2 degrees, 2.5, 3 degrees, 4 – 2023 yet another “last chance” for the climate?

Why 2023 will be another key year for the future of our climate.

I am looking out onto a sparkling white landscape, glittering frosted trees, a stunning blue winter sky in a rare white December here in the mild Rhineland of western Germany. A welcome, seasonal freeze-up after a summer that was hot – and way too dry. It would be all too easy to give way to the illusion that things are as they always were – or at least as they used to be in our memories. When the seasons were set in their ways and the winter in our part of the globe was cold and frosty. And climate change had not become a topic of everyday conversation – and a crisis threatening our future.

If only. People up in the high north of our planet will be having different thoughts this winter. At the beginning of December, the temperature in Utqiagvik, Alaska’s northernmost community (formerly known as Barrow), hit 4.4 degrees Celsius (40 degrees Fahrenheit). This is the warmest that region has seen on record from late October to late April, according to Rick Thoman, a climate specialist at the International Arctic Research Center at the University of Alaska Fairbanks, talking to AP News.

The first weekend in December, the Arctic as a whole averaged 6.4 degrees Celsius (11.5 degrees F.) warmer than the 1979-2000 average temperature.

Greenland also experienced summer temperatures in December.

This “freak” warmth is actually in line with a trend:

This year’s Arctic Report Card, issued annually at this time by NOAA since 2006, confirms the transformation of our icy northern regions as the new normal:

 “Shifting seasons and climate-driven disturbances, such as wildfires, extreme weather, and unusual wildlife mortality events, are becoming increasingly difficult to assess within the context of what has been previously considered normal”, the experts write.

The Report Card looks at the current state of different components of the Arctic environmental system relative to historical records.

The whole planet is heating up

Carbon Brief recently published its latest quarterly “state of the climate” analysis by Dr. Zeke Hausfather. He concluded that “2022 is on track to be somewhere between the fourth and sixth warmest year on record”.

This year has been one of extremes, featuring record-shattering summer heatwaves and devastating floods. Western Europe and parts of Asia have had their warmest year on record so far (from January through October), Hausfather writes. The high global average temperature for 2022 occurred despite persistent La Niña conditions in the tropical Pacific, which are having a cooling influence on global temperatures.

Although it does not set a new global temperature record, 2022 will still be one of the warmest years since records began in the late 1800s. Carbon Brief says temperatures will end up around the level expected by climate models and are consistent with the long-term warming trend over the past 50 years.

Greenhouse gas concentrations reached a new high in 2022. That means our human emissions from fossil fuels, land-use change and agriculture have increased atmospheric concentrations of CO2, methane and nitrous oxide to their highest levels in at least a few million years – if not longer, concludes Carbon Brief.

Nearly all of western Europe and large areas of China experienced their warmest January-October period ever recorded. The same is true of Iran, Afghanistan, Pakistan, Nepal and the Antarctic Peninsula. In Pakistan, these record-warm temperatures have been accompanied by catastrophic flooding that affected more than 33 million people, destroyed 1.7 million homes, and led to nearly 1,400 deaths, writes Hausfather.

Antarctic sea ice extent set new record lows during both spring and summer. Arctic sea ice remained at the low end of the historical range.

COP27 – another conference that didn’t save the world

In contrast to the increasingly visible urgency of the need to reduce emissions, this year’s UN climate conference in Sharm el-Sheikh in Egypt did little to move things on. There was one major – and long overdue – positive outcome. Developing countries finally secured a new fund for “loss and damage” resulting from climate change. Small island states and other vulnerable nations had been fighting for this for decades.  Back in Copenhagen in 2009 the industrialised countries promised to mobilize 100 billion US dollars a year from 2020 on in financial support for climate protection and adaptation measures in the developing world. That promise was not kept. Against that background, the agreement can be considered a breakthrough. However, decisions on actual amounts and which countries will actually be paying into the fund were put off until COP28 – to be held in Dubai.

