The Sharm el-Sheikh Implementation Plan was gavelled through at dawn on Sunday 20 November 2022, after a two-week climate summit went into overtime. The Sharm el-Sheikh Implementation Plan made a breakthrough on support for climate victims, but avoided confronting the oil and gas sector

Procedurally, no big decisions were due to land at Cop27. But the convergence of multiple crises in 2022 – Russia’s war, global inflation, Covid’s long tail and of course climate disasters – raised the stakes of every increment. The biggest breakthrough came on support for climate victims. Developing countries got the loss and damage fund they fought for – on the proviso that the burden of paying into it does not all fall on rich governments. Who pays and who benefits is a battle for Cop28. There was little to stop polluters causing more damage, though. A proposal to phase out all fossil fuels, not just the coal power targeted at last year’s summit, went nowhere. The Egyptian presidency openly struck gas deals on the sidelines. Here’s where the key issues landed.


Fossil fuels

At last year’s Cop26 in Glasgow, the presidency made a push to “keep 1.5 alive”, referring to the most ambitious temperature limit in the Paris Agreement. And it named coal as a problem for the first time, with countries agreeing to phase down its use.

In Sharm el-Sheikh, coal-reliant India sought to turn the heat onto other fossil fuels. This was seized on by a broad coalition of more than 80 developed and vulnerable countries – but not by the Egyptian presidency. Egypt never included fossil fuel phaseout language in the draft text. Indeed, it promoted fossil gas and struck deals on the sidelines. Behind closed doors, countries including Saudi Arabia and Russia made the argument that oil doesn’t cause climate change, emissions do.

The text does promote renewables but also “low-emission” energy. This could be interpreted as gas, a fossil fuel which is less polluting when burned than coal, or fossil fuels with carbon capture and storage. It holds the Glasgow Pact line on 1.5C and coal, but doesn’t go beyond it. There is recognition that the 1.5C target “requires rapid, deep and sustained reductions in global greenhouse gas emissions reducing global net greenhouse gas emissions by 43% by 2030 relative to the 2019 level”.


Loss and damage finance

Three decades ago, small island states and poorer countries started calling for compensation for the damage climate change inflicts on their communities. While “compensation” became taboo, they finally got finance for “loss and damage” on the formal agenda at Cop27. Wealthy nations, reluctant to put their hands in their pockets, offered up a “mosaic of solutions” like insurance and early warning systems. Developing countries were determined to get a dedicated new fund.

The EU blinked first. They announced they would support a fund if the donor base was broadened, if it was targeted at the most vulnerable developing countries and if Cop27 also agreed strong action to reduce emissions. These conditions were partly met and developing nations accepted the offer. The US and other rich countries got on board and they all agreed “to establish a fund for responding to loss and damage”. 

A transitional committee will look into what funding is needed and where the money should come from. It will tackle the thorny issues of whether to expand the donor base to countries like China or Qatar and report to Cop28. Some of the money is to come through “existing funding arrangements”, like development banks or debt relief. Some from “innovative sources”, which could mean taxes on fossil fuels, aviation or shipping.

The EU specified that support should only go to “vulnerable” countries – a term for the transitional committee to define. UN Climate Change has been tasked with holding two workshops on the issue before Cop28 and reporting back. Countries agreed on how to set up an organisation called the Santiago Network which will provide technical assistance in averting, minimising and addressing loss and damage.

Mitigation work programme

At Cop26 in Glasgow, countries noted that emissions were projected to be 14% above 2010 levels in 2030. To limit global warming to 1.5C, emissions need to fall 45%. To fix that, they agreed to set up a “work programme to urgently scale up mitigation ambition and implementation in this critical decade”. 

In Sharm el-Sheikh, nations debated how to structure this work programme. Developed and vulnerable countries wanted the talks to be long, strong and specific. Emerging economies wanted them to be short, weak and broad. The latter’s fingerprints are on text saying the process should be “non-prescriptive, non-punitive, facilitative, respectful of national sovereignty and national circumstances” and “not result in new targets or goals”. They former group wanted talks to continue until 2030, the latter until only 2023 or 2024. They compromised on 2026.


