Where Earth's climate system breaks, mapped against the technologies working on each threshold. Research and opinion — not investment advice.
Read each bar as a range of possible tipping temperatures — the wider the bar, the less certain the science. Vertical guides mark the Paris targets and where current policies are heading. Click any element for its full record.
A note on scaleThe last time CO₂ sat near today's level (~420 ppm) was the mid-Pliocene, roughly 3 million years ago, when seas stood some 10–20 m higher. We are steering the planet toward a climate it last knew before modern humans existed.
Three things describe a technology's position here: a technology’s potential climate impact (vertical), the funding it already attracts (horizontal), and how ready to deploy it is (marker size — bigger is more mature). The shaded upper-left is the sweet spot: high potential, low funding. Large markers there are the clearest cases of impact outrunning capital. Red marks technologies that per-technology assessments (cited on each card) flag as neglected relative to their potential. Potential impact is a directional assessment synthesized from the sourced figures (Gt CO₂/yr where it exists), not a precise number. Click any marker or card for the full record.
No technology refreezes an ice sheet or restarts an ocean current. Leverage means lowering how far past each threshold we travel — by cutting the warming and turning waste carbon into value.
Of every technology charted in the section above, MES scores the most modest potential climate impact. It is an early-stage contributor to the emissions & industrial-carbon lever — not a planetary thermostat. Its real role: treating waste streams while generating energy, converting CO₂ into usable chemicals, and recovering metals and nutrients. It shrinks footprints and closes loops; it does not touch ice sheets or ocean currents directly, and it will not move the thresholds charted above on its own.
A modest-impact technology can still belong in a portfolio. MES already works at pilot-to-industrial scale (TRL 7) on problems — waste treatment, metal recovery — worth solving regardless of whether the field ever reaches gigatonne scale. That is a smaller, more defensible claim than the "underfunded, high-leverage" case made for the technologies above, and it's the one MES can actually support.
Warming is still the master lever — every threshold on this page moves with it, and nothing below changes that. But within the technologies people are already funding, impact and capital aren't currently aligned: atmospheric methane removal, direct ocean capture, and blue carbon restoration sit in the underfunded sweet spot, while direct air capture absorbs a disproportionate share of climate money for a comparable slice of potential impact. If you take one thing from this page, take this: look at where the gap between impact and funding is widest, and treat that gap — not the loudest technology — as the signal.
