Tracking Investments in Climate Resilient Infrastructure
The report finds that investments in climate resilient infrastructure (CRI) are in their nascent stages, representing only about 1.1% of average annual infrastructure investment in 2019/20. It proposes a five-principle framework to define and track CRI, though data gaps limited its operationalization to three principles. The study highlights a significant gap between investment and vulnerability, noting no correlation between per capita CRI investment and the ND-GAIN Vulnerability Index. It recommends the adoption of common resilience principles, mandated double materiality disclosures, and the creation of a standardized CRI taxonomy to scale finance.

Climate change exacerbated heavy rainfall leading to large-scale flooding in highly vulnerable communities in West Africa
The 2022 rainy season in West Africa saw above-average rainfall and devastating floods, particularly in Nigeria and Niger, where fatalities reached at least 612 and 195 respectively. An attribution study found that climate change made the seasonal rainfall over the Lake Chad region approximately 80 times more likely and 20% more intense, while the 7-day maximum rainfall over the lower Niger Basin became about twice as likely and 5% more intense. Beyond climate change, the flooding was driven by the release of the Lagdo Dam in Cameroon and exacerbated by high poverty rates, political instability, and the location of infrastructure and settlements on flood plains.

Assessing cascading effects from multiple hazards
The HydroHazards project develops frameworks to analyze how simultaneous or sequential hydrometeorological events impact critical infrastructure and create social vulnerabilities. A national analysis of Sweden indicates that while extreme precipitation, river streamflow, and sea levels rarely coincide in one location, the south and west coasts are more prone to simultaneous floods and extreme sea levels. In the municipality of Halmstad, the project applies a mixed-methods approach—combining network analysis, synthetic distribution networks, and the Impact Chain model—to identify how infrastructure failures lead to cascading effects on the population, distinguishing between underlying social vulnerabilities (e.g., income) and emerging vulnerabilities caused by service disruptions.

SUBMISSIONS ON THE DRAFT NATIONAL WATER RESOURCES STRATEGY-3 PUBLISHED IN GOVERNMENT GAZETTE 47133 ON 29 JULY 2022
The CER's submission on the draft NWRS-3 argues that the strategy must move beyond treating climate change as a future threat and instead implement binding regulations to protect water security. The CER advocates for the formal legal protection of Strategic Water Source Areas (SWSAs), strengthened compliance monitoring and enforcement (CME) through the 'Blue Scorpions', and a moratorium on unconventional oil and gas exploration due to risks of water contamination and methane emissions. It further emphasizes the need for transparency in water licensing and the alignment of the NWRS-3 with South Africa's international commitments under the Paris Agreement and the domestic Climate Change Bill.

Twelve months WWA without Geert Jan
World Weather Attribution (WWA) reports on its activities from October 2021 to October 2022, during which it published eight rapid analyses and several peer-reviewed papers. These studies examined the role of human-induced climate change in events such as heatwaves in India, Pakistan, and the UK, as well as flooding and droughts in various regions. The organization emphasizes that while climate change is a major driver for heatwaves, its role in other events like tropical cyclones can be less clear, often compounding with high levels of vulnerability to increase human impacts.

The Security Implications of the Pakistan Floods
The 2022 floods in Pakistan, which inundated a third of the country, have created a humanitarian catastrophe that exacerbates political instability, provides opportunities for extremist recruitment, and increases risks to nuclear security. The document argues that poor ecological governance and political turbulence worsened the impact. It highlights the potential for groups like the Pakistani Taliban and Islamic State Khorasan to exploit government absence by providing aid. Furthermore, it warns that climate hazards could destabilize nuclear sites or escalate tensions between nuclear-armed neighbors India and Pakistan over water resources in the Indus River Basin. The authors urge the United States to integrate climate considerations into military support and fulfill climate finance commitments to ensure long-term security.

Climate change likely increased extreme monsoon rainfall flooding highly vulnerable communities in Pakistan
The 2022 monsoon rainfall in Pakistan, particularly in Sindh and Balochistan, resulted in catastrophic flooding that affected over 33 million people and caused damages likely exceeding US$30 billion. Attribution analysis indicates that 5-day maximum rainfall in Sindh and Balochistan is now approximately 75% more intense than it would have been without a 1.2C warming, while 60-day rain across the Indus basin is about 50% more intense. While high regional variability and model discrepancies make exact quantification of the human-induced role difficult, most models and observations show that intense rainfall has increased as Pakistan warmed, with future projections suggesting further significant increases in rainfall intensity at 2 °C of warming.

Climate change increased heavy rainfall hitting vulnerable communities in eastern Northeast Brazil
An event attribution study found that human-caused climate change increased the likelihood and intensity of the extreme rainfall that hit eastern Northeast Brazil in May 2022, causing over 133 deaths and displacing at least 25,000 people. While the events were exceptionally rare—with a 1-in-500 to 1-in-1000 annual chance in the current climate—they would have been approximately 20% less intense in a world without human-induced warming. The study highlights that pre-existing structural vulnerabilities, such as unplanned urbanization in low-income neighborhoods and an infrastructure deficit, exacerbated the disaster's impact.

PLEIN NORD : faire face aux coûts des changements climatiques pour les infrastructures du Nord
The report highlights a 'double threat' in Northern Canada: inadequate existing infrastructure and a climate warming three times faster than the global average. Permafrost thaw is causing significant structural damage to runways, roads, and residential buildings, which threatens essential services like healthcare and food security. The authors argue that while incremental adaptation (e.g., thermosiphons) can delay costs, 'transformational adaptation'—repensuring how services are delivered and where infrastructure is located—is necessary to address systemic deficits rooted in colonial history. The report recommends federal funding restructuring, improved regional climate risk data, and updated building codes to ensure long-term resilience.

Climate change increased rainfall associated with tropical cyclones hitting highly vulnerable communities in Madagascar, Mozambique, Malawi
A collaborative scientific analysis concludes that greenhouse gas and aerosol emissions contributed to the increased likelihood and intensity of heavy rainfall during Tropical Storm Ana and Tropical Cyclone Batsirai in early 2022. While Tropical Storm Ana was a rare event for Malawi and Mozambique (1 in 50 years), Cyclone Batsirai was more common for Madagascar (1 in 2 years). The study highlights that existing vulnerabilities, including prior flooding, conflict in northern Mozambique, and drought in southern Madagascar, exacerbated the humanitarian impacts.
