Great Barrier Reef suffers sixth mass bleaching event
with 91% of reefs surveyed affected

By Hilary Whiteman, Hannah Ritchie and Helen Regan, CNN

Updated 0445 GMT (1245 HKT) May 11, 2022

(CNN)Warming waters from escalating climate change have caused coral bleaching in 91% of reefs surveyed along the Great Barrier Reef this year, according to new findings from an Australian government agency.
Scientists from the Great Barrier Reef Marine Park Authority (GBRMPA) confirmed in March this was the sixth mass bleaching event of the reef on record and the fourth since 2016.
But Tuesday's report, Reef snapshot: summer 2021-22, found almost every coral reef surveyed across the 1,400 mile (2,300 kilometer) system was impacted by bleaching.

Coral reefs are some of the most vibrant marine ecosystems on earth -- between a quarter and one third of all marine species rely on them at some point in their life cycle. But the rapid warming of the planet due to human emissions of heat-trapping gases is causing above average water temperatures, leading to stress events like mass bleaching.

Coral bleaching tends to happen when water temperatures are much warmer than normal. But for the first time, this mass bleaching comes despite La Niña, a weather event which is characterized by cooler-than-normal temperatures across the equatorial Pacific Ocean, the Authority's scientists said.

Scientists say time is running out for the reefs to be able to recover and that governments urgently need to address the root cause: the climate crisis.

"To give our reef a fighting chance, we must deal with the number one problem: climate change. No amount of funding will stop these bleaching events unless we drive down our emissions this decade," said Amanda McKenzie, CEO of the Climate Council in March.

Another sky mapping of the reef. Hoping to see colour in reefs from 100feet.

"Map 1: 2022 Aerial Survey observations of reef community coral bleaching throughout the Great Barrier Reef after the final heat wave from 12-23 March 2022. A total of 719 reefs were surveyed by a combination of helicopter and fixed-wing aircraft."

"Of these, 654 reefs (91 per cent) exhibited some bleaching."

https://www.gbrmpa.gov.au/the-reef/reef-health

So some bleaching - 1%? 99%?

Another view -

"But much like carbon. Depending on how it’s made, distributed and used, it could even make warming worse over the next few decades, even if carbon poses the bigger long-term threat. Any future hydrogen-based economy, they say, must be designed from the start to keep leaks of the gas to a minimum, or it risks adding to the very problem it’s supposed to solve. Some ideas now being tested, like shipping hydrogen in pipelines built to hold natural gas or burning it in individual homes, could cause an unacceptable level of leaks.

“The potency is a lot stronger than people realize,” said Ilissa Ocko, a climate scientist with the Environmental Defense Fund, a non-profit group. “We’re putting this on everyone’s radar now not to say ‘no’ to hydrogen but to think about how we deploy it.”

Hydrogen doesn’t trap heat directly, the way CO₂ does. Instead, when leaked it sets off a series of chemical reactions that warm the air, acting as an indirect greenhouse gas. And though it cycles out of the atmosphere far faster than carbon dioxide, which lingers for centuries, it can do more damage than CO₂ in the short term. Over 20 years, it has 33 times the global warming potential of an equal amount of carbon dioxide, according to a recent UK government report. Over hundreds of years, carbon is more dangerous, due to its longevity.

Hydrogen’s warming potential was never a problem before, as its use was largely limited to oil refineries and chemical or fertilizer plants. But now governments worldwide are investing billions to build a hydrogen economy, seeing the gas as one of the only options for decarbonizing many industries that can’t easily run on electricity. President Joe Biden has set aside $8 billion to build at least four “hydrogen hubs” where the fuel will be produced and used, and states are gearing up to compete. US utility companies that now deliver natural gas see it as a savior, announcing more than two dozen hydrogen pilot projects in the last two years."

Shocking heat wave in Spain and France - also India and USA.

Europe heatwave: Outdoor events banned in parts of France

Published

15 hours ago

Outdoor public events have been banned in an area of France as a record breaking heatwave sweeps across Europe.

Concerts and large public gatherings have been called off in the Gironde department around Bordeaux.

On Thursday, parts of France hit 40C earlier in the year than ever before, with temperatures expected to peak on Saturday.

Scientists say periods of intense heat are becoming more frequent and longer lasting as a result of global warming.

Spain, Italy and the UK are also experiencing high temperatures.

