Despite our recent weather bombs, we're experiencing less extreme weather and temperatures than the global average. High temperatures in the Arctic ultimately impact the entire planet.

May 2026: The second: National climate change risk assessment report published

While reading the report keep in mind that the National-led Government gave itself the power to exempt parts of the country from any or all of the Resource Management Act requirements, scrapped positive actions to reduce emissions – ignoring both the MfE ‘Our atmosphere and climate’ report and the Climate Change Commission’s 2023 report. And it’s also working to open conservation lands to mining, drill for oil and gas in the ocean, and build an LNG terminal

The government of New Zealand has been labelled a “disgrace” after it released a new climate plan which barely requires it to reduce emissions between 2030 and 2035. Climate Change News 2025

In July 2025, the Ministry for the Environment released: A proposed approach for New Zealand’s adaptation framework

The government won’t be able to keep bailing out flooded homeowners.   – PM Christopher Luxon: Radio NZ, 09 July 2025

Instructions for interactive graph (Credit: The 2°Institute.)

  • Mouse over anywhere on the graph to see the changes over the last thousand years.
  • To see time periods of your choice, hold your mouse button down on one section then drag the mouse across a few years, then release it.
  • To see how this compares to the past 800,000 years, click on the ‘time’ icon on the top left.
  • To return the graphs to their original position, double-click the time icon.
  • The annual ups and downs in the graph are because plants accumulate carbon in the spring and summer and release some back to the air in autumn and winter. As the northern hemisphere has more land and more plants, carbon dioxide levels go up in winter because plants become less productive. Annual measurements of carbon dioxide are an average of these ups and downs.
