(1) How to Grow More Food on Less Land
Sustainable Intensification ... how to grow the most food on the least land with the least environmental impact. Currently, livestock production uses 75% of global agricultural land. EU's Nitrate Directive has led to a 30% reduction in fertilizer use. "... simply producing more cannot be thought of as sutainable without looking at how that food is distributed, who it is distributed to and who gets to make those decisions ... it cannot simply be left to concentrated and corporate-dominated 'free markets'". Decreasing food waste is also essential ... currently the world wastes the food output from 5.4 million square miles of land.
(2a) Eating Less Meat Could Save $31 Trillion
If everyone ate less meat we could reduce food-related greenhouse gases by 29% or more and could save $31 trillion by reducing environmental impacts, by cutting healthcare costs and by lowering lost work time. Livestock production leads to ~15% of man-made greenhouse gas emissions.
(2b) Plant-Based Diets Reduce Greenhouse Gas Emissions
To keep "global temperature rise below 2 deg C, we need urgent and dramatic shifts toward plant-based diets" ... If we reduce meat consumption per healthy eating guidelines, we'll cut greenhouse gas emissions from the food sector by 29% ... if everyone goes vegan then we'll cut GHG emissions 70%.
(2c) Need to Cut Food Greenhouse Gas Emissions
Agri-food accounts for ~30% of greenhouse gas emissions. In U.S., we eat 3 times as much meat as is recommended. Reducing our meat consumption and switching from beef to pork or poultry will cut our greenhouse gas emissions.
(3a) James Hansen Says Sea Level Rise Will Occur in Decades, Not Centuries
James Hansen and 18 fellow climate scientists say that faster ice melt from Greenland and Antarctica is slowing ocean circulation which will increase superstorm intensity and increase the rate of sea level rise (perhaps 1 meter in 50 years and 2 meters in 60 years).
(3b) Leading Climate Scientists Say We Have a Global Climate Emergency, Joe Romm
Ice melt from Greenland & Antarctica may be accelerating, slowing normal ocean circulation and leading to 2 meters of sea level rise in 60 years and super-extreme storms. "Fossil fuel CO2 emissions should be reduced as rapidly as practical."
(4) Developed Countries Must Phase Out Fossil Fuels
Our remaining carbon budget is less than 1,000 gigatons (billion tons) of CO2 emissions, to stay below 2 deg C of global warming. If all known coal, oil & gas reserves are burned, it will emit 15,000 gigatons CO2 ... so we must leave most coal, oil & gas unburned, to avoid 14,000 gigatons worth of CO2. Energy efficiency & clean energy are part of the solution but that alone does not require private companies from extracting, marketing & burning fossil fuels. Energy efficiency & clean energy must be the new standard for all investment.
(5) Inoculate Against Climate Denial
5 Methods of Climate Denial: Fake Experts, Logical Fallacies, Impossible Expectations, Cherry Picking, Conspiracy Theories. Logical Fallacies include Oversimplification, Red Herring, Misrepresentation, Jumping to Conclusions, False Dichotomy. One inoculation approach is Fact-Myth-Fallacy.
(6) Trump "Not a Big Believer" in Climate Change
Trump said "I am not a great believer in man-made climate change" ... All major scientific institutions in U.S. (NAS, AAAS, Am Meteorolog. Soc, Am Geophys Union...) have affirmed man-made climate change ... for the presumptive GOP presidential nominee to say he "does not believe" is very concerning ... Trump's Mar-A-Lago club is on a narrow piece of land separating the Atlantic Ocean from the inland waterway ... one would expect Trump as the owner of this property to pay attention to climate projections and guard against climate change risks. A major part of what a U.S. president does is risk management ... Trump show no ability to assume this key role.
(7) Methane's Contribution to Global Warming, Bill McKibben
Our leaders thought fracking would save us from global warming, but they were wrong due to methane leaks. U.S. methane emission increased 30% from 2002 to 2014. EPA has under-estimated methane emissions for years. 3.6% to 7.9% of methane leaks from fracking operations, which causes more climate damage than coal. "The global warming fight can't just be about carbon dioxide any longer. ... Coal and oil and natural gas have to be left in the ground. All of them."
(8) Environmental Issues Fuel Violent Conflicts, Chris Mooney
Environmental issues can threaten food security, increase water stress, undermine the economy, displace populations and lead to civil unrest. Natural resource issues fuel at least 40% of internal conflicts. Competition for land and water and environmental degradation (deforestation, pollution, redirected water sources) can drive conflicts.
(9) TPP Climate Dangers
TPP would allow corporations to challenge offshore oil drilling restrictions and federal land drilling restrictions. "To keep fossil fuels in the ground, we cannot afford the new roadblocks posed by the TPP and TTIP."
(10) Climate Change Food Security
Singapore imports 90% of its food, mostly from Malaysia, Japan & Brazil. By 2030, climate change may reduce rice production by 18% & fish catch by 60%. Recommendations for food importing countries: Invest in Food Stockpiling & Storage and Consider Climate Impacts for Food Diversification.
(11) Wind & Solar Growing But Not Fast Enough, Brad Plumer
Renewables & nuclear make up 33% of global power but we need to be over 90% by 2050.
