Confirmed: 2023 the hottest year on record
The Copernicus Climate Change Service (C3S) has confirmed that 2023 is the hottest year on record with the latest climate data from November. The organisation says the world has seen six record-breaking months this year, and two record-breaking seasons. “The extraordinary global November temperatures, including two days warmer than 2°C above pre-industrial [reference period], mean […]

Southern hemisphere clocks warmest month on record
April 2023 was the southern hemisphere’s hottest month on record, beating the previous record set in March 2016 by 0.06°C. The record passed almost without comment or substantial media coverage, such is the level of desensitisation of a rapidly heating planet. April also happened to be the fourth hottest April globally since modern recordkeeping began […]

Propane AC could help avoid global temperature rises
A report published at the Proceedings of the National Academy of Sciences (PNAS) has highlighted the emissions that could be avoided by switching to propane as a refrigerant in split-system air conditioners. The research team estimates that such a transition could avoid a 0.09°C increase in global temperature by the end of the century. Global […]

Now or never for emissions reduction, says IPCC
The latest report from the Intergovernmental Panel on Climate Change (IPCC) says that immediate and deep emissions reductions are required across all sectors to limit global warming to the levels set out in the Paris Agreement. The report, Climate Change 2022: Mitigation of Climate Change, provides an updated global snapshot of actions and pledges to […]

Building for a future climate
Global warming is pushing temperatures upwards, but are Australia’s buildings being designed to handle these future conditions? Probably not, according to a report produced by DeltaQ for the COAG Energy Council. The report aims to quantify the impacts of climate change on the built environment, and recommend how building regulations should adapt. “The key thing […]

HVAC&R is the key to averting climate crisis
A new report from the United Nations Environment Programme (UNEP) and the International Energy Agency (IEA) has flagged the huge potential of the HVAC&R sector to reduce global emissions. The Cooling Emissions and Policy Synthesis Report notes that over the next four decades, international action on energy-efficient, climate-friendly cooling could avoid as much as 460 […]

Prize finalists to be announced
The Global Cooling Prize has announced that its finalist award ceremony will take place on November 15, 2019, in New Delhi, India. The prize seeks to catalyse innovation by calling upon global innovators to develop cooling solutions that have at least five times less climate impact than standard entry-level room air conditioning technology in operation […]

June 2019 the hottest on record
Buoyed by historic heatwaves in Europe and warmer conditions in the Arctic and Eurasia, June 2019 was the hottest on record. According to data released by NASA and the Copernicus Climate Change Service (C3S), Earth soared to its highest level recorded in June. Records stretch back almost 140 years. “The record warm streaks we’ve seen in […]

Extreme weather triggers AC overload
Temperatures of over 43°C in Southern California and the associated increase in air conditioning demand has led to a series of blackouts across Los Angeles. And it may be a sign of things to come. Almost 100,000 customers in LA were left without power during a heatwave that set new records. According to the Los […]
