Summary of El debate - Cambio climático - 21-08-11 (1 de 4)

00:00:00 - 00:20:00

This YouTube video discusses the debate over climate change, with a focus on the evidence that humans are responsible for recent global warming. Dr. Camilloni discusses the role of the oceans in absorbing and releasing energy, and how natural fluctuations in climate can be seen as early indicators of human-caused climate change. The video finishes by noting that there is no convincing evidence of a previous global warming event that was as sudden and dramatic as the current warming trend.

• 00:00:00 In this YouTube video, two scientists present their views on the human role in climate change. The first, Dr. Inés Camilloni, is a doctor with a background in atmospheric sciences and research at the Marine and Atmospheric Research Institute (MARIN). The second, Dr. Tristan Seaman, is a professor of natural sciences at the National University of Quilmes and a member of the Intergovernmental Panel on Climate Change (IPCC). Both scientists speak about the risks and potential consequences of climate change, and discuss man's role in causing it. Around the 10-minute mark, the public is allowed to ask questions. Among those asked is Juan Ignacio Sánchez, a retired professional basketball player who represented Argentina in the 2004 Athens Olympics and Beijing Olympics, and Pepe Sanchéz, a lawyer and physical education teacher who has a degree in history from the University of Tennessee in the United States. All in all, the video provides a good overview of the climate change debate and the human impact on it.
• 00:05:00 The video discusses how climate change is constant, part of the natural evolution of the planet, and that humans have had a significant impact on the climate over the past 50 years. It also discusses how scientists use data and evidence to build a case for human-caused climate change, and how each individual has a responsibility to share this information with others in a way that will reduce uncertainty. Finally, the doctor in charge of climate change at the National Academy of Sciences gives her opinion on the matter.
• 00:10:00 The video discusses the complexity of climate, in particular, how it relates to the whole planetary system. In my opinion, it cannot be reduced to analysis of a single variable and trying to extrapolate over the last 50 years of data, a process that can take many more years. From my perspective, reductionism is absolutely wrong in my opinion and does not dismiss human impact on climate change as an organism within the planet, but I do not believe that it is the main driver of that change. Another point of discussion is water and its role in climate change. The DR. CAMILIA NIETO-MARTINEZ said that the reason climate change is adapting well over the past 50 years is thanks to the availability of more detailed data. However, when it comes to the beginning of this process, around the time of the industrial revolution, data will be less reliable or will have less stations. This issue is connected to the fact that, over time, many places and stations that were used to collect data have changed due to the environment. For example, rural areas have become urban, which has led to an increase in temperature in those measures that are related to urban effects such as islands of heat, caused by large cities. This, in turn,
• 00:15:00 The video discusses the debate over climate change, and discusses the evidence that humans are responsible for recent global warming. It also discusses the potential effects of climate change, including increased sea levels and reduced ice coverage in the north. Three testimonials are presented, each in support of the position that the doctora Camilión is taking. The video finishes by noting that there is no convincing evidence of a previous global warming event that was as sudden and dramatic as the current warming trend.
• 00:20:00 In this YouTube video, Dr. Camilloni discusses the debate over climate change, discussing the evidence that suggests a dramatic increase in global temperature in the past. He also discusses the role of the oceans in absorbing and releasing energy, and how natural fluctuations in climate can be seen as early indicators of human-caused climate change.
