Smoke from US wildfires has reached Europe, satellite images reveal

According to scientists from the European Union's Copernicus Atmosphere Monitoring Service, smoke from the wildfires in the western United States has travelled 8,000 kilometres and reached Britain and other parts of northern Europe.

Mark Parrington, a senior scientist at the Copernicus Service has stated that "the scale and magnitude of these fires are at a level much higher than in any of the 18 years that our monitoring data covers, since 2003".
