Humanity heating planet faster than ever before, study finds Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El NiΓ±o

The Guardian on our new study, which shows that global heating is significantly gathering speed. Our efforts to overcome our fossil fuel addiction should do the same.

Global map showing sea surface temperature anomalies in February 2026 relative to 1982 to 2010. Most areas are warmer than average. Red is shown for warmer sea surface temperatures, and blue is shown for colder sea surface temperatures. Data is from NOAA OISSTv2.1.

Sea surface temperatures continue to show large departures (red shading) across the midlatitudes of both hemispheres through February 2026. Note also the recent warming across the eastern tropical Pacific (especially NiΓ±o 1+2 regions).

BREAKING
It’s been revealed that the Luxon government β€˜kicked the tyres’ on game-changing solar subsidies to cut power bills but decided to let us keep paying rising prices - and then to make it even worse with costly gas imports:

A new space race could turn our atmosphere into a β€˜crematorium for satellites’ Planned β€˜megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

"Rocket launches already contribute to climate change and ozone depletion. Scaling them up to deploy a million aircraft-sized satellites would push upper-atmosphere heating and ozone loss far beyond previous estimates, with the steady burn-up of dead satellites compounding the impacts." πŸ§ͺπŸ›°οΈπŸš€

Government deciding whether US should get access to New Zealanders' biometric data Officials are in talks with the US about a new travel deal.

As the chair of @nzccl.org.nz said,

"We wouldn't give other countries like China or Russia full access into our police and biometrics databases, would we?"

Absolutely disgusting that this is being contemplated, let alone that it might be decided without Parliament.

Line graph time series of 2026's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2025. 2026 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and March by looking at the decadal average line positions.

There's been this hit job on the Green Party by ACT's NZCPR, claiming money was "stolen" from water infrastructure for cycleways.

In fact, their Council invested significantly, more than others over decades.

They put $2.7 billion to 3W in 2021 and 1.8% of that on cycleways #nzpol

By defeating seabed mining in Taranaki, the green movement has created the option of large scale, low carbon, reliable, cheap offshore wind, which will actually make a real difference to NZ’s energy system. Unlike an LNG import facility which is expensive, polluting and small.

In total over four years, through both the mini Budget and Budget 2024, the government has redirected $2.4 billion in previously ring-fenced climate spending into other spending - although several climate programmes have survived, under different funding streams.

The government gave itself more money to play with by taking money from the Climate Emergency Response fund (CERF), which took money raised from selling carbon credits to polluters under the Emissions Trading Scheme and put it into climate-related projects.

*That money has now been redistributed to general spending*, although some of the projects CERF funded are continuing.

The govt made a deliberate choice to fund tax cuts for landlords, corporates and the wealthy instead of health, climate and public services.
