I don't know who to blame more: public relations agencies/people who work for meteorological organizations wanting to improve the political climate for spending money on weather or reporters who lean toward hyping global warming wanting the public to believe we can accurately forecast the weather years into the future and thus detect differences in the weather caused by climate change. The answer is likely both.
