Decades-old and long-debunked myths about so-called chemtrails have become a central part of a wild conspiracy theory that falsely asserts the US government used non-existent weather manipulation technology to create the devastation caused by Hurricanes Helene and Milton.
As myths about Milton and Helene spread, interest in chemtrails increased too on Google search and social media. Chemtrail conspiracy theorists falsely believe condensation trails (known as contrails) left behind by aircraft in the sky are full of toxic chemicals spread by the government to control the weather or control people's minds.
In reality, scientists say contrails appear when water vapor condenses and freezes around the exhaust from an aircraft.
The virality the conspiracy theory has achieved online in the last couple of weeks has never been seen before and is a cause for concern, climate and weather experts tell CNN.

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.
Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.
Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.
Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.
The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
