Five key ways to confront climate change in 2025
The World Weather Attribution highlighted five key ways to confront climate change in 2025; namely ...
Climate change caused deaths of about 3,700 people, displacement of millions in 2024
Climate change contributed to the deaths of at least 3,700 people and the displacement of millions in 26 weather events in 2024, according to World Weather Attribution.
It’s likely the total number of people killed in extreme weather events intensified by climate change this year is in the tens, or hundreds of thousands.
Globally, climate change added on average 41 additional days of dangerous heat in 2024 that threatened people’s health, according to new analysis by Climate Central.
The countries that experienced the highest number of dangerous heat days are overwhelmingly small island and developing states, who are highly vulnerable and considered to be on the frontlines of climate change. The analysis highlights the wide reaching impacts of extreme heat that are underreported and not well understood.
Many extreme events that took place in the beginning of 2024 were influenced by El Niño. However, most of the organization’s studies found that climate change played a bigger role than El Niño in fueling these events, including the historic drought in the Amazon. This is consistent with the fact that, as the planet warms, the influence of climate change increasingly overrides other natural phenomena affecting the weather.
Record-breaking global temperatures in 2024 translated to record-breaking downpours. From Kathmandu, to Dubai, to Rio Grande do Sul, to the Southern Appalachians, the last 12 months have been marked by a large number of devastating floods. Of the 16 floods which the World Weather Attribution studied, 15 were driven by climate change-amplified rainfall.
The result reflects the basic physics of climate change — a warmer atmosphere tends to hold more moisture, leading to heavier downpours. Shortfalls in early warning and evacuation plans likely contributed to huge death tolls, while floods in Sudan and Brazil highlighted the importance of maintaining and upgrading flood defenses.
The Amazon rainforest and Pantanal Wetland were hit hard by climate change in 2024, with severe droughts and wildfires leading to huge biodiversity loss. The Amazon is the world’s most important land-based carbon sink, making it crucial for the stability of the global climate. Ending deforestation will protect both ecosystems from drought and wildfire, as dense vegetation is able to absorb and retain moisture.
Hot seas and warmer air fueled more destructive storms, including Hurricane Helene and Typhoon Gaemi. Individual attribution studies have shown how these storms have stronger winds and are dropping more rain. Research by Climate Central found that climate change increased the intensity of most Atlantic hurricanes between 2019 and 2023 – of the 38 hurricanes analyzed, 30 had wind speeds that were one category higher on the Saffir-Simpson scale than they would have been without human-caused warming, while the organization’s analysis found that the risk of multiple Category 3-5 typhoons hitting the Philippines in a given year is increasing as the climate warms.
The organization highlighted that extreme weather reached dangerous new heights in 2024. This year’s record-breaking temperatures fueled unrelenting heatwaves, drought, wildfire, storms and floods that killed thousands of people and forced millions from their homes. This exceptional year of extreme weather shows how dangerous life has already become with 1.3°C of human-induced warming, and highlights the urgency of moving away from planet-heating fossil fuels as quickly as possible.
