1. Panel Intergovernmental Panel on Climate Change (IPCC) issued "special report global warming 1.5 ° C"
2018On October 8 Panel Intergovernmental Panel on Climate Change (IPCC) published "Global warming 1.5ºC Special Report"。Report sounding the alarm，He stressed the urgent need to take drastic measures，Prevent global warming Chaoguo 1.5 ° C。The report said，If global warming continues at the current pace，The world faces unprecedented environmental challenges。Expected global temperature will rise 1.5 ° C between 2030 and 2052 than in pre-industrial levels。
Report says，To achieve global temperature rise within 1.5 ° C goal，Land countries around the world、energy、industry、building、All levels of transportation and urban planning should quickly advance "deep and wide" changes，Net emissions of carbon dioxide to make in order to 2030 than 2010 levels by 45%，2050In order to achieve "zero net emissions"，I.e., carbon dioxide emissions and the like of the cancellation amount。

2. Limit the use of disposable plastic has become a trend
2018year，Reduce the production and use of plastics，Particularly disposable plastic，We have made considerable momentum。United Nations Environment Program and the World Resources Institute, a recent report shows，127 countries have clear policies to manage plastic bags。The report said，"These policies include the manufacturing of plastic bags，Distribution，Restrictions on the use and trade，Tax and taxation as well as disposal after use. "，And may vary by country，But "the most common form is to limit the free retail distribution。"source： Earth Island Journal
3. The most deadly fires occurred in California history
California ever witnessed deadly and destructive wildfire seasons。Two combined extreme rainfall climate (2017 record rainfall) and followed by a very hot summer，North end of June to August of California, a wildfire broke out leaving conditions can easily spread (hay and other dry bushes)。Carr includes more than a thousand houses destroyed by the fire near the city of Redding，And burning more than 459,000 acres of Mendocino Complex fire。Fire caused a total of 85 people were killed，249Missing，Is the history of California's most deadly fire。source: Earth Island Journal
4. United States to promote Green New Deal
After the skeptics of climate change US President Trump and the world's second largest greenhouse gas emitters plan to withdraw from the Paris agreement，The limit global warming to 1.5 degrees Celsius would be a daunting task，That's why environmentalists hope will be successful in the new US climate plan "Green New Deal"。Democrat superstar Alexander·Ocasio·Cortes promote "green New Deal"，The United States plans to push 100% clean energy。Some members of Congress pledged support。source： Eco Warrior Princesses
5. Tianjin was first introduced thermal power flue gas temperature emission limits
The most stringent air emission standards coming! Tianjin release 2018 standard atmospheric thermal power，Temperature flue gas emission limit for the first time! Tianjin in June 2018 issued a compulsory local standards "thermal power plant air pollutant emission standards" (DB12 / 810-2018)，This is the first place in the atmosphere to make a standard thermal power plant flue gas discharge temperature limit，Standard April - October temperature flue gas emissions of coal-fired boilers ≤48 ℃，11- March ≤45 °。Defining a flue gas discharge temperature is made in-depth treatment for condensing flue gas wet desulphurization white emission，The white smoke is also known as "colored plume"， It is considered to be an important cause of increased haze。In addition to Tianjin，Shanghai， Zhejiang， Hebei， Shanxi， Henan， Jiangxi Province， Xuzhou and other provinces also issued similar regulations，Requirements governance "colored plume"。source：Ash desulfurization and denitration technology alliance
6. The ozone layer is being repaired
Seventies of the last century，Scientists have discovered a name of chlorofluorocarbon (CFC) chemicals is undermining the Earth's fragile ozone layer，The Antarctic ozone hole startling discovery further exacerbated the urgency of the problem。1989In it signed the "Montreal Protocol on Ozone Depleting Substances" by the States of the United Nations Organization，It aims to controlled substances chlorofluorocarbons，Ozone Layer Protection。The agreement is an international environmental agreement in the best performing。2018November，Conference of the Parties thirtieth "Montreal Protocol", published on the quadrennial review of the Protocol - the "2018 Scientific Assessment of Ozone depletion" confirmed，The ozone hole is completely healed and could resume in 2060。This is a great victory for the environmental movement。Moreover，"Montreal Protocol" and "Kigali amendment" came into force on January 1, 2019。The amendment calls for a gradual phase-out of the refrigerator、Production and use of air conditioning and related products potent greenhouse gases HFCs。The above assessment report noted，Out of HFCs 0.5 degree Celsius temperature rise can be avoided。And out and replaced in the same time HFCs，Air conditioners and other refrigeration equipment to improve energy efficiency gains can be doubled climate。It has a vital role for global climate security source： UN News
7. Investment in renewable energy set a new record
Fossil fuel companies and their political followers may try to stop the progress of renewable energy，But the free market forces even greater。After the investment until 2017 to break the record，Government and commercial companies to invest in renewable energy to new highs。In Australia，Renewable energy projects and investment of US $ 20 billion，In the United States，The EU and China，Bioenergy，Solar，The number of wind and hydropower projects record high。"Renewable energy will continue to expand over the next five years，Coverage of global energy consumption growth of 40%，"The International Energy Agency said in October press release to。 "Their use in the power sector continues to grow fastest，And accounted for in 2023 the world's total generating capacity of nearly one-third。"More gratifying is，International Energy Agency, China is recognized worldwide leader in renewable revolution，"Because of all government departments and local governments to perform low-carbon action are efforts to reduce local air pollution."。Global Energy Agency forecast，China will become the largest consumer of renewable energy，2023 will exceed the EU。Since China is the world's largest emitter of greenhouse gases，This news for China and the world environmental action is significant。

