Case studies of past severe weather events. These are external links and will open in a new window With extreme weather events on the rise, we look at the difference between weather and climate. “The 1% stress test is not as extreme as it might sound – it implies a 10% chance of an organization being affected once a decade,” they say. https://bbc.in/30qtzkW. The authors want organisations to report their maximum probable losses due to extreme events, based on a 1% chance of the event on any given year. But they argue that governments will also need to adapt to future climatic shifts driven by climate change.They suggest threats could be tackled through a dual approach. Much of North America is in an icy grip at the moment, including Carol Kirkwood learns about a citizen science experiment inviting people to record the temperature where they are and describe how they cope in the heat.Temperatures are forecast to top 30C in some parts of the UK this weekend. It assumes a population of nine billion. The UK is comparatively resilient to extreme events - but vulnerable because of high population density These storms and weather events are some of the worst we’ve seen, as well as some of the craziest. “For most hazards, population increase contributes at least as much as climate change - sometimes more. As well as building homes insulated against the cold, we must also ensure they can be properly ventilated in the summer, the report says.The authors say cutting greenhouse gas emissions is essential. Storm Jorge New 28 February to 1 March 2020 Storm Jorge brought further strong winds and heavy rain in late-February. Weather Videos. Jump to a year: 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1998 1990. Check. BBC News. The simplest and cheapest way of tempering heatwaves, they say, is to maintain existing green space. BBC News. “It is impossible for us to avoid the worst and most unexpected events. They say decisions made over the next few decades as the world builds vast urban areas will be key to the resilience of people by the end of the century.The California senator is the first black woman to be chosen as a running mate. We must organise ourselves right away. BBC Weather's Helen Willetts looks at some of the main weather stories around the world.
The authors say air conditioners are the most effective way of keeping cool – but they are costly, they dump heat into city streets and their use exacerbates climate change.Flooding is another priority area, the report says.
It finds that large-scale engineering solutions like sea walls offer the most effective protection to coastal flooding - but they are expensive, and when they fail the results can be disastrous.The ideal solution, the authors think, may be a combination of “hard” engineering solutions like dykes matched with “soft” solutions like protecting wetlands to hold water and allow it to seep into the ground. Some areas may experience many weeks when outdoor activity is heavily restricted, they fear – although the trend of agricultural labour loss may be offset through the century as more and more people move to cities.It puts a figure on those at greatest overall risk: populations in poor countries make up only 11% of those exposed to hazards but account for 53% of the disaster deaths. Extreme weather can be the 'most important cause of poverty' Urbanisation creates heat islands which can exacerbate the effects of hot weather Today at 6:17 PM. They warn that the effects of extremes will be exacerbated by the increase in elderly people, who are least able to cope with hot weather. They say: “Unless risks are accurately evaluated and reported, companies will have limited incentives to reduce them. The report says governments have not grasped the risk of booming populations in coastal cities These are external links and will open in a new windowClimate change and population growth will hugely increase the risk to people from extreme weather, a report says.The Royal Society warns that the risk of heatwaves to an ageing population will rise about ten-fold by 2090 if greenhouse gases continue to rise.They estimate the risk to individuals from floods will rise more than four-fold and the drought risk will treble.The report’s lead author Prof Georgina Mace said: “This problem is not just about to come… it’s here already." They say they have built upon earlier work by calculating the effects of climate change coupled with population trends. Today at 7:18 PM. Some economists argue this shows that poor nations should increase their economies by burning cheap fossil fuels because that will allow them to spend more later on disaster protection.The authors also call for reform of the financial system to take into account the exposure of assets to extreme events. Media requires JavaScript to play. We are making ourselves more vulnerable whilst making the climate more extreme. Urbanisation will make the issue worse by creating “heat islands” where roads and buildings absorb heat from the sun.
