With Tree Rings On Their Fingers
There's a lot of apparently confident talk about how current temperatures compare with those in the past, including claims of 2023 being the "hottest year ever" or at least in the last 125,000. But how do we actually know, and how much do we actually know, about historic and prehistoric temperatures? In this Climate Discussion Nexus "Backgrounder" video John Robson examines the uses, and abuses, of various temperature proxies.

How Feverish Was My Valley?
Dr. John Robson comments on key items from the latest Climate Discussion Nexus weekly "Wednesday Wakeup" newsletter (https://climatediscussionnexus.com/ne..., from the claim that "Valley Fever" now threatens California because it has started to have weather to the clami that the Arctic will soon be ice-free unless it's not, a proposal simply to ban fossil fuels and be done with it, and everything else, a computer model saying Arctic ice will slow down which is bad as was it speeding up, John Kerry finally stepping down as futile climate envoy, China dominating storage batteries too, a #Gettingworse instalment debunking extreme weather damage worldwide getting worse, a devastating finding that the "hockey stick" is an artefact, and more evidence that the Holocene Climatic Optimum was "optimum" because it was warm.

Climate Shipwreck
Dr. John Robson comments on key items from the latest Climate Discussion Nexus weekly "Wednesday Wakeup" newsletter (https://climatediscussionnexus.com/ne..., starting with the claim that Franklin's ships sunk in the Canadian Arctic are vulnerable to climate change, followed by a study saying that because Antarctica warmed naturally thousands of years ago humans must be doing it now, warnings of the end of fancy food due to climate change, a #Gettingworse instalment debunking extreme weather in Europe, the margin of measurement error exceeding the supposed energy imbalance in the atmosphere, and more on atmospheric blocking.

When Backroom Met Zealot
In this "Fact Check" video from the Climate Discussion Nexus, Dr. John Robson debunks a stream of ignorance and misinformation directed at Ottawa City Council over fossil fuel ads, and warns that wherever you live, these kinds of meetings are going on with little or no scrutiny or diversity of opinion.

A Parasol For Planet Earth
Dr. John Robson comments on key items from the latest Climate Discussion Nexus weekly "Wednesday Wakeup" newsletter (https://climatediscussionnexus.com/ne..., starting with the bizarre geoengineering idea of putting an umbrella in space to fend of the sun's rays and hope they don't miscalculate, and moving on to journalists who can't believe anyone disagrees with them on climate,Canada's carbon tax causing energy poverty, more global greening due to rising CO2, a sudden enthusiasm for "green hydrogen", someone saying spending $266 trillion on climate policy is a "no-brainer", a #Gettingworse instalment showing that floods aren't, and a study of Caribbean sediments showing nearly a thousand years of, yes, dramatic natural climate change.