8. The scientists called for eight measures to increase soil carbon content
Increasing carbon content in the soil can significantly reduce greenhouse gas emissions from human activities into the atmosphere。In the meeting held on the occasion of the UNFCCC climate negotiations，Scientists propose eight steps to increase global soil organic carbon storage。And this eight measures will also be a seminar Koronivia Joint Work on Agriculture, held in June 2019 focuses on the topic。
This is followed by eight steps：1.Stop carbon content reduction。Through the implementation of regulations to protect the drainage and burning peatland。2.Promote carbon sequestration。To promote measures that are appropriate to local conditions，Including contour plowing，Terraces，Nitrogen-fixing plants and irrigation。3.Monitor and verify the impact。Using scientific standards to track and evaluate。4.Deployment technology。 Using high-tech opportunities faster，cheaper，Monitor soil carbon changes more accurately。5.Test strategy。By using the model and the site network，Determine the most effective method under local conditions。6.To involve the community。 The use of science to collect data and create an open online platform for sharing。7.Policy coordination。The climate and soil carbon commitment "Paris Agreement" and other climate-related policies and combined。8.provide support。Ensuring that technical assistance，To promote the wide implementation。

9. 15Year-old small "environmental activists" aboard the UN stage
15Year-old Swedish climate activist Greta·Tuenboge (Greta Thunberg) speech at the UN climate change summit COP24 2018 held in Poland，Inspire a new generation of young people to join the movement to combat climate change。she says，"2078，I will celebrate my 75th birthday。If I have children，Maybe they will and I spent the day together。Maybe they'll ask me something about you。Maybe they'll ask，Why there is still time to take action when you do not have to do anything。You say you love your children above all else，But you have in front of them stole their future。"source：Eco Worrier Princess
10.China once again to "foreign garbage" Say No
China imposed a ban in July 2017 of "foreign garbage，Namely plastic waste from domestic sources of (eight kinds)、Unsorted waste paper (one kind)、Waste textile raw materials (11 kinds) and vanadium slag (four kinds)。The import ban has been effective from December 31, 2017。Chinese Ministry of Commerce recently said，China since the end of 2018 will ban another 16 kinds of scrap metal、Chemical waste imports。2019Since the end will also be prohibited waste and scrap of stainless steel、Titanium waste and scrap、Imported wood waste and scrap and other 16 varieties of solid waste。
China to ban imports of foreign garbage of European countries on the one hand increases the cost of waste disposal，European countries on the other hand also increased the capacity for sorting and recycling waste。
