The insecticides I have in mind are neonicotinoids, which have devastated bee populations throughout the world. Seeds treated with neonicotinoids are also toxic to birds (some birds more than others). A few years ago, the European Union banned various neonicotinoids from all agricultural fields because of the harm they caused bees and birds. Follow-up studies are now trickling in from Europe and the results have been quite illuminating. Here are some findings…
The dinosaurs never went extinct. Let’s keep it that way.
Yards make up roughly 17 percent of the continental United States: almost four times the land area taken up by national, state, and regional parks. And those yards are dominated by turf grass, because Americans love their lawns. Which is a shame since lawns tend to be pollinator wastelands and most terrestrial life on earth depends on the labor of pollinators. I’m talking birds and bees.
We have to go beyond categorical, either/or thinking to solve the problem of agriculture and the environment. It’s not about organic versus conventional. It’s about how to grow more food on less land while reducing environmental harm. So that soils remain healthy, more land reverts to wild habitat, and the rest of the biosphere isn’t poisoned by pesticides and fertilizer run-off (including manure).
Obviously there’s no one-to-one association between GDP and CO2 emissions. Other factors come into play, like the particular fuel mix used to generate electricity in a given locale. Speaking of which, look at France…
“Around the world, forests are shrinking due to deforestation, urban development and climate change, but in Europe that trend has been reversed. …Large areas of the continent have seen a forest boom that means today more than two-fifths of Europe is tree-covered. Between 1990 and 2015, the area covered by forests and woodlands increased by 90,000 square kilometres - an area roughly the size of Portugal.”

That’s almost 30% more beef produced per cow since 1961. And yet the amount of land devoted to livestock pasture has been declining for the past twenty years…How did we do it?
Republicans used to be more gung-ho about saving endangered species and other environmental causes, e.g., a Republican president established the Environmental Protection Agency and the late, great John McCain fought many battles to protect natural habitats. But then the ardor cooled. Why was that?
Depending on the scenario, average global temperatures may rise anywhere from less than 2°F to over 9°F by 2100 (.9°C – 5.4°C). The question is how to plan for such a range of possible climate futures? I offer some thoughts from people who make a living pondering this very question:
“Uncertain changes in climate, technological, socio-economic and political situations, and the dynamic interaction among these changes, and between these changes and interventions, pose a challenge to planners and decision-makers. Due to these uncertainties, there is a risk of making an inappropriate decision (too little, too much, too soon, or too late).” Kwakkel, J. H., M. Haasnoot, et al., 2016.
Note that I’m not endorsing some measures over others. None of the above measures are mature technologies and none should be excluded from consideration. As energy systems engineer and Princeton professor Jesse Jenkins put it:
“If we’re really in a ‘climate crisis,’ then you go to war with your full arsenal, you don’t hold anything back. And you don’t purposefully make this crisis harder by limiting our already limited options.”
Per the IPCC glossary, decarbonisation (British spelling) aims to achieve “zero fossil carbon existence” and typically refers to a reduction of the carbon emissions associated with electricity, industry and transport. Examples include methanisation, biomass co-firing, carbon capture and storage, and many more. Here’s a list of 18 decarbonisation measures…
Climate change mitigation pathways are a series of measures taken to reduce or prevent greenhouse gas emissions or to remove greenhouse gases from the atmosphere. Demand-side measures are policies and programs for influencing the demand for goods and/or services. Without further ado, here are 17 demand-side measures found in the 2018 IPCC report, “Mitigation pathways compatible with 1.5°C in the context of sustainable development”…
Per the IPCC, here are a few of the “key uncertainties” (reflecting low or very low confidence) regarding the effects of climate change…Global-scale trends in drought…Changes in tropical cyclone activity…Global-scale trends in cloud cover (as well as cloud-climate feedback effects)…Global-scale ocean sub-surface temperature trends and variability…Global-scale and regional changes in precipitation levels….
Per “Analysis: Global coal power set for record fall in 2019” (Carbon Brief), global electricity production from coal is set to fall by around 3% in 2019, the largest drop on record. The projected drop is due to record falls in developed countries, including Germany, the EU overall, South Korea and the United States.
The primary fuel reduction method used by the DOI was “vegetation treatment”, which includes thinning and timber harvest; controlled burns, chemical treatments; targeted grazing; mechanical removal; mowing or cutting; logging; and fuel breaks, or gaps in vegetation that limit fire spreading or speed of spreading. Vegetation treatment is still an method in progress.
This is a Reblog of “The toxic rhetoric of climate change” by Judith Curry. Posted on December 14, 2019 (link here). I highly recommend you check out the comments on original blog and to explore Judith Curry’s other posts.
“…A new report by the Global Commission on Adaptation, a group convened by 20 advanced and emerging economies, identifies $1.8trn in potential adaptation investments which, if realised between 2020 and 2030, would yield estimated net benefits of $7.1trn.” The Economist Humanity will find ways to adapt to climate change. September 19, 2019…All the adaptations in the above list would be good ideas even if the climate stopped warming today. Meaning that even climate change skeptics could get behind these adaptations because they address current threats to humanity and the environment.
For the record, there is nothing in the UN Report about “mass extinctions” or large parts of the planet becoming “uninhabitable” unless we abide by the Paris Agreement (check for yourself, here). And despite the scary introduction, the UN report’s specific recommendations are quite doable without “fundamental structural changes”. Here are the main recommendations:
The Promise of Science: “…truth [will emerge] as a large number of flawed and limited minds battle it out.” (Jonathan Haidt).
According to the just released Responding to Rising Seas: OECD Country Approaches to Tackling Coastal Risks, Australia, Belgium, Canada, Chile, Denmark, Estonia, Finland, France, Germany, Greece, Ireland, Israel, Italy, Japan, Korea, Latvia, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Slovenia, Spain, Sweden, Turkey, and United Kingdom all have coastal adaptation plans in place.
