Mainstreaming our changing climate – attribution

Image result for car dice“The media, politicians and some scientists outside the area of single event attribution research still often claim that “we can’t attribute any individual event to climate change.” This may have been true in the 1990’s, but it is no longer the case…..People do not necessarily make the connections that have been shown by scientific analysis to exist between extreme weather and climate change.

If people had help connecting the dots – that is, if scientific linkages were clearly articulated and reported more often and more accurately in the media – perhaps the effect of extreme weather on peoples’ views would be greater, leading to better planning to adapt to changes, improved behavioural change, and more action on climate change.” Access full WMO article here

Mapped: How climate change affects extreme weather around the world

15 April 2020, Carbon Brief: In the early 2000s, a new field of climate-science research emerged that began to explore the human fingerprint on extreme weather, such as floods, heatwaves, droughts and storms. Known as “extreme event attribution”, the field has gained momentum, not only in the science world, but also in the media and public imagination. These studies have the power to link the seemingly abstract concept of climate change with personal and tangible experiences of the weather. Scientists have published more than 300 peer-reviewed studies looking at weather extremes around the world, from wildfires in Alaska (pdf) and hurricanes in the Caribbean to flooding in France and heatwaves in China. The result is mounting evidence that human activity is raising the risk of some types of extreme weather, especially those linked to heat. To access map and to read more here

Using the map: The map shows 355 extreme weather events and trends across the globe for which scientists have carried out attribution studies. The different symbols show the type of extreme weather; for example, a heatwave, flood or drought. The colours indicate whether the attribution study found a link to human-caused climate change (red), no link (blue) or was inconclusive (grey).

International Meeting on Statistical Climatology

6 July, RealClimate: The heatwave took place and was an appropriate frame for the International meeting on statistical climatology (IMSC), which took place in Toulouse, France (June 24-28). France set a new record-high temperature 45.9°C on June 28th, beating the previous record 44.1°C from 2003 by a wide margin (1.8°C). One of the topics of this meeting was indeed heatwaves and one buzzword was “event attribution”. It is still difficult to say whether a single event is more likely as a result of climate change because of model inaccuracies when it comes to local and regional details. Weather and climate events tend to be limited geographically and involve very local processes. Climate models, however, tend to be designed to reproduce more large-scale features, and their output is not exactly the same as observed quantity. Hence, there is often a need for downscaling global climate model results in order to explain such events. A popular strategy for studying attribution of events is to run two sets of simulations: ‘factual’ (with greenhouse gas forcing) and ‘counterfactual’ (without greenhouse gas forcings) runs for the past, and then compare the results. Another question is how to “frame” the event, as different definitions of an event can give different indicators. Individual heatwaves are still difficult to attribute to global warming because soil moisture may be affected by irrigation wheras land surface changes and pollution (aerosols) can shift the temperature. These factors are tricky when it comes to modeling and thus have an effect on the precision of the analysis. Nevertheless, there is little doubt that the emerging pattern of more extremes that we see is a result of the ongoing global warming. Indeed, the results presented at the IMSC provide further support for the link between climate change and extremes (see previous post absence of evidence). Read more here

18 March 2016, Pursuit (Melbourne Uni) Australia is at the forefront of research in the rapidly developing science of “Event Attribution”  Whenever we experience heatwaves or cold snaps, droughts or floods, people want to know: was this due to climate change? And until about a decade ago the response was: we don’t know. We can’t link specific extreme weather events to climate change. Now things have changed. While we can’t say climate change caused an extreme event, we can estimate how much more or less likely the event has become due to human influences on the climate. This relatively new and rapidly developing area of science is called “Event Attribution” and it was the subject of a recent US National Academy of Science report . The report finds that event attribution allows us to quantify the role that humans have had on some specific extremes. But, it also challenges scientists to better evaluate our methods and communicate the results we get. Read More here

‘If Europe’s ports are underwater, Brexit may seem less important’: we’re expanding climate change coverage

From 3 October The World Tonight on BBC Radio 4 and Newshour on BBC World Service will be covering climate change every week. The BBC’s been reporting for a long time that climate change is not some distant issue whose effects that will only be felt by our grandchildren. Temperature rises are affecting crops, changing the rainforests, and putting massive amounts of extra energy into the world’s weather systems. Rising temperatures are pushing malaria into parts of Africa that have never had the disease. The increased carbon dioxide in the atmosphere has made the oceans more acidic, so much so that we can actually observe the shells of tiny snails being dissolved by the water, threatening the entire marine food chain. While the BBC has been consistently covering all of this, and investing heavily in specialist correspondents, climate change doesn’t always get the attention it deserves. One reason for this is the way daily news programmes tend to work. We’re very good at covering the events of the day. The problem, which all editors and news organisations face, is that some of the most important things happening in the world aren’t always events. They’re often a process, a trend, a gradual change. They don’t always compete well against daily news events that feel more urgent – explosions, elections, Presidential tweets.So to make sure climate change doesn’t get crowded out, we’re committing ourselves and our programmes to covering it at least once week. However, we’re not intending to give you a weekly update on Doomsday. Mitigating climate change, and adapting to the consequences of what we’ve already done to the atmosphere, is driving huge changes in technology, business, and increasingly, politics. Our first edition will come from Norway, a country that’s grown rich on fossil fuels, but now hoping to become Europe’s renewable energy “battery.” Read more here

