What this story says
- Ho Chi Minh City faces a growing flood risk due to the combination of high tides, heavy rain, climate change, rapid urbanisation, and land subsidence.
- On September 30, heavy rain and high tide caused rivers and smaller waterways to overflow onto city roads.
- Nearly half of the city's land is less than one metre above sea level, making it vulnerable to inundation.
- The city has initiated a $13 billion plan to address 159 flood-prone areas by 2030.

Missing from the right
Only 1 of the 14 outlets with a published leaning rating that ran this story are rated right.
A reader who follows the right would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.
Forecasters issued warnings on September 27 that high tides, combined with heavy rainfall, could elevate flood risks in Ho Chi Minh City. The city experienced this prediction on the evening of September 30 when substantial rain and a high tide caused the Saigon River and other waterways to breach their banks, flooding streets. This event highlights the city's vulnerability, with almost half of its landmass situated less than one metre above sea level.
Benjamin Horton, a professor of earth science at City University of Hong Kong, stated that climate change intensifies flood risks by interacting with rapid urbanisation and land subsidence. He explained that a warming climate leads to rising sea levels and more intense downpours, which can overwhelm drainage systems, particularly in densely populated areas. Groundwater extraction further contributes to the problem by causing the ground to sink. These factors increase the likelihood of homes and businesses being inundated, disrupting transport, damaging infrastructure, and posing public health risks.
In response to these challenges, Ho Chi Minh City launched a $13 billion plan in July aimed at mitigating flooding in 159 identified hotspots by 2030. The city also adopted a climate action plan through 2030 to upgrade drainage systems, expand green spaces, and improve its resilience to extreme weather events. Horton noted that rising sea levels impede drainage, while heavier rainfall increases the volume of water entering the city quickly. In a sinking city, water accumulates and recedes more slowly, leading to more frequent, deeper, and longer-lasting floods.
Coverage comparison
What the coverage left out
None of the left-rated or centre-rated reports mentioned the specific date of July when the city launched its $13 billion flood mitigation plan. The digests from Biz Toc, St Catharines Standard, The Seattle Times, The Independent, and The Independent (US) did not provide specific details on the flood mitigation plan's timeline or the city's climate action plan.
Coverage settled. We checked this 9 times and stopped on 6 Oct 2026, 18:45. The figures above are what it finished at.
How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
9 rated outlets
- The left-rated reports focused on the confluence of factors contributing to Ho Chi Minh City's flood risk. They highlighted warnings issued on September 27 about high tides and heavy rain, and the subsequent flooding on September 30. These reports included details about the city's low elevation, with nearly half of its land less than one metre above sea level. The role of climate change, amplified by rapid urbanisation and land subsidence, was a central theme, with quotes from Benjamin Horton, a professor of earth science. The $13 billion flood mitigation plan and the city's climate action plan were also noted. The reports described residents adapting to the floods, with some raising their homes and street vendors continuing to operate.
Centre
4 rated outlets
- The centre outlets reported that Ho Chi Minh City regularly experiences flooding and that climate change has increased the risk. Washington Top News and My Mother Lode noted forecasters warned on 27 September that high tides combined with heavy rain could raise flood danger, describing the city as among the world’s most climate‑vulnerable locations.
- Cedarnews.net focused on the immediate impact after the rain on 1 October, reporting that more than fifteen hours later hundreds of households in Thu Duc ward remained under water up to half a metre deep, disrupting daily life for residents.
- None of the centre digests included a monetary estimate for flood mitigation, quoted city officials, or described specific adaptation projects. They also omitted any reference to insurance claims or international assistance, leaving those aspects unaddressed in the presented material.

Questions about this coverage
- How did the left and right cover Ho Chi Minh City faces rising flood risk from climate change?
- Of the 14 outlets on this story carrying a published leaning rating, 64% are rated left, 29% are rated centre, 7% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 20. The sections above set out what each side emphasised, in its own terms.
- Is Ho Chi Minh City faces rising flood risk from climate change left or right?
- Neither side dominates it. Of the 14 rated outlets on this story, 64% are rated left, 29% are rated centre, 7% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Ho Chi Minh City faces rising flood risk from climate change biased?
- Ho Chi Minh City faces rising flood risk from climate change is one event reported by 20 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Ho Chi Minh City faces rising flood risk from climate change?
- When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Ho Chi Minh City faces rising flood risk from climate change?
- 20 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- What caused the flooding in Ho Chi Minh City on September 30?
- On the evening of September 30, heavy rain combined with a high tide caused the Saigon River and smaller waterways to overflow onto the city's roads. Forecasters had warned on September 27 that these conditions could increase flood risk.
- Why is Ho Chi Minh City particularly vulnerable to flooding?
- Nearly half of Ho Chi Minh City's land is less than one metre above sea level. This low elevation, combined with rapid urbanisation, land subsidence, and the impacts of climate change such as rising sea levels and heavier rainfall, significantly increases its flood vulnerability.
- What is Ho Chi Minh City doing to address flooding?
- The city has launched a $13 billion plan to tackle 159 flood hotspots by 2030. It has also adopted a climate action plan through 2030 to upgrade drainage systems, expand green spaces, and improve its ability to cope with heavy rain, high tides, and rising sea levels.
