Sunday set: Wildflower love

Alpine beauties

Some wildflower love from Austria spanning the last couple of months, from first sprouts emerging through the remnant muck of winter, to forest orchids. Check out the Summit Voice photo archives for more wildflower shots from around the world, and visit our online gallery to purchase fine art nature and landscape prints.

Many wildflower species are under the gun from climate change, especially in the mountains, where they will be pushed out of their habitat. Other studies have documented how global warming will affect native plant diversity in California. The changes to plant communities will ripple through ecosystems, affecting insect and birds, as many studies have shown.

Gradual CO2 buildup can trigger sudden climate tipping points

A new study links rising CO2 concentrations with disruptions to key climate-controlling currents during ice age climate shifts.

Ice age ocean current disruptions linked with greenhouse gas changes

Staff Report

Scientists say they’ve discovered another huge climate warning sign in the Arctic. Past increases in CO2 levels in the air drove ocean currents to a tipping point had a big impact on hemispheric weather patterns.

Within the span of just a few decades, rising CO2 concentrations drove temperatures in Greenland up by 10 degrees Celsius, according to a new study led by researchers with the Alfred Wegener Institute and the University of Cardiff.

Global warming puts sea turtles at risk

As temps warm, most eggs will produce females

Staff Report

Global warming was first identified as a potential threat to sea turtles in the 1980s because the temperature at which the eggs incubate helps determine the sex of the embryos. A new study now adds weight to those concerns, finding that  warmer temperatures could lead to higher numbers of female sea turtles and increased nest failure, negatively on the turtle population in some areas of the world.

Sunday set: In the garden

Tutti Frutti …

Seems like just yesterday it was snowing, and now you can eat ripe cherries off the trees, pluck strawberries in the fields and enjoy summer flowers in the fields. This weekend we spent a little time in the wine and forest country north of Danube and here’s what we found. Check out more Summit Voice travel photography in the Sunday Set archive for more travel pics, or head over to our online gallery at FineArt America for a full selection of nature and landscape photography.

E-cars could go mass-market by 2030, IEA says

Staff Report

Electric cars are likely to reach mass market adoption within the next decade, according to the International Energy Agency’s latest report on e-mobility. In 2016, the number of electric cars on the road globally reached 2 million, with China accounting for 40 percent of that total.

China has also deployed more than 200 million electric two-wheelers, as well as 300,000 elecric buses and leads the globe in electrification of the transport sector. China, the US and Europe made up the three main markets, totalling over 90 percent of all electric vehicles sold around the world.

Outside China, Norway is also moving ahead swiftly on electrification, with e-cars holding a 29 percent market share, the highest globally by far. The Netherlands is next, at 6.4 percent, followed by Sweden, at 3.4 percent. Continue reading “E-cars could go mass-market by 2030, IEA says”

Nevada restores solar net metering

New law provides more certainty for energy markets

Staff Report

Nevada’s shifting energy policy may be a microcosm of wider U.S. policy, as Gov. Bill Sandoval this week signed a bill that reinstates net metering for photovoltaic solar power systems.

The Nevada Public Utilities Commission eliminated net metering in late 2015, which created uncertainty in the renewable energy market. The new law reinstates a framework for owners of solar panels in the state to get reimbursed for excess energy they generate. Continue reading “Nevada restores solar net metering”

GOP launches new assault on public lands

Proposed bill would cut environmental reviews for massive clear cut logging and block access to environmental justice

Proposed legislation introduced by Republicans in Congress would open the door to widespread clearcutting without environmental reviews and black conservation advocates from seeking environmental justice in federal courts. @bberwyn photo.

Staff Report

Once again, Republican lawmakers in Congress are trying to roll back long-standing forest protections on a piecemeal basis, knowing that the public would never stand for a frontal assault on fundamental public lands environmental regulations.

The difference now is that they have an ally in the White House willing sign such measures, which makes resistance in the legislature even more critical. In the latest effort, U.S. Rep. Bruce Westerman (R-Ark.) reintroduced a measure that would allow logging projects on up to 30,000 acres — more than 46 square miles — of public land to proceed without meaningful public input, regardless of the environmental harms they might cause.
