Our environment correspondent Matt McGrath looks at five critical questions now facing the Nobel prize-winning Intergovernmental Panel on Climate Change (IPCC) as it prepares to present its latest report in Stockholm later this week. The IPCC - weren't they the ones who said the Himalayan glaciers would disappear by 2035? How can we trust what they say this time? The weight given to the reports of the IPCC is a measure of the global scale of scientific involvement with the panel.
Leading researchers have condemned attempts to change the way carbon from trees will be counted in Europe. The scientists fear that millions of tonnes of CO2 from forests will disappear from the books if the changes go ahead. Trees are important carbon sinks as they soak up about 10% of Europe's emissions every year. But some countries want to cut more trees down in future without counting the resulting loss of carbon.
Speaking to the European Parliament, Jean-Claude Juncker categorically ruled out any re-negotiation of the Paris climate agreement. The European Commission President said: "We have spent 20 years negotiating", and now was the time for implementation. US President Trump has claimed that the accord could be amended and made more palatable to his country. Mr Trump announced earlier this month that the US would leave the pact.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Obama AND Romney or Obama + Romney.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used.) For example, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
