    NSW, Queensland and Tasmania experienced hottest winters with spring likely to deliver hotter than average temperatures too

    Australia’s winter of 2023 was the warmest since official records began in 1910, with average daily temperatures 1.53C above the long-term average.

    According to data from the Bureau of Meteorology released on Friday, the 2023 winter beat the previous record of 1.46C above the average set in 1996. Every winter since 2012 has been warmer than the 30-year average calculated from 1961 to 1990.

    Global heating and weather conditions that delivered sunny days were behind the record, scientists said.

    …

    Dr Andrew King, a climate scientist at the University of Melbourne, said the winter warmth was “pretty consistent with the trend towards warming that we have already seen and expect to continue as we keep emitting greenhouse gases”.

    King said the high-pressure systems that brought the extra warmth were “part of the story”, adding “we would not get the temperatures that we have seen this winter really happening without human-caused climate change”.

  • Could Climate Change cause an Ocean Tipping Point… Soon..?

    The huge ocean current known as the Atlantic Meridional Overturning Circulation (AMOC – not the Gulf Stream!) shifts vast amount of water around the world. But scientists fear that by heating the planet and melting the Greenland ice-sheet, we’re already slowing it down, with the risk that it could collapse – a potential tipping point with huge consequences around the world. And a new study (published in 2023) has tried to pin down what could happen, when. So what do we actually known about this current, does it have anything to do with the Gulf Stream, and is there anything we can do to protect ourselves?

  • Exxon Still Has Its Foot on the Accelerator of the Climate Emergency

    If one oil company is synonymous with funding decades of climate denial, it is Exxon. For decades, the oil giant copied the deadly playbook of Big Tobacco of sowing doubt about the evidence and delaying action.

    The company funded a covert network of foot soldiers to deny evidence, delay action, and divert away from the industry. Between the late ’90s and 2005, the oil giant donated $16 million to numerous right-wing and libertarian think tanks to manufacture uncertainty about climate change.

    The oil company spread such confusion and obfuscation despite knowing for decades that fossil fuels would cause global warming. The company knew by the ’60s that climate change could have catastrophic consequences. For example, a report for the American Petroleum Institute, on which Exxon is a prominent member, warned of the dangers of climate change and the risks to sea level rise if Antarctic glaciers melted.

    We must keep trying to hold the companies to account for their failure to act, for their failure to future generations.

    Nine years later, in 1977, Exxon’s leaders were told directly by a senior company scientist, James F. Black, about the looming climate crisis. “In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” he told Exxon’s Management Committee.

    Decades after the company was first warned about climate change, in October 1997, the head of Exxon at the time, Lee “iron ass” Raymond, delivered a speech to the Fifteenth World Petroleum Congress in China.

    As Steve Coll recalls in his book Private Empire, Raymond “devoted 33 paragraphs of his 78-paragraph speech to the argument that evidence about manmade climate change was an illusion.”

    Months later, Exxon helped create a task force working with the American Petroleum Institute: “Victory will be achieved when average citizens understand (recognize) uncertainties in climate science” and when public “recognition of uncertainty becomes part of ‘unconventional wisdom.’” Where Big Tobacco led, Exxon followed with devastating consequences.

    In 2006, nearly three decades after Exxon was first warned about climate change, the British Royal Society wrote to Exxon asking the company to stop funding organizations that feature information “on their websites that misrepresented the science of climate change, by outright denial of the evidence that greenhouse gases are driving climate change, or by overstating the amount and significance of uncertainty in knowledge or by conveying a misleading impression of the potential impacts of anthropogenic climate change.”

    When Raymond retired, the Independent newspaper ran a front-page headline the following year: “The man who sold the planet.” The paper called Exxon the “Darth Vader of global warming” for its “denial that carbon emissions cause climate change.”

  • Greenpeace says new Energy Secretary Claire Coutinho has a lot of catching up to do

    Commenting on the appointment of Claire Coutinho as the new Energy and Net Zero Secretary, Greenpeace UK’s policy director Dr Doug Parr said:

    “We don’t envy the new energy secretary’s job. She’s picked up the baton for the final leg of a relay where her fellow runners have mostly been walking, sometimes backwards. Her department has a huge amount of catching up to do to tackle both the energy and climate challenges in her new job title.

    “Fortunately, there are plenty of things that will deliver on both, from removing absurd blockages to cheap renewables to fixing our energy-wasting homes and bringing our power grid into the 21st century.

    “In her maiden speech, Claire Coutinho described renewables as ‘one of the most remarkable success stories in the UK today’. Perhaps she could persuade the Prime Minister to build on that success story instead of blocking it. If she can do that, it’ll be good news for bill payers, the climate and the economy. We wish her best of luck with that.”

  • Hurricane Idalia could become 2023’s costliest climate disaster for the US

    Analysts estimate the category 3 storm has already racked up a preliminary cost of $9.36bn, straining the insurance industry

    Hurricane Idalia could become the costliest climate disaster to hit the US this year, analysts say, with massive implications for insurance and risk management industries.

    The category 3 storm that barreled into Florida’s west coast from the Gulf of Mexico on Wednesday, then carved a path of destruction and flooding through Georgia and the Carolinas, has a preliminary price tag of $9.36bn, based on early estimates, according to risk analysts at UBS.

    It follows 15 previous “individual weather and climate disasters” recorded in the US already this year by the National Oceanic and Atmospheric Administration (Noaa) as unprecedented heat, wildfires, storms and floods escalate.

    Cumulatively, Noaa said that by the end of July, which Nasa said was Earth’s hottest month on record, the total estimated cost of the damage caused by the disasters was $39.7bn. That figure does not include the estimated $5.5bn cost to rebuild the town of Lahaina following devastating wildfires that razed the Hawaii island of Maui this month.
