Global warming: Phoenix in US on the cusp of a new heat record
World
UN says more needed 'on all fronts' to meet climate goals
PHOENIX/NEW YORK (AP/Reuters) — Phoenix is on the cusp of yet another heat-related record this summer after an additional day of 110-degree weather, as the United Nations warned on Friday that the world is not on target to curb global warming with more action required on all fronts.
The National Weather Service said the desert city on Friday saw 110 degrees Fahrenheit (43.3 Celsius) for the 53rd day this year, tying it with the record set in 2020. If Phoenix reaches 110 degrees or more as expected Saturday, it would mark a record 54 days in one year.
An extreme heat warning is in effect for the entire weekend, with temperatures forecast as high as 113 degrees Fahrenheit (45 Celsius) on Saturday and 111 degrees Fahrenheit (43.8 Celsius) on Sunday. A high of 109 degrees Fahrenheit (42.7 Celsius) is forecast for Monday.
In July, Phoenix set a record with a 31-day streak of highs at or above 110 degrees. The previous record was 18 straight days, set in 1974.
It was part of a historic heat wave that stretched from Texas across New Mexico and Arizona and into California’s desert.
Phoenix has now seen over 100 days with 100-degree Fahrenheit-plus (37.7 C-plus) temperatures this year as of Wednesday. That’s in line with the average of 111 days hitting triple digits every year between 1991 and 2020.
Maricopa County, home to Phoenix and the most populous county in Arizona, also appears headed toward an annual record for heat-associated deaths.
County public health officials said Wednesday that there have been 194 heat-associated deaths confirmed for this year as of Sept 2. An additional 351 are under investigation.
Maricopa County confirmed 425 heat-related deaths in 2022.
MORE NEEDED ON ALL FRONTS
The Global Stocktake report, the latest warning from the UN about environmental perils, will form the basis of the COP28 talks in Dubai at the end of the year and follows months of wildfires and soaring temperatures.
The report, culminating a two-year evaluation of the 2015 Paris climate agreement goals, distils thousands of submissions from experts, governments and campaigners and will lay the groundwork for the global stock-take discussion at COP28.
"The Paris Agreement has driven near-universal climate action by setting goals and sending signals to the world regarding the urgency of responding to the climate crisis," it said. "While action is proceeding, much more is needed now on all fronts."
Nearly 200 countries agreed in 2015 in Paris to limit warming to no more than 2 Celsius above pre-industrial levels, and to strive to keep the increase to 1.5 C.
While each country is responsible for deciding its own climate actions, they also agreed to submit to a progress report by 2023 to see what more should be done.
The UN said existing national pledges to cut emissions were insufficient to keep temperatures within the 1.5 C threshold.
More than 20 gigatonnes of further CO2 reductions were needed this decade - and global net zero by 2050 - in order to meet the goals, the UN assessment said.
On Friday, some of the world's most climate vulnerable countries said the report should spur action from global leaders.
"With leaders gathering this month for the United Nations Secretary General’s Climate Ambition Summit ahead of COP28, the findings and recommendations of this Report need to be a wake-up call and a trigger for cogent commitments," said Pa'olelei Luteru, chair of the Association of Small Island States.
'BOLD TO-DO LIST'
The report urged countries to cut the use of "unabated" coal power by 67-92 per cent by 2030 versus 2019 levels and to virtually eliminate it as a source of electricity by 2050.
Low and zero-carbon electricity should account for as much as 99pc of the global total by mid-century, while technological challenges holding back carbon capture must be resolved.
The report also called for funding to be unlocked to support low-carbon development, noting that billions of dollars were still being invested in fossil fuels.
"It serves up a bold to-do list for governments to limit warming to 1.5C and protect people everywhere from climate devastation," said Tom Evans, policy advisor on climate diplomacy at British climate think tank E3G.
Commitment is needed to phase out fossil fuels, set 2030 targets for renewable energy expansion, ensure the financial system funds climate action, and raise funds for adaptation and damage, he said.
"Anything less will fall short on the necessary steps laid out in this report."
Sultan Al Jaber, who will preside over the Nov 30-Dec 12 summit in the United Arab Emirates (UAE), told Reuters the stock take gave good direction, and urged states and private sector leaders to come to COP28 with real commitments.
Also on Friday, UN Secretary-General Antonio Guterres told G20 bloc leaders that they have the power to reset a climate crisis that is "spinning out of control".
A Brazilian climate official told Reuters: "What we need is an unprecedented mobilization both in terms of scale and speed of all of humanity’s financial, technology, and capacity building resources to be channelled towards sustainable development."
