Because they lied to us. Their aim was control. It worked with many. This article is about climate "experts" and why they are not trusted so much. Many example below.
Why isn't our media reporting on Sir Lanka? Because the mass riots were caused by the climate "experts" and their famines. It goes against the legacy media's agenda.
Why We Lost Trust in the Expert Class (townhall.com)
For years, European policymakers had assured the world that the relatively rapid "transition" to "green" energy was the world's preordained future -- regardless of the costs.
Accordingly, many European Union governments followed the advice of green experts. They eagerly shut down coal, natural gas, and nuclear power plants to transition immediately to "renewable energy."
Most citizens were afraid to object that in cloudy, cold Germany solar panels were not viable methods of electrical generation -- especially in comparison to the country's vast coal deposits and its large, model nuclear power industry.
As a result, German government officials warn that this winter, in 19th-century fashion, families will have to burn wood -- the dirtiest of modern fuels -- to endure the cold. And there is further talk of "warm rooms," where like pre-civilizational tribal people, the elderly will bunch together within a designated heated room to keep alive.
Sri Lanka may be the first modern nation to adopt deliberate policies that have led to mass hunger and bankruptcy. The government, for a variety of reasons, listened to foreign advocates of back-to-nature organic farming, specifically outright abandonment of highly effective synthetic fertilizers and pesticides.
The result was endemic crop failure. Cash crops for export failed. Widespread hunger followed. Without foreign exchange, it became impossible to import key staples like food and fuel.
Sri Lanka once had a per capita income twice that of nearby India. Now it cannot feed or fuel itself.
