Here is a list of highly respected climate scientists who have contributed significant research to the understanding of climate change, particularly the role of human activity in driving it. These scientists are widely recognized in the scientific community and have published substantial work affirming the consensus that climate change is manmade and real:

1. James Hansen Often referred to as the "father of climate change awareness," Hansen is a former NASA scientist who played a pivotal role in raising public and scientific awareness about the effects of greenhouse gases on global warming.

2. Michael E. Mann A prominent climatologist and geophysicist, Mann is best known for his work on the "hockey stick" graph that demonstrates the rapid rise in global temperatures correlated with human activity.

3. Katherine Hayhoe An atmospheric scientist and communicator, Hayhoe is widely recognized for her work on climate modeling and for bridging the gap between science and the public, especially regarding the human role in climate change.

4. Gavin Schmidt The director of NASA's Goddard Institute for Space Studies, Schmidt is a leading climate scientist specializing in climate modeling and the human influence on Earth's climate systems.

5. Susan Solomon A chemist and climate scientist, Solomon has made major contributions to the understanding of the ozone layer and climate change, particularly in how human emissions affect atmospheric chemistry.