This was the first COP after the publication of the latest reports by all three IPCC working groups. These underlined once more the urgent need for the world’s decision-makers to prioritize climate action.  But aside from that milestone on the path towards helping developing countries that have become victims of climate change, the Sharm el-Sheikh meeting made no progress on scaling up efforts to make the drastic cuts to emissions that we need to tackle the climate emergency.

“Together for just, ambitious implementation” was the motto. The COP was supposed to negotiate how the Paris Agreement is to be put into action. In fact the outcome did little to advance efforts to stay below 1.5C, beyond what was agreed at COP26 in Glasgow last year.

Dr. Oliver Geden, Senior Fellow of the  German Institute for International and Security Affairs (SWP) told journalists after the conference there had been no progress in the year since the Glasgow event. Since global emissions are still not dropping, it will be virtually impossible to avoid crossing the 1.5C line.

One of the key promises of the Paris Agreement was for a “global stocktake” every five years to close the gap between national pledges and global goals.  The gap will not be closed in the foreseseeable future, says Geden.  The gap is already huge and global emissions would have to drop by 25 percent by 2030 to keep under 2C, 45 percent to keep under 1.5C.

In Glasgow in 2020, the participating countries reluctantly agreed to reduce the burning of coal. The Sharm el-Sheik declaration confirmed that, but went no further. In fact, the latest figures from the IAE show that more coal was burned in 2022 than ever before.

Shamefully, the “Sharm el-Sheikh implementation plan” excluded any mention of winding down the use of fossil fuels.  As Professor Niklas Höhne, head of the Cologne-based New Climate Institute puts it, the 1.5 limit is “still in intensive care with its condition deteriorating”. The last year was wasted:

 “In the shadow of the energy crisis, we failed to shift into emergency mode. There was not even agreement on the most obvious: that all fossil energies would have to be phased out, not just coal.”

Höhne is a major critic of support for a new gas infrastructure, which will make it much harder to halve global emissions by 2030 to keep to the 1.5C limit.

COP27 was dominated by resistance from several key players seeking to defend their own interests at the cost of global climate action. China is determined to hold onto its membership of the G77 group of developing and emerging countries, to avoid paying into international “pots”, and stay, instead amongst the recipients of any funding available. The EU and USA want China, whose per capita emissions are already higher than those of the EU, to lose its status as a developing nation.

The big oil and gas producing economies lobbied to stop a recommendation to end coal burning and a joint declaration for a shift away from oil and gas.

Meanwhile Brazil, still controlled by the Bolsonaro administration, blocked moves to agree rules on landscape and biodiversity protection.

“In spite of the increasingly visible effects of climate change, too many countries are still unwilling to accept their responsibility for a rapid reduction of greenhouse gas emissions, “Professor Manfred Fischedick, President of the renowned Wuppertal Institute told the Science Media Centre.

Yet especially with regard to the most vulnerable countries – and to slow the increase in the number and intensity of extreme weather situations here at home – every tenth of a degree less of warming counts, says Fischedick.

Already out of reach? Protesters in Bonn call for 1.5°C limit

Any good news?

I find it difficult to be optimistic under the present circumstances. Here in Germany, with the Green Party in the coalition government, the energy crisis caused by the Russian war on Ukraine has resulted in major investment in the gas infrastructure. It is to be hoped the revival of fossil fuels we are seeing now will be short-lived. But how much damage will it do before renewables are in place to supply the world’s energy needs?

The International Energy Agency (IEA) has a more positive take on developments in its recently published annual report on renewable energy. It says the global energy crisis is “pushing the accelerator on renewable energy expansion”, particularly in the EU, US, China and India. It concludes that utility-scale solar and onshore wind power are now the cheapest options for new generation in “a significant majority of countries worldwide”.

In what it calls its “largest ever upward revision” for the sector, the Paris-based organisation raised its global forecast for renewables growth by nearly 30% compared with last year. This amounts to a 76% boost since 2020, Carbon Brief analysis finds.

