Our planet is getting hotter at an alarming rate. Climate change is one of the most serious global issues today. Its affect every single human being on Earth. So it seems perfectly logical that are written in the global language: English.

And yet, it is precisely because it is written in English, that climate science is largely inaccessible to the majority of people globally.

To explain this apparent contradiction, we need to look at some numbers. Nearly 90% of scientific publications . This is a staggering dominance of just one language. But English, often called a global language, is only spoken by a minority of the world’s population.

How do we know that most people in the world don’t speak English? English the main language of society in only a handful of countries: the UK, Ireland, the US, Canada, Australia and New Zealand. The population of these countries, combined, amounts to about 400 million – a very small percentage of the world’s population.

In many other former British colonies, such as India, Nigeria or Malaysia, English exists alongside other languages. In these contexts English tends to be an elite language, used mostly by urban, middle-class, well-educated people. Elsewhere, English functions as a lingua franca, used mostly in transnational communication.

Given these diverse scenarios, it is extremely difficult to estimate the number of speakers of English with any precision. About 20 years ago, linguist suggested that the number may be somewhere between 1 and 2 billion. Even if we take the upper limit of that extremely large range, we’re talking about only one quarter of the world’s population. This means that three out of four people in the world do not speak English.

That means at least three quarters of the world’s population do not speak the language in which the science about climate change is disseminated globally. At the same time, languages other than English are marginalised and .

So this linguistic inequality creates an imbalance in the distribution of scientific knowledge about climate change. But it also reinforces two other types of existing inequality.

One has to do with the production of scientific knowledge in general, which is disproportionately emanating from the two main Anglophone countries: the US and the UK. Out of the top , 91 are based in these two countries.

The other form of inequality has to do with social injustice. Scientific literature is almost exclusively written in English. But this language is virtually unknown by most people, especially in developing countries. And so, are precisely those where access to scientific literature about it is severely limited.

What is the solution? Unesco’s , is attempting to tackle the problem. “make scientific research from all fields accessible to everyone for the benefits of scientists and society as a whole”. One of is to “ensure that scientific collaborations transcend the boundaries of geography, language and resources”.

Breaking language barriers

Achieving the objectives set by Open Science is no easy task. One approach is to break the barrier of English monolingualism by promoting multilingualism.

On the one hand, opportunities must be created for scientists from around the world to communicate their research and their scholarship in languages other than English.

On the other, the great technological , especially with the advent of AI, should be put to use in order to ensure that content is available in languages other than English. This is precisely the goal of , a non-profit organisation whose mission is to “make the climate movement more accessible to those who don’t speak English” by translating information into more than 100 languages.

These kinds of concrete efforts offer hope for climate literacy and, consequently, for action to lessen the impact of climate change.
