Climate pledge includes a 2026 peak for emissions

Staff Report

FRISCO — Climate activists today hailed Mexico’s commitment to reduce greenhouse gas emissions as an important milestone leading up to a hoped-for global climate deal later this year.

On the path to that agreement, a March 31 deadline looms for individual countries to make their emissions reductions targets known, and Mexico became the first emerging economy to commit to reducing greenhouse gases after 2020. Read Mexico’s pledge here. Continue reading

Oceans: Proposed gillnet ban may be too little, too late for critically endangered Gulf of California vaquitas

Lack of enforcement seen as stumbling block to recovery

Staff Report

FRISCO — Mexico has launched a last-ditch effort to protect the critically endangered vaquita porpoise by banning the use of gillnets in the northern Gulf of California. Conservation advocates said the ban is a step in the right direction, but expressed concern that Mexico won’t follow through with enforcement.

Vaquitas, the smallest members of the porpoise family, live only in the northern Gulf of California, generally in the vicinity of the Colorado River delta. The species has been on the Endangered Species List since 1985. Scientists say less than 100 individuals remain. Vaquitas could be extinct by 2018 without drastic conservation and recovery actions.

According to conservation biologists, the biggest threat by far to vaquitas is drowning in fishing nets. Environmental pollution, habitat degradation and inbreeding are also factors in their decline. Continue reading

Mexico – U.S. deal a hopeful sign for the Colorado River

This icy trickle of water in North Tenmile Creek has a better chance of making it to the Gulf of California, thanks to a new agreement between the U.S. and Mexico on Colorado River flows.

Temporary treaty amendment includes innovative water banking

By Summit Voice

FRISCO — A landmark  water agreement between the U.S. and Mexico on Colorado River flows is winning acclaim as a true win-win — a rarity in an era of perpetual water shortages and rising concerns over allocation of the Southwest’s great river.

But even though the deal is getting good reviews, it’s important to remember that the Colorado River is not healthy.

Massive diversions and storage projects have choked off native flows that helped maintain riparian habitat. Those same projects have pushed four native fish species to the brink of extinction. The agreement will help resolve some long-standing issues in the lower Colorado Basin, but doesn’t do anything to alleviate the extreme pressure on the river’s upper reaches. Continue reading

Hurricane Miriam headed toward Baja

Major Pacific storm with winds of 120 mph expected to weaken before reaching Baja coast

SUMMIT COUNTY — One of the strongest hurricanes of the year has formed in the eastern Pacific and could affect the weather in the southwestern U.S. late in the week, according to the National Hurricane Center.

Hurricane Miriam, southwest of the Baja Peninsula, is generating sustained winds of 120 mph and could strengthen a bit more in the next couple of days before weakening as it encounters strong winds from the west.

The storm is forecast to track northward, and even northeastward, which would put the system on track for a landfall along the Baja coast next weekend or early next week, potentially with tropical storm force winds.

Miriam’s outflow is already streaming over the southern tip of Baja. No coastal watches or warning have  been issued for the storm, but the system will likely soon pump up the surf along the Baja Coast.

Maya may have intensified drought by clearing forests

Clear-cutting may have reduced rainfall by as much as 15 percent

By Summit Voice

SUMMIT COUNTY — The decline of Maya civilization has often been linked with drought by climate researchers and archaeologists. Now, a new study suggests the Maya may have hastened their own demise by clearing forests.

Based on climate modeling, Mayan land-clearing may have reduced rainfall by as much as 15 percent in the heavily logged Yucatan Peninsula, and by up to 5 percent in other parts of southern Mexico. Overall, the researchers said as much as 60 percent of the regional drying may have been caused by deforestation.

“We’re not saying deforestation explains the entire drought, but it does explain a substantial portion of the overall drying that is thought to have occurred,” said the study’s lead author Benjamin Cook, a climate modeler at Columbia University’s Lamont-Doherty Earth Observatory and the NASA Goddard Institute for Space Studies.

Watchdog group says border wall plans are flawed

Flooding a concern along the Rio Grande

Along the Rio Grande …

By Summit Voice

It appears that the U.S. has not learned from recent Eastern European history that walls and fences just don’t work when it comes to trying to keep people in or out of a country.

Pushed mostly by politicians with a xenophobic agenda and pandering to a xenophobic constituency, plans for a massive border wall along the Rio Grande continue, and now, it appears as though the new 14-mile section of wall could  block flood water from draining into the Rio Grande, bottling it up in towns and farm land and significantly worsening damage inflicted, according to Public Employees for Environmental Responsibility.

The three border wall sections will consist of concrete bollards spaced four inches apart and topped by as much as 15 feet of steel fencing. If the bollards become choked with storm debris, the structures will function as dams, deflecting water out of the river channel and perhaps even changing the channel of the River itself (and thus our border).  The wall sections are slated to be placed in the Rio Grande floodplain adjacent to the communities of Roma, Rio Grande City and Los Ebanos.

Hurricane Carlotta nears Mexico coast with 80 mph winds

Storm surge, mountain floods and mudslides expected

Hurricane Carlotta, far left, is growing and strengthening rapidly near the southern coast of Mexico.

Hurricane Carlotta could move along the coast of southern Mexico the next few days.

By Summit Voice

SUMMIT COUNTY — Hurricane  warnings are in effect for several hundred miles along the Pacific coast of Mexico including Acapulco, as Hurricane Carlotta approaches the area with winds that could reach 100 mph early in the weekend.

The biggest concerns are for a dangerous storm surge that will produce significant coastal flooding, along with powerful and destructive waves. Rainfall totals are forecast to reach 3 to 5 inches in Chiapas and northern Oaxaca, with higher amounts up 10 15 inches in the mountains of southern Oaxaca, where mudslides and flash flooding are possible.

The latest forecast track nudges Carlotta a bit farther north before the hurricane turns west again, which means the storm could weaken and even fall apart if it runs into the high mountains of southern Mexico, but the exact track has been hard to pinpoint. Carlotta could rake a large part of Mexico’s southern coast with high winds and heavy rains.

Officially, wind speeds are forecast to reach 90 mph by Friday evening and 100 mph by Saturday morning as the center nears the coast.
