Answer:
Climate change is already happening: temperatures are rising, drought and wildfires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising. These ever-changing trends mean that scientists have to be well acquainted with all this which requires a great deal of understanding and patience.
The political interests in research often limit the results and many a time misleading
Data for climate research is in many instances difficult to access, often at a price, and according to the source and type of data, the formats for retrieval can be very different. In addition, data may not be available for the same time and space scales. There is often an incompatibility between socio-economic and physical data, both necessary for climate modeling efforts because data collection is generally carried out by different agencies for different purposes. This means scientists have to analyze this data as useful and then research on it.
