NASA; climate change; and how three speakers at JPL informed me about greenhouse gases

Last night, G. Ripley checked out the JPL in la canada flintridge, CA. NASA JPL is jet propulsion laboratory. Brian W. was the host of the Von Karma Lecture on 'NASA: climate change in the 21st century and beyond.' The three speakers were Dr. Graeme Stephens; Dr. Kate Marvel; and Dr. Brian Kahn. Graeme is from Australia and South Africa; and he spoke about radioactive impacts plus cirrus cloud frequency. He spoke about water cycles, and how 97-98% of the earth is covered with water. He spoke about albedo also, which is the sunlight of the earth. After Dr. Graeme S. spoke, the next speaker was Dr. Brian Kahn. Brian talked about ECF, effective cloud fraction. He mentioned the ABI, which is the advanced baseline imager. Both acronyms are important in climate change. Brian mentioned that there is a 41 degree shift in Fahrenheit, over the past 10 years. This huge increase in the temperature is part of global warming. He mentioned that clouds will not save us from global warming. He mentioned that carbon dioxide is emitted, and this is CO2. His last question to everyone was 'will climate change be bad for the world?'; and the crowd was very happy to hear this question in such a relevant topic. The last speaker was Dr. Kate Marvel. She spoke about water vapor, which is H2O. She is from the Goddard Institute of Space Studies. She mentioned that emissions have to be cut. She mentioned that clouds and storms on a weather map are effective. The clouds on a weather map, are good for forecasting also. There are geostationary satellites, which are important in the sky and in space. The two major greenhouse gases are carbon dioxide, and water vapor. After she finished her speech, all three of the speakers answered questions from the crowd. It was a very informative night for me. I asked a question to Dr. Marvel; and to Dr. Kahn. Both of them answered my questions, about greenhouse gases and ECF. As G. Ripley closes this piece, the reader will find out different parts of climate change to be interesting. It was my first time at JPL; and the 75 minutes there were fun and exciting for me. The JPL has a visitor center, which covers the nine planets and telescopes/satellites too.
