Berkeley Earth now has monthly temperature records for thousands of cities. Here's how summer has changed in Auckland, New Zealand - average max are up 2.1 ÂșC, from 21.6 to 23.7 ÂșC. More than half (+1.1 ÂșC) of that increase occurred in the past 20 years, a warming rate of 0.55 ÂșC per decade.

A sunny day in winter can generate as much solar power as an average day in summer. (Not quite a fair comparison as capacity is up ~20% â still impressive though.) Graph (
app.em6.co.nz
) shows daily NZ utility solar power generation in MWh. 1000 MWh is enough to make about 30 million cups of tea.

New Zealand energy emissions to March 2026: slow decline continues due to falls in coal, gas (running out), and electricity (wet weather + more RE). These are all small sources â oil is >75% of emissions and has increased in each of the past 5 years (even though data includes 1st month of the war).

The requirement for an Energy Strategy is still part of the Emissions Reduction Plan. The Government said late last year that the requirement to consult on changes to the ERP would be scrapped in a new amendment to the Climate Change Response Act in 2026 but I don't think that has happened yet.

No country is too small to matter. Nations that each emit around 1% of global CO2 may look negligible on their own, but together they produce about 30% of the total â roughly as much as China. If they sit it out, the maths doesnât stack up.
