It has become common to lament the public crisis of trust in science, experts, and institutions, but much of the decline in trust is deserving. When the public senses that researchers and academic journals are attempting to leverage their scientific authority to advance particular political goals, it ironically undermines that very authority. But we need researchers and academic journals to help inform (but not dictate) critical societal decisions. Scientific institutions just must earn back the public’s trust by demonstrating intellectual humility, a disinterest in how results come out, and by showing that they are open to a wide diversity of opinion and vigorous debate on contested topics.

- from the claim that "Valley Fever" now threatens California because it has started to have weather
- to the claim that the Arctic will soon be ice-free unless it's not, this time for sure,
- a vote against the Anthropocene, B.C. having constant heatwaves unless it doesn't,
- plus the loose definition of "heatwave",
- 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.

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.

Contrary to claims by many climate activists and politicians, extreme weather events — including forest fires, droughts, floods, and hurricanes — are not increasing in frequency or intensity.
A new study published by the Fraser Institute today finds that global temperatures have increased moderately since 1950 – but there is no evidence that extreme weather events are on the rise:
- Droughts: Data from the World Meteorological Organization Standardized Precipitation Index showed no statistically significant trends in drought duration or magnitude.
- Flooding: Research in the Journal of Hydrology in 2017, analyzing 9,213 recording stations around the world, found there were more stations exhibiting significant decreasing trends (in flood risk) than increasing trends.
- Hurricanes: Research conducted for the World Meteorological Organization in 2019 (updated in 2023) found no long-term trends in hurricanes or major hurricanes recorded globally going back to 1980.
- Forest Fires: In Canada, data from Canada’s Wildland Fire Information System show that the number of fires and the area burned in Canada have both been declining over the past 30 years.
Governments need to study the actual data and base their actions on facts, notunsubstantiated claims.
