Shelf sediments reveal climate shifts through the eons

by University of Queensland, May 10, 2017, in DailyScience


Ms Korpanty said global climate underwent significant change about 14 million years ago when the Antarctic ice sheet expanded.

“The new study presents shallow-marine sediment records from the Australian continental shelf, providing the first empirical evidence linking high-altitude cooling around Antarctica to climate change in the subtropics during the Miocene era,” she said.

Earth’s forests just grew 9% in a new satellite survey

The Age of Exploration may be long past, but even in the 21st century, our maps can still get a major update. Using satellite imagery, a new study has found hidden forests all over the world—almost enough for a second Amazon—in areas with little moisture known as drylands.

 


A new estimate of dryland forests suggests that the global forest cover is at least 9 percent higher than previously thought. The finding will help reduce uncertainties surrounding terrestrial carbon sink estimates.

Dr. Fred Singer on ‘Global Warming Surprises’

by Fred Singer, May 11, 2017


Temp data in dispute can reverse conclusions about human influence on climate.

Exploring some of the intricacies of GW [Global Warming] science can lead to surprising results that have major consequences. In a recent invited talk at the Heartland Institute’s ICCC-12 [Twelfth International Conference on Climate Change], I investigated three important topics:

1. Inconsistencies in the surface temperature record.

2. Their explanation as artifacts arising from the misuse of data.

3. Thereby explaining the failure of IPCC to find credible evidence for anthropogenic global warming (AGW).
