If the temperatures are increasing in a mountainous region, in order to be sure in that, the evidence can simply be obtained by the vegetation. The mountains tend to be warmer at the lower parts, and as the elevation increases, the temperature decreases. If it is a higher mountain, then we will see that there is certain type of vegetation in the lower parts, above it a belt of another vegetation type, above that one there's usually a belt of grasses, and the highest parts are usually with little to no vegetation. If the temperature increases though, then the vegetation from the bottom will start moving upwards, occupying larger portion, the second layer will move upwards as well, and the grasses will come around the top part of the mountain, with the barren part disappearing from the scene.
"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>

If air pressure rises, a high pressure cell is on the way and clear skies can be expected. If pressure falls, a low pressure cell is coming and will likely bring storm clouds. Barometric pressure data over a larger area can be used to identify pressure systems, fronts, and other weather systems.
Hope this helps.
