“How many more records does it take before we phase out fossil fuels and deal with it?” asked one climate campaigner.

European scientists officially confirmed Tuesday that 2023 was the hottest year on record, surpassing 2016 by a huge margin as greenhouse gas emissions from fossil fuels continue to drive global temperatures to terrifying new highs.

The conclusion from the European Union’s Copernicus Climate Change Service was hardly unexpected given the unparalleled heatwaves that gripped large swaths of the planet last year, ushering in what the head of the United Nations called “the era of global boiling.”

Last year’s global average temperature was 14.98°C, 0.17°C warmer than 2016, 0.60°C warmer than the 1991-2020 average, and 1.48°C warmer than the 1850-1900 pre-industrial level, according to Copernicus.

“2023 was an exceptional year with climate records tumbling like dominoes,” said Copernicus deputy director Samantha Burgess. “Not only is 2023 the warmest year on record, it is also the first year with all days over 1°C warmer than the pre-industrial period. Temperatures during 2023 likely exceed those of any period in at least the last 100,000 years.”

Liz Bentley, chief executive of the U.K.’s Royal Meteorological Society told CNN on Tuesday that after last year’s record-shattering summer, scientists predicted that global warming would reach around 1.3°C above pre-industrial levels.

That projection, Bentley said, has been “annihilated” by the new Copernicus data, which shows that planetary warming is perilously close to the Paris accord’s 1.5°C target.

“If you look at climate projections, when we expect to see temperature changes of close to 1.5°C, indeed it has come sooner than many would have expected,” Bentley added. “We’ve definitely seen an acceleration towards that, rather than it being a kind of linear progression. It feels like it’s rising much more exponentially.”

Scientists expect 2024 to be even hotter than last year, raising the stakes for badly lagging global efforts to rein in planet-warming fossil fuel production, which in 2023 hit record levels in the United States—the largest historical contributor to greenhouse gas emissions.

“How many more records does it take before we phase out fossil fuels and deal with it?” asked climate campaigner Mike Hudema.

Copernicus director Carlo Buontempo said in a statement Tuesday that “the extremes we have observed over the last few months provide a dramatic testimony of how far we now are from the climate in which our civilization developed.”

“This has profound consequences for the Paris Agreement and all human endeavors,” said Buontempo. “If we want to successfully manage our climate risk portfolio, we need to urgently decarbonize our economy whilst using climate data and knowledge to prepare for the future.”

‘Five-Alarm Fire’ as Global Temps Breach 2°C Threshold

While scientists were quick to point out that this was just a daily anomaly, not a permanent shift, it is a “canary in the coalmine” that “underscores the urgency of tackling greenhouse gas emissions.”

Global temperatures surpassed 2°C above preindustrial levels for the first time Friday, according to preliminary data from the European Union’s Copernicus Climate Change Service.

The European Centre for Medium-Range Weather Forecasts’ ERA5 data set showed global service air temperatures rising 2.07°C above the 1850-1900 average on Friday and 2.06°C above that average on Saturday, the service said.

“This is a five-alarm fire for humanity,” the group Climate Defiance tweeted in response to the figures.

In the 2015 Paris agreement, world leaders set out to keep warming to “well-below” 2°C above preindustrial levels. Allowing warming to breach that point increases several climate risks, according to the Intergovernmental Panel on Climate Change (IPCC): 2°C of warming compared with 1.5°C would raise sea levels by an additional 0.1 meters by 2100, destroy 99% of coral reefs instead of 70% to 90%, and expose several hundred million more people to poverty and climate-related hazards by 2050.

Friday’s 2°C breach was first noted by Copernicus Climate Change Service deputy director Samantha Burgess on social media Sunday. She said the day was also 1.17°C above the 1991-2020 average, making it the warmest November 17 on record.

Scientists were quick to point out that this doesn’t mean global heating has breached the 2°C threshold long-term.

“The 1.5°C and 2°C warming thresholds have been defined in terms of the trend line,” University of Pennsylvania climate scientist Michael Mann tweeted. “Not individual years, let alone months, weeks, or days (the shorter the time period, the larger the random fluctuations). Those who imply otherwise are misleading you.”

Richard Allan, professor of climate science at the University of Reading in the U.K., told CNN that it was “entirely expected that single days will surpass 2°C above preindustrial well before the actual 2°C target is breached over many years.”

“We are blowing past warning signs with wild abandon. We are approaching the precipice and flooring the gas.”

That said, the reading was a “canary in the coalmine” that “underscores the urgency of tackling greenhouse gas emissions,” Allan said.

It also comes in a year of dropping canaries: The 12 months from November 2022 to October 2023 were the 12 hottest on record, according to a Climate Central analysis. 2023 saw the hottest Northern Hemisphere summer on record, the hottest month in July, and is likely to be the hottest year not just since record-keeping began, but in the last 125,000 years. And it’s not just numbers. The record-breaking temperatures fueled deadly heatwaveswildfires, and floods around the world.

