Quotes About Anthropogenic

The construction of permanent sea walls can be taken up only in places where there is sea erosion due to heavy anthropogenic pressures. The locations for such non-living barriers should be determined on the basis of a carefully conducted erosion-vulnerability analysis.

Whether the ice caps melt, or expand - whatever happens - the anthropogenic global warming theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology.

It could be the case that all the studies supporting a warming planet are wrong; science always leaves that door open, but anthropogenic climate change remains the best explanation for a mountain of data that scientists have been poring over for a century.

Climate change is real and anthropogenic; and the 5th Assessment Report of the IPCC has left the deniers little room for manoeuvre, but they are swiftly morphing into a new breed that accept the climate is changing but like to suggest this may have positive benefits.

The best scientific evidence suggests temperatures are rising, and the best scientific evidence suggests man-made anthropogenic carbon emissions have some substantial thing to do with that. However, does that mean the trend will continue forever? We don't know.

Anthropogenic": What agenda allows us to put "human influence" (greenhouse gases, aerosols, emissions) to the fore and celestial mechanics (and Mother Nature) to the rear?

How about methane? It too is chemically unstable, and yes, some of it is anthropogenic, but as we've seen, methane has nonliving agents as well.

Another side effect of fertilization that is receiving more attention is the generation of nitrous oxide by bacterial decomposition of nitrates. Not only is N2O a greenhouse gas but, on a hundred-year time scale, it has a nearly three hundred times higher global warming potential than carbon dioxide, the dominant greenhouse gas. But because of its relatively small emissions, N2O is responsible for only about 6 percent of recent anthropogenic greenhouse gas emissions.

Energy is not a single, easily definable entity, but rather an abstract collective concept, adopted by nineteenth-century physicists to cover a variety of natural and anthropogenic (generated by humans) phenomena. Its most commonly encountered forms are heat (thermal energy), motion (kinetic or mechanical energy), light (electromagnetic energy) and the chemical energy of fuels and foodstuffs.

By the 1960s scientists had expressed concerns about the possibility of an anthropogenic climate change to presidents of both parties. At the Rio Earth Summit in 1992 the industrialized countries seemed to agree that by 2000 they would stabilize their GHG emissions at 1990 levels. Yet global emissions are still increasing, the atmospheric concentration of carbon dioxide is now almost 10% greater than it was in 1992, we have already experienced a warming of .8°C,

Using whatever data he could find, Callendar claimed that there had already been a 10% increase in atmospheric CO2 and that an observable, anthropogenic warming had already begun. What became known as the "Callendar Effect" was the claim that the combustion of fossil fuels would lead to increases in the atmospheric concentration of carbon dioxide, which would warm the earth.

Making the documentary was an extraordinary experience and it really hit home to me the quasi-religious nature of this anthropogenic global warming cause. These people really have found religion.

By the early 2000s, dangerous anthropogenic interference in the climate system was under way. Fires, floods, hurricanes, and heat waves began to intensify. Still, these effects were discounted.

Two crucial developments during the presidential campaign year of 1988 changed climate science forever. The first was the creation of the Intergovernmental Panel on Climate Change. The second was the announcement by climate modeler James E. Hansen, director of the Goddard Institute for Space Studies, that anthropogenic global warming had begun. An organized campaign of denial began the following year, and soon ensnared the entire climate science community.
