Earth stays above 1.5°C warming for a year
Earth's average temperature remained 1.5°C above pre-industrial levels for a full year, signaling ongoing and severe climate shifts.
In short:
- Earth's average temperature stayed above 1.5°C for 12 consecutive months, the first such occurrence in recorded history.
- Scientists stress that this 12-month period does not mean the Paris Agreement's 1.5°C limit has been breached, as that target is based on longer-term averages.
- Climate experts warn that, without significant reductions in greenhouse gas emissions, more temperature records will be broken, and long-term warming trends will continue.
Key quote:
"This is more than a statistical oddity and it highlights a large and continuing shift in our climate."
— Carlo Buontempo, director of Copernicus Climate Change Service.
Why this matters:
This sustained warmth has far-reaching consequences. Extreme weather events such as hurricanes, heatwaves and wildfires are becoming more frequent and intense, wreaking havoc on communities and ecosystems. Rising temperatures also accelerate the melting of polar ice, contributing to sea-level rise that threatens coastal cities and island nations.

The complex implications of Earth's increasing greenery
The planet is experiencing a significant increase in green vegetation, but this trend may not be as positive as it seems.
In short:
- Recent studies show a substantial increase in Earth's green vegetation, driven by factors like CO2 fertilization and agricultural expansion.
- While this greening can help absorb more CO2, it often masks the destruction of diverse ecosystems and can lead to negative environmental impacts.
- The trend reflects the extensive human alteration of the planet, raising concerns about biodiversity loss and ecosystem health.
Key quote:
“The intensification of agriculture that’s been happening in India over the past four decades is stunning.”
— Joshua Gray, geospatial scientist at North Carolina State University
Why this matters:
While increased greenery may seem beneficial for climate change mitigation, it often comes at the cost of biodiversity and ecosystem integrity. This underscores the need for a nuanced understanding of environmental changes and their broader implications for the planet's health.
Rising CO2 will leave crops—and millions of humans—less healthy.

Earth is taking a pounding from bigger ocean waves. Why this matters
Stormier seas and larger ocean swell in recent decades are pounding Earth’s seafloor with more force, sending larger ripples through Earth’s crust — almost like a tiny, tiny, tiny earthquake.

The planet’s big blue machine: Why the ocean engine matters
The ocean is an enormous engine, turning heat energy into motion, says physicist Helen Czerski. But human activity is threatening that machine — depriving the seas of oxygen, increasing stratification, and potentially changing the currents that influence global weather.

Are we voting with our wallets to overheat the planet?
Surveys of Canadians have repeatedly shown that a majority would choose to prevent the bad things caused by climate change. Politicians think we won't make sacrifices. Maybe we won't have to.
