When the Lights Went On: Earliest Quasar Shines Light on Universe's Early galaxy formation




Deepest Space, Earliest Times

When the Lights Went On

Plasma-spewing quasar shines light on universe's youth, early galaxy formation,
Carnegie Institution for Science, July 9, 2018.

"Quasars are comprised of enormous black holes accreting matter at the centers of massive galaxies."

"...this newly discovered quasar's light has been traveling nearly 13 billion of the universe's 13.7 billion years to reach us here in Earth. P352-15 is the first quasar with clear evidence of radio jets seen within the first billion years of the universe's history."

"The Big Bang started the universe as a hot soup of extremely energetic particles that were rapidly expanding. As it expanded, it cooled and coalesced into neutral hydrogen gas, which left the universe dark, without any luminous sources, until gravity condensed matter into the first stars and galaxies."

Watch Out for the Green Water: Blue-Green Algae News and Safety Information

Watch Out for the Green Water

 Do not drink, or allow your animals or children to drink from or play in water containing cynobacteria, otherwise known as toxic blue-green algae. Review the Blue-Green News just below and the safety information at the bottom of this page:

Blue-Green Algae Safety and Identification Information


July 2018,
August 2015:
Rising heat and declining waters are creating conditions even more favorable for cynobacteria,otherwise known as toxic blue-green algae.

In the Sierra the source of nitrogen feeding the blue-greens is cattle grazing. This is the same grazing that preserves High Sierra meadows, and for which the series of check dams that gave birth to countless lakes were created.

Climate Models Underestimating Scale of Change: Twice What Climate Models Predict?



Climate Models Underestimating Scale of Change

Global warming may be twice what climate models predict,
University of New South Wales, July 4, 2018.

Anyone reading this site for any length of time already knows that the "standard" climate models are at least suppressing expected Carbon increases by half, while not accurately accounting for current observed atmospheric and oceanic changes.
The more "pessimistic" climate models are proving to be the "best-fits" for the real behavior of the atmosphere and oceans we are observing and experiencing. Check the links to previous analysis of climate models below.


This Research

"Future global warming may eventually be twice as warm as projected by climate models under business-as-usual scenarios and even if the world meets the 2°C target sea levels may rise six metres or more..."

“Observations of past warming periods suggest that a number of amplifying mechanisms, which are poorly represented in climate models, increase long-term warming beyond climate model projections."
