Global Wind Speeds: are they falling due to climate change?

October 14, 2022 by Jim Robbins

Last year, Europe experienced a “wind drought”, with wind speeds falling 15% in many regions, sometimes more. Deeper research shows speeds dropped gradually between 1978 and 2010, though rose again in the last decade. It’s difficult for the science to create a clear picture and predict long term trends. But the IPCC forecasts slowing winds for the coming decades, saying average annual wind speeds could drop by up to 10% by 2100. Jim Robbins at … [Read more...]

Climate tipping points: what the science tells us about runaway devastating changes

October 11, 2022 by David Armstrong McKay

It would be helpful if the science of climate tipping points gave clear answers to what temperature rise will trigger a runaway catastrophe: knowing that temperature rise X will cause calamity Y should focus everyone’s minds to do the right thing. But there’s simply not enough data for the science to do that, though it is clear that destabilisation is underway and major tipping points are approaching. That means we are in the danger zone, says … [Read more...]

COP26 accepted the science like never before. It should make a difference

December 1, 2021 by Sonia Seneviratne, Maisa Rojas, Pep Canadell, Christophe Cassou, Piers Forster, Nana Klutse, June-Yi Lee and Joeri Rogelj

Leading scientists, writing for Carbon Brief, explain how COP26 gave far greater recognition to science than any of the previous COPs. The scientific evidence from the latest IPCC reports was explicitly acknowledged in the Glasgow Climate Pact. That is a significant advance, say the authors. Decision-making guided by science can focus quantitively on carbon budgets, temperatures, climate change, the causes, and therefore the emissions-reductions … [Read more...]

Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?

October 13, 2021 by Rob Jordan

If you think CO2 removal isn’t getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [Read more...]

How multi-scenario ‘emulator’ models are improving climate change projections

October 1, 2021 by Chris Smith

State-of-the-art Earth System Models (ESMs) simulate the flow of energy, moisture and chemicals through the atmosphere, ocean and land surface in unprecedented detail. But the data processing is so demanding that each scenario takes considerable time and expense to run, needing powerful supercomputers and teams of scientists and programmers to produce the models and analyse the results. “Emulators” are much simpler models that can run on a … [Read more...]

Cement: replacing limestone with volcanic rock could slash energy use, and emissions by two-thirds

June 30, 2021 by Josie Garthwaite

Cement production accounts for 8% of global emissions, and it will rise as nations get richer and build more. It’s mainly because of the energy needed for the high heat process, and the carbon released from the limestone used. It’s one of the leading hard-to-abate sectors, and coming up with an alternative process and cement recipe is firmly on the industry’s agenda. Josie Garthwaite at Stanford University summarises a study that aims to replace … [Read more...]
