Climate: What’s up, El Niño?

dfgh

A NOAA map shows warmer than average ocean temperatures in red developing off the coast of South American during the past few months, but sea surface temps are also remaining warmer than average across the western Pacific, hampering development of a full-fledged El Niño.

Widespread ocean warmth may hamper development

Staff Report

FRISCO — This year’s brewing El Niño may be dampened by widespread warm sea surface temperatures across the Pacific Ocean, according to weather experts. Specifically, ocean temperatures across the far western Pacific have remained so warm that one of the key ingredients for a full-strength El Niño is missing — a significant difference in temperatures between the western and Eastern Pacific.

But so far this summer, warmer than average temperatures are spread across the Pacific from east to west. Just last week, the National Climatic Data Center announced that the average global temperature for June was the warmest on record, driving in large part by warm oceans. Continue reading

New model can resolve some climate impacts on a regional scale

STAFF REPORT

FRISCO — Increasing concentrations of greenhouse gases and ozone depletion over Antarctica are the main drivers of the long-term decline in rainfall over southwestern Australia, federal scientists said in a weekend press release.

The findings, published in Nature Geoscience, are derived from a new  high-resolution climate model that may help researchers identify more links between heat-trapping gases and regional climate trends, including here in the U.S. Continue reading

Climate: Global temps hit new May record

Year to-date is fifth-warmest through May

FRISCO — The average global temperature soared to a new record in May, more than 1.3 degrees Fahrenheit above the 20th century average, according to the latest monthly update from the National Climatic Data Center.

Land surface temperatures were well above average in many parts of the world, including Australia and Alaska, but sea surface temperatures were off the charts, driving the global average temperature for the month to an all-time high. Continue reading

Staff Report

FRISCO — Federal climate experts this week confirmed what a lot of people already knew instinctively — a long, cold winter stretched well into March in many parts of the country, with the average monthly temperature for the month coming in at 1 degree Fahrenheit below the 20th century average.

Across the country, there were five times as many record cold daily maximum and minimum temperatures (5822) as record warm daily maximum and minimum temperatures (1149) — an anomaly in an era when warm temperature records have consistently outnumbered cold records for months and years at a time.

FRISCO — The average global temperature for January 2014 was 1.17 degrees Fahrenheit above the 20th century average — the fourth-highest for Planet Earth, with record-high readings reported from southeastern Brazil and central and southern Africa. Land surface readings in the southern hemisphere were record warm and record warmth was also reported in the North Pacific. Continue reading

Oceans: NOAA report offers guides for sustainable aquaculture

Fish farms can be operated sustainably with good planning and best management practices, according to NOAA.

Good safeguards can help minimize environmental impacts

By Summit Voice

FRISCO — Despite reported environmental problems reported with existing aquaculture operations, federal scientists say coastal fish farming can be done minimal or no harm to the coastal ocean environment.

The new report by researchers at NOAA’s National Ocean Service finds that water quality impacts are limited to slightly raised levels of nitrogen and phosphorus within a few hundred feet of aquaculture facilites, but that impacts can be limited with good planning and environmental safeguards.
