Not exact matches

If the exercise work rate is free to vary, then experimental interventions such as changes in ambient temperature, oxygen content of the inspired air, energy substrate availability or the provision of incorrect distance feedback all alter the power output (pacing strategy), whereas the rate of increase in RPE has been found to be similar between conditions.13 20 21 24 — 26

For example, the ice ages during the last several million years — and the warmer periods in between — appear to have been triggered by no more than a different seasonal and latitudinal distribution of the solar energy absorbed by the Earth, not by a change in output from the sun.

The MLTI region is important because it is very sensitive to changes in the Sun's energy output as well as human activities that affect the atmosphere.

Our Sun is a relatively stable star, but changes in solar energy output, such as during massive solar flares, can still have an impact.

Thanks for publishing this, there are folks who denigrated the work of scientists that claimed a solar - climate (temperature) link because the variability in solar energy output just wasn't enough to explain the temperature swings, and perhaps they now realize that there could be another mechanism - similar to a transistor where small changes in gate voltage can affect large changes in power transmission - whereby solar activity can create significant effects on temperature.

Like the Port Talbot Steelworks (though by reducing the dead time in the efficiency changes, they increased output for less energy costs).

Changes in the sun can of course affect the amount of energy received by the earth through changes in its output, variations in the intensity of UV - light, or perhaps even clouds through galactic cosmiChanges in the sun can of course affect the amount of energy received by the earth through changes in its output, variations in the intensity of UV - light, or perhaps even clouds through galactic cosmichanges in its output, variations in the intensity of UV - light, or perhaps even clouds through galactic cosmic rays.

Funny thing is, the energy involved in these solar changes is a really, really small fraction of the total solar output.

However, nobody could come up with a good explanation for how the slight changes in solar energy output could change climate so much.

With wind forecasting, changes in wind energy output are factored into grid operations much like variations in demand — both change over a matter of 30 minutes or even hours (not a matter of seconds, such as when fossil - fuelled or nuclear plants experience an unexpected outage, or a tree falls on a transmission line).

«Something very different was happening during the 17th Century, and it produced a much more permanent change in the Sun's energy output at that time,» Rottman said.

The models currently assume a generally static global energy budget with relatively little internal system variability so that measurable changes in the various input and output components can only occur from external forcing agents such as changes in the CO2 content of the air caused by human emissions or perhaps temporary after effects from volcanic eruptions, meteorite strikes or significant changes in solar power output.

Appreciable changes in climate are the result of changes in the energy balance of the Earth, which requires «external» forcings, such as changes in solar output, albedo, and atmospheric greenhouse gases.

Science: Climate changes in the past suggest that our climate reacts to energy input and output, such that if the planet accumulates more heat than it gives off global temperatures will rise.

The sooner extremist can be put in their box and everyone else can converge on the sensible «Lomberg» view that climate change is a problem best solved by many $ billions on energy research, not $ trillions of lost output, the better.

Because the amount of electrical energy produced by a wind turbine varies nonlinearly with wind speed, small changes in wind speed can result in much larger changes in output.

Time - of - use (TOU) rates, even without net energy metering, could change the value proposition in places like California and Texas because solar output is «so in line with peak pricing, especially during those late afternoon summer hours,» he said.

It's also changes in the solar wind and interplanetary magnetic field, which cycles along with energy output and shields the earth from galactic cosmic rays.

Despite their high energies, flares are minuscule compared to the entire energy output of the Sun, and thus cause very little change in TSI.

Was it attributed to a step change in the Suns energy output or some other phenomena (maybe the 70 ′ s energy crisis...)?

For example, a recent slowing in the rate of surface air temperature rise appears to be related to cyclic changes in the oceans and in the sun's energy output, as well as a series of small volcanic eruptions and other factors.

The only thing that I would contend could be added would be long slow cumulative changes in solar output other than raw TSI namely changes in the mix of particles and wavelengths over longer periods of time such as MWP to LIA to date and which seem to have some effect on surface pressure distribution and global albedo so as to alter solar shortwave into the oceans and thus affecting the energy available to the ENSO process.

However, there has been a significant amount of research conducted since then to show that variations in the Sun's energy output have an impact on changes in Earth's climate.

Over the last 50 years, solar variations have resulted in less than a.1 % change in solar energy output.

Since such models can not account for the climate system's apparent sensitivity to small perturbations in solar energy apparently brought about by the very long term changes in the Earth's orbit about the Sun, they may also underestimate climate sensitivity to energy output fluctuations caused by solar activity, even during the eleven - year Schwabe cycle.

Nothing in recorded history suggests solar energy output will change drastically enough in the foreseeable future to overwhelm the impact humanity's massive input of greenhouse gases is having on our world.

As they stand at present the models assume a generally static global energy budget with relatively little internal system variability so that measurable changes in the various input and output components can only occur from external forcing agents such as changes in the CO2 content of the air caused by human emissions or perhaps temporary after effects from volcanic eruptions, meteorite strikes or significant changes in solar power output.

... re my last comment — interesting point, the actual change in kinetic energy dissipation in the area of the wind farm was a small fraction of the energy output of the wind farm, because much of that energy would otherwise have been dissipated by land cover.

We need to figure out how to storage that energy so that we don't need to keep natural gas power plants spinning as backup in case there's an unforeseen change in wind power output, or to pick up the slack on days when there's simply no wind.

The observed pattern is not consistent with purely natural changes in the Sun's energy output, volcanic activity, or natural climate variations such as El Niño and La Niña.

Changes in solar output influence how much of the sun's energy the Earth's surface receives as a whole; more or less solar energy means warmer or cooler global climate.

While the Earth's atmosphere has seen higher levels of carbon dioxide than it does now, as well as higher temperatures and far greater sea levels, those instances were due to natural drivers of climate change, such as periodic variations in the planet's orbit and in solar energy output.
