Quiero leer otro artículo interesante sobre el cambio climático.

In Spanish, the subject pronoun is often omitted because the verb ending already tells you who the subject is.

• Quiero = I want
• The -o ending shows it is yo

So Quiero leer... is completely natural. You could say Yo quiero leer..., but that usually adds emphasis, contrast, or clarification.

For example:

• Quiero leer otro artículo. = neutral
• Yo quiero leer otro artículo. = I want to read another article

After querer + another verb, the second verb stays in the infinitive.

So:

• Quiero leer = I want to read
• Quiero comer = I want to eat
• Quiero estudiar = I want to study

This is very common in Spanish. The first verb is conjugated, and the second verb is left in its basic form.

Here otro means another.

In Spanish, otro normally does not take un before it in this kind of sentence. So:

• otro artículo = another article

Not:

• un otro artículo ✘

That sounds wrong in standard Spanish.

Compare:

• otro artículo = another article
• el otro artículo = the other article

So otro already carries the idea of another/other, and that is why un is not used.

Artículo has a written accent because the stress falls on the third-to-last syllable:

• ar-TÍ-cu-lo

Words stressed on the third-to-last syllable are called esdrújulas, and they always take a written accent in Spanish.

The accent mark helps show the correct pronunciation.

In Spanish, descriptive adjectives often come after the noun.

So:

• un artículo interesante = an interesting article

This is the normal order.

You can sometimes put an adjective before the noun, but that often sounds more literary, emphatic, or stylistically marked. For everyday Spanish, otro artículo interesante is the most natural choice.

It does agree in number, but not all adjectives show gender with -o or -a endings.

Interesante is one of those adjectives that has the same form for masculine and feminine singular:

• un artículo interesante
• una idea interesante

But it does change in the plural:

• artículos interesantes
• ideas interesantes

So it agrees, just in a different way.

Yes. In this sentence, sobre means about, on the topic of, or concerning.

So:

• un artículo sobre el cambio climático = an article about climate change

Even though sobre can also mean on or over in physical contexts, it is very commonly used to mean about when talking about a topic.

Another possible expression is acerca del cambio climático, but sobre is very natural here.

Spanish often uses the definite article with general concepts, especially when referring to something understood as a known idea or phenomenon.

So:

• el cambio climático = climate change

In English, you usually drop the in this kind of expression, but Spanish often keeps it.

After sobre, saying just sobre cambio climático would sound unnatural here. Sobre el cambio climático is the normal form.

Because they describe artículo, which is singular.

Agreement in Spanish means words that describe a noun must match it.

Here:

• artículo = masculine singular
• otro = masculine singular
• interesante = singular

If the noun were plural, the sentence would change like this:

• Quiero leer otros artículos interesantes sobre el cambio climático.

So the form of the surrounding words depends on the noun.

A little, yes, but the original order is the most natural.

The standard order is:

• Quiero leer otro artículo interesante sobre el cambio climático.

You might also see something like:

• Quiero leer otro interesante artículo sobre el cambio climático.

But that sounds more stylistic or literary.

If you move words around too much, the sentence can sound unnatural or change emphasis. For a learner, the original version is the safest and most natural pattern.

Cambio climático is the standard term for climate change. It is the established expression used in news, science, and everyday discussion.

Cambio del clima is more literal, like change in the climate or change of the climate, and it is less idiomatic in this context.

So if you mean the global phenomenon people usually talk about, el cambio climático is the best choice.

Yes. In Spanish, quiero is often perfectly normal and not as blunt as I want can sometimes sound in English.

So:

• Quiero leer otro artículo...

can simply mean:

• I want to read another article
• I’d like to read another article

Depending on context, English may prefer I’d like to... because it sounds softer, but the Spanish quiero is completely natural.
