... in CV %). The overall average increase of wheat yield by the 2050s (1.55 t/ha) is very similar to the yield
increase predicted in the earlier scenarios (Richter et al., 2002). The reasons for this result are the increase in
RUE due to CO2 elevation and the acceleration of development by five to six ...
... In contrast to our exploding human population, many species are dwindling––often due to people’s actions (e.g.,
hunting, degrading environments, and introducing nonnative species). Still, many past effects pale compared to the
threat of global climate change. (Nb. We will henceforth
largely use the ...

and underground water sources (CRISP 2011).

• Temperatures decrease with increasing latitude north and south from
equator. Equator receives more solar energy.
• Temperature range is much greater for the continents than for the

... their citizens. This will necessitate a wide range of measures, including significant additional energy use in those countries and compensating reductions in industrialized countries. The transition to a sustainable future will require investments in energy efficiency and non-fossil energy sources. ...

mainly for the energy and transport sectors, and
strategies have been elaborated to reduce the impact. Gradually, knowledge about emissions of
other greenhouse gases besides carbon dioxide has

... Here is what’s new: This year’s INDCs are supposed to be universal. In the previous system (under
the 1997 Kyoto Protocol), only the rich countries were responsible for emissions reductions. Now all
countries are expected to act, and the “firewall” between richer and poorer countries is being taken ...

... Ignoring sinks is indeed problematic and all factors that have an effect on the atmospheric GHG
concentrations must be taken into account. But we claim that EE can do so.
For a start, Caney’s claim is somewhat misleading. Instead of emissions, anthropogenic forcing
should matter, he claims. However, ...
... We selected two climatic variables for regression analysis that are consistently correlated
with species richness in numerous studies: mean annual temperature and annual
