Unearthed new evidence (Mangerud and Svendsen, 2018) reveals that during the Early Holocene, when CO2 concentrations hovered around 260 ppm, “warmth-demanding species” were living in locations 1,000 km farther north of where they exist today in Arctic Svalbard, indicating that summer temperatures must have been about “6°C warmer than at present”.

  Proxy evidence from two other new papers suggests Svalbard’s Hinlopen Strait may have reached about 5 – 9°C warmer than 1955-2012 during the Early Holocene (Bartels et al., 2018), and Greenland may have been “4.0 to 7.0 °C warmer than modern [1952-2014]” between 10,000 and 8,000 years ago according to evidence found in rock formations at the bottom of ancient lakes (McFarlin et al., 2018).

A new study published in a peer-reviewed journal finds that climate models exaggerate the global warming from CO2 emissions by as much as 45%...

  In the study, authors Nic Lewis and Judith Curry looked at actual temperature records and compared them with climate change computer models. What they found is that the planet has shown itself to be far less sensitive to increases in CO2 than the climate models say. As a result, they say, the planet will warm less than the models predict, even if we continue pumping CO2 into the atmosphere.

Carbon dioxide emissions from industrial society have driven a huge growth in trees and other plants. A new study says that if the extra green leaves prompted by rising CO2 levels were laid in a carpet, it would cover twice the continental USA... The new study is published in the journal Nature Climate Change by a team of 32 authors from 24 institutions in eight countries.

  It is called Greening of the Earth and its Drivers, and it is based on data from the Modis and AVHRR instruments which have been carried on American satellites over the past 33 years. The sensors show significant greening of something between 25% and 50% of the Earth's vegetated land, which in turn is slowing the pace of climate change as the plants are drawing CO2 from the atmosphere.

  Nic Lewis, an independent scientist often critical of the IPCC, told BBC News: "The magnitude of the increase in vegetation appears to be considerably larger than suggested by previous studies."

The climate may be less sensitive to carbon dioxide than we thought – and temperature rises this century could be smaller than expected. That's the surprise result of a new analysis of the last ice age.

A paper published in the Journal of Climate finds from 800,000 observations a significant decrease in longwave infrared radiation from increasing greenhouse gases over the 14 year period 1996-2010 in the US Great Plains. CO2 levels increased ~7% over this period and according to AGW theory, downwelling IR should have instead increased over this period.

The findings contradict the main tenet of AGW theory which states increasing greenhouse gases including the primary greenhouse gas water vapor and clouds will cause an increase of downwelling longwave infrared “back-radiation.”

A group of top NASA boffins says that current climate models predicting global warming are far too gloomy, and have failed to properly account for an important cooling factor which will come into play as CO2 levels rise.

Several climate models indicate that in a 2 × CO2 environment, temperature and precipitation would increase and runoff would increase faster than precipitation. These models, however, did not allow the vegetation to increase its leaf density as a response to the physiological effects of increased CO2 and consequent changes in climate.

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles... Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon dioxide might influence climate; but up to now there was no evidence from submarine volcanoes. The findings suggest that models of earth’s natural climate dynamics, and by extension human-influenced climate change, may have to be adjusted.

Tropical forests are growing faster than scientists thought due to rising levels of carbon dioxide in the atmosphere. A Nasa-led study has found that tropical forests are absorbing 1.5 billion tons of carbon dioxide every year as they photosynthesise and grow. But this new study suggests the tropical forests are using far more of the carbon, and so growing far faster than previously believed... Scientists previously believed tropical forests emitted carbon dioxide

A fairly aggressive strategy to reduce carbon dioxide emissions under current reduction scenarios "does little to mitigate warming over the next 20 to 30 years," the study said. With carbon dioxide reductions alone, global temperatures are still projected to rise by more than 2 degrees Celsius by 2050 over pre-industrial levels.

An analytical chemist who works in spectroscopy and atmospheric sensing, Michael J. Myers of Hilton Head, S. C., declared, "Man-made global warming is junk science," explaining that worldwide manmade CO2 emission each year "equals about 0.0168% of the atmosphere's CO2 concentration ... This results in a 0.00064% increase in the absorption of the sun's radiation. This is an insignificantly small number."

The reported killing of 23 Honduran farmers in a dispute with the owners of UN-accredited palm oil plantations has called into question the integrity of the EU's emission trading scheme (ETS), as carbon credits from the plantations remain on sale. In Brussels, Green MEP Bas Eickhout called the alleged human rights abuses "a disgrace", and told EurActiv he would be pushing the European Commission to bar carbon credits from the plantations from being traded under the ETS.
