This year, extreme floods, droughts, fires and storms related to climate change have cost thousands and billions of euros, the report said.
Among the most expensive disasters in the world this year were Hurricanes Florence and Michael, which struck parts of the US, Central America and the Caribbean, according to a Christian Aid report.
There were also heat waves and droughts in Europe, where record temperatures in the UK were 30 times more likely to be caused by climate change, according to the British Met Office, causing fires and falling prices.
In Kerala, India, the worst flooding in more than 80 years, Japan had an extreme summer, and fires in California, including Camp Fire, which was the deadliest in the state.
Experts warn that unprecedented extremes are "the face of climate change" and called for a rapid reduction in carbon emissions to avoid more destructive weather.
Christian Aid's report, Counting Costs: The Year of the Climate Disaster, lists the 10 most devastating droughts, floods, fires, typhoons and hurricanes in 2018, all of which said it caused more than $ 1 billion (878 million euros) in damage. .
All the billion-dollar disasters are linked to human-caused climate change, the report argues.
In some cases, scientific studies have shown that climate change has made a particular event more likely or more powerful, such as hurricane Florence and the heat of Europe.
In other cases this is caused by changes in weather patterns, such as higher temperatures and reduced rainfall.
While the report focuses on the extreme financial cost of the weather, it also warns of the cost of living, and living conditions are even higher.
Disaster factors include Hurricane Florence, worth US $ 17 billion (EUR 14.4 million) and Hurricane Michael, which cost US $ 15 billion (EUR 16.6 million).
Europe's summer drought was estimated to be worth $ 7.5 billion (€ 6.66 million), while there were also significant droughts in Argentina, Australia and Cape Town, South Africa.
Japan suffered a flood that killed at least 230 people and cost $ 7 billion ($ 5.55 million), followed by record-breaking fever and typhoon fever.
Typhoon Mangkhut has hit the Philippines and China, floods have killed more than 500 people and forced millions from their homes in Kerala, India, and fires have hit California.
Dr Kat Kramer, Global Climate Management at Christian Aid, said: "Climate change is often talked about as a future problem, especially since we know that the effects of warming climate are so devastating and we don't want to deal with it. It is already happening.
"This report shows that for many people, climate change has now had a devastating impact on their lives and livelihoods.
"We must respond to the disasters that these disasters give us and prevent more and more disasters by speeding up the transition to a zero-carbon economy: a clean and renewable energy carrier that will deliver a safer climate for everyone."
Dr. Michael Mann, of Penn State University in the US, said: "The impacts of climate change are no longer subtle.
"We see them playing on our television screens, newspaper headlines and social media now.
"The unprecedented floods, droughts, heat waves, fires and prejudices we have seen in recent years – they are the face of climate change.
"The weather in the world is becoming more extreme in front of us – the only thing that can stop this destructive trend from escalating is the rapid decline in carbon emissions."
