I do appreciate your thoughtfulness, Sheilbh.  Anyone who wants to see those pictures can find them on their own.

QuoteThis is Hans, a software engineer at Datawrapper. For this week's edition of the Weekly Chart, I tried to find a personal approach to global temperature increase.

When looking at charts about the increase in global temperature, I sometimes find myself asking: What exactly does that mean for people living now — especially younger generations? These charts often have all the data laid out, but the direct personal relevance is sometimes hard to grasp. Here is my approach:

Methodology
Using the average life expectancy for German citizens in 2017/2019, I calculated the average remaining life expectancy for each age group. Unfortunately, I couldn't find a similar data source for the whole world. The statistical projection for future warming is based on this Guardian article from 2017, which in turn is based on a paper by Raftery et al. from 2017. I chose to use the average of projections, which depicts the most likely scenario.

This chart is heavily inspired by our CTO Gregor's Weekly Chart from two years ago, and uses the same data. Head there if you want to read up on what global temperature increase is and how it affects our future.

Chart choices
The chart above looks like a bar chart — but to create it, I used a Datawrapper scatter plot. It offers the greatest flexibility of all Datawrapper chart types. I mostly used features from the Annotate tab, such as annotation, highlight ranges, and custom lines. To calculate the horizontal "bars," I wrote a tiny script that you can run in the console of your browser. I then pasted the results in the textfield of our "custom lines and areas" feature.


I am, somehow, less interested in the weight and convolutions of Einstein's brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops.

QuoteCentral China: 16 dead in flooded Zhengzhou metro, landslides
President Xi Jinping says situation "extremely severe" after city of Zhengzhou saw a year's worth of rain in just three days

At least 16 people were killed as torrential rain lashed China's central province of Henan, causing landslides and flooding that partially submerged the underground rail system of Zhengzhou.

About 200,000 residents were evacuated as of Wednesday as soldiers led rescue efforts in Zhengzhou – a city of more than 10 million people – where days of rain have inundated the streets and subway, local government officials said.

Images shared on social media on Tuesday showed passengers up to their necks in water and clinging to the handrails inside a carriage on Zhengzhou's subway. Other passengers filmed videos of the water rising in the tunnels outside the carriage windows.

The provincial capital had "experienced a series of rare and heavy rainstorms, causing water to accumulate in Zhengzhou metro", city officials said in a Weibo post on Wednesday.

Twelve people were killed in the Metro, five more were injured and hundreds were rescued, officials said.

"The water reached my chest," a survivor wrote on social media. "I was really scared, but the most terrifying thing was not the water, but the increasingly diminishing air supply in the carriage."

At least four more people were killed in Gongyi city where houses and walls collapsed, the official Xinhua news agency said, adding that rainfall had caused multiple landslides.

Storms have battered Henan province since the weekend in an unusually active rainy season that has caused rivers to burst their banks, flooding the streets of a dozen cities and upending the daily lives of millions of people.

Weather authorities in Zhengzhou, nearly 700km (431 miles) southeast of Beijing, say the rainfall was the highest since record-keeping began 60 years ago with the city seeing the kind of rain it usually gets in a year in just three days.

Some 617.1 millimetres (24.3 inches) of rain fell on Zhengzhou in that time, compared with the city's annual average of 640.8 mm (25.2 inches).

The amount of rainfall was seen only "once in a thousand years", local media cited meteorologists as saying.

"People are shocked, trying to register what is happening," said Al Jazeera's Katrina Yu, who is in Beijing. "This is the most rain that many people have seen in their lifetimes. Many have described the situation as 'terrifying'."

Overnight, authorities warned the deluge had created a 20-metre (66-foot) breach in the Yihetan dam in Luoyang – a city of approximately seven million people – with the risk that it "may collapse at any time".

Soldiers were sent to carry out an emergency response including blasting and flood diversion.

As rain continued to fall on Wednesday, thousands of firefighters and troops were deployed to the region to help with search and rescue, and President Xi Jinping went on state television to demand authorities at all levels give priority to ensuring people's safety, and implement flood prevention and disaster relief measures.

"Some reservoirs had their dams burst ... causing serious injury, loss of life and property damage," the president said on Wednesday. "The flood control situation is extremely severe."

Henan province, home to the Shaolin Temple and many other cultural sites, is one of China's most populous and a major base for both industry and agriculture.

Floods are common during China's rainy season, but the threat has worsened across the decades, due in part to widespread construction of dams and levees.

'Never seen such heavy rainstorm'
Some residents spent the night in their workplaces or hotels.

Wang Guirong, a 56-year-old restaurant manager, said she planned to sleep on the sofa in her restaurant after being told there was no power in her neighbourhood.

"I have lived in Zhengzhou all my life and have never seen such a heavy rainstorm as today," Wang said.

The State Grid Zhengzhou Power Supply Co said it was forced to shutdown a city substation because of the rain.

The flooded subway system was closed, train services suspended and hundreds of flights cancelled.

Schools and hospitals had been cut off by the waters with some children reportedly trapped in their kindergartens since Tuesday.

The First Affiliated Hospital of Zhengzhou, which has more than 7,000 beds, lost all power, and even backup supplies were down, the People's Daily reported.

The hospital was racing to find transfer about 600 critically ill patients to alternative facilities.

Anyone knows of a reliable prediction of how the climate of different regions and countries are likely to change, so I can decide if we should stay on this island, or choose either Poland or Hungary instead? :P I want the kind of climate change where I get to grow oranges, not the kind where I use a boat to get out of my front door.

My default assumption is being near the sea/ocean will have more moderate changes than being inland - until the jet stream stops :ph34r:

Yes....the question is should I be heading north or south.... Where will have British weather in the future? Preferably with a bit more snow.

Just make sure you're at least 10m above sea level.

It's the bit of land where in future you'll be hit by tornadoes, storm surges and regular extreme heatwaves.

The way it's going now, the Scottish highlands would be a safe bet for staying above water level :P

I wouldn't worry about sea level rise on a grand scale too much in most of the UK.
The problem lies more on short term flooding, droughts, etc...
