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 |
