Articles tagged with "co2"

For my discussion this week I will consider two articles, one of which is the good news and the other the bad news.

This is a review of “The alarmist: fifty years measuring climate change”, by Dave Lowe, Victoria University press 2021.

In a recent newsletter, from Monday 24th November 2025, Mark featured an item about levels of CO2 in the atmosphere which was contributed by Mike Kearsley. Mr Kearsley sounds like he's been swayed by various sources of climate change disinformation. Mike asked us to specify what the optimum level of CO2 in the atmosphere should be.

I am writing in the hope that my current confusion might be cleared up by the membership of the NZ Skeptics. This concerns climate change, and more specifically the need to reduce carbon emissions – the level of CO2 in the atmosphere.

Patrick Medlicott published a piece in our last newsletter about a talk on New Zealand's response to climate change - about what we're currently doing, and what we should be doing. One of our newsletter subscribers, Mike, reached out to me after he received the newsletter, expressing his confusion about the article:

Last weekend saw the release of a new policy by the government called the Clean Car Discount.

Brian Cox argued with Australian senator Malcolm Roberts on TV show Q&A about climate change, accusing NASA and other organisations of "corrupting" temperature data.
