  • Last year was the second-hottest year on record, behind only 2016, when temperatures were influenced by El Niño. The past decade was also the warmest decade on record. 
  • Last year also set a record for ocean temperatures. High ocean temperatures are harmful for marine life and also affect weather on land.
  • The Trump administration has been dismantling the management of the National Park Service and undermining the regulations that protect them.
  • Most of the political appointees in charge of enforcing federal environmental laws have a background in the fossil fuel or agricultural industries or worked to undermine regulations in a state government.
  • New Jersey legislators failed to pass the single-use plastic ban or a bill to protect Liberty State Park from development before the end of the last session. (The latter passed the state senate but died in the assembly.) The process for both will need to be restarted.

  • The number of Gurney's Pittas has declined rapidly since surveys in 2003. Major threats include the wildlife trade (pittas get caught in traps for pangolins) and deforestation (primarily for palm oil plantations).
  • The most colorful coot chicks tend to be the most vulnerable, and the bright colors can get adult coots to feed them more.
  • Hooded Grebes are threatened by introduced American Mink and Rainbow Trout as well as increasing predation from Kelp Gulls.A conservation program includes guardians to watch over the nesting colonies.
  • As the climate warms and more people provide feeders, increasing numbers of Ruby-throated Hummingbirds are overwintering in the Carolinas.
  • Two Spoon-billed Sandpiper chicks have hatched in England as part of a captive-breeding program. So far the program has not successfully fledged any chicks.
  • A zoo in India is raising endangered Greater Adjutant chicks as part of a captive-breeding program.
  • About 5,000 Golden Eagles winter east of the Mississippi according to new estimates.
  • Vultures in Zululand, South Africa, suffered their four mass poisonings in 2019.

  • A survey last summer found an increase in the number of endangered Seabeach Amaranth plants on New Jersey's beaches. Protection zones at Island Beach State Park and elsewhere have allowed the plants to thrive and also benefit beach-nesting birds.
  • The Natural History Museum in Britain announced that their scientists named 412 new species in 2019
  • Conifers rely on their existing root systems during times of drought rather than growing new, deeper roots.

Climate change and environmental politics
  • A report on the state of the Arctic found numerous concerning changes, from record high temperatures to rapid melting of Greenland's ice sheet to thawing permafrost.
  • Meanwhile, bushfires in Australia have emitted a massive amount of carbon dioxide into the atmosphere, equal to almost half of the country's annual emissions.
  • Addressing climate change will require a reduction in meat and dairy consumption; "peak meat" will probably need to happen by 2030 in wealthier countries.
  • Activists were frustrated that climate justice is not being given greater attention at the UN climate talks in Madrid. 
  • An EU commission proposed a European Green Deal to help the European economy reduce its emissions and adapt to climate change.
  • New York lost its climate change case against Exxon Mobil this week. The state argued that the company misled shareholders about the cost of climate change.
  • The fracking boom has spurred the development of new plants that convert shale gas to plastic, and communities near the new plants are finding tiny plastic pellets in watersheds around the plants.
  • Recycling of electronic waste is mostly done in Southeast Asia, often by people working for low pay in dangerous working conditions.
  • In East Coast cities like Washington, climate change is reducing the average seasonal snowfall but increasing the potential for monster snowstorms.
  • It seems that New Jersey's proposed single-use plastics ban might be stalled again due to lobbying from the plastics industry. 
  • The proposed Atlantic Coast Pipeline would cut through the Appalachians and Piedmont to carry fracked gas to southeast North Carolina. Construction is currently held up because of lawsuits over the pipeline's environmental impacts, including to the Appalachian Trail.

  • New genetic research using museum specimens finds that the extinction of the Great Auk was a result of overhunting and not due to environmental change or inbreeding.
  • This week a Ross's Gull, extremely rare in the Lower 48, was seen by birders in Seattle, but a Bald Eagle caught and ate it. Photos and details about the gull, including its final moments, are in this checklist and this checklist (and several others) on eBird. 
  • A study using specimens of 52 bird species that struck buildings in Chicago from 1978 to 2016 found that body size decreased in all 52 species and wing length increased in 40 species, which is consistent with warming temperatures.
  • Higher temperatures have increased the daily water intake of birds in the Mojave Desert, which could reduce their populations if climate change worsens.
  • The availability of cheap recording devices and data storage is making it easier to monitor wildlife sounds in places where it would be expensive or time-consuming to conduct on-the-ground surveys. Birds especially can be studied this way, but it can also be used for frogs and toads, whales, some insects, and other groups. Some software can already identify vocalizations on the recordings to species.
  • More frequent wildfires may threaten Northern Goshawks in the Sierra Nevadas since the hawks avoid nesting in areas with severe burns. 
  • A report finds that Australia's threatened birds declined by an average of 59% over the past 30 years, with some groups faring worse. Migratory shorebirds, for example, declined by 72%. 
  • A captive-breeding program is starting to return Alagoas Curassows to Brazil's Atlantic Forest, with three pairs released this fall.
  • Chinstrap Penguins have a harder time adapting to environmental changes than Gentoo Penguins because of their more specialized diet.
  • Wild Turkeys come in a variety of color morphs.
  • Feral Monk Parakeets have continued to thrive in Bergen County after escaping from captivity 30 years ago.

  • Forest fragmentation puts wildlife in danger, especially in places where animals are used to having stable habitats.
  • The IUCN is creating a Green List that will evaluate how well threatened species have recovered. Some species, like the American Bison, are no longer in danger of extinction but are nowhere near their historical population levels.
  • LED lights on gillnets may reduce bycatch of sea turtles and dolphins.
  • For now at least, it seems New Jersey has avoided the spread of invasive pond mussels via a fish farm in Hunterdon County. The mussels can get very large, but their larvae can ride in the gills of invasive carp.

  • This year's Emissions Gap Report from the UN finds that global emissions have risen by 1.5% per year over the past decade and that nations must increase their emissions cuts because the cuts pledged under the Paris Agreement would result in a temperature increase of 3.2°C. 
  • Countries with the biggest emissions increases are all in Asia, but a disproportionately large share still comes from the United States, which accounts for 14.5% of global carbon emissions.
  • Early climate change models were impressively accurate according to a new paper.
  • The National Butterfly Center won an injunction against a private group trying to building a wall along the Rio Grande.
  • California set a moratorium on dropping insurance coverage in fire-prone areas, which is a window into the problems insurance companies are having with adapting to climate change.
  • The Recovering America’s Wildlife Act of 2019 advanced out of committee in the House of Representatives. The bill would provide money to states, territories, and DC to implement their wildlife conservation plans.
  • The federal government recently released a report on Superfund sites that might be threatened by climate change, and 24 are in the Lower Raritan Watershed.
  • New Jersey may finally pass broad restrictions on disposable plastic items after the legislation sat in limbo for months.
  • California's plastics law reduced plastic bag use by 80%, but many stores still offer slightly thicker plastic bags.
  • The Surfrider Foundation gave New Jersey a D- in its evaluation of how coastal communities are handling climate change adaptation. While the report praised the Blue Acres program, it found permitting and building standards were too lenient in flood-prone areas and too much emphasis was put on beach replenishment and seawalls.
