United in Science: We are heading in the wrong direction

United in Science: We are heading in the wrong direction Link contains a summary of the report’s findings

Geneva, 13 September 2022 (WMO) – Climate science is clear: we are heading in the wrong direction, according to a new multi-agency report coordinated by the World Meteorological Organization (WMO), which highlights the huge gap between aspirations and reality. Without much more ambitious action, the physical and socioeconomic impacts of climate change will be increasingly devastating, it warns.

The report, United in Science, shows that greenhouse gas concentrations continue to rise to record highs. Fossil fuel emission rates are now above pre-pandemic levels after a temporary drop due to lockdowns. The ambition of emissions reduction pledges for 2030 needs to be seven times higher to be in line with the 1.5 °C goal of the Paris Agreement

The past seven years were the warmest on record. There is a 48% chance that, during at least one year in the next 5 years, the annual mean temperature will temporarily be 1.5°C higher than 1850-1900 average. As global warming increases, “tipping points” in the climate system can not be ruled out.

Met Office: Climate change making heatwaves more intense

https://www.metoffice.gov.uk/about-us/press-office/news/weather-and-climate/2022/southern-asian-heatwave-attribution-study-2022

A Met Office attribution study, produced this week, has estimated the chances of exceeding the record-breaking temperature witnessed in April and May in 2010 – which saw the highest combined average April and May temperature since 1900.

The study shows that the natural probability of a heatwave exceeding the average temperature in 2010 is once in 312 years. In the current climate – accounting for climate change – the probabilities increase to once in every 3.1 years. And by the end of the century, the study – incorporating climate change projections – shows this will increase to once every 1.15 years.

Dr Nikos Christidis produced the Met Office attribution study. He said: “Spells of heat have always been a feature of the region’s pre-monsoon climate during April and May. However, our study shows that climate change is driving the heat intensity of these spells making record-breaking temperatures 100 times more likely. By the end of the century increasing climate change is likely to drive temperatures of these values on average every year.”

Climate change swells odds of record India, Pakistan heatwaves

Climate change makes record-breaking heatwaves in northwest India and Pakistan 100 times more likely, a Met Office study finds.

The region should now expect a heatwave that exceeds the record temperatures seen in 2010 once every three years.

Without climate change, such extreme temperatures would occur only once every 312 years, the Met Office says.

The UN Secretary General, Antonio Guterres described the report as “a dismal litany of humanity’s failure to tackle climate disruption.”

Climate change: UN emissions gap report a ‘thundering wake-up call’

https://www.bbc.com/news/science-environment-59049770

National plans to cut carbon fall far short of what’s needed to avert dangerous climate change, according to the UN Environment Programme.

Their Emissions Gap report says country pledges will fail to keep the global temperature under 1.5C this century.

The Unep analysis suggests the world is on course to warm around 2.7C with hugely destructive impacts.

Just a few days before COP26 opens in Glasgow and another scientific report on climate change is “another thundering wake-up call”, according to the UN Secretary General, Antonio Guterres.
