Scientists have warned that the planet should continue to warm below a critical barrier, which was reached in July.

Scientists have warned that the world should keep global warming below 1.5 degrees Celsius, but the planet has been creeping ever closer to that limit in recent years. Last month, the world received its first taste of what summer would be like at that level.

The European Union’s Copernicus Climate Change Service revealed on Tuesday that worldwide average temperatures in July, the hottest month on record, were roughly 1.5 degrees Celsius warmer than the pre-industrial era, which ended in the mid- to late- 1800s.

After devastating heat waves over multiple continents and astonishing record-breaking temperatures in the oceans, this news was made. According to the Copernicus satellite, this is the first summer month in which temperatures have risen above 1.5 degrees, a possible preview of future summers.

Scientists consider the 1.5-degree barrier to be a crucial tipping point for the world, beyond which the risks of excessive heat, flooding, drought, wildfires, and food and water shortages would increase.

It is the objective chosen by scientists in the historic Paris Agreement of 2015 to lessen the impact of the climate problem and buy time to transition away from fossil fuels that contribute to global warming.

Furthermore, it is not something that is recorded on a daily or monthly basis. The prospect of a long-term increase in global temperature of more than 1.5 degrees Celsius has scientists particularly worried. About 1.2 degrees of global warming had occurred by the year 2022.

In spite of the fact that “breaking the 1.5-degrees-Celsius threshold for a day, week, or month is not the same as breaking it for the long-term average,” Copernicus scientist Rebecca Emerton stressed the need of keeping track of how often and for how long we do so. The severity of the consequences will increase as global temperatures rise.

By a significant margin, July 2023 was the warmest month on record.

Global temperatures have risen by more than 1°C (1.8°F) over pre-industrial levels in 19 of the 30 hottest months on record, all of which have occurred in the last eight years. The average global temperature in July was 16.95 degrees Celsius (62.5 degrees Fahrenheit), which is approximately a third of a degree Celsius higher than the previous record set in July 2019.

Many people are unprepared for the catastrophic impacts of the climate catastrophe, which have been increasingly apparent over the past few years. Emerton warned that if global warming continues, the world will see considerably more severe weather than is currently being experienced by much of the earth.

Emerton said that even a fraction of a degree of warming is significant because of the effects that similar events have already had on people and the earth.

There have only been nine other months warmer than March 2023 by more than 1.5 degrees Celsius over the historical norm, according to Berkeley Earth, a nonprofit that collects and analyses environmental data. Previous months with temperatures 1.5 degrees warmer than pre-industrial times occurred in either winter or early spring.

For the first time in the history of the Northern Hemisphere summer, we have beyond the 1.5 degree Celsius threshold, according to Berkeley Earth’s Lead Scientist Robert Rohde, making this a crucial period for the planet.

Rohde, who was not involved in the Copernicus assessment, told that while the recent exceptionally warm winters were noteworthy, experiencing severe temperatures in July was likely to have bigger immediate impacts on people’s lives. By contrast, increasing the temperature by the same amount in the summer can lead to previously unheard-of extremes.

It’s improbable that the entire year of 2023 would be 1.5 degrees warmer than pre-industrial times, but Rohde has predicted that it will be the warmest year on record.

The average temperature for the year so far is below 1.5 degrees Celsius, and we don’t expect the rest of 2023 to be warm enough to raise that number.

Scientists from Copernicus warned that if El Nio keeps strengthening, the world could see more of these temperature records broken.

There will be more days, weeks, months, and years with record-breaking temperatures, as well as other repercussions on our Earth system, Emerton predicted, even if the climate catastrophe does not worsen. To prevent further warming, it is imperative that we cut down on emissions as much as possible.
