Singapore Airlines: Passengers recall horror onboard flight
One passenger said he heard a woman "screaming in agony" and saw another with a "gash on her head".
www.google.com
You remember the Singapore-bound Boeing 777-300ER diverted to Bangkok following the mid-air incident because of a clean air turbulance, making an emergency landing at 15:45 local time (08:45 GMT) with some 211 passengers and 18 crew aboard and which got 104 people treated in hospital, 58 people remain in hospital, 20 of whom are in the intensive care unit, and 73-year-old British man, Geoff Kitchen, died from a suspected heart attack onboard?
Well clean air turbulances hitting planes are getting worse because of the Climate Change issue.
Aircraft turbulence is worsening with climate change. Studying birds could help
Our skies are getting bumpier, making the need to understand and predict turbulence increasingly urgent. Researchers propose birds could provide clues.

BREAKING NEWS!
OMG again! A SECOND plane is hit by dangerous turbulence in just a few days.
Emergency Services at Dublin Airport after passengers and crew injured by turbulence on Quatar Airways flight. 12 people were injured on the flight because of the turbulence.
This is what happens WHEN THE PLANET IS HOTTER THAN EVER IN RECORDED HISTORY BECAUSE OF THE CLIMATE CHANGE ISSUE. It’s obvious we will see much more of this despite the fact aviation experts tell us it’s rare.

We have the confirmation of the plane incident of Qatar Airways flight QR017 because of the turbulence over Turkey from Dublin Airport.
15.00 update:
Qatar Airways flight QR017 from Doha landed safely as scheduled at Dublin Airport shortly before 13.00 on Sunday. Upon landing, the aircraft was met by emergency services, including Airport Police and our Fire and Rescue department, due to 6 passengers and 6 crew [12 total] on board reporting injuries after the aircraft experienced turbulence while airborne over Turkey. All passengers were assessed for injury prior to disembarking the aircraft. Eight passengers were subsequently taken to hospital. The return flight to Doha (flight QR018) is scheduled to operate as normal this afternoon, albeit with a delay. Flight operations at Dublin Airport were unaffected and continue as normal this afternoon.

Humanity’s survival is still within our grasp – just. But only if we take these radical steps | David King
Reduce emissions, build resilience, repair ecosystems, remove greenhouse gases: these are the four Rs that can save us, says David King, chair of the global Climate Crisis Advisory Group

Reduce emissions, build resilience, repair ecosystems, remove greenhouse gases: these are the four Rs that can save us
Yet despite mounting evidence and urgent pleas, meaningful action falters. Global prosperity has historically emerged from fossil fuels. But the stranglehold of fossil fuel giants, generously subsidised by governments and financially backed by banks, places short-term profits over the planet’s survival. This entrenched dependency stymies efforts to transition to a sustainable future, despite the urgent need for change. GDP growth remains sacred, while climate, biodiversity, health, and social equity are sacrificed, condemning future generations to inherit a ravaged planet.
We often hear that in response to the climate crisis, we need to make sacrifices. But this framing is flawed. We must find joy in nurturing what is around us, from nature to the things we own. Fulfilment should come from quality, not quantity, and from nature, not new things.

I heard to day that something like 80% of new power-generation is from renewables, which is great. Of course, to really tackle the climate issue, we need to be replacing existing fossil-fuel generation as well.
This is important news given to us by the ESA Earth Observation Department. . The EarthCARE Satellite will be LAUNCHED SOON
The EarthCARE Satellite carries four instruments for observations of clouds and aerosols with four synergistic sensing methodologies.
The instruments provide key measurements to answer critical scientific questions related to the role that clouds and aerosols play in reflecting incident solar radiation back out to space and trapping infrared radiation emitted from Earth’s surface which are still unknown.
That's why in the quoted post Dr. James Hansen, former NASA Scientist and Director of NASA GISS, says:
"It's important to have knowledge of aerosol effects on clouds to better rule any climate policy, and we need to do it soon. Time is running short."
Dr. James Hansen
ESA EarthCARE Satellite is launching soon!
According to the tradition satellites are also given nicknames in addition to their ‘official’ names. The nickname chosen for EarthCARE is ‘Hakuryu’ or ‘White Dragon’ in Japanese.
The heatwave hitting Mexico is continuing. There has never been anything remotely close to this.
I am afraid that soon we will have another record Global Temperature Deviation for May 2024.

