'Very hot' 30C days treble in UK, Met Office finds

Thursday 25 July 2024 04:30, UK



The number of 'very hot' days that bake Britons in 30C heat or above has trebled, according to innovative new research.

In spite of this year's disappointing summer of washed out BBQs and cold spells, the UK's climate is still overall getting sunnier, wetter and warmer, the Met Office said today.

In its latest annual review of Britain's favourite topic of conversation, the weather, the Met Office has begun measuring the number of "high impact weather events" that disrupt daily life, such as extremely hot days, or days with exceptional amounts of rain.

It found the number of "hot" days of 28C or more per year has doubled in the decade to 2024 compared with the average from the period 1961-1990, while "very hot" days of at least 30C have trebled.

It comes as "truly staggering" global temperatures smashed records two days in a row this week.

A Window of Opportunity for Climate Change and Biodiversity
July 23, 2024

Introduction:

(Eurekalert) World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists from ZSL and York University. Without this, work on tackling either crisis could inadvertently harm progress on the other.

Published today (Tuesday 23 July) in the Journal of Applied Ecology, a paper from international conservation charity ZSL and researchers at York University, Toronto, titled ‘The Kunming-Montreal Global Biodiversity Framework and the Paris Agreement need a joint work programme for climate, nature, and people’ conceptualises how a joint work programme between the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations Convention on Biological Diversity (CBD) could be established.

Highlighting the issues the joint programme must tackle, and recommendations for successful implementation – the paper argues that such a unified political tool is critical to meet international commitments under both the Paris Agreement and the Kunming-Montreal Global Biodiversity Framework.

Professor Nathalie Pettorelli, who has long been calling for united solutions to tackle climate change and biodiversity loss, is co-author of the paper and researcher at ZSL’s Institute of Zoology explained: “We urgently need a global approach that addresses the nature and climate crises together - because they are intrinsically connected.

Additional Extract:

“Without this, we risk action to tackle one crisis creating major setbacks for the other. For example, the replacement of natural grasslands with forests may help capture and store planet-warming carbon dioxide, but it does so at a cost of the ecosystems and wildlife that previously used the land.”

New 400-year temperature record shows Great Barrier Reef is facing catastrophic damage, researchers warn
https://phys.org/news/2024-08-year-temp ... -reef.html
by University of Wollongong

The Great Barrier Reef is under critical pressure, with warming sea temperatures and mass coral bleaching events threatening to destroy the remarkable ecology, biodiversity, and beauty of the world's largest coral reef, according to new research.

"Highest ocean heat in four centuries places Great Barrier Reef in danger," published in Nature 8 August, led by University of Wollongong (UOW) Honorary Fellow and University of Melbourne Lecturer Dr. Benjamin Henley, provides evidence of the impact that rising sea surface temperatures have had, and will continue to have, on Australia's ecological jewel.

The research reconstructs 400 years of summer sea surface temperatures in the Coral Sea. The results chronicle extreme recent ocean heat that has led to mass coral bleaching on the Great Barrier Reef.

Analysis: China’s CO2 falls 1% in Q2 2024 in first quarterly drop since Covid-19

8 August 2024

[...]

China is likely still on track to begin a structural decline in emissions in 2024, making 2023 the peak year for CO2 emissions.

China has committed to updating its climate targets for 2030 and releasing new targets for 2035 early next year. These targets will be key in cementing the emissions peak and specifying the targeted rate of emission reductions after the peak – both of which have seismic implications for the global emissions trajectory and the level at which temperatures can be stabilised.

Britain's 'smallest house' among heritage sites 'at risk' due to climate change

Friday 9 August 2024 09:13, UK



Britain's "smallest house" is among the sites at risk from climate change, according to a new report.

The tourist attraction, located in Conwy, has suffered from the effects of flooding before.

But Wales's future generations commissioner says it could be at further risk due to the effects of climate change.

It's one of thousands of heritage sites across Wales that are under threat, identified using flood risk mapping.

Jan Tyley, owner and manager of the Smallest House in Great Britain, hopes the report will "raise awareness" and that the council acknowledges the risk posed by flooding.

Fijian coral reveals new 627-year record of Pacific Ocean climate
https://phys.org/news/2024-08-fijian-co ... cific.html
by Monash University

An international team of climate scientists have used a 627-year coral record from Fiji to reveal unprecedented insights into ocean temperatures and climate variability across the Pacific Ocean since 1370.

The study published in Science Advances, co-authored by Dr. Ariaan Purich from Monash University and Professor Matthew England and Dr. Rishav Goyal from UNSW, shows how human-caused climate change is interacting with long-term patterns of climate variability in the Pacific.

The new coral record shows that the local ocean temperature was warm between 1380 and 1553, comparable to the late 20th and early 21st centuries. However, when combined with other coral records, the Pacific-wide warming observed since 1920, largely attributed to human-derived emissions, marks a significant departure from the natural variability recorded in earlier centuries.

When will climate change turn life in the U.S. upside down?

August 19, 2024

[...]

It is inevitable that climate change will stop being a hazy future concern and will someday turn everyday life upside down. Very hard times are coming. At the risk of causing counterproductive climate anxiety and doomism, I offer here some observations and speculations on how the planetary crisis may play out, using my 45 years of experience as a meteorologist, including four years of flying with the Hurricane Hunters and 20 years blogging about extreme weather and climate change.

