Geologist Viv Forbes: "Abandon the Zero Emissions farce. Bullock-drawn wagons, camel trains, and horse teams may achieve the zero-emissions dream, but they will not keep our cities fed — there are no electric tractors, dozers, or road trains. This Lockdown Depression is giving us a taste of "Zero Emissions." It is a bitter taste. It leads to unemployment and poverty with no proven benefits for nature or the climate."
Spencer: "This is because the estimated reductions in CO2 emissions (around -11% globally during 2020) is too small a reduction to be noticed against a background of large natural variability. The reduction in economic activity would have to be 4 times larger than 11% to halt the rise in atmospheric CO2."
UN Environment claims Covid-19 is disrupting food production which has already been battered by climate adversity. But just last November, the UN Agriculture body said “reserves held by the five major exporting countries could rise to a five-year high, primarily on the back of another foreseen build-up in India.”
Analyses are nearly universal in finding that global carbon emissions will decline from the record peak in 2019. The declines, largely driven by a steep reduction in vehicle emissions, have been so large that photographs from space reflected the change. The International Energy Agency, a policy advisory group to 30 member countries, projects that global carbon emissions are set to fall by 8%, or levels the world hasn't seen for a decade. Estimates of the full drop in carbon emissions vary as analysts adjust their models around the coronavirus pandemic, but the lowest estimates still expect about a 5% drop in emissions. “This may sound small at first, but it is the largest drop since World War II, as emissions have generally increased year-over-year, even during recessions,” Ankur Desai, a professor of atmospheric sciences at the University of Wisconsin-Madison, told USA TODAY.
