1) Technological fixes can be used to address rising temperatures. For example, carbon capture (capturing carbon from the atmosphere and depositing it in the bedrock below earth’s surface), ocean fertilization (scattering iron powder throughout the oceans, providing nutrients to boost the phytoplankton), and alternative energy sources (such as wind, water, and solar) are all technological fixes designed to address climate change. Socio-technological fixes, such as decreasing meat consumption, building eco-friendly buildings, and limiting excess waste, are much more limited to the individual, and it could be argued that these changes cannot stack up against the contributions of farming, industry, and energy production. These changes depend on global empathy, cooperation, and sustained effort.
2) No, climate science is not in its infancy. In fact, climate science has been studied since the 18th century and gained momentum in the 19th century. Michael Reid tells the story of John Tyndall, a climate scientist who worked in the late 1800s, studying glaciers, radiation and absorption of sunlight, and which molecules absorb heat the most effectively. So the argument that climate science is unreliable due to its “age” is not viable.
