What Time Magazine says means nothing. As I showed before, there were more publications made saying global warming is occurring versus global cooling. The media exaggerated and misinterpreted what the scientific journals/publications were discussing. Here is the explanation how the article came to be (with the original author of the article)

False, it was only one scientist that made that claim. Furthermore, they are referring to Ice Free
Summer, there is a big difference.

Never heard of Hansen, and just because
one scientist makes a claim (quite a bold claim too) doesn't mean everyone else in the field has the same view.
As far as I know, they did not specifically refer to the frequency of the events but the severity of the events. Which means stronger Hurricanes (as your link indicated) but not necessarily more (do remember that Cyclones and Typhons are also related). Forest fires have generally been increasing in occurrence (mostly in the Boreal Forests).
http://www.publish.csiro.au/?paper=WF09002 17 years in climate is nothing, we analyse trends in 30 year time frames to get a better view of the long term. It seems there still was an increase in temperature the past 30 years. Furthermore, current studies indicate the the world's oceans are one of the largest carbon sinks and temperature buffer (water has a high heat capacity) and evidence shows that the oceans absorbed considerable amount of thermal (heat) energy. Furthermore, within these years (17) there were considerable frequent La Niña events that are related to reducing global temperatures (not by much). Climate model tests were performed that ran with and without the effects of La Niña, the results indicated a continued rise in temperatures without La Niña but a stalled temperature increase with La Niña up to a certain time (they expect it to start rising again in the near future).
1880 - 2013 temperatures:

http://www.climate.gov/news-features/cl ... ast-decadeI went through a few of the papers listed there and it seems a few were misinterpreted. Examples:
Turner et al. 2014 - Late Holocene ecohydrological and carbon dynamics of a UK raised bog: impact of human activity and climate change: "Periods of high bog surface wetness correspond to the Wolf, Sporer and Maunder sunspot activity minima,
suggesting solar forcing was a significant driver of climate change over the last c. 1000 years.
Following the intensification of agriculture and industry over the last two centuries, the combined climatic and anthropogenic forcing effects become increasingly difficult to separate due to increases in atmospheric deposition of anthropogenically derived pollutants, fertilising compounds, and additions of wind-blown soil dust." So solar forcing was relevant in the past 1000 years, but not so much today due to anthropogenic causes.
Misios and Schmidt 2014 - The role of the oceans in shaping the tropospheric response to the 11 year solar cycle: "...
These findings suggest that changes at the ocean surface could contribute considerably to the poleward shift of the subtropical tropospheric jets, although a top-down influence on the oceans and hence indirectly on the jets cannot be excluded." The study they conducted was the effect of oceans on the subtropical tropospheric jets, not the 11 year solar cycle (they made models where the sun activity was constant).
Steinhilber and Beer 2013 - Prediction of solar activity for the next 500 years: Nothing about how the predicted sun activity will affect the Global Climate.
Gil-Alana et al. 2013 - Global temperatures and sunspot numbers. Are they related?: "
However, the fact that both series display poles in the spectrum at different frequencies implies that we fail to reject the null hypothesis of no relationship between the two variables in the long run. Moreover, assuming that the sunspots are exogenous, the results show no statistical significance of this variable on the global temperatures, which is one of the main contributions of the present work." They specifically say that there is no significance on the global temperatures.
Looks like the site did not properly read through the Publications... (I would read through more, but am limited with time.) So far, 4 out of 10 papers (going from top to bottom) being claimed to prove solar activity is the cause, either do not even compare solar activity with Climate Temperature or show opposing views of the site.
Climate Change is a large topic and there are still uncertainties. Though there are an increasing amount of studies indicating that Human action has an effect on the climate and ecosystems. That gasses such as CO2 and Methane do have an effect of increasing temperatures. The use of models are still not to be 100% trusted since there are still several uncertainties, though these are tools used to see how the future can play out and the need to plan ahead on how to address the scenarios. No scientist claimed that these models are absolute truth, just that they indicate a potential trend based on current knowledge.
