Climate change: Huge costs of warming impacts in 2018

Extreme weather events linked to climate change cost thousands of lives and caused huge damage throughout the world in 2018, say Christian Aid. The charity's report identified ten events that cost more than $1bn each, with four costing more than $7bn each.

Scientists have shown that the chances of heat waves in Europe were influenced directly by human-related warming. Other events, say the authors, are due to shifts in weather patterns, said to be a consequence of climate change.

According to the report the most financially costly disasters linked to rising temperatures were Hurricanes Florence and Michael, with costs said to be around $17bn for the former, and $15bn for the latter. Research published at the time showed that the rains accompanying Hurricane Florence were made 50% worse than they would have been without human influenced warming. With Hurricane Michael, experts say that human activities drove the emissions that made the water warmer, adding fuel and speed to the storm.

In Japan, 2018 was the summer of extremes with flooding and heatwaves causing huge impacts. The floods killed at least 230 people and caused $7bn worth of damage, which were then followed by Typhoon Jebi, the most powerful storm to hit the country for 25 years.

Europe also saw record heatwaves - with researchers showing that climate change likely doubled the chances of the events happening.

The Christian Aid study says even where scientists have not done attribution studies linking events to climate change, they believe that warming is driving shifts in weather patterns that make droughts and wildfires more likely.

Commenting on the Christian Aid report, Dr Michael Mann from Penn State University said the impacts of climate change were no longer subtle. "The unprecedented floods, droughts, heat waves, wildfires and super storms we've seen in recent years - they are the face of climate change. The world's weather is becoming more extreme before our eyes - the only thing that can stop this destructive trend from escalating is a rapid fall in carbon emissions."

According to the World Meteorological Organisation's initial observations, 2018 is likely to be the fourth warmest on record with the Earth's average temperature hovering close to 1C above the levels recorded in 1850-1900.
