The panel, which is made up of scientists from around the world, including researchers from B.C., has warned for decades that wildfires and severe weather, such as the province’s deadly heat dome and catastrophic flooding in 2021, would become more frequent and intense because of the climate emergency. It has issued a code red for humanity and warns the window to limit warming to 1.5 C above pre-industrial times is closing.
Article content
According to NASA climate scientists, human activities have raised the atmosphere’s carbon dioxide content by 50 per cent in less than 200 years, and “there is unequivocal evidence that Earth is warming at an unprecedented rate.”
Article content
As of June 5, 2026, carbon dioxide in the atmosphere was 432.34 parts per million, up slightly from 431.12 ppm the previous month, according to the latest available data from the NOAA measured at the Mauna Loa Observatory, a global atmosphere monitoring lab in Hawaii. The NOAA notes there has been a steady rise in CO2 from under 320 ppm in 1960.

Quick facts:
Article content
• The global average temperature in 2023 reached 1.48 C higher than the pre-industrial average, according to the EU’s Copernicus Climate Change Service. In 2024, it breached the 1.5 C threshold at 1.55 C.
• 2025 was the third warmest on record after 2024 and 2023, capping the 11th consecutive warmest years.
• Human activities have raised atmospheric concentrations of CO2 by nearly 49 per cent above pre-industrial levels starting in 1850.
• The world is not on track to meet the Paris Agreement target to keep global temperature from exceeding 1.5 C above pre-industrial levels, the upper limit to avoid the worst fallout from climate change including sea level rise, and more intense drought, heat waves and wildfires.
• UNEP’s 2025 Emissions Gap Report, released in early December, shows that even if countries meet emissions targets, global temperatures could still rise by 2.3 C to 2.5 C this century.
• In June 2025, global concentrations of carbon dioxide exceeded 430 parts per million, a record high.
• There is global scientific consensus that the climate is warming and that humans are the cause.

B.C. First Nations want details, consultations on $44-billion proposed oil pipeline to Roberts Bank
Article content
A day after Alberta and Canada announced a southern route ending in Roberts Bank in Delta for a proposed new oil pipeline, First Nations say they will need to see more project details and be adequately consulted before taking a position.
Article content
“The main message is that we need meaningful engagement, and consultation in alignment with our constitutionally protected treaty rights,” Tsawwassen First Nation executive councillor Valerie Cross told Postmedia.
Article content
The estimated $35 billion to $44 billion proposed project includes a pipeline that would largely follow the existing Trans Mountain oil pipeline from Alberta south through B.C., with a 2.6 square kilometre terminal that will include storage tanks and two berths that can accommodate supertankers.

Western Europe braces for repeated heat waves through July
Article content
As Europe’s record-breaking heat wave recedes, the elements for the next hot spell are coalescing over the Atlantic Ocean.
Article content
Over the next few days, a region of high pressure is forecast to approach the continent and spread, pushing out cooler weather and resurrecting unusually hot conditions across Spain, France and the U.K. Highs over Portugal and southern Spain are expected to reach 43 C and 41 C, respectively, this week, while Paris hit 30 C by Friday and London will hit 31 C on Monday.

Climate change is increasing the frequency and intensity of heat waves on the world’s fastest-warming continent, straining health, transport and power systems, while exposing the housing vulnerabilities of cities like London. Still, the third heat wave to hit western Europe since the last week of May is unlikely to bring the extreme temperatures that seared the region last month, according to U.K. Met Office meteorologist Alex Burkill.
Article content
“At this stage it doesn’t look like it will be as exceptionally hot or as humid as it was for many of us last week,” Burkill said in a video briefing. The high pressure is set to raise average temperatures from 3 C to 7 C across the region next week.

Scientists said climate change increases the frequency of extreme heat, and makes heat waves hotter, longer, and more widespread.
Article content
The latest climate projections show that by the second half of this century, many Canadian cities will see two to four times as many days over 30 C days per year and is increasingly stalling weather patterns and making long-lasting heat domes nearly three times more common today than in the 1950s.
Article content
In 2025, Canada experienced 12 extreme heat events, each made two to 10 times more likely due to climate change, the scientists said.
