Phytoplankton, reducing greenhouse gases or amplifying Arctic warming?

Phytoplankton, commonly known as plant plankton that remove carbon dioxide from the atmosphere through photosynthesis, are potentially a key driver of Arctic warming under greenhouse warming, a study reveals. Scientists with Pohang University of Science and Technology (POSTECH), Max Planck Institute for Meteorology (MPI-M), and Korea Institute of Ocean Science and Technology (KIOST), presented on Monday, April 20, in Proceedings of …

Economic Collapse Will Limit Climate Change, Predicts Climate Scientist – Till Bruckner

If you think your doctor is hard to understand, try talking to a climate scientist. In late 2014, the World Bank published a remarkable document that should have shaken the international business world. Titled “Turn Down the Heat: Confronting the New Climate Normal“, it drew on 1,300 publications to explore the impacts of a world four degrees centigrade warmer – …

Carbon Sequestration Is Not A Solution To The Climate Crisis

Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be for the very long term, thousands of years. Now, a team in Brazil, writing in the International Journal of Global Warming has reviewed the risk assessments …

Food, Farming and Climate Change: It’s Bigger than Everything Else – Ryan Zinn

Record-breaking heat waves, long-term drought, “100-year floods” in consecutive years, and increasingly extreme superstorms are becoming the new normal. The planet is now facing an unprecedented era of accelerating and intensifying global climate change, with negative impacts already being widely felt. While global climate change will impact nearly everyone and everything, the greatest impact is already being felt by farmers …

Permafrost holds key to release of trapped carbon – Tim Radford

Three sets of scientists in the same week have helped narrow the uncertainties about how the natural world will respond to extra carbon dioxide in the atmosphere caused by the burning of fossil fuels. Carbon locked in the frozen earth will escape gradually as the Arctic permafrost melts – but the scientists say the process could accelerate. As greenhouse gas …

Scientists predict gradual, prolonged permafrost greenhouse gas emissions, allowing us more time to adapt

A new scientific synthesis suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions, which may afford society more time to adapt to environmental changes, say scientists in an April 9 paper published in Nature. “Twenty years ago there was very little research about the possible rate of permafrost carbon release,” said co-author A. …

Anesthetic gases raise Earth’s temperature (a little) while you sleep

The gases used to knock out surgery patients are accumulating in the Earth’s atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield as Antarctica. Over the past decade, concentrations of the anesthetics desflurane, isoflurane and sevoflurane have been rising globally, the new study finds. Like the well-known climate warmer …

Global-Warming-3845

The price to be paid for not cutting emissions of greenhouse gases could mean driving the planet across planetary boundaries, or “tipping points”.

An international team of scientists has tried a new approach to addressing the complex argument about the costs of climate change – and, once again, the prediction is that the costs of inaction will be so much greater than paying the bills now. The researchers − from the UK, Switzerland and the US − conclude that policy-makers must apply the …

Is the Earth a Sentient Being?

A world renowned biologist told me over breakfast one morning that great scientific advances do not begin with moments of sudden insight that elicit “Eureka,”  but with moments of puzzlement that produce a…..”Huh?” In other words, things that suddenly make sense are less likely to revolutionize the way we look at the world than things that make no sense. Discoveries that make sense …

A “Climate Movement Across the Movements”

Looming ahead in eight months’ time is another Conference of Polluters, or COP (technically, the Conference of the Parties to the United Nations Framework Convention on Climate Change). The last twenty did zilch to save us from climate catastrophe. Judging by early rough drafts of the Paris COP21 agreement recently leaked, another UN fiasco is inevitable. The ‘Coalition Climat21’ strategy …