The Bridgetown agenda

A serious conversation about shifting trillions of dollars into green and climate-resilient investments has been gathering traction over the past year.  Barbados’ Mia Mottley set the ball rolling in Glasgow. Since then, her “Bridgetown agenda has gathered momentum. The proposed reforms to the international financial system are happening outside UN Climate Change. But unlocking much-needed climate finance is relevant to the process. The International Energy Agency estimates that $4 trillion need to be invested in renewable energy every year by 2030 to reach net zero emissions by 2050. Developing countries alone need an estimated $5.6 trillion to meet their 2030 goals. Increasing debt levels is making matters worse. Countries agreed that delivering such funding will require “a transformation of the financial system and its structures”.

They called on multilateral development banks (MDBs) and international financial institutions to scale up and simplify access to climate finance and ensure their activities contribute to “significantly increasing climate ambition”. This echoes recommendations made by a G20 expert group on the issue.

However, Mottley’s flagship proposal to use IMF relief, known as special drawing rights (SDRs), to fund carbon-cutting projects doesn’t feature in the text. Discussions will continue at the spring meetings of the IMF and the World Bank.


Carbon trading rules

Negotiators outlined the broad framework for a new global carbon trading scheme in Glasgow. In Sharm el-Sheikh, they filled in some details. The text creates a two-tier carbon market, applying different rules depending on who buys the credits and for what purpose. The Glasgow Pact banned double counting: if one country buys an emission credit from another to use towards its target, the host country needs to make an accounting adjustment. This also applies to international compliance markets such as aviation’s trading scheme Corsia. 

In the new second-tier market, carbon credits are called “mitigation contributions”. A company can buy a credit from another country and the host does not need to tweak its emissions inventory. While the name suggests the buyer should not use these credits to offset their own emissions, there is nothing to stop them. Campaigners warn this opens the door to double claiming and corporate greenwashing of net zero pledges.

A technical body made recommendations on how to define “removals” – sucking carbon dioxide out of the air – for trading purposes. Many of the options involve untested or controversial processes and negotiators sent the recommendations back for further work. Regarding bilateral carbon trades between countries, the text allows governments to designate any information about the exchange as confidential. Experts have raised concerns this could allow shady deals to go unchecked and make accountability toothless.


Just energy transition

The energy crisis has been the stark background for Cop27. A number of countries have ramped up their coal, oil and gas production to deal with the short-term supply crunch.  In Sharm el-Sheikh, countries “recognised” that the crisis underlines the need to “rapidly transform energy systems,” including by accelerating renewable energy roll out.  

Deals between rich and emerging economies to accelerate the shift away from coal, known as just energy transition partnerships, got a special mention as a way to speed up emission cuts. Two days before the start of the summit, South Africa published details of a $84bn investment plan to transition from coal clean energy. It outlined long-awaited details of a $8.5bn deal with wealthy countries

On the sidelines of the G20 leaders’ summit in Bali, rich countries announced a similar $20bn deal with Indonesia. The funds include both public and private finance contributions. Vietnam is next in line, with an agreement mooted before the end of the year. At Cop27, countries agreed that “just and equitable energy transition” must be based on national development priorities and include social protection and solidarity measures, such as providing retraining programmes and support for coal workers affected by the transition.  Cop27 decided to establish a work programme on “just transition” and convene an annual ministerial roundtable as part of this process.


Adaptation

A year ago, Egypt billed Cop27 as a “resilience” Cop. That buzzword was later dropped for “implementation”.  Adapting to the impacts of a changing climate never stopped being important to those on the front lines. But measuring progress on adaptation is harder than counting tonnes of carbon. Work to define the Global Goal on Adaptation inched forward. Countries agreed to develop a framework to guide delivery of the goal and track progress. This will take into account countries’ vulnerability and capacity to cope, consider a range of themes include water, food and agriculture and poverty, and science-based indicators, metrics and targets. 

