Normally, cloud bottoms are flat. This is because moist warm air that rises and cools will condense into water droplets at a specific temperature, which usually corresponds to a very specific height. As water droplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm. Resulting mammatus clouds can appear especially dramatic if sunlit from the side. The mammatus clouds pictured here, lasting only a few minutes, were photographed over Regina, Saskatchewan, Canada, just after a storm in 2012.</p><p><a href="https://apod.nasa.gov/apod/ap210811.html" rel="nofollow" class="ellipsis" title="apod.nasa.gov/apod/ap210811.html"><span class="invisible">https://</span><span class="ellipsis">apod.nasa.gov/apod/ap210811.ht</span><span class="invisible">ml</span></a></p><p><a href="/tags/space/" rel="tag">#space</a> <a href="/tags/earth/" rel="tag">#earth</a> <a href="/tags/atmophere/" rel="tag">#atmophere</a> <a href="/tags/clouds/" rel="tag">#clouds</a> <a href="/tags/weather/" rel="tag">#weather</a> <a href="/tags/photography/" rel="tag">#photography</a> <a href="/tags/science/" rel="tag">#science</a> <a href="/tags/physics/" rel="tag">#physics</a> <a href="/tags/meteorology/" rel="tag">#meteorology</a> <a href="/tags/nature/" rel="tag">#nature</a></p>

<p>We will shoot past the 1.5°C target, averaged over 20 years, by the end of this decade. There’s no way to prevent it.</p><p>After that, to avoid 2C, 3C, or even 4C, it will take a massive and — dare we say? — highly unlikely global effort to unite in slashing carbon emissions at an unprecedented rate.<br>__________________________________</p><p>For global average temperatures to stabilize at less than 1.5°C above preindustrial levels, humanity needs to achieve 43% greenhouse gas emissions cuts by 2030. But progress on climate action has stagnated in recent years, global GHG emissions are yet to peak, and our remaining carbon budget is dwindling.</p><p>Above 1.5°C of warming, we risk passing critical tipping points in natural Earth systems, triggering self-perpetuating changes that could shift the planet out of the habitable zone for humanity and for life as we know it.

<p>A really interesting paper just came out in Science a few weeks ago: <a href="https://www.science.org/doi/10.1126/science.adv9472" rel="nofollow" class="ellipsis" title="www.science.org/doi/10.1126/science.adv9472"><span class="invisible">https://</span><span class="ellipsis">www.science.org/doi/10.1126/sc</span><span class="invisible">ience.adv9472</span></a></p><p>The authors compared satellite measurements of <a href="/tags/lightpollution/" rel="tag">#LightPollution</a> from <a href="/tags/viirs_dnb/" rel="tag">#VIIRS_DNB</a> to 2.6 million bird calls recorded at 7,824 locations around the world. They show not only that birds sing longer at both morning and night in areas that are brighter, but that the response is different for different species.</p><p>For example, species with larger eyes are more strongly affected, and species that nest in cavities (protected from light exposure) are less affected.</p><p>Very cool work!</p><p><a href="/tags/remotesensing/" rel="tag">#RemoteSensing</a> <a href="/tags/globalenvironmentalchange/" rel="tag">#GlobalEnvironmentalChange</a> <a href="/tags/birds/" rel="tag">#Birds</a> <a href="/tags/science/" rel="tag">#Science</a></p>
