Please let me disagree with Climate Activist of Letze Generation.
By blocking trucks and cars you will not certainly work out the Climate Change issue. You will only make drivers angry. Believe me!

Weather vs climate: What's the difference?

Although they are closely related, weather and climate are not the same. The difference between weather and climate is simply a matter of time. Weather refers to the short-term conditions of the atmosphere, while climate describes the average weather conditions over a long period of time.

The NASA Earth Observation Department says that Sea Ice at Earth’s poles continued declining in 2024.
This means that the Earth's albedo (reflectivity) is lowering and we have a further Energy Imbalance adding to that already produced by the GHE. That's why the Global Temperature Deviation is increasing.

Looks like the farmers have torpedoed the EU environment agreement

EU nature restoration laws face collapse as member states withdraw support

Brussels vote cancelled after it became clear law would not pass final stage with majority vote

www.theguardian.com

The EU’s nature restoration laws appear on the verge of collapse after eight member states, including Hungary and Italy, withdrew support for the legislation. The laws, which have been two years in the making and are designed to reverse decades of damage to wildlife on land and in waterways, were supposed to be rubber-stamped in a vote on Monday.

representative of one member state that is not supporting the bill said on Monday nothing would change its mind. “We can’t tell our farmers: ‘We got everything you asked for’ in terms of concessions from Brussels one day and reintroduce burdens for farmers the next.

The World Meteorological Office (WMO) is reminding us the meaning of "NET ZERO".

"Achieving NET ZERO means balancing carbon dioxide emissions with removal efforts, like creating carbon sinks, to halt increases in greenhouse gas concentrations."

While Carbon ZERO means same Carbon Dioxide emitted and same Carbon Dioxide absorbed without removal efforts.

Of course we are aiming to get NET ZERO all over the world.

Most carbon removal projects are ineffective.
The only effective carbon removal method is allowing the land to rewild.
Just stop burning stuff.

‘Tone-deaf’ fossil gas growth in Europe is speeding climate crisis, say activists

Just 2% of continent’s gas capacity has planned retirement date despite pledges to decarbonise, study shows

www.theguardian.com

Europe’s “tone-deaf” expansion of fossil gas is accelerating climate breakdown and increasing reliance on hostile regimes, campaigners have warned. Just four of Europe’s gas-fired power plants have a retirement plan and new projects will increase the continent’s gas generation capacity by 27%, according to analysis from the campaign group Beyond Fossil Fuels. It argues that the dash for gas contradicts the International Energy Agency’s recommendation that rich countries decarbonise their electricity grids in the next 10 years to stop the planet from heating 1.5C.

The extra capital costs of capturing carbon from a gas plant are so high that “to make it worth it, you would have to run it all the time”, said Bataille. “You can’t use it as a following unit to balance wind and solar.” While it “might be legitimate” to use fossil gas with carbon capture in places with no alternative sources of clean, firm power, he added, advances in battery technology were making that less likely.

“The case for fossil CCS in power keeps getting smaller and smaller.”

Latest daily reading for atmospheric CO2 is 426.35 ppm (for Mar. 24, 2024).
Up 5.40 ppm from 420.95 on Mar. 26, 2023 (NOAA Source).

Wish to remind that the Equivalent atmospheric CO2 (Considering all GHGs mentioned in the quoted post) is today 560 ppm!

This post is worrisome so please don't look it up.

Earth's rotation is changing because of melting polar ice

"Global warming is already affecting global timekeeping," researcher Duncan Agnew said.

www.newsweek.com

Melting ice at the poles due to climate change may impact the Earth's spin, altering our global clock.

According to a new paper in the journal Nature, the "leap second" due to be added to Coordinated Universal Time (UTC) in 2026 may now be delayed until 2029, thanks to melting polar caps.

This may impact computer networks around the globe and could be a portent of what is to come with continued climate change and sea ice melting.

The angular speed of the Earth is changing because of the sea ice melting caused by the Climate Change issue and this will affect the global clock. This is another drawback of the Climate Change issue!

EU emissions keep falling!

The EU economy greenhouse gas emissions fell by -7.1% in the third quarter of 2023, all while its GDP (Gross Domestic Product) remained stable.

Happy that Italy reduced GHG emissions by -5% in a year while keeping its GDP constant.

This is the way to go. GHG emissions have to be carefully monitored for each Country all over the world IMHO.

‘Ecocide in Gaza’: does scale of environmental destruction amount to a war crime?

Exclusive: Satellite analysis revealed to the Guardian shows farms devastated and nearly half of the territory’s trees razed. Alongside mounting air and water pollution, experts says Israel’s onslaught on Gaza’s ecosystems has made the area unlivable

www.theguardian.com

The full extent of the damage in Gaza has not yet been documented, but analysis of satellite imagery provided to the Guardian shows the destruction of about 38-48% of tree cover and farmland. Olive groves and farms have been reduced to packed earth; soil and groundwater have been contaminated by munitions and toxins; the sea is choked with sewage and waste; the air polluted by smoke and particulate matter. Researchers and environmental organisations say the destruction will have enormous effects on Gaza’s ecosystems and biodiversity. The scale and potential long-term impact of the damage have led to calls for it to be regarded as “ecocide” and investigated as a possible war crime.

