Spain's Record Rainfall Sparks Renewed Chemtrail Debate

Fewer Contrails and Record Rain: The Coincidence Under Debate

A participant argues that Spain emerged from drought and hit a rainfall record just as skies stopped showing persistent airplane trails. This coincidence—a country moving from drought to full reservoirs exactly when contrails become less visible—has reignited one of the most recurring debates: that of so-called estela, alleged sprays attributed by some to geoengineering, which meteorological science reduces to simple condensation trails.

The thesis of change is easy to state. According to some participants, during drought years, the sky was covered in white trails that expanded into high fog and sticky heat that prevented sleep. Now, those who trinc the phenomenon daily claim these trails have nearly disappeared and rains have returned. The common tracking source is the public reservoir register.

Why Trails Appear Sometimes and Not Others

The meteorological explanation requires no conspiracy. Contrails form at high altitudes where air is very cold and moisture condenses into ice crystals passing through engine exhaust. What matters is not ground-level weather, but temperature and humidity at around 32,000 feet. This detail dismantles the most repeated observation: that if there are -5 degrees and 87% relative humidity on the runway, planes should leave visible traces just like at altitude.

The key lies in the upper atmosphere. Cold northern air has less capacity to retain moisture the higher you go, so an airport near the Mediterranean accumulates more chances of generating persistent contrails than one in Arctic latitudes. Add instability: chaotic upper winds break and dissipate the trail before it can be seen as a long line.

The most uncomfortable argument for the conspiratorial version remains the same: if upper atmospheric humidity conditions explain the phenomenon, no one needs to spray anything for a sky to be streaked one day and clear the next.

Does It Make Sense to Spend Millions to Clear Clouds?

Here the debate enters economic territory. The objection repeats itself: flying giant tanks and complex chemicals to keep the sky clean is a ruinous business. Kerosene costs money, and ultimately taxpayers would pay. The response from the other side is that money is not a problem when spending is already socialized.

Two explanations circulate regarding the recent drop in contrails, neither confirmed. The first points to the closure of USAID, which allegedly cut off a funding source. The second suggests that the firm BlackRock stopped investing, and shortly after, contrails declined. Both are mentioned as suspicions, not proven facts.

The detail that breaks the logic of the accusation is internal contradiction: the same phenomenon has been blamed for causing drought and for causing rain. A mechanism that causes both things simultaneously is not a mechanism; it is a catch-all excuse.

Spanish Law Already Allows Modifying Rain, With Permission

There is a regulatory fact often overlooked: artificial modification of the hydrological cycle is not illegal fantasy; it is regulated. A participant cites Article 3 of the Water Act, according to which the atmospheric phase of the hydrological cycle may only be artificially modified by the State Administration or those authorized by it.

Any action, public or private, aimed at modifying rainfall regimes requires prior approval from the relevant Ministry, proposed by the basin authority and with a report from the National Meteorology Institute. In other words, modifying rainfall regimes is a legal activity with administrative procedures.

The patent cited repeatedly in this discussion is old: in 1951, two former US Navy pilots registered a procedure based on substance dispersion to modify weather. That the technique exists and is documented does not miccionan every contrail in the sky is a secret program.

From 40 Degrees in 2022 to the Skies of 2025

Chronology matters. Summer 2022 was marked by heat described by a participant as unbearable: permanent 40 degrees in the shade and 30 degrees at night, with streets turned into furnaces and contrails expanding overhead into a whitish layer. That same year, some attributed the heat to the eruption of the Hunga Tonga volcano and its injection of water vapor into the stratosphere.

Another participant describes cooler summers and a repeating pattern: July months where one sleeps with thick blankets, skies with fewer lines, and a general feeling that 'something has changed up there.'

The last documented episode places the discussion in May 2025. A graphic record dated 25/05/2025 showed Barcelona's sky 'completely shattered' by contrails spreading across the firmament. The drop in contrails is therefore not uniform or definitive: it depends on the day, the city, and the height from which one looks.

Is upper atmospheric humidity enough to explain why some years have streaked skies and others have clear ones?
