Research carried out wholly or partly by volunteers — and the answer to whether it produces real data is yes, demonstrably, provided the project is designed for it, which is the entire determinant.
Real, frequently overstated in viral claims, and concentrated in places most people do not expect — the network and the device, not the data centre alone. Where the energy actually goes: data
Finance directed towards environmentally beneficial activity — and a green bond is its most visible instrument: a normal bond whose proceeds are earmarked for qualifying projects. How a green bond
It depends entirely on what is certified, by whom, and against what standard — and the range runs from rigorous third-party audit to a logo a company designed itself. The questions that separate
The combination of heat, humidity and duration — and humidity is the part people underestimate, because it determines whether the body's only real cooling mechanism still works. How the body cools.
For several quite different reasons, and "there is no wind" is only one of them — the others are more interesting and are routinely misread as evidence that the technology does not work. The reasons,
Ground that has remained frozen for at least two consecutive years — covering roughly a quarter of the northern hemisphere's land — and its thaw matters because of what has been locked inside it for
A band of very fast winds high in the atmosphere that steers weather systems — which is why its position, not any single storm, determines whether a region gets weeks of rain or weeks of sunshine.
Because three separate trends have compounded: more flammable landscapes, more ignitions, and hotter drier conditions — and the first of those is frequently the most important and the least
Measuring your energy use at short intervals and sending the readings automatically — and the genuinely consequential part is not the display in your kitchen but what half-hourly data makes possible.
A flood plain is the flat land beside a river that the river floods — not occasionally and unluckily, but as its normal behaviour over geological time. Flooding is getting worse because of what has
A network of insulated pipes carrying hot water from a central source to many buildings, replacing individual boilers. It is efficient not because the heat is better but because scale unlocks heat
Most of it is far less dramatic than the word suggests, and the genuinely difficult fraction is small in volume, enormous in longevity, and currently stored rather than permanently disposed of in
From a small number of countries and a smaller number of processing facilities — and the impacts are real, geographically concentrated, and substantially smaller per unit of energy delivered than the
An area of sea where human activity is restricted for conservation. They work when they are genuinely protected, enforced, and large enough — and a great many are none of those things, which is why
Because the problem is energy density, and no alternative currently matches jet fuel closely enough for long flights — which is why aviation is one of the genuinely hard sectors rather than a matter
From rivers, reservoirs or underground aquifers, through a treatment sequence that has changed remarkably little in principle for a century — and which is among the largest public health
Most of both is recyclable, and the awkward parts — blade composites and laminated solar glass — are the ones that genuinely are not yet handled well at scale. Wind turbines. Around 85–90% of a
Capturing carbon dioxide and putting it underground permanently. The technology demonstrably works; the contested questions are cost, scale, and whether its availability delays cutting emissions in
By matching generation to demand continuously, because electricity is consumed at the instant it is produced and the grid stores essentially none of it. The balance is visible in a single number:
Unwanted or harmful sound in the environment — and it matters considerably more than its reputation suggests, because the health effects operate whether or not you are consciously annoyed by it,
Because several pressures act simultaneously on the same populations, and the combination matters more than any single cause — which is also why the problem is hard to fix with one intervention. What
Legal action brought to compel climate action or establish liability for climate harm — a field that barely existed two decades ago and now comprises thousands of cases worldwide, several of which
The Conference of the Parties is the annual meeting of countries that signed the UN climate convention — the forum where international climate agreements are negotiated. Its results are genuinely
