The latest Met Office State of the Climate UK publication shows that the 21st century so far has been warmer overall than any period of equivalent length in the previous three centuries and that, despite some fluctuations, all seasons are warmer than at any time since records began in 1659 (Figure 1).
Growing degree days
The Met Office calculates "growing degree days", a weather-based measurement used to estimate the growth and development of plants and insects during the growing season (see Glossary). According to the latest State of the Climate UK, growing degree days have increased in all parts of the UK (Figure 2). The last 10 years have seen 2% more growing degree days per year on average compared with the most recent 30-year average (1991 to 2020), and 17% more when compared with the previous 30-year average (1961 to 1990).
The Met Office report that 2022 so far has been both warmer and drier than average. Seasonal assessments of autumn (September and October 2022), summer (June to August 2022), spring (March to May 2022) and winter (December 2021 to February 2022) show the following differences compared with the 1991 to 2020 seasonal averages for UK temperature and rainfall:
autumn (so far) (PDF, 587KB) was 0.5 degrees Celsius above average with 11% more rainfall
summer (PDF, 563KB) was 1.1 degrees Celsius above average with 38% less rainfall
spring (PDF, 594KB) was 0.8 degrees Celsius above average with 24% less rainfall
winter (PDF, 602KB) was 1.1 degrees Celsius above average with 7% less rainfall
More than 400 million tonnes of carbon dioxide (CO2) equivalent greenhouse gases (GHG) were emitted into the atmosphere in the UK in 2020.
The latest Department for Business, Energy and Industrial Strategy (BEIS) Greenhouse Gas Inventory shows that agriculture accounted for 11% of total UK net GHG emissions, on a territorial basis, while land use, land use change and forestry (subsequently called land use) accounted for a further 1%.
By 2020, total net GHG emissions had dropped by around 50% since 1990, the baseline year for emissions as agreed under the Kyoto Protocol, precursor to the Paris Agreement. Agricultural emissions fell by 16% and land use emissions by 70% over the same period (Figure 3).
The most recent BEIS statistics on each UK country's GHG emissions showed that England accounted for 59% of UK net GHG emissions (on a territorial basis) from land use and agricultural sources, while Scotland accounted for 19%, Northern Ireland for 16% and Wales for 10% in 2020 (totals add up to over 100% because of unallocated net reductions from harvested wood products).
There is considerable variation across the UK, with differences in climate, urban extent, topography and soil type. For example, land considered more difficult to farm because of climate and soil conditions is classed as a less favoured area (LFA) and predominantly used for sheep and beef cattle grazing. LFAs accounted for 86% of farmed land in Scotland (Arable farmer-led group: climate change evidence, 2021), 80% in Wales (Agriculture in Wales, 2019 (PDF, 1.93MB)), 69% in Northern Ireland (Statistical review of Northern Ireland agriculture, 2021) and 17% in England (Numbers of commercial holdings and key land areas and livestock types by less favoured areas at June each year: England (ODS, 332KB)).
Combined (agriculture and land use) net emissions were highest for Scotland, but adjusting for population size and area Northern Ireland was highest. London had lowest net emissions from these sources (Figure 4).

Total net emissions, net emissions per head, and net emissions per square kilometre, 2020
Data on emissions per head and per square kilometre have been calculated using population and area statistics included in the original dataset
Land use, land-use change and forestry (LULUCF) includes emissions and removals of CO2 from changes in the carbon stock in forestland, cropland, grassland, wetlands, settlements and harvested wood products, and of other greenhouse gases from drainage (excluding croplands and intensive grasslands) and rewetting of soils, nitrogen mineralisation associated with loss and gain of soil organic matter, and fires. Because the impact of biomass harvest on carbon stocks in ecosystems is included in this sector, any emissions of CO2 from burning biomass (regardless of the country of origin) are excluded from other sectors to avoid double counting them.
Agriculture includes emissions of greenhouse gases from livestock, agricultural soils (excluding carbon stock changes which are included in the LULUCF sector) and agricultural machinery.

