Environment and Climate Change Canada is forecasting a hotter-than-normal summer for British Columbia, as the province grapples with a series of climate-related events. Here is the latest local and international news concerning climate change and biodiversity loss for the week of June 1 to June 7, 2026.
Key Developments This Week
Metro Vancouver will implement stage 3 water restrictions starting Monday, June 8, due to low reservoir levels and prolonged dry conditions. Residents are prohibited from watering lawns, filling pools, and washing cars. Meanwhile, an out-of-control wildfire in B.C.'s Cariboo region has prompted an evacuation alert for nearby communities. The BC Wildfire Service reports the fire has grown rapidly, fueled by hot and dry weather.
In other news, B.C. Hydro has cancelled plans to phase out gas-powered generation, citing an impending electricity gap as demand outpaces supply from renewable sources. This decision has sparked debate among environmental groups and policymakers.
Global Climate Context
Human activities, particularly the burning of fossil fuels and livestock farming, remain the primary drivers of climate change, according to the UN's Intergovernmental Panel on Climate Change (IPCC). These activities increase heat-trapping greenhouse gas levels in the atmosphere, raising global surface and ocean temperatures.
The IPCC, comprising scientists from around the world including B.C. researchers, has long warned that extreme weather events—such as the deadly heat dome and catastrophic flooding in 2021—would become more frequent and intense due to the climate emergency. The panel has issued a 'code red for humanity,' emphasizing that the window to limit warming to 1.5°C above pre-industrial levels is closing rapidly.
NASA climate scientists confirm that human activities have raised atmospheric carbon dioxide (CO2) concentrations by 50% in less than 200 years. As of May 5, 2026, CO2 levels reached 431.12 parts per million (ppm), up from 429.35 ppm the previous month, according to NOAA data from the Mauna Loa Observatory in Hawaii. This marks a steady increase from under 320 ppm in 1960.
Quick Facts on Climate Change
- The global average temperature in 2023 was 1.48°C higher than the pre-industrial average; in 2024, it breached the 1.5°C threshold at 1.55°C.
- 2025 was the third warmest year on record, capping the 11th consecutive warmest years.
- Human activities have raised atmospheric CO2 by nearly 49% above pre-industrial levels (since 1850).
- The world is not on track to meet the Paris Agreement target of limiting warming to 1.5°C, with current trajectories risking 2.3°C to 2.5°C rise by century's end.
- In June 2025, global CO2 concentrations exceeded 430 ppm, a record high.
- There is overwhelming scientific consensus that the climate is warming and that human activity is the primary cause.
