MisleadingNo evidence for a significant influence of volcanoes or solar variability on recent climate change contrary to Judith Curry’s claims in PragerU video
Claim:
Climate scientists disagree about how much warming is associated with our emissions and whether this warming is larger than natural climate variability from the sun and volcanic eruptions

IncorrectCarbon isotopes do not show that humans’ climate impacts are too small to notice, despite the Daily Sceptic’s inaccurate claim
Claim:
Human-caused carbon emissions’ effect on climate is ‘non-discernible’. Measurements of carbon isotope ratios in atmospheric CO2 indicate that it is the recent expansion of a more productive biosphere that has led to increased CO2 concentrations in the atmosphere.

InaccurateData shows temperatures rising in Greenland and around the world; current global warming is driven by CO2, not solar activity
Claim:
Ice cores from Greenland show no significant warming, casting doubt on the climate change theory

IncorrectArctic sea ice has been melting over the past decades with projections for summer ice-free conditions by mid-century
Claim:
Arctic sea ice is not melting and there is no indication that we should expect the Arctic sea summer ice to disappear completely, as predicted

MisleadingOptimal atmospheric CO2 for dinosaurs and plants is harmful for humans; current concentration is higher than Homo sapiens have ever experienced
Claim:
High CO2 was fine for the dinosaurs and high CO2 benefits plants today in greenhouses, so more CO2 can’t be bad for humans

Of the many factors that cause wildfires, the influence of climate change and human activities is growing
Although there are multiple things at play when it comes to wildfires, climate change is becoming increasingly important. Wildfires are the result of complex interactions between biophysical and human factors, and it only takes one poorly managed campfire to cause a serious, widespread wildfire disaster. Many wildfires are indeed the direct result of human activities. However, many more and much worse wildfires are now possible because of climate change, leading to greater environmental and economic negative impacts.

Authorities undertaking climate action targeted by viral “Climate lockdowns” narrative on social media
The increasing number of measures to limit greenhouse gas pollution that can be expected in the future will certainly present opportunities for future weaponization and misrepresentation. Writers, editors, and journalists should be aware of these manipulation tactics when discussing the aftermath of COVID-19 restrictions or future climate policies, knowing that some actors are trawling for any evidence to boost the manufactured ‘climate lockdown’ outrage.

What’s in a number? The significance of the 1.5°C warming threshold and reporting on its possible breach in popular media
These findings were widely covered by popular media outlets, including in articles published by The Guardian, CNN, and BBC, which all reported that this temperature increase would represent a breach of the key IPCC threshold. However, this is missing some important context.
“A single year above 1.5°C does not mean the world has passed that particular warming level”, said Zeke Hausfather. Such nuance was better captured by articles published in Reuters and Axios, which both correctly did not report that these new temperature projections, if realized, would constitute a breach of the threshold.