A proposal to commission a special report on adaptation from the Intergovernmental Panel on Climate Change went nowhere. Frustrated negotiators from both developed and developing countries told Climate Home the African Group of Negotiators (AGN) hogged the mic with unproductive interventions. 

Mariam Allam, lead AGN negotiator on the issue, rebutted the accusation. On the contrary, she said the AGN’s “willingness” to engage with the substance “was unmatched” by other groups.  Richard Klein, an adaptation expert at the Stockholm Environment Institute, told Climate Home: “There was an opportunity to show what ambitious and transformative adaptation could look like. But it didn’t happen.” 

It doesn’t help that this agenda is poorly funded. Countries “noted with serious concern” the gap between current levels of adaptation finance and what is needed to responded to climate impacts. They “urged” countries to “urgently and significantly scale up their provision of climate finance”. The only mention of a pledge by rich countries to double adaptation funding to $40bn by 2025 was about preparing a report.


Climate finance

Rich countries are late to deliver the $100 billion they promised by 2020 to help developing countries cut emissions and cope with climate impacts. The definition of madness is doing the same thing over and over again and expecting different results. So perhaps it shouldn’t surprise that talks on a new collective climate finance goal for 2025 got off to a slow start. A decision is not due until 2024 and the Cop27 text is mostly proceduralOne developing country negotiator likened the process to growing grapes. Harvesting fruits too early doesn’t make good wine, he said. The text agreed in Sharm says the new goal will “take into account the needs and priorities of developing countries”.

It is not just about quantity but quality. Contributors prefer to lend money for carbon-cutting projects, “mobilising” private finance where possible. Recipients want public grants, particularly for unprofitable, but essential, adaptation projects. Much of the debate will centre on sub-targets and accounting standards. Developed countries are pushing to expand the donor base when it comes to loss and damage funding. It’s only a matter of time before that flares up in the broader finance talks.


Africa’s ‘special needs and circumstances’

African nations had hoped that the “Africa Cop” would recognise its special needs and circumstances to tackle climate action. The status unlocks priority access to international support and is enjoyed by the least developed countries (LDC), which includes 33 African nations, and small island developing states (SIDS).  But a proposal by the African Group of Negotiators was once again rejected.  

A group of Latin American and Caribbean nations (Ailac) has repeatedly argued that expanding the special needs status to all African countries should allow them to claim it too. Chile, on behalf of a group of Latin American and Caribbean nations (Ailac), proposed to open a space for different groups and regions to discuss their needs. There was no consensus on the proposal.

EARTH DAY 2024: Packaging Is the Biggest Driver of Global Plastics Use

Published

Earth Day, celebrated annually on April 22, marks a global commitment to environmental protection and sustainability. The first Earth Day took place in 1970, ignited by U.S. Senator Gaylord Nelson of Wisconsin, who aimed to raise awareness about environmental issues and mobilize action to address them. Since then, Earth Day has evolved into a worldwide movement, engaging millions of people across the globe in activities such as tree planting, clean-up campaigns and advocacy for environmental policies. Its organizer is EARTHDAY.ORG, a non-profit organization dedicated to promoting environmental conservation and mobilizing communities to take action for a healthier planet.

The theme of this year’s Earth Day is “Planet vs. Plastics” – a theme chosen to raise awareness of the damage done by plastic to humans, animals and the planet and to promote policies aiming to reduce global plastic production by 60 percent by 2040.

As our chart shows, global plastics use has increased rapidly over the past few decades, growing 250 percent since 1990 to reach 460 million tonnes in 2019, according to the OECD’s Global Plastics Outlook, which projects another 67-percent increase in global plastics use by 2040 and for the world’s annual plastic use to exceed one billion tonnes by 2052. As our chart shows, packaging is the largest driver of global plastics use, which is why a rapid phasing out of all single use plastics by 2030 is one of the policy measures proposed under EARTHDAY.ORG’s 60X40 framework.