By late this century, I am optimistic that we will have successfully ridden the rapids of the climate crisis, emerging into a new era of non-polluting energy with a stabilizing climate. There are too many talented and dedicated people who understand the problem and are working hard on solutions for us to fail.

[...]

We may manage to avoid a coastal real estate market crash in the next 10 years if we get lucky with hurricanes and if our politicians continue to pump huge amounts of money to bail out the failing system.

But it will become increasingly difficult to keep the coastal property market propped up beginning in the mid-2030s, because of accelerating sea level rise combined with an 18.6-year wobble in the moon’s orbit. Thus, I expect that the longest we might stave off the popping of the coastal real estate Brittleness Bubble is 15 years.

New Climate Satellite Will Use NASA Instrument to Map Greenhouse Gases
The Tanager-1 satellite is the first launch of the Carbon Mapper Coalition.
By Ryan Whitwam August 20, 2024

In the weeks since SpaceX resumed Falcon 9 launches, the workhorse rocket has lifted off 11 times, all of which have been complete successes. In the most recent Friday (Aug. 16) launch, SpaceX delivered 116 small payloads to orbit, including the Tanager-1 satellite. This is the first orbital asset of the Carbon Mapper Coalition. It carries a new instrument designed by NASA's Jet Propulsion Laboratory (JPL) that will map global greenhouse gas emissions.

While climate change has become a subject of political disagreement, scientists agree that carbon dioxide and methane emissions from human activity are driving higher temperatures and extreme weather. The shiny new Tanager-1 satellite is equipped with an imaging spectrometer designed to detect those gases from orbit. "The imaging spectrometer technology aboard Tanager-1 is the product of four decades of development at NASA JPL and truly in a class of its own," says JPL Director Laurie Leshin.

GOP-led states urge Supreme Court to pause EPA plan meant to cut methane emissions by 80%

By John Fritze, CNN

2 minute read
Published 3:48 PM EDT, Tue August 27, 2024

Republican officials in 24 states asked the Supreme Court on Tuesday to halt a Biden administration effort to reduce emissions of the planet-warming gas methane, adding to a series of emergency appeals challenging environmental regulations.

Led by Oklahoma, the states are asking the high court to pause an Environmental Protection Agency rule that went into effect earlier this year and that the agency estimates will slash methane emissions from oil and gas operations by nearly 80% through 2038.

The latest filing is part of a much broader campaign by the groups battling Biden administration environmental regulations, a push that has repeatedly resonated with the Supreme Court’s conservative majority in recent years.

Many of the same states and industry groups have filed other emergency appeals in recent weeks challenging different regulations, including those to curb power plant pollution and mercury emissions.

UK may unveil tougher emissions targets at Cop29 climate summit

Thu 29 Aug 2024 18.58 BST

The UK government is considering making further commitments on cutting greenhouse gas emissions, likely to be announced at the UN climate summit this year.

It is hoped the plan will help kickstart global ambitions on cutting emissions and encourage other countries to follow suit.

Under the Paris climate agreement countries are obliged to submit more stringent targets on emissions in February, if the world is to have any chance of holding global temperature rises to within 1.5C of preindustrial levels.

But Ed Miliband, the secretary of state for energy security and net zero, hopes to announce a new target months early, and has the support of Keir Starmer, the prime minister, in trying to propel the UK into a leadership position on the international stage at climate negotiations.

Starmer attended the previous summit, Cop28, when he was leader of the opposition and has been invited to Cop29, which will take place in Azerbaijan in November.

Italy’s Marmolada glacier could disappear by 2040, experts say

Tue 10 Sep 2024 17.22 BST

The Marmolada glacier, the largest and most symbolic of the Dolomites, could melt completely by 2040 owing to rising average temperatures, experts have said.

Italian scientists who are monitoring glaciers and the impact of climate emergency, and who took part in a campaign launched by environmentalist group Legambiente, the international commission for the protection of the Alps (Cipra), with the scientific partnership of the Italian Glacier Committee, said on Monday the Marmolada was losing between 7 and 10cm of depth a day.

Over the past five years 70 hectares (173 acres) of its surface – equalling 98 football fields – have disappeared.

Since the beginning of scientific measurements in 1888, the Marmolada glacier has withdrawn by 1,200 metres in an “irreversible coma”, according to organisers of the campaign, titled Caravan of Glaciers.

The effects of climate emergency are visible all across the Dolomites, which have experienced winter droughts with very little snowfall. According to experts, this, combined with the unusually high temperatures across the region over the summer, is causing glaciers to rapidly melt.

August 2024

The average global land and ocean surface temperature in August was 2.29 degrees F (1.27 degrees C) above the 20th-century average of 60.1 degrees F (15.6 degrees C), ranking as the warmest August in the global climate record. This August marks the 15th-consecutive month of record-high global temperatures — which is itself a record streak.

Europe and Oceania had their warmest August on record, Asia saw its second-warmest while Africa and North America each had their third-warmest August.

Year-to-date Temperature: January–August 2024

The January–August global surface temperature was the warmest in the 175-year record at 1.28°C (2.30°F) above the 1901-2000 average of 14.0°C (57.2°F).