Land cover and habitat extent
A 2021 Natural England carbon emissions and habitat review showed that habitats' capacity to sequester and emit carbon varies.
BEIS provide emissions for seven separate land use, land use change and forestry categories. In 2020, forest land and harvested wood products were overall carbon sinks, removing more carbon from the atmosphere than was emitted (Figure 5).
Across the UK, grassland was the only land use type that was both a net emitter (for example, Scotland and North East England) and a net remover (for example, Northern Ireland and West Midlands).
As the largest net remover of carbon, woodland is an important habitat for sequestering carbon dioxide. Forest Research estimates that the UK had around 3.24 million hectares of woodland in March 2022, accounting for 13% of the UK: 19% of Scotland, 15% of Wales, 10% of England and 9% of Northern Ireland.
UK woodland has increased by 8% over the last 20 years, and in all four nations: by 50% in Northern Ireland, 11% in Scotland, 5% in England and 3% in Wales. Rates of woodland planting have decreased since the 1970s despite recent fluctuations (Figure 6). Scotland accounted for 76% of total new UK woodland planted in 2022.
Habitat and soil conditions affect emission and sequestration rates. For example, peatlands, when pristine, act as the largest carbon store of any habitat and can sequester carbon indefinitely, but when in poor condition act as significant sources of carbon emissions.
Three habitat types provide the greatest potential store and sequestration of carbon in the UK: mountains, moorland and heathland (comprising peatland soils within blanket bog, raised bog and fens); woodland (including trees and scrub); and coastal margins (including marine and coastal habitats such as saltmarsh). These habitats accounted for a combined 27% of Great Britain in 2021, according to the latest data on land cover from the Centre for Ecology and Hydrology (CEH). This represents a 1% increase since 1990 despite a 22% loss in mountains, moorland and heathland (Figure 7).

Renewable energy sources accounted for 39% of total electricity generated in Quarter 2 (Apr to June) 2022. This is up from 6% in 2010 (Figure 8).
The Department for Business, Energy and Industrial Strategy (BEIS) also provide quarterly UK renewables trends statistics for electricity generated from renewable sources, including onshore and offshore wind, wave and tidal, solar, hydro, and bioenergy and waste. The share of energy from renewable sources in Quarter 1 (Jan to Mar) 2022 was 45%; since the first statistics in 2010, this is the second-highest share (highest was Quarter 1 2020).
According to the latest Department for Environment, Food and Rural Affairs (Defra) farm practices survey for England (26 May 2022), nearly two-thirds (64%) of farmers consider greenhouse gas (GHG) emissions to be "fairly or very important" when making decisions about their land, crops and livestock. The majority (58%) of respondents have taken action to reduce emissions from their land, with 82% recycling waste materials, 78% improving energy efficiency and 63% improving nitrogen fertiliser application accuracy. Comparable surveys are not available for UK nations.
The latest estimates from the ONS's Opinions and Lifestyle Survey (26 October to 6 November 2022) show that around two-thirds of adults were worried (very or somewhat) about the environment (62%) or climate change (64%). This appeared to be highest among adults aged 70 years and over compared with other age groups for both the environment (71%) and climate change (73%).
When asked about the way people use the environment, 85% of adults thought this had an impact (high or moderate) on climate change. Around 6 in 10 (61%) adults reported reducing the amount of waste they use, making this the most common action taken to tackle climate change over the last 12 months (Figure 9).
More men than women reported taking no action to help tackle climate change - around one-fifth of men (21%) reported taking no action compared with around in 1 in 10 (13%) women.
Of adults who reported making no changes, the most common reason why was feeling that their changes would have no effect, with around 4 in 10 (41%) of adults who made no changes reporting this.

