Technology focused on climate change (operating independently) cannot rescue us

The world of climate technology, often referred to as the 'climate tech' sphere, is currently experiencing a surge in investment and innovation, reminiscent of a second clean tech bubble. This boom, however, is accompanied by significant concerns about its sustainability and realistic outcomes.

According to recent reports, the current climate tech bubble is more extreme than the previous cleantech boom in the early 2000s. The WilderHill clean energy stock index rose from 47 in March 2020 to 281 less than a year later. Silicon Valley invested over $50 billion in clean energy startups in 2021 alone, more than twice the amount invested from 2006-2011 during the first bubble [1].

This bubble, like its predecessor, shows signs of overvaluation and speculative frenzy. For instance, the battery company QuantumScape was valued higher than General Motors despite no sales, until its stock then crashed more than 95% from its high. Several electric vehicle startups faced financial distress or bankruptcy, and major oil companies began scaling back clean energy investments, similar to patterns observed after the first cleantech bubble [1].

The main mistake of investors has been over-reliance on aggressive growth projections. Entranced by extravagant forecasts, they failed to account for the likely sigmoid (S-curve) growth of energy transitions, which naturally slow after early rapid phases [1].

Despite these concerns, climate tech investment continues robustly into 2025. This persistence is due to new technologies like AI-driven cleantech innovations and commercial advancements in fusion energy, suggesting a complex picture rather than a pure bust scenario. Fusion projects, for example, are showing commercial traction and attracting global investment beyond traditional markets [2].

The current climate tech growth is intertwined with urgent climate challenges and policy needs, including geoengineering research and planetary security considerations, reflecting high stakes beyond mere market speculation [3]. However, concerns focus on whether market enthusiasm accurately reflects the complex timelines and risks inherent in energy transitions, not just on outright market collapse [1][2]. Investors and markets are urged to remain cautious of inflated expectations while supporting viable innovations.

The climate tech sphere remains predominantly white in membership and workforce, a concern that echoes the broader tech industry. The financial infrastructure supporting climate tech could be redirected towards human capital, such as incubating the next generation of climate activists. Local farmers, growers, and stewards hold the knowledge needed to sustainably fish, improve soil health, and regenerate forests, yet their voices are often overlooked in the rush for quick profits.

In conclusion, the "climate tech" sector mirrors a second clean tech bubble with dramatic investment surges, valuation excesses, and subsequent corrections. However, because of technical innovations and continued demand linked to climate imperatives and AI integration, concerns focus on whether market enthusiasm accurately reflects the complex timelines and risks inherent in energy transitions, not just on outright market collapse [1][2].
