In this study, a series of numerical analyses of meteorology, runoff, river flow, and inundation were performed to quantitatively evaluate the effects of historical warming on precipitation, discharge, water level, and flood inundation. This study was on the flood inundation of the Chikuma River Basin in Japan caused by Typhoon Hagibis in 2019. The hist…
Climate change has already made extreme precipitation in California twice as likely, part of a trend projected to continue through 2100. Extreme storm sequences are projected to generate 200% to 400% more runoff by the end of the century. Today’s study is the first part of ArkStorm 2.0, a scenario to prepare for catastrophic flooding in the western…
This study provides perspective on projected future changes in extreme ocean waves by quantifying change in high-frequency extreme wave events over decision or impact-relevant time horizons using a multi-index approach and a large multi-method multi-model ensemble. The projected increases in high-frequency extreme wave forcing across most of the Souther…
This article aims to establish a rainfall-runoff relationship; estimate depth and extent of inundation under climate change scenarios; assess impacts on the socio-economy; and identify and evaluate adaptation strategies in Nepal's East Rapti Watershed (ERW). The ERW has been the site of devastating floods but effective mitigation and adaptation measures…

Pakistan is experiencing the most devastating and widespread floods in its history, with the country’s climate minister saying waters have reached across a third of the nation. The growing tally of impacts is dire. More than 1,100 people have been killed, a million homes have been destroyed and 33 million people have been directly a…

Massive monsoon flooding has followed a severe drought in Pakistan’s Sindh province, with experts saying that climate change is making farming ‘more challenging every passing day’. The majority of Pakistan’s second-most populous and agriculture-dependent province of Sindh was declared “calamity-hit” on 23 August. With torrential monsoon rain…
From January to April 2015, Mozambique experienced prolonged heavy rain, which contributed to the rising of water levels in the Zambezi, Licungo and Shire River basins, exposing the population to flooding. Factors which contributed to the high level of flooding are: (i) heavy rainfall; (ii) flat terrain; (iii) high tide; and (iv) inappropriate drainage…
The St. Lawrence riverbanks are eroding. This has an impact on infrastructure, economy and inhabitants’ well-being. It exposes communities to flooding and can destroy local ecosystems. Under the threat of a climate catastrophe, an in-depth reflection is essential to adapt to the changing climate in the St. Lawrence. In Prince Edward Island, the a…
Climate change is destroying heritage sites across Europe and globally. Ancient historical landmarks could disappear completely unless swift action is taken to protect them from environmental damage, researchers are warning. Future generations may never get to explore streets conquered by medieval knights in Greece, city quarters built by the Islamic e…

Europe: floods July 2021

Extreme rainfall occurred in Germany, Belgium, Luxembourg and neighbouring countries during the period 12 to 15 July 2021, leading to severe flooding particularly in North Rhine-Westphalia and Rhineland-Palatinate in Germany and along the river Meuse and some of its tributaries in Belgium and the Netherlands. The most affected areas are around the river…
This paper draws upon recent research in Ba Town to examine the drivers, patterns, and impacts of internal displacement linked with disasters. Disasters have triggered around 153,000 displacements in Fiji, since IDMC started systematically collecting data in 2008. Rapid urbanisation, particularly the growth of informal settlements, is increasing ex…
Climate change and environmental degradation have a range of implications, both direct and indirect, for the effective enjoyment of human rights. In 2021 the UN Human Rights Council (UNHRC) recognised that access to a clean, healthy and sustainable environment is a human right, which was confirmed by the UN General Assembly on the 28th July 2022. The w…
This research investigates if, and to what extent, there are social inequalities in climate change-attributed extreme weather event impacts. Here, the researchers use climate change attribution science paired with hydrological flood models to estimate climate change-attributed flood depths and damages during Hurricane Harvey in Harris County, Texas. Usi…

Climate change is here to stay, bringing with it changing weather patterns. According to current models, the northeastern United States can expect an increase in extreme rainfall events. The remnant of Hurricane Ida that hit New York City in the summer of 2021, dropping more than seven inches of rain in less than 24 hours and flooding the subway system,…
In August, the world looked on aghast as torrential rains and flash flooding submerged vast areas of Pakistan, affecting 33 million people, killing more than 1,300 and destroying or badly damaging 1.6m homes. The floods hit during the south Asian monsoon, which typically brings seasonal rains to the Indian subcontinent between June…
