Global Extreme Weather and Climate Change Dashboard
Oceania
Oceania accounts for 2.4% of global weather/climate economic losses and 0.2% of deaths, 1980-2025 (see Loss Normalization), broken down by phenomenon and cause below. This page also runs an IPCC AR6 Chapter 12 consistency check phenomenon by phenomenon, and hosts every live-computed variable this dashboard tracks at continent scale for Oceania -- not every phenomenon runs for every continent; see the "Not Yet Available" note below for what Oceania's source data doesn't yet support.
Summary Judgment — Oceania
– of – tracked variables for Oceania show a detected change (– increasing, – decreasing) — see the tiles below for each one.
AR6 reports opposing observed drought trends within Australia itself (decreasing in the north, increasing in the south) — plausibly why the continent-wide index here shows no detected change, since regionally opposite signals can net out in an aggregate. AR6 also reports an observed, continent-wide increase in fire weather days since 1950, while the burned-area and dry-matter-combusted metrics tracked here both show no detected change for Oceania — the same fire-weather-vs-realized-fire distinction drawn on the Wildfire page, not a contradiction.
Source: AR6 WGI Regional Fact Sheet — Australasia — this site detects observed historical trends only, never projections, so this comparison draws only on AR6's observed findings, excluding its projected ones.
Consistency with IPCC AR6 Chapter 12
Each phenomenon this site tracks for this continent, checked against AR6 WG1's Chapter 12 regional fact sheet -- see the Summary Judgment above for the fuller narrative version of this same comparison.
| Phenomenon | GWX finding | AR6 Ch.12 consistency |
|---|---|---|
| Drought | Computing… | Consistent |
| Flooding | Computing… | Not directly comparable |
| Wildfire | Computing… | Not directly comparable |
| Tropical Cyclones | Computing… | Partially consistent |
Each note above draws only on AR6's observed findings, excluding its projected ones, the same standard the Summary Judgment box applies. Source: AR6 WGI Regional Fact Sheet — Australasia.
Economic Losses & Loss of Life — Oceania's Share
Oceania's position within the same global economic-loss and mortality totals shown on the Loss Normalization page -- not a separate, continent-specific breakdown by phenomenon (no source publishes a full continent x phenomenon matrix; OWID and the World Bank give continent totals and phenomenon totals separately, not both at once). This page reuses those continent-level numbers, calling out Oceania's row.
Economic losses, 1980–2025
Oceania accounts for 2.4% of global weather/climate economic losses.
- North America $2,913.4B 51.2%
- Asia $1,833.3B 32.2%
- Europe $584.4B 10.3%
- South America $162.6B 2.9%
- Oceania $134.5B 2.4%
- Africa $60.1B 1.1%
Loss of life, 1980–2025
Oceania accounts for 0.2% of global weather/climate deaths.
- Asia 663,197 37.5%
- Africa 642,787 36.3%
- Europe 337,192 19.1%
- North America 65,487 3.7%
- South America 56,280 3.2%
- Oceania 3,767 0.2%
Both pies are constant-2025-dollar / EM-DAT totals, same sourcing and methodology as the Loss Normalization page -- see that page for the full reconstruction methodology, inflation adjustment, and citations.
Extreme-weather and climate trends for Oceania, drawn from the same underlying data as GWX's global variables, aggregated (or, for tropical cyclones, grouped by the ocean basin(s) that border this continent) to just this continent rather than the whole planet. Not every phenomenon this site tracks has a per-continent breakdown yet (see below for what's still missing and why) -- the tiles here show only a computed Oceania-scoped index, never a global figure relabeled. Clicking a tile opens that variable's full interactive chart, scoped to Oceania. See the Methodology page for the full per-continent coverage status behind what appears here and what doesn't.
Detection of Long-Term Change — Oceania
Flooding — Oceania
Oceania's live GloFAS chart appears above, in the tile grid (both the percentile-based "high flow" series and GloFAS's Alert/Warning/Severe return-period tiers). The literature finding below supplies context the live index alone doesn't capture, rather than standing in as a placeholder for it.
The best-supported angle on this site so far (see the dedicated Flooding page): multiple studies document a north/south divergence in Australian flood behavior under warming -- rainfall extremes have intensified in the country's north, while runoff efficiency and flood response have weakened in parts of the south, meaning rainfall trends and flood trends don't move together.

Not Yet Available for Oceania
Listed rather than silently omitted -- these gaps reflect what this site currently breaks out by continent, not a judgment that the phenomenon doesn't matter here.
- Extratropical Cyclone Intensity
- The source catalog (Gray, Volonte, Martinez-Alvarado, Harvey 2024) covers Northern Hemisphere WINTER (Oct-Mar) only -- it carries no genesis or track data near this continent, not just an unbuilt breakdown. See North America/Europe/Asia for the 3 continents this catalog covers.
- Heat Waves / Temperature Extremes
- The underlying GSN station network's density varies widely across continents: Europe and North America both clear a usable bar (see those pages), but Asia (peaks at 121 qualifying stations), Africa (37), South America (33), and Oceania (56) all stay well under 100 at their historical peak, too sparse to say "what changed" rather than "where the stations are."
