 Warmest September on record as global temperatures spike due to climate change

According to the EU climate service, September's global temperatures were the highest on record, far exceeding the previous peak.

Last month was 0.5C hotter than the previous record established in 2020 and 0.93C hotter than the average September temperature between 1991 and 2020.

The El Nio weather event and ongoing emissions of warming gases are thought to be the main causes of the current hot wave.

According to reports, 2023 is now "on track" to be the warmest year ever.

After the northern hemisphere's hottest summer on record, September's high milestone comes as soaring temperatures continue to rise.

The month's departure from the long-term normal was the largest in records going back to 1940, according to data from the Copernicus Climate Change Service.

Certain data details have stunned scientists quite a little.

As a climate scientist, I think this month was simply gobsmackingly bananas, Zeke Hausfather, an accomplished researcher, remarked on the platform once known as Twitter.

Even worse differences exist in some places of the world than beating a long-term recent norm by almost a degree. For instance, heating levels in Europe exceeded the long-term average by 2.51C, which was exceptional.

"The unprecedented heats for the time of year observed in September - preceding a record summer - have broken records by an unusual amount," stated Dr. Samantha Burgess, the assistant director of the Copernicus Climate Change Service (C3S).

How does El Nio impact the weather? What is it?

Four ways that extreme weather is deteriorated by climate change

The gap between present-day temperatures and those before the widespread usage of fossil fuels is one key indicator that climate researchers consider.

The greatest temperature for a single month ever recorded occurred last month, when temperatures were about 1.75C higher than they were during this so-called pre-industrial epoch.

Researchers will feel quite uneasy about this.

Political leaders gathered in Paris in 2015 and decided to work toward keeping the increase in global temperatures this century under 1.5C.

Since the Paris aim pertains to decades rather than months, September's number does not violate that commitment. However, it is unquestionably a troubling course of action.

However, Copernicus predicts that 2023 is "on track" to surpass all previous records for temperature rise. Scientists anticipate that this year as a whole will remain within that 1.5C limit. The year ending in September surpassed 2016 as the hottest year on record by 0.05C.

October has been marked by extreme heat that has broken numerous monthly high records, especially in Spain.

As the El Nio weather phenomena has not yet reached its apex, global temperatures could rise considerably higher than typical.

El Nio is a component of the El Nio Southern Oscillation, which is the primary natural mode of seasonal or annual fluctuation in Earth's climate. Warm water in the East Pacific rises to the surface during El Nio episodes, adding to the heat already present in the atmosphere.

When combined with the long-term warming brought on by humans, primarily through the burning of fossil fuels, which releases greenhouse gases that warm the earth, this is one of the causes of the rising global temperatures.

As policymakers get ready to assemble for the COP28 climate summit at the end of November, experts say the extent of the warming places increased pressure on them to take action.

The need for ambitious climate action has never been more urgent, according to Dr. Burgess, who noted that COP28 is only two months away.
