    Story of the Week - Satellite confirms key NASA temperature data:  The planet is warming — and fast Story of the Week - Satellite confirms key NASA temperature data:  The planet is warming — and fast New evidence suggests one of the most important climate change data sets is getting the right answer. New evidence suggests one of the most important climate change data sets is getting the right answer.A high-profile NASA temperature data set, which has pronounced the last five years the hottest on record and the globe a full degree Celsius warmer than in the late 1800s, has found new backing from independent satellite records — suggesting the findings are on a sound footing, scientists reported Tuesday. If anything, the researchers found, the pace of climate change could be somewhat more severe than previously acknowledged, at least in the fastest warming part of the world — its highest latitudes. “We may actually have been underestimating how much warmer [the Arctic’s] been getting,” said Gavin Schmidt, who directs NASA’s Goddard Institute for Space Studies, which keeps the temperature data, and who was a co-author of the new study released in Environmental Research Letters.  Read original at https://www.washingtonpost.com/climate-environment/2019/04/17/satellite-confirms-key-nasa-temperature-data-planet-is-warming-fast/

  • Jay Inslee’s Pitch for All-Climate Change Debate Gains Traction

    Climate Change News Apr 21, 2019 | 06:48 am

    Jay Inslee’s Pitch for All-Climate Change Debate Gains Traction Environmental groups say Americans have a right to know how Democrats plan to address climate change before the 2020 voting. A proposal from Washington Gov. Jay Inslee to have a presidential debate focused on climate change gained steam on Wednesday with backing from a rival 2020 candidate and a coalition of environmental groups. Inslee on Tuesday called on the Democratic National Committee to host an all-climate debate during the 2020 primary campaign season.  The governor, who is centering his presidential campaign around climate change, said in an email to supporters that the Democratic nominee selected to challenge President Donald Trump needed to have a “concrete plan to address” the phenomenon, and that American’s deserved to hear it in advance of the primaries. “Climate change is at the heart of every issue that matters to voters, and voters deserve to hear what 2020 presidential candidates plan to do about it,” Inslee wrote in the email, first reported by The Daily Beast. Most Democrats in the crowded field have made climate change a core tenet of their campaigns, in direct opposition to Trump’s climate-denying policies.  The White House has dramatically rolled back many environmental regulations and moved to withdraw the U.S. from the landmark Paris Climate Agreement as Trump himself has mocked the science around the issue.

  • Saving Ecosystems to Protect the Climate, and Vice Versa:  a Global Deal for Nature

    Climate Change News Apr 21, 2019 | 06:36 am

    Saving Ecosystems to Protect the Climate, and Vice Versa:  a Global Deal for Nature A new study combines two approaches: protecting ecosystems like forests and tundra to combat climate change, and fighting climate change to protect ecosystems. For years, experts in conservation and climate science have urgently pursued two parallel paths—one to interrupt a large-scale extinction event, the other to avert a runaway climate crisis. Now, an international group of scientists is proposing a third way that marries the two in an ambitious plan they hope will save the species that make our planet so rich—including ourselves. They set out their timetable in a paper released Friday in the journal Science Advances calling for a "Global Deal for Nature."  Its unified objective: protect the ecosystems to combat climate change; combat climate change to protect the ecosystems. It aims to set aside 30 percent of the planet's lands for various degrees of protection from development and destruction by 2030, with additional protections for another 20 percent.  It also sets goals for conservation in oceans and freshwater ecosystems.

  • Electric Cars Could Be as Affordable as Conventional Vehicles in Just Three Years

    Climate Change News Apr 20, 2019 | 03:01 am

    Electric Cars Could Be as Affordable as Conventional Vehicles in Just Three Years Electric vehicles will be cost-competitive with combustion-engine cars by 2022, according to a new report by transportation analysts at Bloomberg New Energy Finance (BNEF).  The trend is due to the plunging price of EV batteries.  Batteries made up 57 percent of an electric vehicle’s total costs in 2015.  Today, that number is down to 33 percent, and it is expected to drop to 20 percent by 2025. The new forecast highlights the rapid development of EV technologies globally.  BNEF first suggested in 2017 that electric cars would become cost-competitive with conventional cars in 2026.  A year later, BNEF changed it to 2024.  The analysts argue that this competitive pricing will allow customers to make a choice between a combustion or electric car based on style, performance, and preference — not cost. BNEF also notes that the cost of electric powertrain systems is also dropping.  By 2030, costs for motors, inverters, and power electronics could be 25 to 30 percent cheaper than today.  The affordability of EVs will also be helped by a modest rise in costs for combustion vehicles as they utilize lighter-weight materials or other technologies to meet fuel efficiency targets. And as Nathaniel Bullard, an analyst with BNEF, writes on Bloomberg Opinion, cheaper electric vehicle batteries don’t “just mean cheaper electric passenger cars.  It also means all sorts of other vehicles that weren’t previously practical to electrify now are.”  Bullard points to a new all-electric excavator developed by Komatsu Ltd., Asia’s top construction equipment maker.

  • Climate Science Supports Youth Protests

    Climate Change News Apr 20, 2019 | 02:45 am

    Climate Science Supports Youth Protests The youth protests urging political action on climate change have won strong global backing from climatologists, as over 6,000 scientists express their support. The global youth protests demanding action on climate change are having a marked effect. In their thousands, concerned climate scientists, backed by colleagues from other disciplines, are voicing support for the school students and other young people who are staying away from lessons to urge more resolute political action to protect the climate. The campaign to support the protesters has been launched by an international group of 22 scientists spanning a range of disciplines; several of them are renowned climate specialists. They include Michael Mann, professor of atmospheric science at Penn State University, US, Kevin Anderson, professor of energy and climate change at the University of Manchester, UK, and Stefan Rahmstorf.

  • Extreme Heat Is Growing Threat to Harvests

    Climate Change News Apr 20, 2019 | 02:32 am

    Extreme Heat Is Growing Threat to Harvests A warmer world means more chance of extreme heat in more than one continent at the same time, and a rising threat to global food security. Ever-higher average global temperatures mean more intense extreme heat over ever-wider regions. When the planet becomes on average 1.5°C warmer than it was for most of human history, then for two out of every three years, one-fourth of the northern hemisphere will experience the kind of blistering heat waves recorded in 2018. And should planetary average temperatures creep up by 2°C – the maximum proposed by 195 nations at the global climate conference in Paris in 2015 – then the probability rises to 100%.  That is, extreme heat over a large area of the hemisphere will be guaranteed every summer. Heat extremes are all too often accompanied by devastating thunderstorms or extended drought and massive outbreaks of wildfire, with potentially disastrous consequences for harvests in the blighted regions.
