McKinsey Global Institute: Climate planning has prioritized floods. Heat demands equal attention

Record heat in Europe and a US “heat dome” are driving immediate infrastructure and health strain and highlighting a large adaptation gap: only 18% of people in heat-stress areas have access to air-conditioning, while global adaptation spending is about $190B/year protecting 1.2B people. Scaling protection to all 4.1B people exposed to heat/drought/wildfire/flood hazards would cost about $540B/year (roughly 3x current spending), and protecting all hazards at 2°C warming could reach ~$1.2T/year with ~60% for heat adaptation. The article frames adaptation as a strategic/operational imperative for businesses, implying rising demand opportunities for cooling, resilient infrastructure, and related technologies, but also near-term costs and risk exposure as heat intensifies.

Analysis

The investable edge is not in “climate” branding; it is in dull, recurring retrofit spend that gets pulled forward when operating uptime matters more than efficiency. That favors incumbents with distribution, service networks, and installed bases — HVAC, controls, switchgear, backup power, and grid-hardening names such as CARR, JCI, ETN, and PWR — because the spending is likely to show up first in replacement and emergency work, where margins are better than on greenfield projects.

The losers are mostly second-order: labor-intensive businesses with outdoor exposure and weak pricing power, plus utilities and insurers that absorb higher operating losses before they can re-rate tariffs or premiums. For utilities, the near-term hit is opex and reliability spend; the longer-term effect is capex crowd-out, which can pressure dividend growth if regulators slow cost recovery. For insurers/reinsurers, this is less about a single catastrophe than a steadier rise in attritional claims and business-interruption severity over multiple seasons.

Contrarian view: the market often overbids for “clean-tech” narratives while underpricing the boring supply chain that actually sells resilience. The biggest upside is likely in retrofit, controls, and service, not in novel adaptation tech. This looks more like a 6-18 month capex and aftermarket cycle than a one-day trade; it fails if order books and management commentary do not reaccelerate after the summer peak, or if customer budgets treat adaptation as discretionary maintenance rather than essential uptime spend.

Key Decisions for Investors

• Long CARR and JCI on pullbacks over the next 1-3 months; target 10-15% upside if summer-driven retrofit demand shows up in backlog and pricing, with the thesis invalidated by any two consecutive quarters of flat-to-down organic orders.
• Long ETN as a 6-18 month structural beneficiary of backup power, switchgear, and grid-hardening spend; expect a better multiple if investors start underwriting resilience capex as a secular rather than cyclical tailwind.
• Long PWR as the purest infrastructure-resilience compounder; use a staggered entry because the rerating may come with municipal/utility budget visibility over 2-4 quarters, not immediately.
• Pair trade: long CARR / short KIE as a hedgeable way to express “adaptation winners vs. climate-loss liabilities”; if the thesis is right, the spread should outperform into next summer’s earnings cycle.
• Set a watch item on utility capex guidance and HVAC order growth next quarter; if neither inflects, reduce exposure because the market may already be paying for a resilience story that remains mostly thematic.
