Key UN reports published warn urgent and collective action needed

Key UN reports published warn urgent and collective action needed – as oil firms report astronomical profits

By Damian Carrington Environment editor

The climate crisis has reached a “really bleak moment”, one of the world’s leading climate scientists has said, after a slew of major reports laid bare how close the planet is to catastrophe.

Collective action is needed by the world’s nations more now than at any point since the second world war to avoid climate tipping points, Prof Johan Rockström said, but geopolitical tensions are at a high.

He said the world was coming “very, very close to irreversible changes … time is really running out very, very fast”.

Emissions must fall by about half by 2030 to meet the internationally agreed target of 1.5C of heating but are still rising, the reports showed – at a time when oil giants are making astronomical amounts of money.

On Thursday, Shell and TotalEnergies both doubled their quarterly profits to about $10bn. Oil and gas giants have enjoyed soaring profits as post-Covid demand jumps and after Russia’s invasion of Ukraine. The sector is expected to amass $4tn in 2022, strengthening calls for heavy windfall taxes to address the cost of living crisis and fund the clean energy transition.

All three of the key UN agencies have produced damning reports in the last two days. The UN environment agency’s report found there was “no credible pathway to 1.5C in place” and that “woefully inadequate” progress on cutting carbon emissions means the only way to limit the worst impacts of the climate crisis is a “rapid transformation of societies”.

Current pledges for action by 2030, even if delivered in full, would mean a rise in global heating of about 2.5C, a level that would condemn the world to catastrophic climate breakdown, according to the UN’s climate agency. Only a handful of countries have ramped up their plans in the last year, despite having promised to do so at the Cop26 UN climate summit in Glasgow last November.

The UN’s meteorological agency reported that all the main heating gases hit record highs in 2021, with an alarming surge in emissions of methane, a potent greenhouse gas.

Separately, the IEA’s world energy report offered a glimmer of progress, that CO2 from fossil fuels could peak by 2025 as high energy prices push nations towards clean energy, though it warned that it would not be enough to avoid severe climate impacts.

Rockström, director of the Potsdam Institute for Climate Impact Research in Germany, said: “It’s a really bleak moment, not only because of the reports showing that emissions are still rising, so we’re not delivering on either the Paris or Glasgow climate agreements, but we also have so much scientific evidence that we are very, very close to irreversible changes – we’re coming closer to tipping points.”

Research by Rockström and colleagues, published in September, found five dangerous climate tipping points may already have been passed due to the global heating caused by humanity to date, including the collapse of Greenland’s ice cap, with another five possible with 1.5C of heating.

“Furthermore, the world is unfortunately in a geopolitically unstable state,” said Rockström. “So when we need collective action at the global level, probably more than ever since the second world war, to keep the planet stable, we have an all-time low in terms of our ability to collectively act together.”

“Time is really running out very, very fast,” he said. “I must say, in my professional life as a climate scientist, this is a low point. The window for 1.5C is shutting as I speak, so it’s really tough.”

His remarks came after the UN secretary general, António Guterres, said on Wednesday that climate action was “falling pitifully short”. “We are headed for a global catastrophe [and] for economy-destroying levels of global heating.”

He added: “Droughts, floods, storms and wildfires are devastating lives and livelihoods across the globe [and] getting worse by the day. We need climate action on all fronts and we need it now.” He said the G20 nations, responsible for 80% of emissions, must lead the way.

Inger Andersen, head of the UN environment program (UNEP), told the Guardian that the energy crisis must be used to speed up delivery of a low-carbon economy: “We are in danger of missing the opportunity and a crisis is a terrible thing to waste.”

Presidential Pardons

Presidential Pardons

While most of what our founders penned in the Constitution is inspired, I suspect they could have had more forethought regarding the power of the pardon. This power is provided in section 2, clause 1.

Section 2 Powers (of the President)

  • Clause 1 Military, Administrative, and Clemency
    • “The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.”

While the “impeachment” exception was a good addition we would be well served if cases involving “relatives” and “associates” were also excluded.

Sodium Battery Update

Sodium Battery Update

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-power hybrid sodium-ion battery that can be charged in seconds. 

