‘It’s a delicate place’: NASA captures 20 years of Earth’s seasonal changes

NASA has captured 20 years of changing seasons in a striking new global map of planet Earth​.
The data visualization, released this week, shows Earth’s fluctuations as seen from space.
The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance – or lack – of undersea life.
“It’s like watching the Earth breathe. It’s really remarkable,” said NASA oceanographer Jeremy Werdell, who took part in the project.
Two decades – from September 1997 to this past September – are crunched into two and a half minutes of viewing.
​Werdell said the visualization shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the Arctic ice caps receding over time – and, though less obvious, the Antarctic, too.
​In the oceans, Werdell was struck by “this hugely productive bloom of biology” that exploded in the Pacific along the equator from 1997 to 1998 – when a water-warming El Nino merged into cooling La Nina. This algae bloom is evident by a line of bright green.
In considerably smaller Lake Erie, more and more contaminating algae blooms are apparent, appearing red and yellow.
All this data can provide resources for policymakers as well as commercial fishermen and many others, according to Werdell.
Programmer Alex Kekesi of NASA’s Goddard Space Flight Center in Maryland said it took three months to complete the visualization, using satellite imagery.
​The visualization will continually change, officials said, as computer systems improve, new remote-sensing satellites are launched and more observations are made.

Included Countries
  • Angola
  • Austria
  • Belgium
  • Britain
  • Canada
  • Costa Rica
  • Denmark
  • El Salvador
  • Fiji
  • Finland
  • France
  • Italy
  • Luxembourg
  • The Marshall Islands
  • Mexico
  • The Netherlands
  • New Zealand
  • Niue
  • Portugal
  • Switzerland
Twenty countries including Britain, Canada and New Zealand have joined an international alliance to phase out coal from power generation before 2030.
The Powering Past Coal Alliance was unveiled at the COP23 climate talks in Bonn, Germany, which were working out the technical details of the 2015 Paris Agreement.
"I think we can safely say that the response has been overwhelming," Canadian Environment Minister Catherine McKenna said.
"There is so much momentum, there is so much ambition in this room."
The alliance, which isn't legally binding, was launched days after a pro-coal presentation by the Trump administration jarred with many ministers who wanted the talks to focus on cleaner energy sources.
Australia isn't part of the alliance, which also doesn't include some of the world's biggest coal users China, India, the United States, Germany and Russia.
Coal is responsible for more than 40 per cent of global emissions of the greenhouse gas carbon dioxide.
"Around the world we see close to a million deaths a year from air pollution created by burning coal," Ms McKenna said.
"Not only is there a human cost, there is also a huge economic cost totalling billions of dollars a year."
Since signing the Paris Agreement, several countries had already made national plans to phase out coal from their power supply mix.
The Powering Past Coal Alliance also involves sharing technology to reduce emissions, such as carbon capture and storage, and encouraging the rest of the world to cut usage.
The alliance aims to have at least 50 members by the next UN climate summit in 2018 to be held in Poland's Katowice, one of Europe's most polluted cities.
"I hope the room will have to be four times bigger in Katowice, but we are off for a good start," British Environment Minister Claire Perry said.
Meanwhile, the United States told the talks it is committed to reducing greenhouse gas even though the Trump administration still plans to pull out of the Paris Agreement.
In her closing remarks to the conference, the US State Department's Judith Garber said:
"We remain open to the possibility of rejoining [the Paris Agreement] at a later date under terms more favourable to the American people."
The US states of Washington and Oregon have already signed up to the Power Past Coal Alliance.

How Citizens Are Fighting Climate Change On The Global Stage

The Conversation |  |

The United Nations climate conference in Bonn, Germany, is an enormous event with a complex agenda. But here, on the ground, we see that it is much more than just a meeting of the signatories to the Paris Agreement.
Delegates from nearly 200 countries are meeting here to discuss the pathway towards the Paris Agreement, which aims to keep the mean global temperature increase below 2℃, and to prepare for the first global stocktake — a review of countries’ progress towards their climate commitments, in 2018.
At this year’s Conference of the Parties (COP23), as at others, these government delegations will negotiate the wording of texts, debate their differing points of view and seek common ground in intense meetings that are often closed to outsiders.
But there are thousands of other attendees, called observers, milling about the hallways and pavilions, shoulder-to-shoulder with party delegates. These observers come from a wide variety of non-governmental organizations and intergovernmental organizations, representing Indigenous peoples, youth, women, farmers and businesses, to name a few.
These observers represent civil society, not a country’s government. They are also known as “non-state actors” — and their influence at the UN climate negotiations is growing.

