This is the best summary I could come up with:

In 2016, influenced by a strong El Niño event - a natural climate shift that tends to increase global temperatures - the world saw around 75 days that went above that mark.

One theory - which is still uncertain - is that a fall in air pollution from shipping across the North Atlantic has reduced the number of small particles and increased warming.

Up until now, these "aerosols" had been partly offsetting the effect of greenhouse gas emissions by reflecting some of the sun's energy and keeping the Earth's surface cooler than it would have been otherwise.

While the northern hemisphere will naturally cool in autumn and winter, there is a view that the large temperature differences from the pre-industrial period may persist, especially as El Niño reaches a peak at the end of this year or early next.

Researchers believe that these ongoing high temperature anomalies should be a wake-up call for political leaders, who will gather in Dubai in November for the COP28 climate summit.

In March, the UN urged countries to accelerate climate action, stressing effective options to reduce emissions were available now, from renewables to electric vehicles.
