Though the Intergovernmental Panel on Climate Change (IPCC) has asked science journalists and political writers wearing a scientific beard to not attribute every weather event to climate change, it is still common to have every storm, drought and temperature to be listed as proof of climate change.

But that isn't science.  Scientists at the California Institute of Technology (Caltech) and ETH Zurich have instead shown that global warming actually tends to reduce temperature variability.

Australia’s CSIRO has come up with some pretty amazing inventions over the past 86 years of research, from polymer banknotes to insect repellent and the world-changing Wi-Fi. But we can also lay claim to something a little more esoteric – we actually invented a whole new word.

It is well established that particles emitted during major volcanic eruptions cool the atmosphere for two or three years  due to a 'parasol' effect that reflects sunlight.
A new study finds that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments may ramp up production.

Though methane stays in the atmosphere for far less time than CO2, it is 25X more potent during that period. Concerns about methane have risen because of concerns about possible leaks due to increased natural gas, which produces far less CO2 than coal, and that methane may be released as climate changes.
A new paper notes that the Campanian Ignimbrite eruption in Italy 40,000 years ago, one of the largest volcanic cataclysms in Europe and responsible for injecting a significant amount of sulfur-dioxide (SO2) into the stratosphere, coincided with the final decline of Neanderthals as well as with dramatic territorial and cultural advances among modern humans.  

Scientists have long debated if this eruption and the resulting volcanic sulfur cooling and acid deposition could have contributed to the final extinction of the Neanderthals more than climate change or hominin competition. 

A new paper tests this hypothesis using a climate model. 
A new study looked at the pattern of variation of the South Asian monsoon over time and compared it with the evolution of African mole rats and bamboo rats by evolutionary distribution in space and through time and found that weakening and strengthening monsoon rains played a key role in the evolution of these species.

Over a period of 24 million years, the changes observed in the teeth and head shape of the rodents examined, matched the varying strength of the monsoon.

Of the 38 species studied, six still exist today and the changing rains seem to have driven several species into extinction.

Nature is out to kill us, as always.

Every day around the world, lightning strikes the ground about 10 times per second. That's nearly one million strikes a day!

In the U.S. there are 20 million strikes on average every year, and now David Romps, an atmospheric scientist at the University of California Berkeley, says we can expect to see that number grow in the coming years.

“What we find by looking in the climate models is that on average they’re predicting a 50 percent increase in the amount of lightning that you get in the United States, during this century, the 21st century," said Romps.

And the cause?

We may idealize the last century but natural forces have always caused climate on Earth to fluctuate - sometimes quite a bit. But science is about controlling nature and not letting random behavior control our destinies and since we know that some periods were good and some awful, we'd like to avoid the awful.

We can't control everything - the earth is still going to orbit the sun and such orbital forcing of climate change happens over thousands of years and brings ice ages and warming periods. 
The activity of the Sun is an important factor in the complex interactions that control our climate. We don't really even understand the impacr of the sun - it is not constant over time, but has greater significance when the Earth is cooler, according to a new paper in Geology.

There has been discussion as to whether variations in the strength of the Sun have played a role in triggering climate change in the past, but more and more research results clearly indicate that solar activity - i.e. the amount of radiation coming from the Sun - has an impact on how the climate varies over time.
The recent slowdown in climate warming is due to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system. They do not signal any slowdown in human-caused global warming. 

The Atlantic Multidecadal Oscillation (AMO) describes how North Atlantic sea-surface temperatures tend to oscillate with a periodicity of about 50 to 70 years. The Pacific Decadal Oscillation (PDO) varies over a broader range of timescales. The researchers looked only at the portion of the PDO that was multidecadal -- what they term the Pacific multidecadal oscillation (PMO).