Joining efforts
It wasn’t until 2009, at the COP15 in Copenhagen, that the participation of civil society in climate talks was galvanized. Since then, the conventional model of multilateralism, where country delegations talk to each other and non-state actors observe these negotiations, has moved towards an increasingly inclusive space. National and regional delegates are now encouraged to interact with non-state actors in a more collaborative way.
Frank Bainimarama, the Fijian prime minister and COP23 president, has frequently referred to this engagement in his speeches at this year’s meeting. He has said that the non-party actors are essential to helping countries find solutions to climate change mitigation and adaptation.
The newly released Yearbook of Global Climate Action 2017 illustrates how these non-party actors, including cities and regions, can sometimes take action more quickly within their own districts. In recognition, the UN has invited members of observer groups to participate in many of the sub-groups and committees of the UN Framework Convention on Climate Change (UNFCCC) and to work alongside its staff and the parties.

In Bonn, observers have organized panels on diverse aspects of climate change, from forests to human security to ethics and finance. These events showcase climate actions, share expertise and add a dynamic element to the meeting. The members of country delegations have a long history of participating in these panels and discussions.
The pavilions, side events and official panels cover over 50,000 square metres of space. We visited the European Space Agency’s booth to learn about how it is monitoring Greenland’s melting ice sheet and attended a yoga class in the India pavilion to stretch and relax during a long, stressful day.

#WeAreStillIn
This year, the significance and relevance of observers has reached a new peak following the White House’s announcement that the United States will withdraw from the Paris Agreement. For the first time in the history of these talks, the United States declined to host an official pavilion. Its delegation has held only one event, a U.S. government sponsored panel on “clean coal.”

There is, however, a very large presence of non-state actors from the United States. This coalition of governors, mayors, CEOs, universities and religious leaders, including former New York City Mayor Michael Bloomberg, California Governor Jerry Brown and former Vice President Al Gore, have pledged to ensure the United States delivers on its climate commitments.
The America’s Pledge initiative will aggregate and quantify the actions of states, cites, businesses and other non-national groups in the United States to drive down greenhouse gas emissions. This is no small outcome: If the America’s Pledge community were a country, it would be the world’s third largest economy.

A role for academia
There is no shortage of academics, including many students, at the climate change meetings. York University professors, staff and students have attended annual COP meetings since 2009 as part of an observer group known as the Constituency of Research and Independent Non-Governmental Organizations to the UNFCCC (RINGO).
RINGOs advocate for the use of the best available research — from science, technology, engineering, mathematics, social sciences and humanities — to inform climate policy. In Bonn, we have been meeting first thing every morning. At one meeting this week, we learned how our daily summaries of the negotiations have been a valuable resource for other civil society groups such as environmental non-governmental organizations.
These meetings provide students with the chance to learn about the negotiation process by being involved in it. For professors, they’re an opportunity to provide experiential education, and to design classes around the climate change meetings.

Intersections and interactions
The near-constant news conferences provide a clear picture of how RINGOs and other NGOs influence the parties and the negotiations.
Speakers from diverse constituencies launch policy and research reports at these events. Earlier this week, the Civil Society Review, a group of 120 organizations, released their assessment of global climate change commitments. The panelists explained that countries cannot delay action on climate change because it is already affecting the world’s most vulnerable peoples. Their message was clear and accessible.
Many observers and delegates from less-developed countries are displaying frustration at the slow progress on some of the COP23 agenda items. During the news conference, a climate scientist in the audience asked the panel whether civil society should abandon the UNFCCC process. The panelists were unanimous in saying that civil society should continue to work with the UN framework.
“There is no space other than the UNFCCC where we can talk about multilateral finance for developing countries. Developed countries are, currently, just not willing to discuss loss and damage finance,” said Brandon Wu, director of policy and campaigns at ActionAid USA.
Despite the progress made with the Paris Agreement, the task ahead remains formidable. According to Carbon Budget, CO2 emissions are rising again following three years of stability. There is still much work to do on adaptation, climate finance and protecting the countries most vulnerable to the adverse effects of climate change. This work does not always go smoothly. Nevertheless, observers are clearly cautiously optimistic.