Other major applications of plastics include building and construction, transportation as well as textiles, with the fast fashion industry particularly guilty of adding to the world’s plastic footprint. “The fast fashion industry annually produces over 100 billion garments,” the Earth Day organizers write. “Overproduction and overconsumption have transformed the industry, leading to the disposability of fashion. People now buy 60 percent more clothing than 15 years ago, but each item is kept for only half as long.” Most importantly, the organization points out that 85 percent of disposed garments end up in landfills or incinerators, while just 1 percent are being recycled.

The Sahara Desert used to be a Green Savannah – New Research Explains Why

Published

Spread the love

By Edward Armstrong

Algeria’s Tassili N’Ajjer plateau is Africa’s largest national park. Among its vast sandstone formations is perhaps the world’s largest art museum. Over 15,000 etchings and paintings are exhibited there, some as much as 11,000 years old according to scientific dating techniques, representing a unique ethnological and climatological record of the region.

Curiously, however, these images do not depict the arid, barren landscape that is present in the Tassili N’Ajjer today. Instead, they portray a vibrant savannah inhabited by elephants, giraffes, rhinos and hippos. This rock art is an important record of the past environmental conditions that prevailed in the Sahara, the world’s largest hot desert.

These images depict a period approximately 6,000-11,000 years ago called the Green Sahara or North African Humid Period. There is widespread climatological evidence that during this period the Sahara supported wooded savannah ecosystems and numerous rivers and lakes in what are now Libya, Niger, Chad and Mali.

This greening of the Sahara didn’t happen once. Using marine and lake sediments, scientists have identified over 230 of these greenings occurring about every 21,000 years over the past eight million years. These greening events provided vegetated corridors which influenced species’ distribution and evolution, including the out-of-Africa migrations of ancient humans.

These dramatic greenings would have required a large-scale reorganisation of the atmospheric system to bring rains to this hyper arid region. But most climate models haven’t been able to simulate how dramatic these events were.

As a team of climate modellers and anthropologists, we have overcome this obstacle. We developed a climate model that more accurately simulates atmospheric circulation over the Sahara and the impacts of vegetation on rainfall.

We identified why north Africa greened approximately every 21,000 years over the past eight million years. It was caused by changes in the Earth’s orbital precession – the slight wobbling of the planet while rotating. This moves the Northern Hemisphere closer to the sun during the summer months.

This caused warmer summers in the Northern Hemisphere, and warmer air is able to hold more moisture. This intensified the strength of the West African Monsoon system and shifted the African rainbelt northwards. This increased Saharan rainfall, resulting in the spread of savannah and wooded grassland across the desert from the tropics to the Mediterranean, providing a vast habitat for plants and animals.

Our results demonstrate the sensitivity of the Sahara Desert to changes in past climate. They explain how this sensitivity affects rainfall across north Africa. This is important for understanding the implications of present-day climate change (driven by human activities). Warmer temperatures in the future may also enhance monsoon strength, with both local and global impacts.

Earth’s changing orbit

The fact that the wetter periods in north Africa have recurred every 21,000 years or so is a big clue about what causes them: variations in Earth’s orbit. Due to gravitational influences from the moon and other planets in our solar system, the orbit of the Earth around the sun is not constant. It has cyclic variations on multi-thousand year timescales. These orbital cycles are termed Milankovitch cycles; they influence the amount of energy the Earth receives from the sun.

On 100,000-year cycles, the shape of Earth’s orbit (or eccentricity) shifts between circular and oval, and on 41,000 year cycles the tilt of Earth’s axis varies (termed obliquity). Eccentricity and obliquity cycles are responsible for driving the ice ages of the past 2.4 million years.

The third Milankovitch cycle is precession. This concerns Earth’s wobble on its axis, which varies on a 21,000 year timescale. The similarity between the precession cycle and the timing of the humid periods indicates that precession is their dominant driver. Precession influences seasonal contrasts, increasing them in one hemisphere and reducing them in another. During warmer Northern Hemisphere summers, a consequent increase in north African summer rainfall would have initiated a humid phase, resulting in the spread of vegetation across the region.

