The National Trust emphasizes that the disruption of predictable weather patterns is creating disorder in nature.Â
The organization cautions that climate change is disturbing the customary seasonal rhythms, rendering plants and wildlife more vulnerable to diseases.
These impacts are observable across the estates managed by the National Trust, as the shifting seasonal baseline disrupts the annual behaviors of animals and also affects trees and plants.
“The incremental shifts we’re experiencing in terms of our seasons extending may not feel like much in a 12-month period, but over a decade the changes are extremely significant”, said Ben McCarthy, head of Nature and Restoration Ecology at the National Trust.
In 2023, a series of temperature records were set, including the warmest June and highest sea temperatures ever recorded around the UK coast.
An unusually warm winter provided favorable conditions for the proliferation of pests and diseases.
Simultaneously, low water levels in rivers, lakes, and reservoirs—resulting from a combination of minimal rainfall and high temperatures—contributed to an increase in algal blooms.
On certain occasions, this phenomenon led to mass fish deaths as plummeting oxygen levels caused suffocation.
Dramatic storms, such as Babet and Ciaran, caused damage to landscapes and coastlines across the country.
The impact of these seasonal changes is noticeable in parks and gardens, where grass requires mowing much later into the year.
National Trust rangers and gardeners attribute this shift to the progressively warm and wet conditions observed at their sites in England, Wales, and Northern Ireland.
Elevated temperatures have triggered early blooming in certain shrubs, rendering them vulnerable to abrupt cold spells. This phenomenon impacts pollinators and the birds relying on their seeds.
The iconic oak tree in the UK may face significant challenges due to the escalating year-round temperatures, cautions Mr. McCarthy.
Shortening durations of cold snaps often do not provide sufficient time to eliminate diseases.
