Here is the for the hearing, which includes link to all of the testimonies and also the webcast. My testimony can also be downloaded here . Here is the content of my verbal testimony: The central issue in the scientific debate on climate change is the extent to which the recent (and future) warming is caused by human-caused greenhouse gas emissions versus natural climate variability that are caused by variations from the sun, volcanic eruptions, and large-scale ocean circulations.https://climatechangedispatch.com/wp-content/uploads/images_pics8_judth_curry_testimony.jpg
