on the global climate system. CO2 concentrations in the Keeling Curve record first reached 348 ppm, 25% above pre-industrial levels, in 1986.  Professor Betts added: “The human-caused build-up of CO2 in the atmosphere is accelerating. It took over 200 years for levels to increase by 25%, but now just over 30

levels then decline over the rest of the century in that scenario. The human emissions driving this fall rapidly, reaching net zero mid-century and becoming negative after that.   Although the long-term rise in CO2 concentrations comes from human-induced activities, nature also has an influence

Deploying on 80 operational tours, Squadron Leader Horn MBE has provided critical meteorological services around the world in support of UK Defence operations and exercises. After first joining the Met Office in 1975 as an Assistant Scientific Officer, observing the weather and compiling climate

Environmental Policy Introduction The Met Office is a world leading provider of weather, climate and environmental information to the public, government and business. This helps us to stay safe, thrive and take better decisions about the environment. Equally, as a force for good, we take our own

these. Background Land cover (the physical characteristics of the land surface, including natural, agricultural and urban environments), and the activities taking place on the land, can influence public health in a wide variety of ways. These include: i) direct effects, such as allergic rhinitis related

Kendon said: “The record-breaking sunshine across the UK this year was driven by the frequent influence of high pressure that reduced cloud cover and brought sunny skies for many.   “Spring was exceptional, and many will remember the long spells of days with largely unbroken sunshine. It began

The latest State of Wildfire report is building unequivocal evidence of how climate change is increasing the frequency and severity of extreme wildfires.

Human-driven climate change made wildfires in parts of South America and Southern California many times larger and more destructive, according to an annual assessment by international experts.  According to climate models, the Los Angeles wildfires in January were twice as likely and 25 times

The latest edition in an annual series of global climate reports shows that Europe experienced its warmest year in 2020 by a considerable amount.

relatively cooler, 2020 also saw the UK reach its third highest annual average temperature, after 2014 and 2006. The 31st State of the Climate report – published online by the American Meteorological Society and covering 2020 - also showed that the average surface temperature over land areas

and climate processes that influence long-term drought conditions in the UK can be accounted for by looking at both the global general circulation model and high-resolution regional climate model projections in UKCP18.
