The ability of the oceans to take up carbon dioxide can not keep up with the rising levels of greenhouse gases in the atmosphere, which means carbon dioxide and global temperatures will continue to increase unless humans cut their carbon dioxide emissions.
In a paper published this month in Geophysical Research Letters, Lovejoy concludes that a natural cooling fluctuation during this period largely masked the warming effects of a continued increase in human - made emissions of carbon dioxide and other greenhouse gases.
A few of the main points of the third assessment report issued in 2001 include: An increasing body of observations gives a collective picture of a warming world and other changes in the climate system; emissions of greenhouse gases and aerosols due to human activities continue to alter the atmosphere in ways that are expected to affect the climate; confidence in the ability of models to project future climate has increased; and there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.
Since levels of greenhouse gases have continued to rise throughout the period, some skeptics have argued that the recent pattern undercuts the theory that global warming in the industrial era has been caused largely by human - made emissions from the burning of fossil fuels.
With the human population continuing to rise by 75 million or more per year and with torrid economic growth in much of the developing world, the burdens of deforestation, pollution, greenhouse gas emissions, species extinction, ocean acidification and other massive threats intensify.
Yet despite all the complexities, a firm and ever - growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.
In the time since the 2007 version of this report, the human effect on the climate has grown more than 40 percent stronger, thanks to continued emissions of greenhouse gases and more precision in measurements, with carbon dioxide leading the charge.
«In the face of natural variability and complexity, the consequences of change in any single factor, for example greenhouse gas emissions, can not readily be isolated, and prediction becomes difficult... Scientific uncertainties continue to limit our ability to make objective, quantitative determinations regarding the human role in recent climate change, or the degree and consequence of future change.»
Human behavioral changes, such as installing solar panels or investing in public transportation, alter greenhouse gas emissions, which change the global temperature and thus the frequency of extreme events, leading to new behaviors, and the cycle continues.
Terrell Johnson, reporting on a recent NASA publication concluding that deep ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science of climate change, it is the latest in a series of findings that show global warming to have slowed considerably during the 21st century, despite continued rapid growth in human - produced greenhouse gas emissions during the same time.»
Thus a grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming between 1 and 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.
Continued greenhouse gas emissions are likely to be associated with changes in rainfall patterns, desertification, more frequent storms and rises in sea level, all of which have implications for human movement.
And though, eventually, this drought will end, unless something is done about worldwide human greenhouse gas emissions, these kinds of extreme events will continue to recur and worsen.
Climate change is set to continue due to historically high greenhouse gas emissions by humans, according to the latest report by the Intergovernmental Panel on Climate Change.
The enhanced Greenhouse Effect we are now measuring is a human fingerprint because the source of it is the continued emission of greenhouse gases, primarily carbon dioxide, produced by industrialGreenhouse Effect we are now measuring is a human fingerprint because the source of it is the continued emission of greenhouse gases, primarily carbon dioxide, produced by industrialgreenhouse gases, primarily carbon dioxide, produced by industrial activity.
Yet despite all the complexities, a firm and ever - growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.
«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
Instead of including projections for extreme climate changes as a result of continued human emissions of greenhouse gases resulting from our production of energy, the high - end projections would have featured relatively modest changes and the low - end projections would have been completely unremarkable.
There are climate doomsday proponents and alleged «experts» who fear that Earth is warming so fast that it will soon reach hothouse Venus - like temperatures, primarily due to humans continuing global emissions of CO2, a trace greenhouse gas.
Researchers for the first time have calculated the highest tolerable «wet - bulb» temperature and found that this temperature could be exceeded for the first time in human history in future climate scenarios if greenhouse gas emissions continue unabated.
If present trends in the emission of greenhouse gases continue for 100 years, the group concludes, then resultant human - induced global warming will raise the Earth's average surface temperature between 1.4 and 5.8 degrees Celsius (2.5 and 10.4 degrees Fahrenheit).
These short - term cycles don't have long - term effects on the Earth's temperature, unlike the continuing upward trend caused by global warming from human greenhouse gas emissions.
So, in order to trigger another LIA, a new grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming of 1 to 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.