Copernicus online portal offers terrifying view of climate emergency

Looking at the mass of information, there is only one conclusion: we are running out of time

www.theguardian.com

There is so much information on the newly launched Copernicus Climate Change Service atlas that my laptop started to overheat trying to process it all. As well as all the past data, it predicts where the climate is going and how soon we will breach the 1.5C “limit”, and then 2C. You can call up the region where you live, so it is specific to what is happening to you and your family – and all the more disturbing for that. A separate part called Climate Pulse intended particularly for journalists is easier to operate. The refreshing bit is that the maps, charts and timelines from 1850 to the present day on the main atlas are entirely factual measurements, so there can be no argument on the trends. It then follows those trends into the likely scenarios for the next few years. Examining current temperature increases, it seemed to this observer that scientists have been underestimating for some time how quickly the situation is deteriorating.

Actually in last 12 months we already overtook the threshold of 1.5°C and as Dr. Gavin Schmidt, Director of NASA GISS, said we don't have reasons to explain 0.2°C of the current Global Temperature Deviation.
We are waiting for El Niño to be replaced by ENSO neutral in August to see if the anomaly stabilizes or not.

About this matter I would like to point out that the spirit of the threshold of 1.5°C for the Global Temperature Deviation set by the Agreement of Paris was that of a threshold NEVER TO BE OVERTAKEN independently by any fact.
I mean that if also the anomaly of the Global Temperature Deviation will stabilize in August when El Niño will be replaced by ENSO neutral the threshold of 1.5°C set by the Agreement of Paris has been overtaken ANYWAY.
Hope that the UN will intervene in this matter because, as I said, from a FORMAL AND SUBSTANTIAL point of view the Global Temperature Deviation has overtaken the threshold of 1.5°C set by the Agreement of Paris.

In the reported graph we have the IPCC (Intergovernmental Panel on Climate Change) climate model projections compared against latest (Berkeley Earth) Global Temperature Observations.
The Observations confirm the predicted by IPCC steady warming.

The warming will continue as long as carbon emissions continue.

THAT'S ENTIRELY UP TO US.

Anthropogenic forcing has increased the risk of longer-traveling and slower-moving large contiguous heatwaves

Heatwaves are consecutive hot days with devastating impacts on human health and the environment. These events may evolve across both space and time, characterizing a spatiotemporally contiguous propagation pattern that has not been fully understood. Here, we track the spatiotemporally contiguous heatwaves in both reanalysis datasets and model simulations and examine their moving patterns (i.e., moving distance, speed, and direction) in different continents and periods. Substantial changes in contiguous heatwaves have been identified from 1979 to 2020, with longer persistence, longer traveling distance, and slower propagation. These changes have been amplified since 1997, probably due to the weakening of eddy kinetic energy, zonal wind, and anthropogenic forcing. The results suggest that longer-lived, longer-traveling, and slower-moving contiguous heatwaves will cause more devastating impacts on human health and the environment in the future if greenhouse gas emissions keep rising and no effective measures are taken immediately. Our findings provide important implications for the adaption and mitigation of globally connected extreme heatwaves.

Newly uncovered history of a key ocean current carries a warning on climate

<p>An international research team has used sediment cores from the planet's roughest and most remote waters to chart the long-term history of the world's most powerful ocean current, and its relationship to climate. Their key discovery: During past natural climate swings, the Antarctic...

www.eurekalert.org

It carries more than 100 times as much water as all the world's rivers combined. It reaches from the ocean's surface to its bottom, and measures as much as 2,000 kilometers across. It connects the Indian, Atlantic and Pacific oceans, and plays a key role in regulating global climate. Continuously swirling around the southernmost continent, the Antarctic Circumpolar Current (ACC) is by far the world's most powerful and consequential mover of water. In recent decades it has been speeding up, but scientists have been unsure whether that is connected to human-induced global warming, and whether the current might offset or amplify some of warming's effects.

In a new study, an international research team used sediment cores from the planet's roughest and most remote waters to chart the ACC's relationship to climate over the last 5.3 million years. Their key discovery: During past natural climate swings, the current has moved in tandem with Earth's temperature, slowing down during cold times and gaining speed in warm ones―speedups that abetted major losses of Antarctica's ice. This suggests that today's speedup will continue as human-induced warming proceeds. That could hasten the wasting of Antarctica's ice, increase sea levels, and possibly affect the ocean's ability to absorb carbon from the atmosphere.

Analysis: New oil and gas projects since 2021 could emit 14bn tonnes of CO2 - Carbon Brief

Burning all the oil and gas from new discoveries and newly approved projects since 2021 would emit at least 14.1bn tonnes of carbon dioxide

www.carbonbrief.org

Burning all the oil and gas from new discoveries and newly approved projects since 2021 would emit at least 14.1bn tonnes of carbon dioxide (GtCO2), according to Carbon Brief analysis of Global Energy Monitor (GEM) data.

This would be equivalent to more than an entire year’s worth of China’s emissions.

It includes 8GtCO2 from new oil and gas reserves discovered in 2022-23 and another 6GtCO2 from projects that were approved for development over the same period.

These have all gone ahead since the International Energy Agency (IEA) concluded, in 2021, that “no new oil and gas fields” would be required if the world were to limit global warming to 1.5°C.

That's why I think that, if we want to limit global warming to 1.5°C, the UN have to intervene in this matter of the Climate Change issue.
