‘It’s pretty bleak’: A warming planet is poised to get even hotter, forecasters warn

A UN report forecasts a high likelihood of average global warming exceeding 1.5°C above pre-industrial levels within the next five years, potentially as early as 2029, increasing the risk of extreme weather events like droughts, heat waves, and intense wildfires, particularly in regions like the western U.S. The report, based on over 200 forecasting models, also highlights the potential for significant economic and ecological impacts, with some areas facing rapid Arctic ice melt and others experiencing climate "whiplash" between wet and dry conditions. These projections come as the U.S. faces potential budget cuts to NOAA and a rollback of climate science initiatives, further hindering mitigation and forecasting efforts.

Analysis

The World Meteorological Organization's latest report projects a high probability that global average temperatures will exceed the 1.5°C Paris Agreement threshold above pre-industrial levels within the next five years (2025-2029). There is an 80% chance that at least one year in this period will surpass 2024 as the warmest on record, an 86% likelihood that at least one year will exceed the 1.5°C (2.7°F) warming mark, and a 70% chance the entire five-year average will do so. These projections, derived from over 200 forecasting models, indicate severe consequences, particularly for regions like the western U.S., which faces increased risks of drought, heat waves, and more intense, prolonged wildfire seasons, continuing a trend where the last 25 years were the driest since 800 AD. Globally, impacts include rapid Arctic sea ice thaw, drier Amazonian seasons, agricultural failures, and more frequent climate "whiplash" events, leading to growing negative effects on economies and ecosystems. This challenging outlook is compounded in the U.S. by a policy environment characterized by a proposed 25% budget cut to NOAA for 2026 ($1.5 billion), staff reductions impacting disaster forecasting, a withdrawal from the Paris Agreement under the Trump administration, and the suppression of climate science communications and research, including the dismissal of experts from the National Climate Assessment.

Key Decisions for Investors

• Re-evaluate exposures to assets in regions prone to escalating climate impacts, such as the western U.S., particularly in sectors like agriculture, insurance, and real estate, due to heightened risks of drought, wildfires, and heatwaves.
• Explore investment opportunities in climate adaptation technologies, resilient infrastructure, and water management solutions, as demand for these is likely to increase with the projected intensification of extreme weather events.
• Closely monitor U.S. policy shifts regarding climate science funding, such as the proposed NOAA budget cuts, and environmental regulations, as these changes, including rollbacks under the current administration, could significantly impact the operational environment and risk profiles for various industries.
• Heightened scrutiny of companies' climate risk disclosures and adaptation strategies is warranted, given the increasing frequency and severity of climate-related disruptions forecasted by the WMO and the potentially reduced governmental capacity for disaster forecasting.
