Human activities like burning fossil fuels and farming livestock are the main drivers of climate change, according to the UN's intergovernmental panel on climate change. This causes heat-trapping greenhouse gas levels in Earth's atmosphere, increasing the planet's surface temperature.

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.

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.'

And it continues to rise. As of June 5, carbon dioxide in the atmosphere has risen to 430.51 parts per million, up from 429.64 ppm last month and 427.09 ppm in March, according to NOAA data 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.

• The Earth is now about 1.3 C warmer than it was in the 1800s.
• 2024 was hottest year on record globally, beating the record in 2023.
• 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.
• The past 10 years (2015-2024) are the 10 warmest on record.
• 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.
• On the current path of carbon dioxide emissions, the temperature could increase by as much 3.6 C this century, according to the IPCC.
• In June 2025, global concentrations of carbon dioxide exceeded 430 parts per million, a record high.
• Emissions must drop 7.6 per cent per year from 2020 to 2030 to keep temperatures from exceeding 1.5 C and 2.7 per cent per year to stay below 2 C.
• There is global scientific consensus that the climate is warming and that humans are the cause.

Private spaceflight ends with a Pacific splashdown for astronauts from India, Poland and Hungary
CAPE CANAVERAL, Fla. (AP) — A private spaceflight featuring the first astronauts in more than 40 years from India, Poland and Hungary came to a close Tuesday with a Pacific splashdown. Their SpaceX capsule undocked from the I nternational Space Station on Monday and parachuted into the ocean off the Southern California coast, less than 24 hours later. The crew of four launched nearly three weeks ago on a flight chartered by the Houston company Axiom Space. Axiom's Peggy Whitson, the most experienced U.S. astronaut, served as commander. Joining her were India's Shubhanshu Shukla, Poland's Slawosz Uznanski-Wisniewski and Hungary's Tibor Kapu, whose countries paid more than $65 million apiece for the mission. The visiting astronauts conducted dozens of experiments in orbit while celebrating their heritage. The last time India, Poland and Hungary put anyone in space was during the late 1970s and 1980s, launching with the Soviets. It was Axiom's fourth mission to the orbiting outpost since 2022, part of NASA's ongoing effort to open up space to more businesses and people. The company is one of several developing their own space stations to replace the current one. NASA plans to abandon the outpost in 2030, after more than 30 years of operation. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.

US won't publish major climate change report, despite promise
The Trump administration on Monday took another step to make it harder to find major, legally mandated scientific assessments of how climate change is endangering the nation and its people. Earlier this month, the official government websites that hosted the authoritative, peer-reviewed national climate assessments went dark. Such sites tell state and local governments and the public what to expect in their backyards from a warming world and how best to adapt to it. At the time, the White House said NASA would house the reports to comply with a 1990 law that requires the reports, which the space agency said it planned to do. But on Monday, NASA announced that it aborted those plans. 'The USGCRP (the government agency that oversees and used to host the report) met its statutory requirements by presenting its reports to Congress. NASA has no legal obligations to host data," NASA Press Secretary Bethany Stevens said in an email. That means no data from the assessment or the government science office that coordinated the work will be on NASA, she said. On July 3, NASA put out a statement that said: "All preexisting reports will be hosted on the NASA website, ensuring continuity of reporting.' 'This document was written for the American people, paid for by the taxpayers, and it contains vital information we need to keep ourselves safe in a changing climate, as the disasters that continue to mount demonstrate so tragically and clearly,' said Texas Tech climate scientist Katharine Hayhoe. She is chief scientist at The Nature Conservancy and co-author of several past national climate assessments. Copies of past reports are still squirreled away in the National Oceanic and Atmospheric Administration's library and the latest report and its interactive atlas can be seen here. Former Obama White House science adviser and climate scientist John Holdren accused the administration of outright lying and long intended to censor or bury the reports. 'The new stance is classic Trump administration misdirection,' Holdren said. 'In this instance, the administration offers a modest consolation to quell initial outrage over the closure of the site and the disappearance of the National Climate Assessments. Then, two weeks later, they snatch away the consolation with no apology.' 'They simply don't want the public to see the meticulously assembled and scientifically validated information about what climate change is already doing to our farms, forests, and fisheries, as well as to storms, floods, wildfires, and coast property — and about how all those damages will grow in the absence of concerted remedial action,' Holdren said in an email. That's why it's important that state and local governments and every day people see these reports, Holdren said. He said they are written in a way that is 'useful to people who need to understand what climate change is doing and will do to THEM, their loved ones, their property and their environment." 'Trump doesn't want people to know,' Holdren wrote. The most recent report, issued in 2023, found that climate change is affecting people's security, health and livelihoods in every corner of the country in different ways, with minority communities, particularly Native Americans, often disproportionately at risk. ___

Trump administration says it won't publish major climate change report on NASA website as promised
