The world’s smallest porpoise – the vaquita – is in real trouble. According to a recent report by the International Committee for the Recovery of the Vaquita (or CIRVA), the vaquita population has plummeted to just 30 individuals –a 90% plunge since 2011 – despite international conservation efforts. The vaquita, which is found only in Mexico’s Upper Gulf of California, is the most endangered marine mammal on Earth and is on the doorstep of extinction.
Back in 2011, utility-scale solar power cost a little over $4 per watt on average. In February of that year, former Energy Secretary Steven Chu announced the SunShot initiative, which had the goal of reducing the total cost of photovoltaic systems by 75% to the target value of $1 a watt by the year 2020.
Because of its Arctic location, Alaska is warming about twice as fast as the rest of the United States. The past year has been the warmest on record. The forces of erosion and increasingly powerful storms have resulted in the imminent risk of destruction for at least 31 Alaskan towns and cities. Many are predicted to become uninhabitable over the next few decades. Residents of these places are likely to join the growing flow of climate refugees around the globe.
There are 35 megacities in the world – metropolitan areas with more than 10 million people. Fifteen of them have populations above 20 million. And many of these teeming metropolises have to contend with some of the worst air pollution on the planet.
The Scottish government has an ambitious plan to meet 100 percent of its demand for electricity from renewable sources by 2020. Like much of the world, Scotland has produced significant amounts of its electricity by burning coal for more than 100 years. But no longer.
China passed the U.S. as the largest emitter of greenhouse gases on Earth back in 2007, mostly due to manufacturing. However, the great majority of all the products China produces are exported to the rest of the world. China’s per capita consumption-based environmental footprint is actually small. If you put the responsibility for environmental impacts on the consumer instead of the producer, we are all the culprits.
According to the National Oceanic and Atmospheric Administration – or NOAA – 2015 was the second hottest year ever recorded in the contiguous United States.
While 195 countries reached agreement on reducing greenhouse gas emissions in December, the city of San Diego made a major commitment of its own. Whereas the Paris climate accord is non-binding, San Diego has gone much further.