Sodium is considered nearly 1000 times more abundant than lithium. Therefore, sodium-ion electrochemical energy storage devices are more appealing than traditional lithium-ion electrochemical energy storage.

Led by Professor Jeung Ku Kang from the Department of Materials Science and Engineering, the research team integrated anode materials typically used in batteries with cathodes suitable for supercapacitors.

The combination helped the battery to achieve high storage capacities and rapid charge-discharge rates. The study indicates that the battery can be a viable next-generation alternative to lithium-ion batteries.                                                                                    

Hybrid sodium-ion energy storage device

Comprising the newly developed anode and cathode, the assembled full cell forms a high-performance hybrid sodium-ion energy storage device, which crosses the energy density of commercial lithium-ion batteries available in the market. According to researchers, the device exhibits the characteristics of supercapacitors’ power density.

“The development of a hybrid battery with high energy and high power density requires an improvement to the slow energy storage rate of battery-type anodes as well as the enhancement of the relatively low capacity of supercapacitor-type cathode materials,” said the team in a statement.                                                                                                                                                        

Sodium batteries can fulfill an increasing demand

Salt batteries: https://www.msn.com/en-us/money/technology/scientists-make-breakthrough-in-production-of-salt-based-battery-technology-this-process-makes-it-easier/ar-AA1nF2YR?ocid=msedgntp&pc=U531&cvid=f94d02a42bd34c7dab303c7464fd9352&ei=15

The battery may fulfill an increasing demand for low-cost electrochemical energy storage devices with high energy density for prolonged operation on a single charge and fast-chargeable power density to meet a wide range of applications ranging from mobile electronic devices through electric vehicles (EVs) to large-scale grid systems.

Currently, available Sodium-ion energy storage systems are poor in rechargeability as they have a low power density while providing a relatively high energy density. Currently, two types of sodium storage systems are available, sodium-ion batteries (SIBs) and sodium-ion capacitors (SICs). Therefore, researchers focused on sodium-ion hybrid energy storage (SIHES) cells. 

SIHES can use the different potential windows of capacitor-type cathodes and battery-type anodes. It has attracted a lot of attention because this storage system, in principle, could simultaneously allow high energy density and fast-rechargeable power density.

According to researchers, the SIHES can achieve an energy density of 247 Wh/kg and a power density of 34,748 W/kg. Professor Kang said that the research represents a breakthrough in overcoming the current limitations of energy storage systems. He anticipates broader applications across various electronic devices, including electric vehicles.

It’s likely to be useful for rapid charging applications ranging from electric vehicles to smart electronic devices and aerospace technologies.

Co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, the study was published in the journal Energy Storage Materials.

A significant advancement in battery technology could soon revolutionize smartphone and electric vehicle technologies. Researchers have developed a new sodium-based battery capable of recharging in seconds, providing a promising alternative to current lithium-ion batteries.

Sodium batteries aren’t new and have historically had many drawbacks. Scientists have combined materials for anodes from conventional batteries with cathodes from supercapacitors, creating a new type of sodium-ion battery distinguished by high capacity and rapid recharge capabilities.

Sodium, being far more abundant than lithium, makes these new batteries potentially less expensive and more sustainable. However, previous sodium-ion batteries had lower performance in terms of power and energy storage capacity compared to lithium-ion batteries and required longer charging times, limiting their applications.

In this new study, researchers aimed to overcome these shortcomings. They developed an innovative type of anode with ultrafine iron sulfide particles integrated within sulfur-doped carbon and graphene, thereby enhancing conductivity and energy storage. For the cathode, they used a “zeolitic imidazolate framework” (ZIF), a porous crystalline structure that combines metallic ions with organic molecules, thus improving the battery’s charge and discharge speed.

The complete prototype achieved an energy storage capacity of 247 watt-hours per kilogram (Wh/kg) and could deliver power up to 34,748 watts per kilogram (W/kg), far surpassing existing technology. Additionally, the battery maintained its efficiency and performance over more than 5,000 charge and discharge cycles, suggesting enhanced longevity critical for applications such as energy storage on the electrical grid and electric vehicles.
