The world is warming up. Both property and oceans are warmer today than record-keeping started in 1880, and temperatures are still ticking upward. This temperature increase, in summary, is global warming. The speed of change has been an extra 0.13 degrees F (0.07 degrees C) per decade, together with the soil surface heating faster than the sea surface -- 0.18 degrees F (0.10 degrees C) versus 0.11 degrees F (0.06 degrees Cmph, respectively. The Paris Agreement, ratified by 159 countries at summer time 2017, intends to stop that heating in 2.7 degrees F (1.5 degrees C) over Earth's average temperature during preindustrial times -- a target most scientists and policy makers agree is going to be a struggle to meet. (The United States engaged in the crafting of the nonbinding treaty under President Barack Obama, however, President Donald Trump has stated that his government won't take part.)