Eccentricity and the ice sheets

In our study we also identified that the humid periods did not occur during the ice ages, when large glacial ice sheets covered much of the polar regions. This is because these vast ice sheets cooled the atmosphere. The cooling countered the influence of precession and suppressed the expansion of the African monsoon system.

The ice ages are driven by the eccentricity cycle, which determines how circular Earth’s orbit is around the sun. So our findings show that eccentricity indirectly influences the magnitude of the humid periods via its influence on the ice sheets. This highlights, for the first time, a major connection between these distant high latitude and tropical regions.

The Sahara acts as a gate. It controls the dispersal of species between north and sub-Saharan Africa, and in and out of the continent. The gate was open when the Sahara was green and closed when deserts prevailed. Our results reveal the sensitivity of this gate to Earth’s orbit around the sun. They also show that high latitude ice sheets may have restricted the dispersal of species during the glacial periods of the last 800,000 years.

Our ability to model the African humid periods helps us understand the alternation of humid and arid phases. This had major consequences for the dispersal and evolution of species, including humans, within and out of Africa. Furthermore, it provides a tool for understanding future greening in response to climate change and its environmental impact.

Refined models may, in the future, be able to identify how climate warming will influence rainfall and vegetation in the Sahara region, and the wider implications for society.

COP28: New Draft Text on Climate Deal Published; Calls for Transitioning away from Fossil Fuels

Published

Spread the love

By Imogen Lillywhite,

A new draft text on global stocktake has been published at the UN climate summit, COP28 UAE, on Wednesday morning. While the draft text does not contain the words “phase out”, it includes reference to transitioning away from all fossil fuels to enable the world to reach net zero by 2050.

The text published by the UN’s climate body calls on parties to accelerate and substantially reduce non-carbon dioxide emissions worldwide with a focus on reducing methane emissions by 2030. “We all want to get the most ambitious outcome possible,” Majid Al Suwaidi, COP28 Director-General, said on Tuesday.

The text, published early Wednesday, does not specifically refer to oil, but mentions the need to ‘phase-down’ coal.  It says that it recognises the need for ‘deep, rapid and sustained reductions in greenhouse gas emissions in line with 1.5C pathways and calls on Parties to contribute to global efforts.

Among those efforts it recognises the need to triple renewable energy capacity by 2030 and doubling the annual rate of energy efficiency improvements by the same date. It also recognises the need to accelerate the phase-down of coal and accelerate towards net zero energy systems, utilising zero or low carbon fuels by mid century.

While the document does not mention oil or combustion engines, it does recognises the need for accelerating the reduction of emissions from road transport on a range of pathways, including through development of infrastructure and rapid deployment of zero and low-emission vehicles. It also recognises the need to phase out inefficient fossil fuel subsidies that do not address energy poverty or just transitions, as soon as possible.

Finance specifics

On the subject of finance, the document said developed countries should continue to take the lead in mobilising climate finance from a wide variety of sources, instruments and channels, noting the significant role of public funds, through a variety of actions, including supporting country-driven strategies, and taking into account the needs and priorities of developing countries.

Such mobilisation of climate finance should represent a progression beyond previous efforts, the text said. It may provide small comfort to campaigners from developing countries who implored Parties to begin the phase out of fossil fuels and provide vastly improved access to funding for renewables.

The document highlights the persistent gap and challenges in technology development and transfer and the uneven pace of adoption of climate technologies around the world.

It further urges Parties to address these barriers and strengthen cooperative action, including with non-Party stakeholders, particularly with the private sector, to rapidly scale up the deployment of existing technologies, the fostering of innovation and the development and transfer of new technologies.

It also emphasizes the ongoing challenges faced by many developing country Parties in accessing climate finance and encourages further efforts, including by the operating entities of the Financial Mechanism, to simplify access to such finance, in particular for those developing country Parties that have significant capacity constraints, such as the least developed countries and small island developing States.