Weather presenters in US increasingly including climate info in reports

Local US weather casters have become one of the primary conduits for news on global warming. One nonprofit helped push the change. Steve LaPointe has been a television weatherman for nearly three decades, and for most of his career, he didn’t focus much on global warming. He was skeptical about the science behind it, particularly the notion that human behavior was heating the planet. But the issue wouldn’t go away. So LaPointe began to do “a lot of homework,” he said, reading research papers and consulting fellow meteorologists, who connected him with a nonprofit, Climate Central, that spreads information on climate change. LaPointe increasingly came to realize he was wrong — that the evidence that greenhouse gases are warming the Earth is “irrefutable.” Now, LaPointe routinely reports on the effects of climate change — from the escalated growth of poison ivy to a jump in the number of high-pollen days — alongside his usual seven-day nightly forecasts on CBS affiliate WRGB in Albany, New York. Many other weather presenters are following. Read more here  Here are some examples

World Weather Attribution

World Weather Attribution is an international effort designed to sharpen and accelerate the scientific community’s ability to analyze and communicate the possible influence of climate change on extreme-weather events such as storms, floods, heat waves and droughts. Recognizing society’s interest in reducing the human, economic, and environmental costs of weather-related disasters, WWA delivers timely and reliable information on how patterns of extreme weather may be affected by climate change.

The program — a partnership of Climate Central, the University of Oxford Environmental Change Institute (Oxford ECI), the Royal Netherlands Meteorological Institute (KNMI), the University of Melbourne, and the Red Cross Red Crescent Climate Centre (the Climate Centre) — was initiated in late 2014 after discussions within the scientific community concluded that the emerging science of extreme-event attribution could be operationalized. Climate Central coordinates the program and provides its secretariat.

6 July 2017, Carbon Brief, Mapped: How climate change affects extreme weather around the world. In the early 2000s, a new field of climate science research emerged that began to explore the human fingerprint on extreme weather, such as floods, heatwaves, droughts and storms. Known as “extreme event attribution”, the field has gained momentum, not only in the science world, but also in the media and public imagination because of the power it has to link the seemingly abstract concept of climate change with our own tangible experiences of the weather. Scientists have published more than 140 studies looking at weather events around the world, from Typhoon Haiyan to the California drought. The result is mounting evidence that human activity is raising the risk of some types of extreme weather, especially those linked to heat. Carbon Brief’s analysis suggests 63% of all extreme weather events studied to date were made more likely or more severe by human-caused climate change. Heatwaves account for nearly half of such events (46%), droughts make up 21% and heavy rainfall or floods account for 14%. To track how the evidence on this fast-moving topic is stacking up, Carbon Brief has mapped – to the best of our knowledge – every extreme event attribution study published in a peer-reviewed journal. Our aim is to update the map periodically, as new studies are published, so that it serves as a real-time tracker for the evolving field of “extreme event attribution”. Using the map The map above shows 144 extreme weather events across the globe for which scientists have carried out attribution studies. The different symbols show the type of extreme weather; for example, a heatwave, flood or drought. The colours tell you whether or not the attribution study found climate change had played a role in that event (see the key on the right-hand side). Read More here

Climate Central

CLIMATE CENTRAL communicate the science and effects of climate change to the public and decision-makers. It is an independent organization of leading scientists and journalists researching and reporting the facts about our changing climate and its impact on the public. Climate Central surveys and conducts scientific research on climate change and informs the public of key findings. Climate Central is not an advocacy organization. We do not lobby, and we do not support any specific legislation, policy or bill. 

Climate Science

CLIMATE SCIENCE: Climate Central is a leading authority on climate science. Their science team cuts through the hype with clear-eyed analysis of climate change, delivering just the facts and findings. They dig deep into the the data to produce reports on climate trends and impacts, from state level temperature trends, to wildfires, heat waves, drought, precipitation and more. Their reports make climate change interesting and meaningful to people where they live, and provide policy-makers with objective, relevant facts on the issue. 

Key project areas cover: Research; Surging Seas; Attribution; States at Risk 
EXAMPLE – CLIMATE SCIENCE: The WWA team and colleagues from the University of New South Wales conducted a rapid attribution analysis to see how climate change factored into the exceptionally warm summer (December to February) of 2016-2017. The team also looked at the hottest three-day average February temperatures in Canberra and Sydney. Access full article here

Climate Matters

CLIMATE MATTERS: Research shows that meteorologists are trusted messengers on climate change. The majority understand that climate change is real and that the science of climate change needs to be communicated to the public. Unlike climate scientists, TV meteorologists have unparalleled access to their communities. Through Climate Matters, Climate Central provides regularly produced content on the relationship between weather and climate.

Our team of data analysts, meteorologists, climate experts, graphic artists and journalists create graphics, text, animations, videos and research to aid TV weather casters in presenting science-rooted climate information in clear, concise and relevant ways. Each week, we create high-quality information and graphics for our partner meteorologists including:

  • Localized data and analyses that show the ways that the climate is changing in their markets
  • TV-ready graphics and multimedia content for use across all platforms – including maps, interactive tools, severe weather trackers, temperature trend charts– that convey climate change powerfully and accessibly to general audiences
  • Extreme weather analyses produced in the news cycle so that weather casters have reliable climate data as storms are happening—and when millions of people are paying attention


Since 2012, Climate Central’s program has grown to include more than 300 local TV meteorologists who routinely reach millions of viewers. The success of Climate Matters led to a partnership with Weather Company subsidiary WSI, which distributes our analyses to the majority of the nation’s TV weather forecasters.

World Weather Attribution: WWA applies a unique scientific approach that combines observational data, analysis of a range of models, peer-reviewed research, and on-the-ground reports. WWA uses the following criteria to decide which extreme weather events are candidates for a rapid, near real-time analysis by the partner organizations.
  • The event has major impacts on people
  • Enough usable data is available to understand what happened in terms of the meteorology in order to define the event, and there’s enough historical observations to put the event in context.
  • There is output of a model in principle capable of describing the event.
