What climate change may be inferred from the warmest September ever
In 2023, September will break records for temperature along with a few other months. What is anticipated in the upcoming months, and why has this year been so warm?
September has proven to be the hottest September ever, by a wide margin, continuing the trend of this year in which nearly every month has set a temperature record. Even though the year still has three months left, it is becoming more likely that 2023 will surpass 2016’s record for warmth to become the warmest year ever.
The remarkable run of temperature records that have occurred this year is not surprising. Despite the unpredictable nature of individual events, scientists had anticipated an extremely warm year due to the formation of El Nino in the Pacific Ocean. It is also predicted that the final three months of the year will be warmer than typical.

Following a number of previous milestones for other months this year, September broke records for temperatures. This year’s July was really the warmest of the year, if not the warmest month overall. Thus, July of this year is the highest monthly average worldwide temperature ever recorded. That month had a few days when the daily temperature records were broken.
June was the warmest June ever before then, while the average temperatures for February, March, April, and May were all among the top five highest ever for the corresponding months.
Furthermore, the three months from June to August were the warmest on record, with global average temperatures reaching levels that were at least two times more likely due to climate change, not only globally.
September made another questionable difference, even in this dire situation. September’s average global temperature was 1.75 degrees Celsius higher than the pre-industrial era’s average (1850–1900), which is typically used as a reference point to measure temperature variations. This year, not even July deviated as much from the pre-industrial average as any other month did.
Even by comparison with a more recent baseline, September was very warm; it was 0.93 degrees Celsius hotter than the norm for the years 1991 to 2020.
“Unprecedented heat waves have been hitting land and water worldwide since June. Larger beyond anything we have ever observed in the past, the temperature anomalies are. For the time of year, the Antarctic winter sea ice extent was at its lowest ever. The World Meteorological Organization Secretary-General, Petteri Taalas, stated, “What is particularly concerning is that the warming El Niño event is still developing, so we can expect these record-breaking temperatures to continue for months, with cascading impacts on our environment and society.”
Because the average temperature of the first nine months of 2023 is already greater than that of the equivalent period of 2016, the warmest year on record to date, scientists believe that 2023 will turn out to be the warmest year ever. 2016 saw an average temperature 1.28 degrees Celsius higher than pre-industrial levels. It is also feared that 2023 may be the first year that the temperature rises above 1.5 degrees Celsius.
A statement from the European Commission-run Copernicus Climate Change service stated that the average global temperature for the first nine months of 2023 (January–September) is 0.05°C higher than the nine-month average for 2016, which is currently the warmest calendar year on record, and 0.52°C higher than the corresponding 1991–2020 average.
Nothing urgent to take care of:
The scientific world has been quite interested in this year’s string of record-breaking temperature events, and they have consistently noted that this is absolutely abnormal—even when considered in the context of recent years of continuously rising temperatures. Numerous heatwaves this year—including one that occurred in the improbable month of April—have been linked by scientists to climate change.
However, this hasn’t led to any country-wide policy reaction in the form of more robust climate action.
Undoubtedly, there isn’t much that humans can do to lower the temperature in the upcoming month or year. In the short term, there is no climate action that can stop the temperature from rising or stop similar warming events from happening again. Any significant deviance from the existing trend over a brief period of time would require a large global disruption such to the one brought on by the Covid epidemic.
However, the planet’s strategy to combat climate change has not been made any more urgent by the exceptional warming events of this year. According to an assessment by the World Meteorological Organization, there is a high likelihood that the world will surpass the 1.5 degree Celsius threshold within the next four years, if not this year.
The commitment to increase the installed capacity of renewable energy by 2030 represents the sole tangible outcome of this year’s climate talks. One of the conclusions from the G20 summit held in New Delhi last month was this. According to the International Energy Agency, by 2030, carbon dioxide emissions might be avoided by 7 billion tonnes thanks to just one action. But even if this were accomplished, it would not be enough. Based on present trends, projections indicate that by 2030, greenhouse gas emissions will surpass the 1.5 degree Celsius acceptable threshold by a minimum of 24 billion tonnes.
At this year’s annual climate change meeting, which is set to take place in Dubai, nations are expected to conduct an inventory of global climate action and evaluate its effectiveness in relation to the 1.5 and 2 degree Celsius temperature targets. It is anticipated that the significant gaps that the stock-taking exercise would likely disclose will motivate nations to adopt more aggressive climate action.