The IEA now expects renewables to surpass coal as the world’s largest source of electricity generation by “early 2025”, reaching 38% of the power mix by 2027. The installed capacity of solar power alone is set to overtake that of coal in 2027.

But, despite all this, the IEA says countries are still not on track to achieve a net-zero emissions energy system by 2050.

The latest estimate from Climate Action Tracker shows that only Gambia is in line with the 1.5C limit. No major emitter fits the bill.

It is not that there is no good news on the climate front.

The EU has agreed to impose a carbon dioxide emissions tariff on imports of polluting goods such as steel and cement. This is the world’s first scheme of its kind, designed to support European industries as they decarbonise. It will also include fertilisers, aluminium and electricity.

 We can still avert climate catastrophe

We do have the wherewithal to abandon fossil fuels and decarbonise our societies:

The global biodiversity COP15 ended in Montreal with a ground-breaking agreement to protect 30 percent of the planet. It is far from perfect and leaves many environment groups dissatisfied. What worries me too, though, is that people are talking about it as a “Paris Agreement” for biodiversity. Sure, the Paris Agreement was a major breakthrough, but the best of treaties is worthless if they are not implemented. And looking at the state of the climate today …

We have to radically change our lifestyles and economies in the interests of the climate and biodiversity – which are, of course, intrinsically linked.

In a study published in Nature on December 12th, Jason Hickel, Giorgos Kallis, Diana Urge-Vorsatz, Julia Steinberger and their fellow authors argue the case for degrowth.

 “Reports this year by the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) suggest that degrowth policies should be considered in the fight against climate breakdown and biodiversity loss, respectively”, they write. The measures they discuss include “scaling down destructive sectors such as fossil fuels, mass-produced meat and dairy, fast fashion, advertising, cars and aviation, including private jets. At the same time, there is a need to end the planned obsolescence of products, lengthen their lifespans and reduce the purchasing power of the rich.”

The degrowth strategy would also include improving public services, introducing a green jobs guarantee, reducing working time and enabling sustainable development.

 “In our view”, the authors conclude, the question is no longer whether growth will run into limits, but rather how we can enable societies to prosper without growth, to ensure a just and ecological future.”

Zeke Hausfather, the climate scientist and energy systems analyst I quoted earlier, told Foresight in an interview:

“The future doesn’t boil down to either a 1.5 degree Celsius future or an apocalyptic hellscape. Climate change is ultimately a matter of degrees rather than thresholds […] The single most important thing we can do is to take as rapid action as possible to reduce emissions.”  For that, people have to become pro-active in tackling the climate problem:

“We should take more time to discuss how people can get involved in the solutions. And I don’t just mean buying electric cars or alternative diets. I’m talking about voting, organizing politically, reaching out to decision-makers and getting out on the streets. This aspect is absent in a lot of public discussions which tend to focus on the global impacts of climate change. We need people to mobilize and become politically active.“

Messedam: Last Generation activists block a road (Photo: Last Generation)

Here in Germany, the “Last Generation” group of climate activists has attracted widespread public attention with protests involving glueing themselves to roads and airport runways. The group aims to fight climate change and move the government to take stronger action  by generating public outrage through civil disobedience. They are facing a lot of criticism – and tough legal action, including imprisonment. But ultimately, as the movement sees itself, this is the “last generation” with the ability to halt the climate crisis and “correct our past mistakes”.  

“We have an obligation to act now, not only for ourselves but for all the generations to come”, says the mission statement.

Not everybody is willing to glue themselves to something or risk imprisonment for the sake of the planet and future generations. But we all have to take action in our own ways – now.

I’ll let the Last Generation have the last word:

“After all, when we come together, we are a formidable force. Don’t forget, it’s our action, our planet, and our legacy on the line.”

    The rise in temperature,sea level,ice melt, permafrost loss, CO2 levels methane levels and the subsequent loss of the methal hydrate is part of a natural cycle that usually takes 100,000 years. With our contribution it will take less than half that time, with elevated levels that will not stabilize for millions of years.