On May 26, 2024 the Anomaly of the Sea Surface Temperature (Black Line 20.9°C) is decreasing and getting closer to the Yellow Line representing the 2023 Anomaly of the Sea Surface Temperature.
It looks like when La Niña will kick in the Anomaly of the Sea Surface Temperature will stabilize.
But for the time being Sea Surface Temperature is still high.
Gulf Stream could collapse as early as 2025, study suggests
A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis
www.theguardian.com
The Gulf Stream system could collapse as soon as 2025, a new study suggests. The shutting down of the vital ocean currents, called the Atlantic Meridional Overturning Circulation (Amoc) by scientists, would bring catastrophic climate impacts.
Amoc was already known to be at its weakest in 1,600 years owing to global heating and researchers spotted warning signs of a tipping point in 2021.
The new analysis estimates a timescale for the collapse of between 2025 and 2095, with a central estimate of 2050, if global carbon emissions are not reduced. Evidence from past collapses indicates changes of temperature of 10C in a few decades, although these occurred during ice ages.
Other scientists said the assumptions about how a tipping point would play out and uncertainties in the underlying data are too large for a reliable estimate of the timing of the tipping point. But all said the prospect of an Amoc collapse was extremely concerning and should spur rapid cuts in carbon emissions.
Amoc carries warm ocean water northwards towards the pole where it cools and sinks, driving the Atlantic’s currents. But an influx of fresh water from the accelerating melting of Greenland’s ice cap and other sources is increasingly smothering the currents.
A collapse of Amoc would have disastrous consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South America and west Africa. It would increase storms and drop temperatures in Europe, and lead to a rising sea level on the eastern coast of North America. It would also further endanger the Amazon rainforest and Antarctic ice sheets.
“I think we should be very worried,” said Prof Peter Ditlevsen, at the University of Copenhagen in Denmark, and who led the new study. “This would be a very, very large change. The Amoc has not been shut off for 12,000 years.”
The Amoc collapsed and restarted repeatedly in the cycle of ice ages that occurred from 115,000 to 12,000 years ago. It is one of the climate tipping points scientists are most concerned about as global temperatures continue to rise.
Research in 2022 showed five dangerous tipping points may already have been passed due to the 1.1C of global heating to date, including the shutdown of Amoc, the collapse of Greenland’s ice cap and an abrupt melting of carbon-rich permafrost.
The new study, published in the journal Nature Communications, used sea surface temperature data stretching back to 1870 as a proxy for the change in strength of Amoc currents over time.
The researchers then mapped this data on to the path seen in systems that are approaching a particular type of tipping point called a “saddle-node bifurcation”. The data fitted “surprisingly well”, Ditlevsen said. The researchers were then able to extrapolate the data to estimate when the tipping point was likely to occur. Further statistical analysis provided a measure of the uncertainty in the estimate.
The analysis is based on greenhouse gas emissions rising as they have done to date. If emissions do start to fall, as intended by current climate policies, then the world would have more time to try to keep global temperature below the Amoc tipping point.
The most recent assessment by the Intergovernmental Panel on Climate Change concluded that Amoc would not collapse this century. But Ditlevsen said the models used have coarse resolution and are not adept at analysing the non-linear processes involved, which may make them overly conservative.
The potential collapse of Amoc is intensely debated by scientists, who have previously said "IT MUST BE AVOIDED AT ALL COSTS”.
Prof Niklas Boers, from the Potsdam Institute for Climate Impact Research in Germany, revealed the early warning signs of Amoc collapse in 2021. “The results of the new study sound alarming but if the uncertainties in the heavily oversimplified model [of the tipping point] and in the underlying [sea temperature] data are included, then it becomes clear that these uncertainties are too large to make any reliable estimate of the time of tipping.”
Prof David Thornalley, at University College London, UK, agreed the study had large caveats and unknowns and said further research was essential: “But if the statistics are robust and a relevant way to describe how the actual Amoc behaves, then this is a very concerning result.”
Dr Levke Caesar, at the University of Bremen, Germany, said using sea surface temperatures as proxy data for the strength of the Amoc currents was a key source of uncertainty: “We only have direct observational data of the Amoc since 2004.”
The extrapolation in the new analysis was reasonable, according to Prof Tim Lenton, at the University of Exeter, UK. He said the tipping point could lead to a partial Amoc collapse, for example only in the Labrador Sea, but that this would still cause major impacts. Ditlevsen said he hoped the debate would drive new research: “It’s always fruitful when you do not exactly agree.”
Prof Stefan Rahmstorf, at the University of Potsdam, Germany, said: “There is still large uncertainty where the Amoc tipping point is, but the new study adds to the evidence that it is much closer than we thought. A single study provides limited evidence, but when multiple approaches have led to similar conclusions this must be taken very seriously, especially when we’re talking about a risk that we really want to rule out with 99.9% certainty. Now we can’t even rule out crossing the tipping point in the next decade or two.”

Takeaways Earth Will Continue to Warm and the Effects Will Be Profound Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets...
science.nasa.gov
Takeaways
We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
Earth Will Continue to Warm and the Effects Will Be Profound
Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner.
Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.
The magnitude and rate of climate change and associated risks depend strongly on near-term mitigation and adaptation actions, and projected adverse impacts and related losses and damages escalate with every increment of global warming.
Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.
Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.
The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900.1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.
The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.
The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future.
Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports:
U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100
Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms.
Climate Changes Will Continue Through This Century and Beyond
Global climate is projected to continue warming over this century and beyond.
Hurricanes Will Become Stronger and More Intense
Scientists project that hurricane-associated storm intensity and rainfall rates will increase as the climate continues to warm.
More Droughts and Heat Waves
Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) are projected to become more intense, and cold waves less intense and less frequent.
Longer Wildfire Season
Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.
Changes in Precipitation Patterns
Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.
Frost-Free Season (and Growing Season) will Lengthen
The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.
Global Temperatures Will Continue to Rise
Summer of 2023 was Earth's hottest summer on record, 0.41 degrees Fahrenheit (F) (0.23 degrees Celsius (C)) warmer than any other summer in NASA’s record and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980.
Arctic Is Very Likely to Become Ice-Free
Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.

Wealthy white men are UK’s biggest transport polluters, study finds
IPPR research examines transport emissions by income, gender, location, ethnicity and age
www.theguardian.com
The richest 0.1% in Britain emit 22 times more from transport than low earners, and 12 times more than average. The data finds that income is directly linked to levels of mobility, with people who earn more than £100,000 travelling on average at least double the distance each year compared with those on incomes under £30,000. Those in the most deprived 10% are responsible for by far the fewest emissions, though flying still makes up more than half of their total emissions.
