Fires in summer, mud rivers in autumn and heat records in winter.

The province of British Columbia in Canada is suffering from increasingly extreme weather.

- These types of extremes have become more common in many places. In British Columbia in particular, they had an emergency a few weeks ago because there were such large floods, says climate professor Erik Kjellström at SMHI.

 

In the city of Penticton in British Columbia , it has been 22.5 degrees hot. It's the hottest December day in Canada since 1982, according to CBC .

The third storm in a short time has just passed. It caused mudslides and heavy rain. In November, the parents of a 2-year-old girl and two other people died .

Several roads are still closed. Now the snow is melting due to the heat and creating concern about new floods.

 

Worse heat is becoming more common

This summer, several cities in Canada broke heat records. Drought and about 300 forest fires raged in British Columbia.

- It is not surprising in any way. Breaking hot records is more expected than calling cold records. The extreme heat of the summer in Canada is more or less impossible that it could have happened if people had not changed the climate, says Erik Kjellström.

Authorities classified the heat as "life-threatening" and 486 people died in five days , compared to the normal level of 165, according to the BBC.

 

Erik Kjellström believes that extreme heat is becoming more common with global warming. At the same time, cold extremes are becoming more unusual.

- It is very clear. The atmosphere is getting warmer. It evaporates more water from land and oceans which then comes down from the atmosphere. Precipitation amounts are also increasing, he says.

 

The increased evaporation in turn leads to more drought.

- In the Mediterranean region, among other places, we have seen an increase in dry extremes.

More extreme in Sweden with

Sweden may be affected by similar weather - even if temperatures will not be as high.

There will be warmer and greater contrasts between dry and wet.

- But in principle, of course. We have the year 2018 as an example. March was a high-pressure-dominated month, it was quite cold in Sweden then. Then came a high pressure in May. It got really hot and we had big forest fires that caused a lot of problems, says Erik Kjellström.

Exact quantities and values of temperatures differ, of course. Vancouver is more like the climate in the Norwegian mountains with large amounts of precipitation. The mountain ranges capture the air and force them to be lifted, which makes it rain.

How they roll, and try to blame Biden for high prices B)

The fossil fuel industry experienced a boom in profits during the first nine months of 2021, raking in tens of billions of dollars as Americans faced a jump in gas prices.

A new report by Accountable.US shows that 24 top oil and gas companies made $174 billion in profits between January and September, lining shareholders’ and CEOs’ pockets. Sixteen of those companies raised their dividend at least once in 2021, the report found, and most of their CEOs had compensation packages of over $10 million.

Companies like Exxon and Chevron have posted high profits in the third quarter of 2021; in just four months, the 24 companies made $74 billion in profits. Exxon alone reported making $6.9 billion in the third quarter, a 60 percent increase in revenue from the same time last year and its highest profits for four years.

From the beeb, as the UN could be about to announce a climate crisis in Madagascar 

A prolonged drought in the deep south of the island has left 1.3 million people struggling to find food and 28,000 facing starvation. Some have called it the world's first famine caused by climate change, though this has been disputed.

A prolonged drought in the deep south of the island has left 1.3 million people struggling to find food and 28,000 facing starvation. Some have called it the world's first famine caused by climate change, though this has been disputed.

 

This is little to do with climate change and all to do with deforestation. 

Slash and burn farming has for centuries been practised on the island; it's estimated that about 80% of the island's original forest has gone. Around 40% of the forested areas were lost in just 50 years between 1950 - 2000 and a further 25% of the remaining forest has been lost since then. The loss of tree cover has lead to loss of soil moisture due to increased sun exposure, stunted growth of the remaining understorey plants and eventually soil erosion. One of the biggest lakes in Madagascar which provides water for irrigation via mini canals has decreased in size by 30% in the last 40 years due to build up of sediment from the destroyed forests. The water quality of the lake has also suffered, severely hitting rice production. It's then a vicious circle, little vegetation cover to stabilise the soil, more sediment ending up in waterways (estimated at 400 tonnes per hectare annually), poorer water quality, thinner soils lacking humus due to minimal leaf litter recycling leading to stunted growth, even less vegetation cover , etc etc. 

Couple this massive reduction in crop yields (particularly rice) with another drought - the South is semi-desert and often experiences them - then add a rapidly rising population, growing from about 6.5 million in 1970 to nearly 28 million today and you have conditions ripe for famine. Tragically they are suffering mainly due to the consequences of their own actions.
