July 21 Was Earth’s Hottest Day on Record

As of June 2024, the past 13 months have all been the hottest on record.

People cool off at a fountain in the Madrid Río Park amid heat wave conditions in Madrid on July 23, 2024. The Copernicus Climate Change Service (C3S) said the global average surface air temperature on July 21 was 17.09 degrees Celsius, a fraction above the previous record set in 2023.

July 21 was Earth’s hottest day on record, overtaking the record set last July during the hottest year in millennia.

The European Copernicus Climate Change Service (C3S) found that Sunday’s average air surface temperature soared to 17.09°C , or 62.76°F, according to preliminary data. While that is only 0.1°C warmer than the previous record — set on July 6, 2023 — it was nearly 3°C higher than the pre-2023 record, set at 16.8°C on August 13, 2016.

“What is truly staggering is how large the difference is between the temperature of the last 13 months and the previous temperature records,” C3S Director Carlo Buontempo said in a statement. “We are now in truly uncharted territory and as the climate keeps warming, we are bound to see new records being broken in future months and years.”

The news follows a year of shattered temperature records as El Niño combined with the climate emergency to heat air and ocean to levels well above average. While El Niño conditions ended in April, scientists still predict that 2024 could overtake 2023 as the hottest year on record.

As of June 2024, the past 13 months have all been the hottest of their kind on record. June 2024 was also the 12th month in a row to see its average temperature meet or surpass 1.5°C above preindustrial levels — the most ambitious temperature goal enshrined in the Paris agreement.

Scientists have warned that the only way to keep global temperatures from rising further is to rapidly phase out the use of oil, gas, and coal and transition to renewable energy.

Before Sunday, the last hottest day on record was July 6, 2023, which was also the fourth consecutive day to break that record. The previous record was set at 17.08°C, or 62.74°F, according to Copernicus. However, since the 2016 temperature record was first broken on July 3, 2023, 57 days in the past year have also surpassed it.

What’s more, C3S found that the last 10 years have been the 10 years on record with the highest average daily temperatures.

“The difference in the highest daily average temperature between the lowest ranked of those 10 years (2015) and the previous record before 2023 (13 August 2016) was 0.2°C. The jump from the 2016 record to 2023/2024 is about 0.3°C, highlighting how substantial the warmth of 2023 and 2024,” C3S said.

Record-breaking temperatures have also brought extreme weather.

On Sunday, Florida meteorologist Jeff Berardelli wrote on social media that “the most anomalously warm places were Antarctica and Western Canada where several hundred wildfires blaze, many out of control.”

C3S also said that Sunday’s record was in part driven by “much-above-average temperatures over large parts of Antarctica.”

The warmest day on record also coincided with heatwaves in Russia, Europe, and the U.S., Reuters reported.

C3S predicted that temperatures would continue to rise in the short term.

“In the coming days, we are expecting the daily global average temperature to further increase and peak around 22 or 23 July 2024 and then go down, but with possible further fluctuations in the coming weeks,” the agency said.

In the longer term, temperature trends will depend on whether policymakers can take ambitious action to reduce greenhouse gas emissions and halt the destruction of natural carbon sinks.

Truthout Is Preparing to Meet Trump’s Agenda With Resistance at Every Turn

Dear Truthout Community,

If you feel rage, despondency, confusion and deep fear today, you are not alone. We’re feeling it too. We are heartsick. Facing down Trump’s fascist agenda, we are desperately worried about the most vulnerable people among us, including our loved ones and everyone in the Truthout community, and our minds are racing a million miles a minute to try to map out all that needs to be done.

We must give ourselves space to grieve and feel our fear, feel our rage, and keep in the forefront of our mind the stark truth that millions of real human lives are on the line. And simultaneously, we’ve got to get to work, take stock of our resources, and prepare to throw ourselves full force into the movement.

Journalism is a linchpin of that movement. Even as we are reeling, we’re summoning up all the energy we can to face down what’s coming, because we know that one of the sharpest weapons against fascism is publishing the truth.

There are many terrifying planks to the Trump agenda, and we plan to devote ourselves to reporting thoroughly on each one and, crucially, covering the movements resisting them. We also recognize that Trump is a dire threat to journalism itself, and that we must take this seriously from the outset.

After the election, the four of us sat down to have some hard but necessary conversations about Truthout under a Trump presidency. How would we defend our publication from an avalanche of far right lawsuits that seek to bankrupt us? How would we keep our reporters safe if they need to cover outbreaks of political violence, or if they are targeted by authorities? How will we urgently produce the practical analysis, tools and movement coverage that you need right now — breaking through our normal routines to meet a terrifying moment in ways that best serve you?

It will be a tough, scary four years to produce social justice-driven journalism. We need to deliver news, strategy, liberatory ideas, tools and movement-sparking solutions with a force that we never have had to before. And at the same time, we desperately need to protect our ability to do so.

We know this is such a painful moment and donations may understandably be the last thing on your mind. But we must ask for your support, which is needed in a new and urgent way.

We promise we will kick into an even higher gear to give you truthful news that cuts against the disinformation and vitriol and hate and violence. We promise to publish analyses that will serve the needs of the movements we all rely on to survive the next four years, and even build for the future. We promise to be responsive, to recognize you as members of our community with a vital stake and voice in this work.

Please dig deep if you can, but a donation of any amount will be a truly meaningful and tangible action in this cataclysmic historical moment. We’re presently working to find 1500 new monthly donors to Truthout before the end of the year.

We’re with you. Let’s do all we can to move forward together.

With love, rage, and solidarity,

Maya, Negin, Saima, and Ziggy
