# unga-climate-classifier

This model is a fine-tuned version of [microsoft/deberta-v3-base](https://huggingface.co/microsoft/deberta-v3-base) trained to classify climate-related sentences in English using a dataset of 5,600 annotated sentences from the United Nations General Assembly Corpus. It was developed to build the Executive Comparative Climate Attention (ECCA) indicator, introduced in a [paper](https://doi.org/10.1162/glep.a.1
) published in Global Environmental Politics.


# How to use

```python 
from transformers import pipeline classifier = pipeline("text-classification", model="mljn/unga-climate-classifier")

text = "Climate change poses a fundamental threat to our future."

result = classifier(text)

print(result)

[{'label': 'climate', 'score': 0.9988275170326233}]

```
