Indy Johar argues that humanity's first view of Earth from space initiated "planetary self-awareness," urging us to reimagine civilization as a global endeavor. Facing climate instability and AI's transformative impact, he advocates for "civilizational optionality"—a buffer against cascading shocks. He suggests embracing our limited knowledge fosters curiosity, tenderness, and care.

Johar envisions human-machine systems enhancing our capacity for complex discourse, defining intelligence as a conversational field for collective sense-making. This talk, presented January 27, 02026, is part of the Long Now Talks series, which fosters long-term thinking.

Join award-winning architect and environmentalist Duncan Stewart for a talk on the challenges of greenhouse gas emissions. He will discuss their impact on Earth's climate, the future of our youth, and biodiversity, along with potential solutions.

A pioneer in sustainable architecture, renewable energy, and nearly zero-carbon buildings, Duncan is a director of the Irish Environmental Network, Dublin Civic Trust, and Green Foundation Ireland. He also produces and presents RTE 1's 'Eco Eye' and 'About the House'.

Hosted by Duncan Stewart, the 'Take, make, dispose' model describes our current linear economy: extracting raw materials, making products, then discarding them. This 20th-century consumerism has led to dwindling resources, overflowing waste, and significant environmental damage.

In contrast, the Circular Economy offers a progressive, efficient, and environmentally friendly alternative, mimicking nature by eliminating waste. The final Eco Eye series 12 program explores this model, showcasing Irish companies adopting it and featuring experts discussing its challenges and opportunities.

Ireland's public sector spends €9 billion annually on goods and services, totaling €100 billion over the next decade. This significant public expenditure presents a crucial opportunity to reduce carbon footprint, conserve energy, and boost environmental awareness among citizens.

Dublin fireman Neil McCabe demonstrates how this investment could foster environmentally friendly buildings and generate substantial cost savings. Transitioning to a green, low-carbon economy would not only save money but also create jobs.

The question remains whether local authorities and the government will embrace this vision. This discussion, hosted by Duncan Stewart, was published on Feb 18, 2014.
