Sentences with phrase «like changes in solar activity»

Not exact matches

A more reasonable natural variability / forcing argument might go something like this: 1) There is natural variability of climate due to solar activity 2) Climate is changing now 3) Forcing can result in climate change, but the response of the C cycle to forcing is poorly understood 4) Forcing is happening now 5) Forcing and / or solar activity could be to blame for current warming trends Is this unreasonable?

All evidence suggests that significant climate changes like the LIA, and the Medieval Warm Period that preceded it, are the result of significant changes in solar activity.

The red line incorporates natural influences like changes in solar output and volcanic activity but virtually all of the long - term warming is attributable to human - caused increases in greenhouse gasses.

It is astounding that dangerous man - made global warming fanatics like Obama and Prince Charles, in addition to all those climate change charlatans at various academies of science such as The Royal Society, prefer to ignore real word observational data on climate and solar activity, in favour of psuedo - science and climate models that consistently have failed in their scenarios and projections.

«There's that odd cyclical behavior in Holgate's sea level change rate plots, which looks remarkably like it's in phase with solar activity.»

Long - term trends and changes (longer than solar cycle) can partly be caused by long - term changes of trend drivers of solar / space weather origin like geomagnetic activity, which in terms of the aa - index was increasing over almost the whole 20th century (e.g., Mursula & Martini 2006), even though now it is low.

There is a solid body of research now showing that any apparent slow - down of warming during the past decade was likely due to natural short - term factors (like small changes in solar output and volcanic activity) and internal fluctuations related to e.g. the El Niño phenomenon.

http://www.agci.org/docs/lean.pdf «Global (and regional) surface temperature fluctuations in the past 120 years reflect, as in the space era, a combination of solar, volcanic, ENSO, and anthropogenic influences, with relative contributions shown in Figure 6.22 The adopted solar brightness changes in this scenario are based on a solar surface flux transport model; although long - term changes are «50 % larger than the 11 - year irradiance cycle, they are significantly smaller than the original estimates based on variations in Sun - like stars and geomagnetic activity.

The term «radiative forcing» refers to a global energy imbalance on Earth, which may be caused by various effects like changes in the greenhouse effect or solar activity.
