living biomass is highest, making the mineral a growth-limiting nutrient in 40 percent of the world’s oceans, … Continue reading →

Another forest study points to negative climate feedback

And this one may really present some good news for the climate, as it isn’t a Petri dish case, but very much in vivo. But don’t get overexcited. A group of Finnish researchers studied forest sites in 68 nations and … Continue reading →

Current CO2 rise 10 times as fast as PETM climate disaster

For the layman paleoclimatology is ‘proof’ that any climate change is natural. For educated thinkers the lessons from the long ago contain the biggest warnings for the current artificially created state of our planet.

No evidence bacteria ate methane at end of Snowball Earth

Same story as yesterday, but now 635 million years earlier. This time again no evidence can be found that it were microbes that ate climate-disrupting amounts of methane, at the end of the Marinoan ice age, better known as ‘Snowball … Continue reading →