“The indicators are flashing red,” Climate Defiance wrote. “The planet’s vital signs are clear. Humanity is on life support. With the El Niño cycle just beginning, this 2°C breach sadly represents not a climax but a small taste of what is to come.”

“This is happening faster than expected,” the group continued. “We are blowing past warning signs with wild abandon. We are approaching the precipice and flooring the gas. This is madness. Utter madness.”

The 2°C breach comes a little less than two weeks from the start of the next United Nations Climate Change Conference in the United Arab Emirates. A recent report from U.N. Climate Change found that national plans were still incompatible with limiting warming to 1.5°C and that world leaders must take “bold strides forward” at the conference “to get on track.” More than 650 scientists have signed a letter to President Joe Biden urging him to back a fossil-fuel phaseout at the talks.

“It’s just one day (so far) above 2°C, but it highlights again that the world is approaching the limits set out by the Paris Agreement,” IPCC scientist Ed Hawkins tweeted. “We already have many of the solutions to rapidly reduce emissions and halt the rise in global temperatures. We just need to choose to use them.”

Science shows the severe climate consequences of new fossil fuel extraction

The world has just suffered through its warmest month ever recorded. Heatwaves have swept across southern Europe, the US and China, breaking many temperature records in the process.

Climate scientists have been sounding the alarm for decades that this type of event will become more frequent as the world continues to warm. The major culprit behind this is the burning of fossil fuels. So it’s extremely concerning that the UK government has announced its intention to grant hundreds of licences for new North Sea oil and gas extraction.

Although burning fossil fuels to generate power and heat has enabled society to develop and flourish, we are now experiencing the unintended side effects. The carbon dioxide that has been added to the atmosphere is leading to a rise in global temperatures, causing heatwaves to become hotter and downpours more intense. The resulting large-scale disruption and suffering is becoming ever more visible.

This warming will continue, with worsening climatic consequences, until we reduce global carbon dioxide emissions to “net zero”. After that, we will still have to live and suffer in a warmer climate for generations. The collective choices we make now will matter in the future.

The small-scale, but high-profile, disruptions caused by Just Stop Oil protesters in the UK are extremely frustrating for many. But their single demand – for no licenses for new UK coal, oil and gas projects – is consistent with the science underpinning the international agreements that the UK has signed.

Temperatures are rising

Since the 1860s, the scientific community has understood that adding more carbon dioxide to the atmosphere would warm the climate. And as long ago as 1938, the burning of fossil fuels was linked to the observed rise in both carbon dioxide levels and global temperatures. Fast forward to now and global temperatures are warmer, and increasing faster, than at any point in human civilisation.

In response to the overwhelming scientific evidence, the UK and 193 other nations came together in 2015 to ratify the Paris agreement on climate change. One of the agreed goals is to limit global warming to well below 2°C, and even aim for 1.5°C, compared to the pre-industrial era.

However, the latest synthesis report from the Intergovernmental Panel on Climate Change, which all governments explicitly endorsed, paints a stark reality. If we burn all of the fossil fuels that we currently have access to, then global warming will exceed 1.5°C and may reach 2°C.

To avoid breaching the limits set out by the Paris agreement, some of the coal, oil and gas that we can already extract must remain unburnt. New fossil fuel extraction projects will make it even harder to stop further global warming.

Build up renewable infrastructure

There are other options. The UK government’s official advisers, the Climate Change Committee, have put forward a vision for UK power generation consistent with a net zero future. They say that the UK could provide all of its energy needs by 2050 through a combination of renewables, bioenergy, nuclear, hydrogen, storage and demand management, with some carbon capture and storage for fossil gas-based generation in the meantime.

If the UK followed the example of China and rapidly increased its investments in renewable energy, then it could achieve energy security without causing additional global warming. China emits the most carbon dioxide of any country in the world. But it is installing more renewable energy generation than the rest of the world combined.

Rapidly reducing our reliance on fossil fuels, and not issuing new licenses to extract oil and gas, is the most effective way of minimising future climate-related disruptions. The sooner those with the power to shape our future recognise this, the better.

The “crazy” extreme weather rampaging around the globe in 2023 will become the norm within a decade without dramatic climate action, the world’s leading climate scientists have said.

The heatwaves, wildfires and floods experienced today were just the “tip of the iceberg” compared with even worse effects to come, they said, with limitations in climate models leaving the world “flying partially blind” into the future.

“We need to stop burning fossil fuels,” said Dr Friederike Otto at Imperial College London. “Now. Not some time when we’ve allowed companies to make all the money they possibly can.”

Prof Emily Shuckburgh at the University of Cambridge in the UK said: “Anyone in any way perpetuating the fossil fuel era is firmly on the wrong side of history.”

“Knowing that we will look back on today’s extreme events as mild relative to what lies in our future is truly mind-boggling,” said Prof Andrea Dutton at the University of Wisconsin-Madison, US. “The speed at which we make this transition will define the future that we get.”
