Climate Change & Anthropocene Extinction 23: Amazon ‘tipping point’ is a sliding process, from +1C

In this article we try to quantify the Amazon rainforest climate tipping point, based on available scientific literature. We conclude there’s no real basin-wide threshold temperature to activate the forest-killing biome switch. Rather it seems to be a sliding process, … Continue reading →

Real Global Temperature Trend, p17 – Climate System Thermal Inertia is lower when you don’t assume CO2 flatline

Oceans, oceans, oceans. You thought the atmosphere was complex? Well, just take a look at the oceans. Oddly shaped features with disturbing cycles and conveyor belt currents. Home of the octopus, the blue whale and a Mariana Trench full of … Continue reading →

Europe can have warm Gulf Stream and ice age cold peak simultaneously

Judging by new ocean sediment measurements and climate model runs the Atlantic Meridional Overturning Circulation (AMOC) was ‘at least as strong’ during the last ice age’s Last Glacial Maximum as it is today.

Vanished Brazilian Atlantic Forest still has negative carbon balance

Not so long ago Brazil was home to not one, but two of the Earth´s largest tropical rainforest biomes, the Amazon and the Atlantic Forest. Including true rainforest, dry tropical forest and mangroves the Atlantic Forest used to span an … Continue reading →

Photo of the day: the old climate versus the new, according to Nature Geoscience study

The picture below shows Pinyon pine forests in New Mexico – and the progressive consequence of the large drought that hit western North America between 2000-2004. The left image is from 2002 and already shows some browning of pine trees halfway … Continue reading →

Antarctic Carbon Capture and Storage Whirlpools discovered

“The Southern Ocean is a large window by which the atmosphere connects to the interior of the ocean below” – Jean-Baptiste Sallée from British Antarctic Survey, lead author of new publication in the August edition of Nature Geoscience.

Grand Solar Minima do bring cooling to Europe Holocene record shows

But now it’s not dry and icy five-month winters, but wet and windy springs instead. Or would you say these combine?

New source of methane discovered: the Arctic Ocean

It has been know for some time that large quantitites of methane lie hidden in reservoirs under the permafrost layers on the tundra and in clathrates on the continental shelve. It is neither a secret that those large quantities of … Continue reading →

Can medieval volcanic eruptions have caused global cooling when tree rings don’t show?

A group of researchers led by climatologist Michael E. Mann of the Earth System Science Center of Pennsylvania State University says the dendrochronological record does not always offer the best temperature reconstruction. Apparently some trees find it hard to distinguish … Continue reading →
