This video sees an eccentric Mr Phil Williamson tell us objectively what can be done about climate change.
Mr Williamson reminds us that the overall objective has not changed as there still is too much co2 being put into the atmosphere. The basic problem as Mr Williamson reminds us is that we need to stop adding co2 into the atmosphere and it is not enough just to reduce co2 emissions but we must also actively remove co2 from the atmosphere.
Greenhouse Gas Removal (GGR) refers to a technique that removes greenhouse gases from the atmosphere through mechanical means. A more common umbrella term is Carbon Dioxide Removal (CDR), which excludes methods that remove other greenhouse gases such as methane.
As a rapidly warming world manifests heat waves, floods, droughts and hurricanes, geoengineering – large-scale manipulation of the Earth’s natural systems – is being presented as a strategy to counteract, dilute or delay climate change without disrupting energy- and resource-intensive economies. Alarmingly, current debates about this big techno-fix are limited to a small group of self-proclaimed experts reproducing undemocratic worldviews and technocratic, reductionist perspectives. Developing countries, indigenous peoples, and local communities are excluded and left voiceless.
Mr Williamson talks us through the three main methods for removing carbon dioxide from the atmosphere. Those are: Ocean re-fertilization, Coastal blue carbon, Adding alkalinity/enhanced weathering.
The quest for negative emissions continues. We hear also from Mr J Manning and he tells us about how his job is basically to translate what scientists say in theory and to produce actionable plans with that information. He tells us about how his organisation has grown as well to include lots of countries, NGO’s and more has continued to grow and expand.
Mr Manning is working to build action plans to adapt to change. There are currently 8 different studies to identify the effectiveness of sea grass applications just on the west coast of LA along with nutrient modelling. Mr Manning thinks if you can control nutrients then you can control emissions.
Ocean acidification is something that really needs combating. Ocean acidity has already increased by 30 percent and is expected to double over pre-industrial levels by the end of this century as a result of the ocean absorbing one-third of the atmospheric carbon dioxide generated by human activities. Significant adverse impacts on fisheries and marine ecosystems have already been documented due to ocean acidification and these impacts will worsen in the future.
So with data from interesting studies and fresh talks from informed lecturers, this video is definitely one to watch. Keep abreast of the global situation and follow the links below to find out how you can also help the climate continue to improve positively.
