It is hot in Europe & will potentially be extremely hot. These temperatures would have been lower if it wasn't for our burning of fossil fuels. This also means fewer people would have died. Heatwaves are by far the deadliest extremes in Europe (this includes the UK!)

It has been hot over India and the heatwave is forecast to continue, with severe impacts. A heatwave that would have been rare without climate change but is, like heatwaves around the world, much more common now & will become more & more so as long as we burn fossil fuels.

Iβm very happy my quotes at the bottom made it in the article. This is why attribution matters. Climate change made Australiaβs devastating fire season 30% more likely
Climate change, not the strong El Nino is the real game changer in driving the exceptional drought in Amazon river basin - home of the the largest rainforest in the world. New & worrying

Whether it'll be 40C next week or we'll break that record in one of the coming summers is irrelevant. Fact is, 40C is what we now need to be prepared for, thanks to burning fossil fuels. We're not prepared yet & many people will die, whether it'll be 40 or 37C.

@WWAttribution
study of a heatwave you probably have never heard of. Extreme heat in subsaharan Africa - made by burning fossil fuels, ignored by all.
Every heatwave occurring today is made more likely and more intense by human-induced climate change. In some cases local factors enhance or counteract this effect. - For the numbers on the PNW wait for our team

Geert Jan passed away on October 12, 2021. We mourn the loss of our friend and colleague, we celebrate his life in this, his final scientific paper. It is on extreme heat - climate change's big, silent killer. Title "We can do better" So, let's!

As a scientist it's not so easy to sign a letter you would have phrased differently, with all the caveats in - but this is so important because it particularly highlights that we need strong democracies and fight inequalities to truly face climate change, we need you EU!

We're still working on answering how large the role of climate change in the ongoing heatwave in South Asia is, but here is how the results will be useful beyond assessing current impacts & inform adaptation to extreme heat.
Today is the day - Angry Weather will be on the shelves. I tried to write non-fiction for people like me, who very much prefer a novel. How & why we do science instead of facts, & of course people!
Given there is some (deliberate) misunderstanding: We need to stop blaming ONLY climate or nature, we need to acknowledge drivers of disasters local AND international, even if that makes snappy headlines more challenging.
βStop blaming the climate for disasters,β says Friederike Otto, climatologist and co-founder
@wxrisk
.
Scientists are increasingly warning that blaming disasters solely on climate change lets policymakers off the hook for poor planning.
If you (unknown colleague, journalist...) want something from me, do NOT address me as Mrs. Otto. I'm not Mr Otto's wife & whether I'm married or not is completely irrelevant. If you can't bring yourself to use my title, use my first name or at least Ms.

@wxrisk
study - drought in Madagascar: Role of Climate Change is small, but huge drought impacts are reminder that climate change is hitting a world in which billions of people live in poverty & many are not adapted to today's climate.
The real question is: how can this rapid increase in heat we showed in our
@wxrisk
study be met by equally rapid adaptation? The 2C result is the number we really need to focus on.
@harrinluke
This is not a good headline. The only thing we can say now is that the impacts are likely made more severe through increased rainfall & sea level rise. Not the storms themselves. The point about vulnerability & exposure is important.
The approval of the

π₯βοΈβοΈThe hottest June on record, the hottest day ever, record shattering rainfall in Rwanda - what is the role of climate change? We know so much now, we don't always need to an attribution study to answer. But sometimes you do - here's when (& where):
Summer is only starting today, but large parts of South America, already suffered two record breaking heat waves. Our new
@wxrisk
study shows they would be not as hot if it wasn't for climate change. Early heat is particularly deadly.
The role of climate change in food insecurity is very far from straightforward, here we use event attribution framing to understand the 2007 Lesotho drought finding how strong trade dependencies led to non-lineaer climate impacts.
In case anyone still doubted that weather is relevant across society and not boring, for all the wrong reasons.
