Why Is It So Warm In Europe – A Lack Of Pollution!
The Irony of a cleaning up energy is the pollution reflected back sunlight. Take away the pollution and more of the suns rays reach the earth’s surface.
I got in my car and put the key in the ignition, and I was not surprised to see the outside temperature was showing 41oC. Date 9th July 2026. Location Wakefield England not known for being remarkably hot.
The Solution? – More Trees and Wetlands (slow run-off after rain)
1. How Planting Trees Cools the Climate
Trees cool the atmosphere through three main mechanisms:
Evapotranspiration (Nature’s Air Conditioner): Trees pull liquid water from deep in the soil and transpire it as water vapour through their leaves. This phase change absorbs heat energy from the surrounding air (converting sensible heat into latent heat). A single mature tree can transpire hundreds of gallons of water a day, lowering ambient air temperatures in its vicinity by 2°C to 8°C (3.5°F to 14°F).
Shade and Ground Coverage: Canopy shade prevents direct sunlight from striking and heating up bare ground, rocks, or asphalt, drastically reducing the heat radiated back into the local environment.
Carbon Sequestration: Over long timescales, growing forests absorb atmospheric carbon dioxide ($\text{CO}_2$), mitigating the primary driver of global warming.
2. How Slowing Rainwater Cools the Landscape
When rain falls on degraded land or paved urban surfaces, water drains away rapidly into streams and oceans. This leaves the landscape dry, baked by the sun, and prone to rapid surface warming.
Slowing down rainwater using wetlands, swales, leaky dams, and healthy soils reverses this process:
Fast-Drain Landscape | Slowed / Retained Landscape |
Water flushes out in hours | Water sinks into aquifers and soil reserves |
Soil dries out rapidly; heat builds up | Sustained moisture allows continuous evaporative cooling |
Increases risk of flash floods & heatwaves | Buffers local climate against extreme heat and drought |
Beavers! We Need More Beavers Than Ever Before In Europe
- “The Busy Beavers Bringing Wetlands Back to the UK” | WILD HOPE (Nature on PBS)
- Creator: Nature on PBS
- Why watch: Part of the Wild Hope series, this video follows conservationists reintroducing Eurasian beavers to depleted UK landscapes. It provides clear field footage showing how quickly beaver dams capture runoff, saturate parched subsoil, and turn dry ditches into resilient, water-retaining sponges.
“We Let Beavers Transform an Old Farm”
Creator: Planet Wild (in collaboration with Rewilding Oder Delta)
Why watch: A practical, team-led project that bought an abandoned, dry fish farm in Poland and allowed a family of beavers to re-engineer the landscape. It features real conservationists explaining the hydrology of how beaver dams retain surface water and slow streamflow.
There are many more beaver videos on YouTube – the story is the same, by slowing down the flow of water with small dams – more water soaks into the ground which is released over time, reducing the temperature in the surrounding area and reducing the risk of fires. The scientific word for this is the Albedo rate.
Albedo measures how effectively a surface reflects solar radiation, expressed as a value from 0 (a theoretical “blackbody” that absorbs 100% of light) to 1 (or 100%, a perfect reflector that bounces all light back). High-albedo surfaces like fresh snow (0.80–0.90) and bright ice reflect the vast majority of incoming sunlight, keeping the surrounding local environment cool. Conversely, low-albedo surfaces like dark asphalt (0.05–0.20), dense pine forests, and open ocean (0.06) absorb most of the sun’s shortwave radiation, storing it as heat and warming the local area. This physical property powers a critical climate loop known as the ice-albedo feedback: as global temperatures rise and dark land or open water replaces bright, reflective ice, the surface albedo drops, causing the planet to absorb even more thermal energy and accelerating local and global heat retention.
Dry land heats up much quicker than wet marshy land. Ironically after centuries of draining farmland we need to make some of that land much wetter.