What is climate change?
Live updates on heatwave

In Gironde, officials said public events, including some of the official 18 June Resistance celebrations, will be prohibited from Friday at 14:00 (12:00 GMT) "until the end of the heat wave". Indoor events at venues without air-conditioning are also banned.

Private celebrations, such as weddings, will still be allowed.

"Everyone now faces a health risk", local official Fabienne Buccio told France Bleu radio.

The French interior ministry warned people to be extremely careful and not expose themselves to the weather.

State forecaster Meteo France said it was the earliest hot spell ever to hit the country, which has been caused by a mass of hot air moving from north Africa.

Extreme heat isn't confined to Europe this week.

On Wednesday a third of the entire population of the United States were advised to stay indoors due to record temperatures. In India, Delhi has recorded a maximum temperature of at least 42C on 25 days this summer, the India Meteorological Department reported.

Climate change is causing global temperatures to rise. Greenhouse gases, like carbon dioxide, released into Earth's atmosphere in large volumes are trapping the sun's heat, causing the planet to warm.

This has brought more extreme weather, including record-breaking high temperatures across the world.

As opposed to the heatwave in May? Grin

"According to François Jobard, forecaster for Météo France, “since at least 1947, there has never been a ‘heat wave’ in May, because the hottest day in May remained well below 25.3 ° C (22.9°C: May 28, 2017). In fact, until now, this threshold has never been reached before a June 20""

They seem to have forgotten 35C days in May.

Edit: They have even had 32C days in April.

In pictures: Europe swelters in blistering June heat

Published

15 hours ago

Parts of western Europe are experiencing more extreme heat this weekend under a wave of hot air that has moved north from Africa.

Temperatures in both Spain and France have broken records, putting pressure on hospitals and energy grids.

French officials forecast some areas will reach 42C (107.6F) on Saturday.

Scientists warn that climate change is making periods of intense heat
strike more frequently and earlier in the year, and be more severe.

France is experiencing the country's earliest recorded heatwave since records began in 1947, its meteorological agency said.

Farmers in Italy warned of the impact of drought on their harvests, with water levels in the River Po down by nearly three-quarters compared with seasonal averages. In Spain, firefighters tackled forest blazes in Catalonia.

Four ways to understand why Australia is so cold
right now despite global warming

by Michael Grose, The Conversation

1. Put the weather in a long-term context

The recent cold conditions in some parts of Australia haven't been seen in decades, but they aren't unprecedented.
In Melbourne, for instance, the first two weeks of June were coldest since 1949.
In Brisbane, they were the coldest since 1990.

Under the global warming trend, cold events such as these are becoming less and less likely. But Australia naturally has a variable climate, which means they, of course, still do occur.

And given Australia's instrumental records go back only 112 years (a relatively short length of time), it's actually still possible we'll see new record cold temperatures, even in a warming climate.

Still, record hot temperatures in Australia are being broken 12 times more often than cold ones.

The climate would need to be warming incredibly fast for there to be zero cold records broken, and even faster still if we were to see no cold weather at all. No one suggests this is the reality.

plenty more to read on the link above.

Japan swelters in worst heatwave since 1875

Published 5 hours ago.

Japan is sweltering under the hottest day yet of its worst heatwave for almost 150 years.

The blistering heat has drawn official warnings of a looming power shortage, and led to calls for people to conserve energy where possible.

But the government is still advising people to use use air conditioning to avoid heatstroke as cases of hospitalisation rise with the heat.

Weather officials warn the heat is likely to continue in the coming days.

Heatwaves have become more frequent, more intense, and last longer because of human-induced climate change.

The world has already warmed by about 1.1C since the industrial era began and temperatures will keep rising unless governments around the world make steep cuts to emissions.

Tokyo charted temperatures above 35 degrees on Wednesday for a fifth straight day, marking the worst documented streak of hot weather in June since records started in 1875.

Meanwhile, the city of Isesaki, northwest of the capital, saw a record 40.2C - the highest temperature ever recorded in June for Japan.

Four ways to understand why Australia is so cold
right now despite global warming

by Michael Grose, The Conversation

Given the amount of rain around at this time of year, it is difficult to say that Australia is very cold. The humidity in the air will keep the minimum temperatures warmer than usual. I drove around tonight with the air conditioning on. I did not feel cold at all. Even southern Australia seems to only have the cold in the usual areas. A few years ago, people in Melbourne were going on about frozen water pipes, etc. Not this year.
