Climate and Ecology
Climate and ecology are my Roman Empire — I think about them every day. Climate change is the defining issue of the 21st century, an existential challenge for humanity. There is no hiding from the future.

The fight for a brighter climate future is what I do almost daily. Even with my limited resources, I believe I know how to maximize my impact. This page records my convictions and plans.
The climate crisis
I am convinced that climate change is real and undeniable. Never before has the Earth faced such a rapid rise in greenhouse gas concentrations as in the past two centuries. The biosphere is vast and inert, but its capacity to absorb excess heat is not infinite. Already in this century, we will face catastrophic consequences to which neither ecosystems nor humanity will be able to adapt.

I am an informed pessimist, and therefore I am sure: the future will be difficult, and the world will not return to "how it used to be". Many regions will become uninhabitable — in some places because of droughts, in others because of sea level rise, and in yet others, such as the Persian Gulf, because of the lethal combination of extreme heat and humidity. This will drive large-scale climate migration, the magnitude of which we can hardly imagine today.

Yet acknowledging this truth is not only painful, it is also a source of strength. Honesty allows us to see the scale of the threat more clearly and to find ways to mitigate it. Every step, even the smallest, increases our chances of survival as a species and gives us the opportunity to preserve more ecosystems than if we did nothing at all.
Key positions
The future of energy
The foreseeable future belongs to solar and wind power, which make energy systems more resilient and decentralized. Existing hydropower should remain, but building new dams is best avoided. I am also convinced of the necessity of nuclear energy: with the right approach, it provides stable capacity and can serve as the backbone of energy balances. It would be wise to invest more actively in new generations of reactors. Finally, I believe that in the 21st century nuclear fusion will become a mass technology and bring about an energy revolution.
Phasing out coal and false biofuels
The priority now is to phase out coal. No other fuel source takes so many lives and causes so much harm to the environment. Where an immediate switch to renewables is not possible, coal should at least be replaced with gas. Pressure must be applied to coal companies, to banks, and to states that continue subsidizing this business.

At the same time, we must debunk the myth of "green" biofuels: fuels made from crops and pellets from specially felled trees are greenwashing. This so-called biofuel simply takes away farmland and drives deforestation.
Greenhouse gases and geoengineering
CO₂ is the key greenhouse gas, but methane already accounts for about a third of observed warming. Methane is dozens of times stronger than CO₂ in the short term. It leaks during coal, oil, and gas extraction, and is released from thawing permafrost. The more methane in the atmosphere, the faster the warming, which in turn causes even more methane emissions. It is a vicious circle — and in this sense, fighting methane is no less urgent than cutting CO₂.

Since we cannot wake up tomorrow in a world with zero emissions, humanity will have to turn to geoengineering. Carbon capture today is energy-intensive, and it is more rational to direct the clean energy we have toward replacing dirty generation. Controlled use of sulfate aerosols could temporarily cool the Earth and buy us time for the green transition. All potential risks pale compared to the benefits.
Energy abundance
If humanity achieves an abundance of clean energy (most likely through nuclear fusion), it will open radical new possibilities: desalinating gigatonnes of seawater, transforming degraded land for agriculture, and freeing up valuable ecosystems for nature. With responsible use of science and technology, we could shift from being destroyers to becoming creators.
Nature and resources
I am convinced that large territories must remain untouched. Humanity should not exploit every free patch of land. The exploitation of Greenland, Antarctica, the destruction of all tropical forests, and deep-sea mining are thresholds we must not cross. These fragile ecosystems do not recover for decades.

Planning land use should be done with centuries in mind: we should not build near the rising seas, nor convert river floodplains — vital filters of biodiversity — into fields or summer house settlements. Hunting whales, dolphins, and large animals must be globally banned. We need to promote the idea that trophy hunting is an atavism.
Materials and waste
The myth of plastic recycling benefits packaging and beverage producers: as long as people believe in recycling, the industry can keep running business as usual. But in reality, many plastics are polluted with chemical additives and are poorly recyclable, while a large share ends up in landfills, gradually breaking down into microplastics.

It is more honest to acknowledge these limitations and destroy plastic at high temperatures, while in the future — with energy abundance — synthesizing new polymers from the air and closing the cycle on truly sustainable terms. Today, however, we should prioritize materials that can genuinely be reused: aluminum and glass. They may be heavier and less convenient for logistics than plastic, but they have one decisive advantage — they can be recycled virtually endlessly without losing quality.
The future of food, science, and society
I do not believe humanity will completely give up meat, but I do believe in alternatives: proteins from insects, lab-grown meat, and even mushrooms as a new source of protein. Technology will inevitably make these sources cheaper than traditional animal farming.

In a world of energy abundance, states that produce oil, gas, and coal will lose the "easy money" that today fuels corruption and dictatorships. This will not only reduce the likelihood of wars, but also free enormous resources for science, technology, and social development.

Europe has a special role to play: as a mega-market, the European Union can dictate environmental standards to the world and use trade to drive global change.
My path
I feel that my contribution will be greatest if I focus on explaining complex issues of climate and ecology and on popularizing knowledge. Through Wikiganda, I can make important matters a little clearer. Sometimes this means talking about big global trends, and sometimes about specific natural sites that need protection.

A brighter future has its enemies: corporations, lobbyists, and politicians invested in maintaining the status quo. They have vast resources and know how to protect their interests. Them I will expose.

But the future also has allies: scientists, research and environmental organizations, companies advancing clean technologies, and responsible politicians — all those who invest time and resources to prevent the world from collapsing. Them I will help by telling their stories.