Warming temperatures mean timings for spring and summer life cycle events have advanced significantly. The British Trust for Ornithology's Bird Trends report identifies 38 species in Great Britain that are showing clear signs of early breeding adapting to the earlier arrival of spring. This accounts for around a third (31%) of all species surveyed that are laying, on average, between three and 21 days earlier than in the mid 1960s.
The UK Research and Innovation (UKRI)-funded Living With Environmental Change (LWEC) research partnership, in its Climate change impact on biodiversity report cards, presents strong evidence that climate change is also an important factor determining the geographical distribution of species.
There has been a big increase in the number of invasive non-native species, such as the grey squirrel, signal crayfish and Japanese knotweed) in Great Britain's freshwater, marine and terrestrial environments between 1960 and 2020, according to the Joint Nature Conservation Committee (JNCC) Invasive Species Indicator. Over 3,248 non-native species were registered in Great Britain in 2020 and around 9% of these (303 species) were having a negative ecological or human impact, according to the 2020 non-native species report card (PDF, 638KB) from the Non-native Species Secretariat (NNSS).
In contrast, between 1980 and 2017, pollinators (377 species including bees and hoverflies) had declined by 30% in their distribution across the UK. Hoverflies showed a 41% reduction over the same period, but wild bees showed less of a decline (9% by 2019), according to the JNCC's pollinator insects indicator (Figure 10).
Rising sea levels are associated with the loss of coastal habitats (including saltmarsh), which are important for storing and sequestering carbon as well as providing sea defences and as habitats for a range of wildlife.
The Met Office outlines three causes of sea-level rise because of greenhouse gas emissions and subsequent global warming: expansion of the ocean as it warms; addition of water from loss of land-based ice (including glaciers and ice sheets); and changes in land water storage.
The latest State of the Climate UK 2021 shows that sea levels around the UK have risen by approximately 16.5 centimetres over the last 100 years or so, excluding the effects of natural vertical land movement.
Sea-level rise is predicted to increase with higher emissions scenarios. In the event of a 2-degree warming scenario, sea levels around the UK are projected to rise by approximately 11 centimetres per year by 2030, 19 centimetres by 2050 and 36 centimetres by 2100, according to UK climate projections from the Met Office (via their geospatial Climate Data Portal).
The UK's more southerly, easterly and far north coasts are likely to experience more extreme sea-level changes. UK tide gauge records already show substantial year-to-year changes in sea levels with notable differences depending on location around the UK. Parts of England are likely to experience the greatest sea-level rises, with an average rise of 22 centimetres by 2050, compared with an average of 14 centimetres in Northern Ireland, 17 centimetres in Scotland and 20 centimetres in Wales.
Green and blue infrastructure
Increasing the extent of green and blue space in urban areas is important to adapt to rising temperatures associated with climate change, as these spaces can help cool urban environments.
The ONS's natural capital accounts estimate the total annual value of the cooling benefit from green and blue space in UK urban environments to be £433 million in 2020, mostly because of cost savings from air conditioning and improved labour productivity. The total asset value for urban cooling has been increasing since estimates began in 2016 and reached £26,795 million in 2020 (Figure 11).
Sustainable and efficient abstraction and use of water can alleviate the growing pressure on water resources from the changing climate and weather patterns in the UK. In England, 85% of surface- and 73% of ground-water bodies achieved sustainable abstraction criteria in 2019. Comparable data are not available from elsewhere in the UK.
Reducing the amount of water that we consume and waste in the household could significantly improve water availability for people and the environment. Water usage in England and Wales is lower, on average, in households with a water meter (134 litres per person per day), compared with those without (174 litres), according to Water UK.
All UK nations also show reductions in water leakage and, compared with the earliest year data are available for each of the four countries, by 2021 to 2022, total leakage per day had reduced by:
58% in Scotland since 2006 to 2007
10% in Wales since 2016 to 2017
9% (by 2020 to 2021) in England since 2002 to 2003

Indicators from the Opinions and Lifestyle Survey (OPN) about people in Great Britain's worries about, attitudes towards and actions taken regarding the environment and climate change.
Adaptation is actions to adjust to climate change, and the extreme weather that it makes increasingly likely. This includes making homes more resilient to extreme heat and cold weather and adapting our landscapes to better cope with flooding or drought events, for example.
The seven greenhouse gases included in the atmospheric emissions accounts are those covered by the Kyoto Protocol:
carbon dioxide (CO2)
nitrous oxide (N2O)
sulphur hexafluoride (SF6)
nitrogen trifluoride (NF3)
These gases contribute to global warming and climate change. The potential of each gas to cause global warming is assessed in relation to a given weight of CO2, so greenhouse gas emissions are measured as carbon dioxide equivalent (CO2e).
A degree day is an integration of temperature over time and is commonly used to relate temperatures to particular impacts. The Met Office calculate heating, cooling and growing degree days for relating temperature to the requirement for heating or cooling of buildings to maintain comfortable temperatures or the conditions suitable for plant growth respectively.
Global warming potential
Global warming potential (GWP) is measured in terms of carbon dioxide equivalents (kilogrammes CO2e), which takes account of the relative impact of the different gases involved.
Growing degree days
The day-by-day sum of the mean number of degrees by which the air temperature is more than a value of 5.5 degrees Celsius, the temperature deemed as providing suitable conditions for plant growth.
The Kyoto Protocol was adopted on 11 December 1997. Because of a complex ratification process, it entered into force on 16 February 2005. Currently, there are 192 Parties to the Kyoto Protocol. In short, the Kyoto Protocol operationalised the United Nations Framework Convention on Climate Change by committing industrialised countries and economies in transition to limit and reduce greenhouse gases emissions in accordance with agreed individual targets. The Convention itself only asks those countries to adopt policies and measures on mitigation and to report periodically.
Mitigation is the reduction of emissions of greenhouse gases which lead to global warming. This includes reducing energy consumption and changing to low emission energy sources.
Natural vertical land movement
This includes all processes that impact upon the elevation at given locations, from tectonic movements, subsidence, ground water extraction and glacial adjustments, causing land to move up or down.
Net zero is the UK government's target for at least a 100% reduction of net greenhouse gas emissions (compared with 1990 levels) in the UK by 2050. This can be achieved by a combination of emission reduction and emission removal.
Species that have reached Great Britain by accidental human transport, deliberate human introduction, or which arrived by natural dispersal from a non-native population in Europe.
Species that transfer pollen from one flower to another to fertilise plants so that they can reproduce, such as bees, birds, butterflies and moths.
