Almost immediately, and predictably, the findings were criticized by both sides in the debate over what to do, or not do,
about human effects on the climate.
Much of what you are calling «evidence» that humans have a hand in the warming, whether provided by yourself or the IPCC or the Mail and Guardian, is merely evidence of warming and says nothing
about any human effect on the climate.
In any case, one decade is not long enough to say anything
about human effects on climate; as one forthcoming paper lays out, 17 years is required.»

In 1996, when
climate research was more certain
about the link between fossil fuel combustion and
climate change than during the time of Shaw's memo, Exxon's new chairman and chief executive Lee Raymond said in a speech in Detroit: «Currently, the scientific evidence is inconclusive as to whether
human activities are having a significant
effect on the global
climate.»
According to one study that looked at eight fuel aridity metrics in the Western U.S. and modeled
climate change's
effects on them,
human - caused
climate change accounted for
about 55 percent of the observed increases in fuel aridity between 1979 and 2015 (Figure 6), and added an estimated 4.2 million hectares of forest fire area between 1984 and 2015.7 Based
on all eight metrics, the Western U.S. experienced an average of 9 additional days per year of high fire potential due to
climate change between 2000 and 2015, a 50 percent increase from the baseline of 17 days per year when looking back to 1979.
I have wanted to learn more
about the
effect of
human - caused
climate change
on the natural world.
The bottom line, according to a group of experts not involved in any of these studies: Scientists don't know much
about how sunlight interacts with our planet, and until they understand it, they can't accurately predict any possible
effects of
human activity
on climate change.
If our ultimate goal is to reduce carbon emissions and, hence, to save humanity, we must realize the psychological
effect that the disturbing truth may have and teach
about climate change and energy in a carefully thought - out manner based
on the available research
about human psychology.

On the other hand, despite the overwhelming evidence that global warming will transform the Earth's climate for centuries, with fearful consequences for human health and wellbeing (not to mention the survival of many species and ecosystems), the world can not agree to significant reductions in greenhouse gas emissions because of concerns about the effects on economic growt
On the other hand, despite the overwhelming evidence that global warming will transform the Earth's

In contrast,
climate models, useless as they may be in other respects, can at least pretend to indicate specific impacts
on the world, from which direct inferences may be made
about effects on humans and the environment.
I added several comments e.g.
about the (minor) impact of
human aerosols
on temperature, which implies that the
effect of GHGs is also less than incorporated in
climate models.
There are many things
about climate that I accept — that
human emissions have
effect on increases of CO2 content in the atmosphere (while the concentration is driven largely by temperature and resulting solubility of CO2 in sea water,
humans still provide the surplus), that this increased CO2 content has
effect on temperature (and indirectly
on other aspects of
climate), that
humans affect the
climate (but not just through CO2 but also through UHI, agricultural changes, pollution etc), that temperatures have risen since half of the last century.

This paper finds that under a wide range of assumptions
about future growth in wealth and population, and
about the
effects of
human - caused
climate change, in every case there is far greater potential to affect future losses by focusing attention
on the societal conditions that generate vulnerability to losses.
The letter begins «As you know, an overwhelming majority of
climate scientists are convinced
about the potentially serious adverse
effects of
human - induced
climate change
on human health, agriculture, and biodiversity.»
I know there have been surveys that aim to show the level of consensus
on the existence of man - made
climate change, but were
climate scientists polled
about «potentially serious adverse
effects...
on human health, agriculture and biodiversity»?
Given the high uncertainty
about the net
effect of
human carbon dioxide emissions
on global temperatures, we only see natural changes in
climate.
The
climate system is highly non-linear8 and relatively little is known
about the
effect on temperature changes resulting from
human contributions to the changing three - dimensional distributions of ozone and aerosols, either or both of which may have been partially responsible for the observed discrepancy between surface and lower to mid-tropospheric temperature changes.

In March 2007, Hansen told the House of Representatives Committee
on Oversight and Government Reform, «The
effect of the filtering of
climate change science during the current administration has been to make the reality of
climate change less certain than the facts indicate, and to reduce concern
about the relation of
climate change to

We wrote
