After all, it is reasonably suspicious that, after persisting for more than a hundred centuries, the ice began to vanish in the very century in which humans started to change the environment both globally and, perhaps more important, locally. It may well be that a regional change of some sort -- deforestation, in all likelihood -- has dried out the moist, rising winds that used to replenish the ice.
This unfailing, uninterrupted life demonstrates that the planet is far from fragile. The living Earth is tough on scales it is hard to credit. Life has watched continents crash together and tear themselves apart; skies glowing like bright coals; tropical seas frozen into stillness: it has endured. Slaked in radiation from nearby supernovae, pummeled by asteroids, it has barely faltered and never stopped.
Note that it is indeed an addition, not a replacement. Neither Keith nor, as far as I know, any of the other researchers looking at the feasibility, side effects, and safety of solar geoengineering sees it as a possible alternative to reducing greenhouse gas emissions. For long-term climate stability, fossil-fuel greenhouse gas emissions have to be brought down to zero; they need to come down to zero to put an end to ocean acidification, too.
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 Musk AND Zuckerberg or Musk + Zuckerberg.
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, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
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".
