• Europe had its warmest summer on record this year, according to EU scientists.
  • The EU's Copernicus Climate Change Service said the average surface air temperature in June-August was close to 1.0C above the 1991-2020 average.
  • This makes it the hottest in its dataset, with the previous warmest summers, 2010 and 2018, 0.1C cooler.

Europe had its warmest summer on record this year, though only by a small margin over two previous highest temperatures for June-August, European Union scientists said on Tuesday.

The EU's Copernicus Climate Change Service said the average surface air temperature in June-August was close to 1.0C above the 1991-2020 average, making it the hottest in its dataset. The previous warmest summers, 2010 and 2018, were 0.1C cooler.

The 2021 summer temperature marks the latest milestone in a long-term global warming trend as emissions of greenhouse gases change the planet's climate.

Copernicus' records go back to 1950 but are cross-checked with other data sets that trace back to the mid-19th century.

It said in a statement that, globally, August 2021 was, together with August 2017, the third-warmest on record at a little over 0.3C warmer than the 1991-2020 average.

For Europe, August 2021 was near the 1991-2020 average, but with contrasting conditions across the continent. These included record-breaking maximum temperatures in Mediterranean countries, warmer-than-average temperatures in the east and generally below-average temperatures in the north.

Earlier on Tuesday, green groups called for the COP26 conference, which was put back from last year due to the COVID crisis and is scheduled to take place from Oct. 31 to Nov. 12 in Glasgow, to be delayed.

What’s the World Economic Forum doing about climate change?

Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.

To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.

The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.

This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

Typically delegates from more than 190 countries attend the annual talks, yet with many countries grappling with COVID-19 and poorer nations struggling to access vaccines, they should be postponed, the Climate Action Network (CAN) said. read more
