Earlier studies had documented little change in the western Ross coastline prior to 1995, and the new study both confirmed the earlier work and extended the analysis to the present time.
This work underscores the complexity of Antarctic climate change and glacier response.

Prof. Quansheng Ge and his group from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, collected a large number of proxies and reconstructed a 2000-year temperature series in China with a 10-year resolution, enabling them to quantitatively reveal the characteristics of temperature change in China over a common era.

Since 1600, 278,880 people have been killed by volcanic activity, with many of these deaths attributed to secondary hazards associated with the main eruption. Starvation killed 92,000 following the 1815 Tambora eruption in Indonesia, for example, and a volcanic tsunami killed 36,000 following the 1883 Krakatoa eruption.
Research shows that volcanic activity has shown no let up since the turn of the 21st century – it just hasn’t been around population centres. Indeed, there remain a number of volcanoes poised to blow which pose a major threat to life and livelihood.

So… If climate change caused the Vikings to turn their plowshares into swords, abandoning their farms to become terrorists… the climate change would have been of the warming variety. I’m not a farmer, but it seems to me that global warming would have actually enhanced the Vikings’ ability to farm up around the Arctic Circle.

In the mid-1990s thermometers changed right across Australia — new electronic sensors were installed nearly everywhere. Known as automatic weather sensors (AWS) these are quite different to the old “liquid in glass” type.
The electronic ones can pick up very short bursts of heat—so they can measure extremes of temperatures that the old mercury or liquid thermometers would not pick up unless the spike of heat lasted for a few minutes.
It is difficult (impossible) to believe that across the whole temperature range that these two different instruments would always behave in the exact same way.

Finally, we’ve been told for years that volcanic eruptions cause COOLING … although what cooling is visible in the historical record is generally local, small, and short-lasting. But now, they say eruptions cause Northern Hemisphere winter warming? What’s up with that?

An article just published in the Proceedings of the Royal Society B describes two remarkably different hydrothermal vent fields discovered in the southern Gulf of California. Despite being relatively close together, these vents host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities. Instead, the new paper suggests that local geology and the chemistry of the vent fluids are important factors affecting vent communities

Recorded temperatures at the Bureau of Meteorology’s Thredbo Top automatic weather station have dropped below -10C in the past week, after action was taken to make the facility “fit for purpose”.
A record of the Thredbo Top station for 3am on Wednesday shows a temperature reading of -10.6C. This compares with the BoM’s monthly highlights for June and July, both showing a low of -9.6C.
The BoM said it had taken immediate action to replace the Thredbo station after concerns were raised that very low temperatures were not making it onto the official record.

Detailed pattern correlation of Earth’s temperature changes during the past 450 kyrs reveals observations about several cyclic climate patterns. The past four glacial cycles are increasing in duration from 89 kyrs to 119 kyrs. Within these glacial cycles, two warm periods occur about 200 kyrs apart and have strikingly similar temperature characteristics.
During the last 450 kyrs, the five major warm onsets with rapidly increasing temperatures are triggered by increases in the eccentricity, obliquity, and precession of Earth’s orbit. The nearly concurrent increase in these three astronomical forces appears a necessary component for a major warm onset. Obliquity is the dominate control for ending these major warm periods and entering a cooling phase.

As noted in my article four years ago, Japan has a program for producing natural gas from methane hydrates located near its coast, and predicts it will be successful by 2019.
Most people believe that Japan’s objective is highly optimistic, but it does shed light on the efforts currently underway to develop the technology for extracting natural gas from methane hydrates.

We provide a new confirmation for the link between solar activity and climate cycles by wavelet analysis showing a remarkably good agreement of the power of the ~190 – year period for temperatures and solar activity over 9000 years (see Fig.4. lower panel). As (Fig.2 and Table 2 ) show, the periods of ~1000 and ~460 years are also apparently common in records of temperatures and cosmogenic nuclides.

And what did these analyses reveal?
Not surprisingly, when all was said and done, the authors report that “increasing [the] CO2 concentration to 3000 ppm at 35°C did not cause changes in any of the measured responses.” They did note, however, that the heart rates of the subjects were slightly reduced under elevated CO2 conditions (Figure 1, top left panel), although these reductions were not statistically significant.

Since 1988, a mere 100 companies have been responsible for 71 percent of the entire world’s industrial greenhouse gas emissions.
This data comes from an inaugural report published by the Carbon Disclosure Project (CDP), an environmental non-profit. Charting the rapid expansion of the fossil fuel industry in the last 28 years, they have now released some truly staggering numbers on the world’s major carbon polluters.

Today ‘warm’ is strongly connected with ‘climate change’, if not with ‘dangerous climate change’. In the minds of people ‘cold’ should be more stable. But, paleo data show that it is‘cold’ that is unstable. While ‘warm’ always shows a high stability in climatic conditions.

Weathering of Earth by glaciers may have warmed the planet over eons by aiding the release of carbon dioxide into the atmosphere. A new study shows the cumulative effect may have created negative feedback that prevented runaway glaciation.

The purpose of this study is to present robust evidence that the sun is working with water vapour to control the Earth’s climate and to show that the influence of CO2 on atmospheric temperature is so small as to be negligible.

The chart below is taken directly from figures provided by the U.S. government’s Carbon Dioxide Information Analysis Center (CDIAC) website, specifically its 2016 Global Carbon Project spreadsheet on the Historical Budget tab. In terms of gigatons of carbon, and from 1770 to 2004, it itemizes the growth rate of radiative forcing by atmospheric CO2 and the growth rate of oceanic absorption, what is known as a “carbon sink.”

Corals have a little thermometer built in them, when you take a core of them from many years ago we know what the temperature of the water was back when Captain Cook sailed up the coast, it was actually about the same temperature then. It was colder 100 years ago, but it has recovered from that. The temperatures on the reef are not even significantly warmer than average on a hundred year timescale.

We present a decadal-centennial scale Holocene climate record based on trace elements contents from a 65 cm stalagmite (“Père Noël”) from Belgian Père Noël cave. Père Noël (PN) stalagmite covers the last 12.7 ka according to U/Th dating. High spatial resolution measurements of trace elements (Sr, Ba, Mg and Al) were done by Laser- Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). Trace elements profiles were interpreted as environmental and climate changes in the Han-sur-Lesse region.

The New York Times said yesterday that heatwaves in the past were “virtually unheard of in the 1950s”, temperatures approaching 130 degrees didn’t used to occur, and summer temperatures have shifted towards more extreme heat.
(…) Every single claim in the article is patently false, and the exact opposite of reality. The authors intentionally started their study in a cold period, after the extreme heat of the 1930’s.
