Climate Science: Transparency against Misinformation

We live in a time where information flows at incredible speeds, but also in an era where misinformation has become a silent, persistent, and dangerously effective enemy. This is especially serious when we talk about Climate Change, a global phenomenon that affects every corner of the planet and requires responses based on evidence, not on opinions or particular interests.

Faced with this reality, the scientific community has opted for the best possible tool: transparency. There is no better antidote to lies than the truth presented in an open, accessible, and verifiable manner. This is precisely the great asset of contemporary climate science: offering data that any person, institution, or government can consult, analyze, and contrast.

For years now, researchers studying the climate and its evolution have opted for an open science approach. Not only do they publish the results of their studies, but they also share the numerical models used—often under open-source licenses—and the data sets that support their conclusions.

This approach has multiple advantages. For starters, anyone with scientific knowledge can examine the data, replicate experiments, propose improvements, or point out possible errors. Far from weakening science, this practice strengthens it. Knowledge becomes more robust each time it is validated by other independent researchers.

This is how scientific consensus is built: not by imposition, but by the accumulation of evidence that withstands the most rigorous scrutiny. And in the case of climate change, that consensus is already overwhelming. Not because a single source says so, but because thousands of scientists in dozens of countries have reached similar conclusions by observing and studying the same reality from different angles.

Today, there are numerous initiatives that offer the public free access to climate data and analysis tools. One of the most important is NASA Earth Data, which allows you to explore interactive visualizations of variables such as temperature, sea level, and ice cover at the poles.

Another reference source is Copernicus, the European Earth observation program. Through its website   https://www.copernicus.eu/en

   , you can consult reports, download data, and even view interactive maps showing how various environmental parameters are changing around the world. And best of all: it is available in multiple languages, further democratizing access to this valuable information.

These tools are not only useful for researchers or professionals. They are also designed for curious citizens, journalists, educators, and public policymakers who want to better understand the current state of the planet.

Disinformation continues, but it is running out of arguments. Despite all this openness, deniers and disinformation campaigners have not disappeared. Some continue to manipulate data, take phrases out of context, or sow doubt with empty rhetoric. But they are finding it increasingly difficult. Because science not only speaks facts, but makes them available to everyone.

When anyone can directly access satellite data, climate models, and assessment reports, hoaxes lose their hold. Fanatics will continue to shout, yes, but they no longer have a monopoly on the message. Today, anyone who wants to know the truth can easily find it.

Dear friends, it has never been easier to be well-informed about what is happening to our planet's climate. With just a click, we can access solid data, prepared by experts, peer-reviewed, and put at the service of the common good. What was previously only available to academics or specialized institutions is now available to anyone with an internet connection and the desire to learn.

Therefore, it is important that, as a society, we know how to distinguish between reliable sources and biased discourse. Let us value the rigorous work of those who dedicate their lives to studying the climate, and let us use that information to make informed decisions, both in our daily lives and in the exercise of our citizenship.

The planet speaks to us every day through science. And if we listen carefully, we will see that the message is clear, urgent, and full of data. The truth is out there—and it's public.

Now we just need to act with the required urgency.
