New Mexico’s public education secretary looks to deny global warming, evolution
New Mexico’s public education secretary, Christopher Ruszkowski, is defending , evolution and the age of the earth.
State education officials are holding their one and only public hearing Monday to gather comments on the proposed standards.
In a public message published Sunday, Public Education Secretary Christopher Ruszkowski says the new standards will give teachers and families flexibility and local control around science materials, curriculum and content. He did not specifically address how the standards address the teaching of evolution and climate change.
Ruszkowski’s idea is in contrast to firm scientific evidence on both counts. (EDITORIAL NOTE: Christopher Ruszkowski is far from a person interested in the education of New Mexico’s children. he pushes a Republican, no-factual based idea as one that wil “alllow parents a choice”. In reality it is simply a step back toward the dark ages).
Scientific evidence for warming of the climate system is unequivocal. – Intergovernmental Panel on Climate Change
The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1
Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.
The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.
Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.
The evidence for rapid climate change is compelling:
Global temperature rise
The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.5 Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months. 6 + more Earth’s vital signs: Global temperature An indicator of current global average temperature as measured by NASA; updated monthly.

Shrinking ice sheets
The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.

Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.11, 12 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans.

The fact of evolution is the most fundamental issue and the one established with utmost certainty. During the nineteenth century, Charles Darwin (1809–1882) gathered much evidence in its support, but the evidence has accumulated continuously ever since, derived from all biological disciplines. The evolutionary origin of organisms is today a scientific conclusion established with the kind of certainty attributable to such scientific concepts as the roundness of the Earth, the motions of the planets, and the molecular composition of matter. This degree of certainty beyond reasonable doubt is what is implied when biologists say that evolution is a fact ; the evolutionary origin of organisms is accepted by virtually every biologist.
The mechanisms of evolution operate at the genomic level. Changes in DNA sequences affect the composition and expression of our genes, the basic units of inheritance. To understand how different species have evolved we have to look at the DNA sequences in their genomes. Our evolutionary history is written into our genome. The human genome looks the way it does because of all the genetic changes that affected our ancestors. When DNA and genes in different species look very similar, this is usually taken as evidence of them sharing ancestors. For example, humans and the fruit fly, Drosophila melanogaster, share much of their DNA. 75 per cent of genes that cause diseases in humans are also found in the fruit fly. DNA accumulates changes over time. Some of these changes can be beneficial, and provide a selective advantage for an organism. Other changes may be harmful if they affect an important, everyday function. As a result some genes do not change much. They are said to be conserved.
Different types of evolution
When the same adaptations evolve independently, under similar selection pressures. For example, flying insects, birds and bats have all evolved the ability to fly, but independently of each other.
When two species or groups of species have evolved alongside each other where one adapts to changes in the other. For example, flowering plants and pollinating insects such as bees.
When a species splits into a number of new forms when a change in the environment makes new resources available or creates new environmental challenges. For example, finches on the Galapagos Islands have developed different shaped beaks to take advantage of the different kinds of food available on different islands.
