Climate change in Scotland

Climate change in Scotland is already causing a range of impacts on Scotland. 2022 was Scotland's warmest year on record with the temperature reaching 35°C in the Scottish Borders in July.

Climate change has already changed timings of spring events such as leaf unfolding, bird migration and egg-laying. Severe effects are likely to occur on biodiversity.

The mitigation of climate change and adaptation is a matter for the devolved Scottish Parliament.

Greenhouse gas emissions

Scotland's greenhouse gas emissions only accounted for 10% of the UK's emissionshttp://www.scotland.gov.uk/Resource/Doc/283799/0086005.pdf GHG Emissions by sector in 2003, when figures were published. 37% of Scottish emissions are in energy supply and 17% in transport. Between 1990 and 2007, Scottish net emissions have reduced by 18.7%.http://www.scotland.gov.uk/Topics/Environment/climatechange/what-is/research-science Scottish Government- Climate Change The industrial processes sector had the largest decrease, of 72% with a reduction of 48% in the public sector trailing closely behind.

Impacts on the natural environment

Temperature and weather changes In Scotland, the effects of climate change can be seen in raised temperature changes, increased rainfall and less snow cover. These changes have a significant impact on the growing, breeding and migration seasons, as well as species abundance and diversity.

Ecosystems Past observations have indicated some of the likely effects of climate change on biodiversity. Climate change has already changed timings of spring events such as leaf unfolding, bird migration and egg-laying. The population of species could change due to the speed at which they adapt.

Changes in the ranges of plant and animal species have been observed. New species may move to Scotland with the changing climate. Shifts may occur on hillsides and species that are already confined to high mountains may become extinct in Scotland.

Severe effects are likely to occur on biodiversity. Species of plants and animals that can't adapt quickly enough may become extinct or be replaced by other creatures. Coastal habitats, including machairs, may disappear due to high sea levels eroding the land. Salmon spawning beds may be wiped out by flash floods causing population problems for the species. There will be new risks to animals, plants and their habitats, including non-native pests and diseases.Scotland's Climate Change Adaption Framework – Biodiversity and Ecosystem Resilience, Scottish Government. [Accessed 1 May 2010]

When all these effects are combined with human response, such as land use change and the growth of new forests, Scotland's ecosystems could change drastically.

Impacts on people

Health

The United Kingdom, along with Scotland, has experienced a significant increase in severe heat waves. Increasingly intense and prolonged heat periods can have dire health consequences. Extreme heat has already caused the death of people who would not have died without these weather events, especially in cities. Current knowledge regarding the exact number of heat-related deaths and hospital admissions for Scotland is very limited. It is estimated that there are 70 estimated heat-related deaths per year in Scotland. It is also assumed that impacts in southern Scotland may be similar to those observed in northern England. The number of deaths from heat are expected to rise in Scotland and the rest of the UK too.

Economic impacts

Agriculture In some cases, Scottish agriculture may experience a positive change as summers will be warmer and drier. A higher yields and the possibility of new crops being able to grow in Scotland. However, soil quality would lower with heat and soil moisture stress. The availability of fresh water could cause problems for livestock. Heat stress with warmer and wetter conditions, livestock could face new diseases such as West Nile virus and outbreaks of bluetongue or parasites could increase.Scotland's Climate Change Adaption Framework – Agriculture, Scottish Government.[Accessed 1 May 2010]

Mitigation and adaptation

Policies and regulation

Climate Change Act

The Climate Change (Scotland) Act 2009 is an Act passed by the Scottish Parliament.Climate Change (Scotland) Act 2009, London, HMSO. [Accessed 1 May 2010] The Act includes an emissions target, set for the year 2050, for a reduction of at least 80% from the baseline year, 1990. The Climate Change (Scotland) Act 2009 was amended by the Climate Change (Emissions Reduction Targets) (Scotland) Act 2019, increasing the ambition of Scotland's emissions reduction targets to net zero by 2045 and revising interim and annual emissions reduction targets. Annual targets for greenhouse gas emissions must also be set, after consultation the relevant advisory bodies. Provisions are included in the Act for the creation of the Scottish Committee on Climate Change, as at present the only advisory body is the UK Committee on Climate Change.http://www.scotland.gov.uk/Topics/Environment/climatechange/scotlands-action/climatechangeact/advisorybody Advisory Body Ministers in parliament must now report on the progress of these targets.Scottish Government report on 2010 emissions. As of January 2011, public sector bodies in Scotland must comply with new guidelines set out by the Scottish Government.http://www.scotland.gov.uk/Topics/Environment/climatechange/scotlands-action/climatechangeact/publicsector Duties on public sector bodies

Protection and enforcement

The Scottish Environment Protection Agency (SEPA) is Scotland's environmental regulator.Scottish Government, Scotland's Higher Activity Radioactive Waste Policy: Consultation 2010, Part 7, 5.02.02 [Accessed 29 April 2010]Environment Act (1995). (c.2), London, HMSO [Accessed 29 April 2010].LE Law and Your Environment, The plain guide to environmental law website [Accessed 29 April 2010]The UK Environmental Law Association website [Accessed 29 April 2010] SEPA's main role is in protecting and improving Scotland's natural environment. SEPA does this by helping communities, businesses and industries understand their legal and moral responsibilities they have relating to the environment.

SEPA recognises that climate change is the single greatest threat to our future. The organisation has produced its own climate change plan which contains details about how it will reduce its carbon emissions.SEPA's Climate Change Plan [Accessed 1 May 2010] This five year climate change plan introduces SEPA's specific role in climate change mitigation. SEPA, Scottish Natural Heritage (SNH), Forestry and Land Scotland (FLS), Scottish Forestry and Historic Environment Scotland are all government funded organisations with responsibilities for different aspects of Scotland's environment and heritage. A joint statement on climate change was created by all partners in 2009.Action on Climate Change – joint statement of intention publication, 2009 , SEPA, SNH, Historic Scotland, FCS [Accessed 30 April 2010]

International cooperation

During a 2017 visit to the United States, the first minister Nicola Sturgeon met Jerry Brown, Governor of California, where both signed an agreement committing both the Government of California and the Scottish Government to work together to tackle climate change.

The COP26 climate conference was held in Glasgow in 2021.
